Part 1 Chapter 2 Tests during construction 1/2.1 Compartments, bulkheads and accessories/sealing tests 12.1.1 Overview
SY/T 10032—2000
After all hatch covers and enclosed exits 11 and penetrations including pipe connections have been installed, all compartments and watertight bulkheads or sealed platforms shall be tested to prove that they are tight. For special test requirements, refer to Table 1/2.1. In certain areas with special approval, close-up visual inspection combined with non-destructive testing is acceptable in lieu of water testing. 1/2.1.2 Tank tightness test
The tank tightness test procedure shall be submitted to the Municipal Inspection for approval. Table 1/2.1 lists the commonly used test methods. When the requirements of Table 1/2.1 allow, unless the Surveyor has special test requirements, air pressure tests or combined air and hydrostatic pressure tests in accordance with approved test procedures are sufficient. When air pressure tests are used, all edge welds, installation connections, and penetrations including pipelines shall be inspected in accordance with approved test procedures and with leakage indicators before painting. The pressure difference of the air pressure test is usually 0.14kgf/cm (0.137bar, 2psi). Measures should be taken to prevent overpressure accidents during the tank tightness test. The air pressure drop test, that is, the test to check whether there is leakage by monitoring the pressure drop, cannot be used where hydrostatic pressure or air pressure/soap water test is required:
The tank tightness test must satisfy the on-site surveyor, and other test methods must also be identified by the surveyor. 1/2.1.3 Hydrostatic pressure test
Hydrostatic pressure test is required for unconventional cabin designs and structural types. Unless otherwise approved, cabins or devices that are subjected to external hydrostatic pressure loads during use must be subjected to hydrostatic pressure test. When hydrostatic pressure test is used, the test can be carried out before or after the launch of the buoy. If all welds, nodes and penetrations are inspected and approved by the surveyor before painting, the hydrostatic pressure test can be carried out after special painting. 1/2.1.4 Compartment water filling test
Water filling test is carried out while checking both sides of the joints. The water filling pressure shall not be less than 2.1kgf/em (2.06bar, 30pgi). 1/2.3 Compartment structure suitability test
In order to prove the suitability of the structure, a hydrostatic pressure test of a representative tank or buoyancy structure shall be carried out in relation to the approved design. Whether it is a new or unconventional buoy design, usually at least one compartment of each type is taken for hydrostatic pressure test. 1/2.5 Mooring system test
Each anchor leg and the components and safety devices connected to the buoy are inspected together to prove that the components, connectors and safety devices are properly installed.
The anchor leg includes the anchor chain, connectors such as unfastening ties, connecting rings and other components. These components must comply with the requirements of Sections 2/1.13 and 2/1.15 of the "Rules for the Construction and Classification of Offshore Mobile Drilling Units" of the relevant agency I. The tests must be carried out in the presence of the Surveyor. Each anchor leg must be subjected to an installation tension test in the presence of the Surveyor in accordance with the approved procedures. The tension test must be carried out in accordance with Sections 3/4.The requirements of Section 3 shall be met.
The mooring between the vessel and the SPM includes flexible cables or rigid mooring structures (rigid arm or flexible rigid hip arm). The size, material, specification and approved design of the cables shall be checked and confirmed. The components shall be checked for proper and safe assembly. The NDT test of the rigid mooring structure connected to the SPM buoy shall meet the requirements of the on-site surveyor. Tower mooring, designed as a fixed structure, usually consists of tubular components and is used to replace the floating structure and mooring legs. The inspection of this mooring structure shall be carried out in accordance with the requirements of the relevant agency "Regulations for the Construction and Classification of Offshore Installations Part 1 Structure". When piles and anchors are used with gravity caissons as the anchoring system for SPM, they shall be subjected to NIT tests in accordance with the relevant agency "Regulations for the Construction and Classification of Offshore Installations Part 1 Structure".
