Section 2 Classification Survey during Construction

201. General

In the classification survey during construction, the construction, materials, scantlings, and workman- ship of the hull, equipment and machinery are to be examined in detail in order to ascertain that they meet the relevant requirements of the Rules, and for barges which are required to be marked with load lines, the load lines are to be assigned.

202. Submission of plans and documents

(C) Hydrostatic curves

(D) Plans showing the height of timber deck cargo and the arrangements of lashing and fixing, if the timber load lines are to be assigned

(7) Particulars of machinery

(8) Calculation sheets of torsional vibration for generator shaftings(in case where the maximum con- tinuous output of engine is more than 100 kW)

(9) Calculation sheets of battery capacity for navigation light

Submission of other plans and documents than specified in Par 1 and 2 may be required where deemed necessary by the Society.

Presence of surveyor

1. In the classification survey during construction, inspections are to be carried out covering a1l stages of the work from its commencement until its completion.

2. The presence of the Surveyor is required at the following stages of the work in relation to hull and equipment.

(1) Material test.

(2) When designated by the Society during shop work or sub-assembly.

(3) When each block is assembled.

(4) When hydrostatic test, watertight test, etc. are carried out.

(5) When hull is completed.

3. The presence of the Surveyor is required at the following stages of the work in relation to machinery.

(1) When the tests for boilers and pressure vessels to belong to Group I or Group II are carried out.

(2) When the tests for the valves, cocks and distance pieces attached to the shell plating are carried

out.

(3) When the tests for the explosion-proof type electrical equipments are carried out.

(4) When machinery is installed on the barge.

(5) When the tests and trials on board are carried out.

(6) When the popping test and accumulation test for safety valve of boiler are carried out.

(7) When the test for machinery of special type are carried out.

4. The requirements specified in Par 2 and 3 may be modified having regard to the actual status of facilities, technical abilities and quality control at the works.

5. Submission of the data of the tests carried out in the works as specified in Ch 20, 1601. 2, 4

and 5 may be required where deemed necessary by the Surveyor.

204. Sea trials

For barges having unconventional construction or special navigation system, sea trials will be quired where deemed necessary by the Society.
