2.1.2 LR is authorized by the Government of Canada to carry out surveys or inspections in accordance with the '2000 Delegated Statutory Inspection Program' and with `The Classed Ship Inspection Regulations, 1988, of the Consolidated Regulations to the Canada Shipping Act'.

2.2 Existing ships

2.2.1  Classification of ships not built under survey. The requirements of the Committee for the classification of ships which have not been built under LR's survey are indicated in Pt 1, Ch 3, 19 Classification of ships not built under survey of the Rules for Ships. Special consideration will be given to ships transferring class to LR from another recognised Society.

2.2.2  Reclassification. The requirements of Pt 1, Ch 2, 3.3 Existing ships 3.3.2 of the Rules for Ships are to be complied with.

2.3 Damages, repairs and alterations

2.3.1 All repairs to hull, equipment and machinery which may be required in order that a ship may retain class, see Ch 2, 1.1 General 1.1.6, are to be carried out to the satisfaction of the LR Surveyors. When damages are sustained or where repairs are effected at a port or location where the services of an LR Surveyor are not available, LR is to be advised as soon as possible and the repairs are to be surveyed by LR at the earliest opportunity thereafter.

2.3.2 When at any survey the Surveyors consider 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 Committee by the Surveyors.

2.3.3 When at any survey it is found that any damage, defect or breakdown (see Ch 2, 1.1 General 1.1.5) is of such a nature that 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 to the Committee for consideration.

2.3.4 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.

2.3.5 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.

2.3.6 Plans and particulars of any proposed alterations to the approved scantlings and arrangements of hull, equipment, or machinery are to be submitted for approval, and such alterations are to be carried out to the satisfaction of LR’s Surveyors.

2.4 Existing ships - Periodical Surveys

2.4.1 Annual Surveys are to be held on all ships within three months, before or after each anniversary of the completion, commissioning or Special Survey in accordance with the requirements given in Ch 3, 2 Annual Surveys – Hull and machinery requirements.

2.4.2 Intermediate Surveys are to be held on all ships after the third Special Survey in accordance with the requirements of Ch 3, 3 Intermediate Surveys – Hull and machinery requirements. This survey may be held instead of the second or third Annual Survey.

2.4.3 The Owner should notify LR whenever a ship can be examined in dry-dock. Docking Surveys are to be carried out at intervals not exceeding five years in accordance with the requirements of Ch 3, 4 Docking Surveys – Hull and machinery requirements. Consideration may be given at the discretion of the Committee to any special circumstances justifying an extension of this interval. Before an extension can be agreed, a survey afloat of the underwater parts may be required at the discretion of the Committee.

2.4.4 A Hull Special Survey, is to be carried out on all ships at an interval not exceeding five years from the anniversary of the date of build or the previous Hull Special Survey, in accordance with the requirements of Ch 3, 5 Hull Special Survey – Hull requirements.

2.4.5 Postponement of the Hull Special Survey may be permitted by the Committee either completely or in part for a maximum period of 12 months, provided, by the due date:

  1. For complete postponement, a general examination of the ship including the requirements of an Annual Survey and an examination of at least the forward and aft side ballast tanks (port and starboard) is carried out to the Surveyor's satisfaction. An underwater examination may be required at the discretion of the Committee.

  2. For partial postponement, the items outstanding for completion of Hull Special Survey are generally examined to confirm satisfactory condition to the Surveyor's satisfaction.

  3. That thickness measurements are completed as far as practicable to the Surveyor's satisfaction.

On completion of the Hull Special Survey, the assigned date will be the last date the vessel was in dry dock for Special Survey or the Special Survey due date whichever is the later. The date assigned is not to exceed six years from the previous due date.

2.4.6 An Engine Special Survey is to be carried out on all ships as required by Pt 1, Ch 2, 3.5 Existing ships – Periodical Surveys 3.5.18 of the Rules for Ships.

In general, approximately 20 per cent of hull or machinery items is to be examined each year.

2.4.8 The CSM or ES date may be postponed for up to one year and will be assigned to harmonize with the Hull Special Survey date.

2.4.9 Machinery is to be surveyed as indicated in Pt 1, Ch 3, 11 Machinery surveys - General requirements of the Rules for Ships.

2.7 Withdrawal/Suspension of class

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

2.7.2 When the Regulations as regards surveys on the hull, equipment or machinery have not been complied with and the ship is thereby not entitled to retain class, the class will be suspended or withdrawn, at the discretion of the Committee, and a corresponding notation will be assigned.

2.7.5 When in accordance with Ch 2, 2.3 Damages, repairs and alterations 2.3.3 a condition of class is imposed, this will be assigned a due date for completion and the ship's class will be subject to suspension procedure if the condition of class is not dealt with, or postponed by agreement by the due date.

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.
