Test the solar container tank pressure

What are the testing requirements for gravity tanks?

9.2.1 The testing requirements for gravity tanks, defined as tanks subject to a vapour pressure not greater than 70 kN/m 2, and other boundaries required to be watertight or weathertight, are to be tested in accordance with this Section.

What are the testing requirements for a watertight tank?

9.4.1 Tanks which are intended to hold liquids, and which form part of the watertight subdivision of the ship, shall be tested for tightness and structural strength as indicated in Table 1.9.1 Testing requirements.

How is a tank shell tested?

Again all testing is carried out under the witness of the third party surveyor, and after successful completion the data plate is stamped and a test certificate is issued by the Class Society or competent authority. There are no specific requirements for checking the thickness of the tank shell.

What is a test pressure height?

In cases where a tank is designed for cargo densities greater than sea water and testing is with fresh water or sea water, the testing pressure height is to simulate the actual loading for those greater cargo densities as far as practicable., but the test pressure shall not exceed the maximum design internal pressure at the top of tank.

What are the testing procedures for watertight compartments for non-SOLAS ships?

9.2.4 Testing procedures for watertight compartments for non-SOLAS Ships are to be carried out in accordance with Pt 3, Ch 1, 9.5 Structural test procedures for non-SOLAS ships and SOLAS exempt/equivalent ships.

How often does a tank container need a hydrostatic test?

Each new tank container undergoes a hydrostatic test during construction. During service it is mandatory that each tank container undergoes testing every 2.5 years and 5 years. Failure to pass these tests results in tank containers no longer being approved for the carriage of hazardous products. The tanks must also comply with CSC.
