The IMO’s Sub-Committee on Ship Systems and Equipment (SSE) has finalized prohibition of perfluoro-octane sulfonic acid from fire-fighting systems on board ships.

This prohibition will protect the crew against exposure to dangerous substances that are used in fire-fighting systems and will minimize the negative consequences on the environment.

The International Maritime Organization’s (IMO) sub-committee on ship systems and equipment (SSE) met for the 8th session from 28 February to 4 March. It is important Continue reading “IMO agrees to ban perfluoro-octane sulfonic acid”

AMSA has launched a new construction barge safety campaign focused on the importance of regularly reviewing risks as part of the safety management system to protect lives on these types of vessels.

All domestic commercial vessels are defined as workplaces in Work Health and Safety (WHS) laws. This includes construction barges which must meet the risk assessment requirements of state and territory WHS regulations, as well as the risk assessment requirements under the National Law administered by AMSA.

“These barges undertake different and high-risk activities daily Continue reading “AMSA launches campaign to improve construction barge safety”

On 19 September 2021, a fire broke out in the auxiliary engine room on board the Finland registered roll-on/roll-off cargo ship Finnmaster while departing Hull. In an attempt to extinguish the fire, the ship’s crew activated the machinery space’s fixed CO2 fire extinguishing system pilot hoses, but only half of the system’s gas cylinders opened. The initial investigation identified that one of the CO2 system pilot hoses was blocked due to a manufacturing defect. Several coupling leaks were also found in the pilot lines.
