2.1.1 The ship is to be arranged and prepared for examination as required by Pt 1, Ch 3, 2.2 Examination and testing for ships which are to be subjected to Annual Surveys as set out in Ch 2,3.5.1 or Pt 1, Ch 3, 2.3 Examination and testing for ships which are subjected to Annual Surveys as set out in Ch 2,3.5.2 as applicable.

2.2.1 The Surveyor is to be satisfied as to the efficient condition of the following:

1. Hatchways on freeboard and superstructure decks, ventilator and air pipe coamings, exposed casings, skylights, deck-houses and companionways, superstructure bulkheads, side scuttles and deadlights, together with all closing appliances.

2. Means of ensuring weathertightness of steel hatch covers by hose test if deemed necessary.

3. Scuppers and sanitary discharges with valves.

4. Guard rails and bulwarks, freeing ports, gangways and life-lines.

5. Freeboard marks.

6. Steering arrangements.

7. Vent piping, including that of inert gas installations, where applicable, within the cargo tank area, together with associated flame arresters and pressure/vacuum valves.

8. Cargo and bunker deck piping of tankers.

2.2.2 On tankers of Type G, C and N, see Pt 4, Ch 4 General Requirements For Tankers Carrying Dangerous Liquids in Bulk, Pt 4, Ch 5 Tankers of Type G and Pt 4, Ch 6 Tankers of Types C and N, when submitted for the survey required by Pt 1, Ch 2, 3.5 Existing ships – Periodical Surveys 3.5.7, pump-rooms and the electrical installation are also to be inspected, including verification of:

1. The efficiency of any safe type equipment fitted.

2. The insulation resistance.

3. Tests carried out to demonstrate the effectiveness of earth bonding straps, where fitted.

Inert gas installations are to be examined in accordance with Pt 1, Ch 3, 16 Inert gas systems.

2.3.1 Surveyors are to examine the ship afloat in light condition internally and externally, as far as necessary in order to satisfy themselves as to the efficient condition of the hull structure.

2.3.2 Should examination afloat give rise to doubts as to the condition of the underwater structure or of tanks and cofferdam spaces, it may be necessary for Surveyors to require the ship to be dry-docked or placed on a slipway for a more detailed inspection.

2.3.3 Where the ship is placed in dry dock or on a slipway, Surveyors are to examine the shell plating, the sternframe, rudder(s), etc. and attention is to be given to those underwater parts of the ship particularly liable to deterioration due to excessive corrosion or to damage by contact with other vessels, quay walls or from causes such as chafing, touching or lying on the ground and to any undue unfairness of bottom plating especially in transversely framed ships.

2.3.4 Surveyors are to satisfy themselves as to the efficient condition of the following, where applicable:

1. Hatchways with beams and covers, deck-houses and companionways together with any closing appliances.

2. Scuppers and sanitary discharges so far as practicable, bulwarks and guard rails.

2.3.5 Surveyors are to examine the steering arrangements. The various parts of the auxiliary steering gear are to be assembled to ascertain that the gear is in good and workable condition. Auxiliary steering gear of the mechanically driven type is to be examined and tested to demonstrate that, if the power for the main steering gear fails, the auxiliary gear can be put into operation immediately.

2.3.6 Surveyors are to examine and test bow rudder installations when they are an essential part of the steering arrangement. Opening up the gear may be required if deemed necessary by Surveyors in view of the condition or the testing of the gear.

2.3.7 When chain cables are ranged, the anchors and cables are to be examined by the Surveyors.

2.3.8 Surveyors are to satisfy themselves as to the efficient condition of the fire protection, detection and extinguishing arrangements so far as applicable.
