A cargo tank Which might be bodily altered to conform to another cargo tank specification should have the needed physical alterations to transform from just one specification to another Evidently indicated to the variable specification plate.

implies a self-closing prevent valve designed so the self-saved energy supply is located Within the cargo tank or cargo tank sump, or throughout the welded flange, along with the valve seat is located in the cargo tank or within just one particular inch from the exterior face on the welded flange or sump of the cargo tank.

The pressure relief units ought to open up quickly at a stress not below the MAWP and become absolutely open up in a pressure equal to 110% in the MAWP. These units have to, immediately after discharge, shut in a pressure not reduce than 10% under the strain at which discharge commences and have to keep on being shut in the slightest degree lessen pressures. The pressure aid equipment must be of the sort that will resist dynamic forces like surge.
