Section 2 Classification Survey during Construction

201. General

1. In the classification survey during construction, the hull and equipment, machinery, fire protection and detection, means of escape, fire extinction, electrical installation, stability and load lines are to be examined in detail in order to ascertain that they meet the requirements in the relevant Chapters. And the FRP ships are to be assigned load line as deemed necessary.

2. New installation of materials which contain asbestos is to be prohibited.

202. Plans and Documents submission

1. With respect to FRP ships intended for the classification survey during construction, the plans and documents listed in the following are, prior to the commencement of work, to be submitted for the approval by the Society.

(1) Hull

(A) List and data of raw materials[Incl. Material Safety Data Sheet (hereinafter referred to as "MSDS")]

(B) General arrangement

(C) Midship section

(D) Details of fore and aft construction, and stem and stern frame

(E) Propeller post and rudder (including materials and ship's speed)

(F) Construction profile (showing arrangement of watertight bulkheads, load line, sizes of brack-

ets and transverse sections of the ship at 0.1 Ã and 0.2 Ã from the ends of the ship)

(G) Deck plans (including the construction of hatchways, hatch beams, etc.)

(H) Construction of single bottoms and double bottoms

(I) Watertight and oiltight bulkheads (indicating the tank top and position for the top of over- flow pipes)

(J) Superstructures end bulkheads (including the construction of doors)

(K) Seatings of boilers, main engines, thrust bearings, plummer bearings, generators and other important auxiliary machinery (indicating output, height and weight of main engines and ar- rangement of holding-down bolts)

(L) Steering gear (indicating materials and details of structural arrangement for each parts)

(M) Laminating procedure and details of joints

(2) Machinery

Plans and documents in relation to the machinery specified in Pt 5, Ch 1, Sec 4 of Rules for

the Classification of Steel Ships.

(3) Other plans and documents deemed necessary by the Society

203.

Plans and Documents submission for Reference

1. Where intended for the classification survey during construction, the following plans or documents are to be submitted for reference, in addition to those for approval required in 202. :

(1) Specifications

(2) Certificates of FRP material tests specified in Ch 3. 302.

(3) Moulding procedure

(4) Calculation sheets and information with respect to structural strength

(5) Other plans and documents deemed necessary by the Society

204. Inspections during Construction

1. In the classification survey during construction, inspections are to be carried out covering all stages of the moulding 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 :

(1) When the tests of FRP specimens specified in Ch 3, 302. are carried out

(2) When designated by the Society during moulding work 【See Guidance】

(3) When the strength tests of FRP specified in Ch 3, 304. are carried out

(4) When the moulding are connected (e.g, shell to deck)

(5) When the materials or parts manufactured away from the site are applied to the FRP ships con- cerned

(6) When hydrostatic tests and watertight tests are carried out

(7) When sea trials are carried out

(8) When deemed necessary by the Society

3. With respect to the work in relation to machinery and equipment, the presence of the Surveyor is to be in accordance with the requirements in Pt 5, Ch 1, Sec 4 of Rules for the Classification of Steel Ships.

4. The stages of work for which the presence of the Surveyor is required in the preceding 2 may be modified in accordance with the actual status of facilities, technical abilities and quality control sys- tem at the works, except the case of the sea trials.
