Question 1007 Deck General

The correct answer is D) The cargo piping system shall be fixed. For tank vessels carrying grade D or E cargo only, the cargo piping system is not required to be fixed. The regulations allow for the cargo piping system to be either fixed or portable. This is different from the requirements for higher grade cargoes, which do require the cargo piping system to be fixed. The other options are incorrect because they describe requirements that do apply to cargo piping systems, regardless of the cargo grade. Connections at bulkheads must be made so the plating does not form part of a flanged joint, flanged joints are required for pipe sizes over 2 inches, and piping through bunker spaces may be run through a pipe tunnel - these requirements apply to all cargo piping systems, not just those for grade D or E cargoes.
