Section E Safety and Security Management

E.19 It is Strongly Preferred that Anemometer display / monitoring repeater with a recorder (paper / digital) is available in the Cargo Control Room (CCR) and designed to be capable of setting a minimum of two desired alarms limits. This alarm should sound an audible and visual alarm in the Cargo Control Room (CCR) and on deck if the set limits are exceeded.

Section H Cargo and Ballast Systems

H.27 It is Strongly Preferred that vessels are fitted in their Cargo Control Room with a device capable of monitoring and recording the load / discharge manifold pressure.

H.29 Vessels MUST have fixed cargo tanks pressure monitoring equipment fitted on board with display unit installed in the cargo control room and designed to have within manufacturers set alarms (High and low) including additional setting of a minimum two desired alarms limits. This alarm should sound an audible and visual alarm in the CCR if the set limits are exceeded.

H.30 It is Strongly Preferred that vessels are fitted with IG tank pressure monitors on the bridge.

SELMA Tank Protector fully complies with and exceeds ExxonMobil MESQAC E.19, H.27, H.28 and H.29.
