Section 2 Classification Survey during Construction
201. Classification survey during construction
For a submersible requiring classification survey during construction, the construction, materials, scantlings and workmanship of the structure, equipment and machinery are to be examined in detail in order to ascertain that they meet the appropriate requirements of this Rule.
202. Approval of plans
For a submersible requiring classification survey during construction, the plans and documents showing the details of the construction, materials, scantlings and particulars of the hull, equipment and machinery are to be submitted in accordance with as provided separately. The same applies al- so to the cases of any subsequent modifications to the approved drawings or documents.
203. Machinery installation
Main engine, shafting arrangement, boilers, pressure vessels, electrical equipment, piping arrange- ments and auxiliary machinery to be installed on a diving system intended for classification are to receive survey during construction. Shop trials are to be carried out on completion under the same condition as installed on diving system or a similar condition as far as practicable. Various tests on any special part amongst the automatic or remote control systems and measuring devices considered necessary by the Society may be requested at the manufacturing sites.

204. Workmanship
For classification survey of a submersible, the materials, workmanship and arrangements are to be surveyed under the supervision of the Society's Surveyor from the commencement of the work until the completion of the submersible. When the machinery is constructed under classification survey, this survey is related to the period from the commencement of the work until the final test under working conditions. Any item found not to be in accordance with the Rules or the approved plans, or any material, workmanship or arrangement found to be unsatisfactory are to be rectified.
205. Test
In the Classification Survey during Construction, hydrostatic, watertight and performance tests are to be carried out in accordance with the relevant part of the Rules. Also the control systems and measuring device after installation are to receive the necessary tests as deemed necessary by the Society.
