§153.361. Arrangements for removal of valves from venting systems having multiple relief valves.
46 C.F.R. § 153.361
A venting system having multiple relief valves may be arranged to allow the removal of a valve (for repair, as an example) provided the venting system:
Has valves that are interlocked, so that the removal of a valve does not reduce the venting system relieving capacity below the minimum relieving capacity required by § 153.358; and
Is arranged so that cargo vapor will not escape through the opening left after a valve has been removed.
