The tank/piping material to be any "Y1" material.
Where lining of corrosion-resistant materials for steel tanks and
related piping systems, the elasticity of the lining should not be less
than that of the supporting boundary plating.
Unless constructed wholly of corrosion-resistant materials or fitted
with an approved lining, the plating thickness should take into
account the corrosivity of the cargo.
Slop tanks should not be adjacent to oil fuel tanks.
Provision should be made for suitable apparatus to detect leakage of
cargo into adjacent spaces.
Where inerting of cargo tanks is required, means should be
provided for monitoring ullage spaces containing a gas blanket to
ensure that the correct atmosphere is being maintained.
߰
Certain cargo requires that the vapour space within cargo tank to
have specially controlled atmosphere by filling the space with
moisture-free gas or vapour with a dewpoint of -40°C or below, and
maintaining that condition. |
