在船舶建造的新船建造阶段，通常会开展以下活动：

1. 入级申请：船级社与造船厂签订合同，其中详细规定了商定的工作范围，以及造船厂需按照船级社规则和规范建造船舶，并计划在交付时使其入级的协议。

2. 图纸审核：造船厂委托的设计方提交的图纸和文件将由船级社的审图工程师进行审核。

3. 建造检验：新船（NC）验船师将在船舶建造的整个期间进行检验，以核实船舶建造是否遵循已批准的图纸，并且依据已批准的检验与试验计划（ITP），参加在造船厂设施内或船上进行的各项试验。

4. 参加测试与试航：新船验船师需见证各类测试（例如，管道的液压试验、泄漏测试、液舱的结构测试、设备及相关专业的调试测试）。新船验船师还会参加船舶的海上试航。

5. 证书签发：在各项检验圆满完成后，法国船级社（BV）将签发船级证书，并且在得到船旗国主管机关授权的情况下，代表船旗国主管机关签发法定证书（船级社验船师也会进行诸如《国际海上人命安全公约》（SOLAS）、《国际防止船舶造成污染公约》（MARPOL）、《国际载重线公约》、吨位丈量以及《国际安全管理规则》/《国际船舶和港口设施保安规则》（ISM/ISPS）等法定检验）。

   

CLASSIFICATION PROCESS FOR NEW CONSTRUCTION

These are the activities that are commonly carried out during the new construction stage of shipbuilding:

1. Request for Classification – Contract between the classification society and the shipyard is signed, which details the scope of work agreed upon and an agreement that the shipyard would construct the ship to the Classification Rules and Regulations, with the intention to class it upon delivery.

2. Plan Review – Drawings and documents submitted by the designer appointed by the shipyard would be reviewed by the classification society’s plan approval engineers.

3. Construction Survey – The NC surveyor will conduct a survey during the whole period of the ship’s construction, to verify that it follows the approved drawings, and also attend tests performed at the shipyard’s facilities or onboard the vessel based on the approved ITP (Inspection and Test Plan).

4. Attending Testing and Trial – Various tests are witnessed by the NC surveyor (e.g. HT of pipes, leak tests, structural test of tanks, commissioning tests of
equipment and related disciplines). The NC surveyor would also attend the sea trial.

5. Issuing of Certificate – Upon the satisfactory completion of surveys, BV will issue classification certificates and also statutory certificates on behalf of the Flag Administration (When authorised by the Flag Administration, a class surveyor will also conduct statutory surveys such as SOLAS, MARPOL, LOADLINE, TONNAGE AND ISM/ISPS).
