At the positions for monitoring the cargo loading and discharging operations, the cargo lines are to be fitted with pressure gauges with a red mark denoting the maximum permissible working pressure.
Steam lines to the individual heating coils of the cargo tanks are to be fitted with screw-down non-return valves.
Means of testing the condensate for ingress of oil are to be fitted before the stop valves in the heating coil outlets.
The condensate from the heating system is to be returned to the feed water system via observation tanks.
Condensate observation tanks are to be arranged and equipped such that cargo residues in the condensate will not constitute a hazard in engine room or other gas safe spaces.
