Section 4 Surveys – General

4.1 New construction

4.1.1 When it is intended to build a ship for Classification with LR, constructional plans and all particulars relevant to the hull, equipment and machinery, as detailed in the Rules, are to be submitted for the approval of LR before the work is commenced. Critical Areas (see Vol 1, Pt 1, Ch 3, 1.5 Definitions 1.5.4) will be identified at this stage. Any additional plans submitted will not be subject to appraisal or approval without separate agreement. Proposals for any subsequent modifications or additions to the scantlings, arrangements or equipment shown on the approved plans are also to be submitted in writing and on plans for approval.

4.1.2 Where the proposed construction of any part of the hull or machinery is of novel design, or involves the use of unusual material, or where experience has not sufficiently justified the principle or mode of application involved, special tests or examinations before and during service may be required. In such cases a suitable notation may be entered in the vessel’s Classification record.

4.1.3 The materials used in the construction of hulls and machinery intended for Classification are to be of good quality and free from defects and are to comply with the requirements of the Rules. Material is to be manufactured at a works approved by LR. Alternatively, tests to the satisfaction of LR will be required to demonstrate the suitability of the material.

4.1.4 Copies of the latest approved plans, essential certificates and records, required loading and other instruction manuals are to be readily available for use when required by the attending Surveyors and are thereafter required to be kept on board.

4.1.5 Where requested, LR will check the intact and damage stability calculations and approve the Stability information in accordance with the agreed standard(s).

4.1.6  Fire Protection – FIRE. The arrangements for fire protection, detection and extinction are to be examined to ensure that the following fire protection objectives have been satisfied:

  1. Fire Prevention Objective. The ship is to be designed and equipped so as to reduce the risk of the occurrence of fire or explosion, taking due account of its civil and military operational role.

  2. Fire Detection Objective. The ship is to be designed and equipped, as far as is practicable, to detect any potentially hazardous fire or explosion.

  3. Fire Extinguishing Objective. The ship is to be equipped, so far as is practicable, so that all detected fires can be safely and effectively extinguished.

  4. Containment Objective. The ship is to be arranged, so far as is practicable, to limit the spread of fire, smoke and toxic by-products to the space of origin.

  5. Personnel Hazard Objective. All reasonable measures are to be taken to prevent hazards to personnel as a result of fire.

  6. System Interaction Objective. The possibility of fire protection measures or systems causing fire related, or non-fire related hazards is to be kept to a level that is as low as is reasonably practicable.

  7. Command and Control Objective. Suitable means are to be provided to ensure any active fire control measures can be safely and effectively orchestrated.

  8. Structural Integrity Objective. Sufficient structural integrity is to be maintained following a fire so as to prevent the whole or partial collapse of the ship’s structures due to strength deterioration by heat.

4.1.7  Pollution Prevention – POL (Optional)

The arrangements for prevention of pollution of the sea and air from the ship are to be examined to ensure that the following MARPOL - International Convention for the Prevention of Pollution from Ships Regulations have been complied with:

  1. MARPOL Annex I of MARPOL 73/78Regulations for the Prevention of Pollution by Oil (Prevention of Pollution by Oil)

  2. MARPOL Annex V of MARPOL 73/78Regulations for the Prevention of Pollution by Garbage from Ships (Prevention of Pollution by Garbage)

  3. MARPOL Annex IV of MARPOL 73/78Regulations for the Prevention of Pollution by Sewage from Ships (Prevention of Pollution by Sewage)

  4. MARPOL Annex VI - Regulations for the Prevention of Air Pollution from Ships (Prevention of Air Pollution)

4.1.8  Life-Saving and Evacuation – LSAE

The arrangements for life-saving and evacuation are to be examined to ensure that the following life-saving and evacuation objectives have been satisfied:

  1. Evacuation Objective. Arrangements are to be provided to enable personnel to evacuate the ship safely and in a time acceptable to the Naval Administration.

  2. Personnel Protection Objective. Evacuated personnel are to be kept protected until such time as they can be rescued from the survival craft.

  3. Rescue Objective. The ship is to be suitably equipped to rescue personnel from the water.

  4. Command and Control Objective. The ship is to be equipped and manned so that command of all evacuation and life-saving situations can be maintained.

4.1.9  Escape and Emergency Access – ESC

The arrangements for escape and emergency access are to be examined to ensure the following escape of personnel and emergency access objectives have been satisfied:

  1. Escape of Personnel Objective. The ship is to be arranged so that all spaces have means of safe and effective escape for personnel to a designated place of safety, during reasonably forseeable emergency situations.

  2. Emergency Access Objective. The ship is to be arranged so that personnel can access all areas with necessary equipment, for damage control and fire-fighting purposes and exercises.

4.1.10  Safety of Navigation and Communications – SNC

The arrangements for the safety of navigation and communications are to be examined to ensure the following safety of navigation and communication objectives have been satisfied:

  1. Communication Objective. The ship is to be capable of communication to avert unnecessary danger to itself and other ships in the vicinity during normal and emergency conditions.

  2. Safety of Navigation Objective. The ship is to be arranged with the necessary equipment to facilitate safe and effective navigation.

  3. Equipment Arrangements Objective. All navigation and communications equipment is to be arranged to allow safe and effective task performance.

4.1.11  Escape, Emergency Access, Evacuation and Rescue – ERR The arrangements for the integration of the requirements for compliance with the FIRE, ESC and LSAE notations are to be examined to ensure that the arrangements support safe and effective task performance.

4.2 Survey

4.2.1 The Surveyor is to be satisfied that the capability, organisation and facilities of the Builder are such that acceptable standards can be obtained for the construction of the ship and machinery.

4.2.2 In addition to Vol 1, Pt 1, Ch 2, 4.1 New construction 4.1.3, the hull construction of ships is to be controlled by a documented quality control system covering the Builder’s management, organisation and relevant construction processes and inspection procedures.

4.2.3 New ships intended for Classification are to be built under Naval Class Special Survey. The Surveyors are to be satisfied that the materials, workmanship and arrangements are in accordance with the Rules. Any items found not to be in accordance with the Rules or the approved plans, or any material, workmanship or arrangements found so to be, are to be rectified or concession sought from LR.

4.2.4 For compliance with Vol 1, Pt 1, Ch 2, 4.2 Survey 4.2.3, LR will consider methods of survey and inspection for hull construction which formally include procedures involving the shipyard management, organisation and quality systems.

4.2.5 The Surveyor will prepare a report C11(N) record of hull and superstructure watertight, weathertight arrangements and closing appliances.

4.2.6 The date of completion of the Special Survey during construction of ships built under LR’s supervision will normally be taken as the date of build to be entered in the Register Book. If the period between launching and commissioning is, for any reason, unduly prolonged, the dates of launching and completion or commissioning may be separately indicated in the Register Book.

4.2.7 When a ship, upon completion, is not immediately commissioned but is laid-up for a period, LR, upon application by the Owner, prior to the ship proceeding to sea, will direct an examination to be made by the Surveyors which may include a survey in dry dock. If, as the result of such survey, the hull and machinery are reported in all respects in accordance with applicable Rule requirements, the subsequent Special Survey and Complete Survey of the machinery will date from the time of such examination.

4.3 Existing ships

4.3.1  Classification of ships not built under LR survey. The requirements of LR for the Classification of ships which have not been built under LR’s Survey are indicated in Vol 1, Pt 1, Ch 3, 15 Classification of ships not built under LR survey. Special consideration will be given to ships that have been designed, constructed and maintained to specified standards, and to ships transferring Class to LR from another recognised Classification Society who have appropriate Naval Ship Rules.

4.3.2  Classification of ships built under survey to Classification Rules and Regulations other than LR Naval Ship Rules and Regulations. The requirements of LR for the Classification of ships and craft which have not been built under LR's Survey to the LR Rules and Regulations for the Classification of Naval Ships are indicated in Vol 1, Pt 1, Ch 3, 16 Classification of ships built under survey to LR Classification Rules and Regulations other than LR Naval Ship Rules and Regulations

4.3.3  Reclassification. When reclassification or Class reinstatement is requested for a ship for which the Class previously assigned by LR has been withdrawn or suspended, LR will direct that a survey, appropriate to the age of the ship and the circumstances of the case, be carried out by Surveyors. If, at such survey, the ship is found or placed in a good and efficient condition in accordance with the Rules and Regulations, LR will be prepared to consider reinstatement of the original Class or the assignment of such other Class as may be deemed appropriate. The date of any reclassification will be recorded in the vessel’s Classification record. When the original classification was not to the Rules for Naval Ships, then it will be necessary to demonstrate compliance with the additional requirements of these Rules.

4.3.4 LR reserves the right to decline an application for Classification or reclassification where the prior history or condition of the ship indicates this to be appropriate.

4.4 Damages, repairs and alterations

4.4.1 All repairs to hull, equipment and machinery which may be required in order that a ship may retain Class, see Vol 1, Pt 1, Ch 2, 1.1 Framework of Classification 1.1.7, are to be carried out to the satisfaction of the Surveyors. When repairs are effected at a port, terminal or location where the services of a Surveyor to LR are not available, the repairs are to be surveyed by one of the Surveyors at the earliest opportunity thereafter.

4.4.2 Any damage in association with wastage over the allowable limit (including buckling, grooving, detachment or fracture), or extensive areas of wastage over the allowable limits, which affects or, in the opinion of the Surveyor, will affect the ship's structural, watertight or weathertight integrity, is to be promptly and thoroughly repaired. Areas to be considered include, (where fitted):

  • side shell frames, their end attachments or adjacent shell plating;
  • deck structure and deck plating;
  • bottom structure and bottom plating;
  • side structure and side plating;
  • inner bottom structure and inner bottom plating;
  • inner side structure and inner side plating;
  • watertight or oiltight bulkheads;
  • hatch covers or hatch coamings.

For locations where adequate repair facilities are not available, consideration may be given to allow the ship to proceed directly to a repair facility. This may require discharging stores/equipment and/or temporary repairs for the intended voyage.

4.4.3 Where repairs are to be carried out by a riding crew during a voyage, then these must be planned in advance. A complete repair procedure, including the extent of the proposed repair and the need for a Surveyor’s attendance during the voyage, is to be submitted reasonably in advance to the Surveyor for agreement. Failure to notify LR in advance of the repairs may result in the Class of the ship being specially considered by the Classification Committee. Where emergency repairs are effected immediately due to an extreme emergency circumstance, the repairs should be documented in the ship’s log and submitted thereafter to LR for use in determining further survey requirements.

4.4.4 When at any survey the Surveyor considers repairs to be immediately necessary, either as a result of damage, or wear and tear, they are to communicate their recommendations at once to the Owner, or his representative. When such recommendations are not complied with, immediate notification is to be given to the vessel’s Naval Classification Liaison Office by the Surveyor.

4.4.5 When at any survey it is found that any damage, defect, or breakdown (see Vol 1, Pt 1, Ch 2, 1.1 Framework of Classification 1.1.7) is of such a nature that it does not require immediate permanent repair, but is sufficiently serious to require rectification by a prescribed date in order to maintain Class, a suitable Condition of Class is to be imposed by the Surveyors and recommended for consideration. This condition may be designated as an operational defect, under the Owner’s control, but LR needs to be kept advised as to proposed actions. The technical impact of any deficiency on the operational needs of the ship must be considered by the Surveyor in liaison with the Owner before a decision is made with regard to corrective action.

4.4.6 If a ship which is Classed with LR is to leave harbour limits or protected waters under tow, the Owner is to advise LR of the circumstances prior to her departure.

4.4.7 If a ship which is Classed with LR is taken in tow whilst at sea, the Owner is to advise LR of the circumstances at the first practicable opportunity.

4.4.8 Plans and particulars of any proposed alterations (Mods. or A’s and A’s) to the approved scantlings and arrangements of the hull, machinery and engineering systems are to be submitted by the Owners or their representatives for approval by LR and such alterations are to be carried out to the satisfaction of LR’s Surveyors.

4.5 Existing ships – Periodical Surveys

4.5.1  Annual Surveys are to be held on all ships within three months, before or after each anniversary of the completion, commissioning or Special Survey. The date of the last Annual Survey will be recorded in the vessel’s Classification record. This survey may include optional requirements.

4.5.2  Intermediate Surveys are to be held on all ships instead of the third or fourth Annual Survey after completion, commissioning or Special Survey. The date of the last Intermediate Survey will be recorded in the vessel’s Classification record.

4.5.3 The Owner should notify LR whenever a ship can be examined in dry dock or on a slipway. An inspection of the underwater hull and its appendages is to be carried out not less than twice every six years. The maximum period between inspections of the hull and its appendages in dock or in-water is not to exceed three and a half years. Consideration may be given at the discretion of LR to any special circumstances justifying an extension of the maximum periods between inspections. A Docking Survey is to be carried out concurrently with the Special Survey. The required Docking Survey is considered to coincide with the Special Survey when held within the six months prior to the due date of the Special Survey. See Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.5. Where the Special Survey of the hull is carried out on a Continuous Survey basis, as given in Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.10, the survey in dry dock may be held at any time within the six-year cycle.

4.5.4 The date of the last Docking Survey will be recorded in the vessel’s Classification record.

4.5.5 Classification details and Survey requirements for In-water Surveys are given in Vol 1, Pt 1, Ch 2, 7 Classification of ship with *IWS notation and Vol 1, Pt 1, Ch 3, 4.3 In-water Surveys respectively. An In-water survey can be carried out in lieu of a Docking Survey for inspection of the underwater hull and appendages between the Docking Surveys that are to be carried out concurrently with the Special Survey. The date of the last In-water Survey will be recorded in the vessel’s Classification record, preceded with the notation *IWS.

4.5.6 All ships classed with LR are also to be subjected to Special Surveys. These Surveys become due at six-yearly intervals, the first one six years from the date of build or date of Special Survey for Classification as recorded in the vessel’s Classification record, and thereafter six years from the date recorded in the vessel’s Classification record, for the previous Special Survey. Consideration can be given, at the discretion of LR, to any exceptional circumstances justifying an extension of hull Classification beyond the sixth year. If an extension is agreed the next period of hull Classification will start from the due date of the Special Survey before the extension was granted. In this context ‘exceptional circumstances’ means unavailability of dry-docking facilities; repair facilities; essential materials; equipment or spare parts; delays incurred by action taken to avoid severe weather conditions; or urgent operational requirements.

4.5.7 Special Surveys may be commenced at the fifth Annual Survey or anniversary, as appropriate, after completion, commissioning, or previous Special Survey, and be progressed during the succeeding year with a view to completion by the due date of the Special Survey.

4.5.8 Special Surveys which are commenced prior to their due date are not to extend over a period greater than twelve months, except with the prior approval of LR.

4.5.9 Ships which have satisfactorily passed a Special Survey will have a record entered in the vessel’s Classification record indicating the date. Where the Special Survey is completed more than three months before the due date, the new record of Special Survey will be the final date of survey. In all other cases the date recorded will be the sixth anniversary.

4.5.10 At the request of an Owner, it may be agreed that the Special Survey of the hull can be carried out on a Continuous Survey basis, all compartments of the hull being opened for survey and testing, in rotation, with an interval of six years between consecutive examinations of each part. In general, approximately one sixth of the Special Survey is to be completed each year and all the requirements of the particular hull Special Survey must be completed at the end of the six-year cycle. Ships which have satisfactorily completed the cycle will have a record entered in the vessel’s Classification record indicating the date of completion which will not be later than six years from the last assigned date of Complete Survey of the hull.

4.5.11 If any examination during Continuous Survey reveals defects, further parts are to opened up and examined as considered necessary by the Surveyor, and the defects are to be made good to his satisfaction.

4.5.12 Alternative arrangements for survey periodicity will be considered by LR upon request. Requests from the Owner, at build or during service, need to be supported by adequate evidence of satisfactory performance before survey periodicity can be changed. These requests could be based upon Reliability Centred Maintenance or other forms of condition monitoring.

4.5.13 Machinery is to be submitted to the surveys detailed in Vol 1, Pt 1, Ch 3 Periodical Survey Regulations

4.5.14 Complete Surveys of machinery become due at six-yearly intervals, the first one six years from the date of build or date of first classification as recorded in the vessel’s Classification record, and thereafter six years from the date recorded in the vessel’s Classification record for the previous Complete Survey. Consideration can be given at the discretion of LR to any exceptional circumstances justifying an extension of machinery class to a maximum of three months beyond the sixth year. If an extension is agreed to, the next period of machinery class will start from the due date of Complete Survey of machinery before extension was granted. Surveys which are commenced prior to their due date are not to extend over a period greater than 12 months, except with the prior approval of LR. On satisfactory completion of a survey, an appropriate record will be made in the vessel’s Classification record. Where the complete survey is completed more than three months before the due date, the new date recorded will be the final date of survey. In all other cases the date recorded will be the sixth anniversary. See also Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.20.

4.5.15 Upon application by an Owner, LR may agree to the extension of the survey requirements for main propulsion machinery, which, by the nature of the ship’s normal service, does not attain the number of running hours recommended by the machinery manufacturer for major overhauls within the survey periods given inVol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.14.

4.5.16 When, at the request of an Owner, it has been agreed by LR that the Complete Survey of the machinery may be carried out on a Continuous Survey basis, the various items of machinery are to be opened for survey in rotation, so far as is practicable, to ensure that the interval between consecutive examinations of each item will not exceed six years. In general, approximately one sixth of the machinery is to be examined each year. A record indicating the date of satisfactory completion of the Continuous Survey cycle will be made in the vessel’s Classification record. See also Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.20.

4.5.17 Upon application by an Owner, LR may agree to an arrangement whereby, subject to certain conditions, some items of machinery may be examined by the qualified naval engineering personnel responsible to the Marine Engineer Officer of the ship, followed by a limited confirmatory survey and annual audit of maintenance and repairs records. Particulars of this arrangement may be obtained from the vessel’s Naval Classification Liaison Office. Where an approved planned maintenance scheme is in operation the confirmatory surveys of machinery may be held at annual intervals, at which time the records will be checked and the operation of the scheme verified. Particulars of this arrangement may also be obtained from the vessel's Naval Classification Liaison Office.

4.5.18 Where condition monitoring techniques are applied, LR, upon application by the Owner, will be prepared to amend applicable Periodical Survey requirements where details of the equipment are submitted and found satisfactory. Where machinery installations are accepted for this method of survey, it will be a requirement that an Annual Survey be held, at which time monitored records will be analysed and the machinery examined under working conditions. An acceptable lubricating oil trend analysis programme may be required as part of the condition monitoring procedures.

4.5.19 Where machinery installations include a ‘lifed item’ (an item of machinery, component or equipment necessary for the safety and reliability of propulsion, steering or other essential auxiliary engineering system) which is subject to an overhaul and/or ultimate life limitation, i.e. a period (expressed in operating hours or cycles and/or calendar time) at which the item is to be overhauled or scrapped, the life limitations are to be observed and take precedence over the periodicity of Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.14 and Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.16where the life limitation is less than the survey periodicity. Examples may include rolling bearing elements, gas turbines, turbochargers, flexible couplings and gear box elements. The manufacturer’s maintenance and service instructions are to be strictly observed. Where machinery installations include a ‘lifed item’ details will be noted in the classification records as a Memorandum (Machinery) record.

4.5.20 Where propulsion and auxiliary machinery is maintained using an approved ‘upkeep by exchange’ system, the Marine Engineer Officer is to maintain records of all exchanges carried out. At the first convenient opportunity after exchange, a running test on load is to be witnessed by a LR Surveyor (this may typically be the time of annual survey). Where prime movers are maintained by an ‘upkeep of exchange’ system, details will be noted in the classification records as a Memorandum (Machinery) record.

4.5.21 Boiler surveys, examination of steam pipes and Screwshaft Surveys are to be carried out as stated in Vol 1, Pt 1, Ch 3, 11 Boilers and Vol 1, Pt 1, Ch 3, 12 Steam pipes of these Regulations. On satisfactory completion, appropriate records will be made in the vessel’s Classification record.

4.6 Surveys for novel/complex systems, machinery and equipment

4.6.1 Where novel/complex systems, machinery and equipment have been accepted by LR and for which existing survey requirements are not considered to be suitable and sufficient, appropriate survey requirements are to be derived as part of the design approval process. In deriving these requirements LR will consider, but not be limited to, the following:
  1. Plan appraisal submissions;

  2. Risk Assessment documentation where required by the Rules;

  3. Equipment manufacturer recommendations;

  4. Relevant recognised National or International Standards.

4.7 Certificates

4.7.1 When survey reports have been received from the Surveyors and classification has been agreed by the Classification Executive, a Certificate of Classification may be issued by an authorised Surveyor. After approval by the Classification Committee, a Certificate of First Entry of Classification, signed by LR’s Chairman, or the Chairman of the Sub-Committee of Naval Classification Committee, may be issued to the Builders or Owners.

4.7.2 A Certificate of Class valid indefinitely subject to endorsement for Annual and Intermediate Surveys, as appropriate, will also be issued to the Owners and a certified copy placed on board. A new certificate will be issued when no further endorsement spaces remain.

4.7.3 LR’s Surveyors will issue provisional (interim) certificates, after survey, to enable a ship Classed with LR to proceed on voyage provided that it is in a satisfactory condition. Such certificates will embody the Surveyors’ recommendations for continuance of Class, and are subject to confirmation by LR.

4.8 Notice of surveys

4.8.1 It is the responsibility of the Owners to ensure that all surveys necessary for the maintenance of Class are carried out at the proper time.

4.8.2 Timely notice to an Owner about forthcoming surveys is available by means of access to LR’s Class Direct. The omission of such notice, however, does not absolve the Owner from their responsibility to comply with LR’s survey requirements.

4.8.3 The Owner will give timely notice of the availability of ships for survey. Should a ship not be available at the due time, the agreement for postponement of the survey should be sought from LR.

4.9 Withdrawal/Suspension of Class

4.9.1 When the Class of a ship, for which the Regulations as regards surveys on the hull, equipment and machinery have been complied with, is withdrawn by LR in consequence of a request from the Owner, the notation ‘Class withdrawn at Owner’s request’ (with date) will be assigned.

4.9.2 When the Regulations as regards surveys on the hull equipment and machinery have not been complied with and the ship is thereby not entitled to retain Class, the Class will be suspended or withdrawn after consultation with the Owner and a corresponding notation will be assigned. In order to maintain class, LR will require documentary evidence regarding the material state of the ship, its systems and equipment in terms of reports, photographs, measures or videos where the operational requirements exceed 12 months.

4.9.3 LR will consider requirements from the Owner to continue Class where operational requirements curtail surveys being held.

4.9.4 When in accordance with Vol 1, Pt 1, Ch 2, 4.4 Damages, repairs and alterations 4.4.4 and Vol 1, Pt 1, Ch 2, 4.4 Damages, repairs and alterations 4.4.5 a Condition of Class is imposed, this will be assigned a due date for completion and the ship’s Class will be subject to a suspension procedure if the condition of Class is not dealt with, or postponed by agreement, by the due date.

4.9.5 When it is found, from the reported condition of the hull or equipment or machinery of a ship, that an Owner has failed to comply with paragraphs Vol 1, Pt 1, Ch 2, 1.1 Framework of Classification 1.1.7, Vol 1, Pt 1, Ch 2, 4.4 Damages, repairs and alterations 4.4.1 or Vol 1, Pt 1, Ch 2, 4.4 Damages, repairs and alterations 4.4.7, the Class will be liable to be suspended or withdrawn, at the discretion of LR, and a corresponding notation assigned.

4.9.6 When any ship proceeds to sea with a draught greater than that approved, the Class will be liable to be withdrawn or suspended for the voyage.

4.9.7 In all instances of Class withdrawal or suspension, the assigned notation, with date of application, will appear in the vessel’s Classification record. In cases where Class has been suspended by LR and it becomes apparent that the Owners are no longer interested in retaining LR’s Class, the notation will be amended to withdrawn status. After Class withdrawn status has been established in the vessel’s Classification record for one year, it will be automatically amended to ‘Classed LR until’ (with date).

4.9.8 For reclassification and reinstatement of Class, see Vol 1, Pt 1, Ch 3, 4.3 In-water Surveys 4.3.2 and Vol 1, Pt 1, Ch 3, 4.3 In-water Surveys 4.3.3.

4.10 Survey of ships out of commission and/or laid-up

4.10.1 For ships assigned the notation ‘laid-up’, in order to maintain the ship in class, a general examination of the hull and machinery is to be carried out in lieu of the Annual Survey and an Underwater Examination (UWE) is to be carried out in lieu of the Special Survey, see;

4.10.2 In cases where the ship has been laid up or has been out of service for a considerable period because of a major repair or modification, the next due Special Survey shall be carried out and the period of class will start from the survey completion date. Where the ship has been laid up for a shorter period and with consideration of the extent of system operation during the laid-up period, a reduced periodical scope will be specially considered at the request of the Owners and at the discretion of LR.

4.11 Appeal from Surveyor’s recommendation

4.11.1 If the recommendations of the Surveyors are considered in any case to be unnecessary or unreasonable, appeal may be made to LR, who may direct a Special Examination to be held.

4.12 Ownership details

4.12.1 The Owner will ensure a member of the LR Group - Marine and Offshore division is promptly informed in writing of any change to their contact details and, in the event of a vessel/asset transfer or sale, is to supply details of the new Owner in writing. The new Owner is to promptly inform a member of the LR Group - Marine and Offshore division in writing of their contact details. If the new Owner fails to do so and if LR cannot verify the ownership record, then the class of that vessel/asset will be specially considered by the Classification Committee.
