ON SHIPS CARRYING FLAMMABLE OR TOXIC PRODUCTS OR BOTH, A WATER SPRAY SYSTEM FOR COOLING, FIRE PREVENTION AND CREW PROTECTION SHOULD BE INSTALLED TO COVER EXPOSED CARGO TANK DOMES AND ANY EXPOSED PARTS OF CARGO TANKS. PSCO OBSERVED INSUFFICIENT PRESSURE TO COVER TANK DOMES 1 AND 2. 74SOLAS(20) VII/13.1 IGC (93) 11.3

THE CONTROL SYSTEM FOR ALL REQUIRED EMERGENCY SHUTDOWN VALUES SHOULD BE SO ARRANGED THAT ALL SUCH VALUES MAY BE OPERATED BY SINGLE CONTROLS SITUATED IN AT LEAST TWO REMOTE LOCATIONS ON THE SHIP. ONE OF THESE LOCATIONS SHOULD BE THE CONTROL POSITION REQUIRED BY 13.1.3 OR CARGO CONTROL ROOM. THE CONTROL SYSTEM SHOULD ALSO BE PROVIDED WITH FUSIBLE ELEMENTS DESIGNED TO MELT AT TEMPERATURES BETWEEN 98°C AND 104°C WHICH WILL CAUSE THE EMERGENCY SHUTDOWN VALVES TO CLOSE IN THE EVENT OF FIRE. PSCO OBSERVED THE FUSIBLE ELEMENTS PAINTED ON THE #1 AND #2 CARGO TANK LIQUID CARGO FILL LINES AND ON THE PORT SIDE MANIFOLD. 74 SOLAS (20) VII/13.1 IGC (93) 5.6.4

THE VAPOR SPACE OF EACH CARGO TANK SHOULD BE PROVIDED WITH A PRESSURE GAUGE WHICH SHOULD INCORPORATE AN INDICATOR IN THE CONTROL POSITION REQUIRED BY 13.1.3. THE ALARMS SHOULD BE ACTIVATED BEFORE THE SET PRESSURES ARE REACHED. PSCO OBSERVED THE PRESSURE INPUT TO THE SENSOR ON THE #2 CARGO TANK DISCONNECTED. SHIP’S CREW PERFORMED MAINTENANCE AND RECTIFIED. 74SOLAS(20) VII/13.1 IGC (93) 13.4.1

Each Flammable gas detection system must have an audible and visual alarm for power failure and loss of gas sampling flow. PSCO observed the fixed gas detection power failure alarm inoperable. 46 CFR 154.1350(f)

0999-Other (safety in general)Gas detection equipment should be so designed that it may readily be tested. Testing & calibration should be carried out at regular intervals. PSCO note, during calibration of gas detection equipment, that the system was out of calibration.-IGC 13.6.6. a-prior to cargo

1099(Other alarm signals) Each cargo tank should be fitted with a high level alarm operating independently of other liquid level indicators and giving an audible and visual warning when activated. Crew was unable to demonstrate operation of the sensor and vsl was unable to provide testing procedures for the high level alarm. IGC 13.3.1 - 50a
