Swedish Club case study following multiple explosions onboard after cargo fumigation

As part of its recently launched casebook series giving safety lessons learned from maritime incidents, the Swedish Club describes a case of multiple explosions onboard a bulk carrier caused by cargo fumigation. A bulk carrier had loaded yellow corn in all cargo holds up to the hatch coamings. After the loading was complete fumigation technicians came onboard and fumigated the cargo with fumitoxin pellets. As per the cargo documentation, the fumigation pellets were required to be applied subsurface.

In this instance, the technicians poured the pellets from flasks while walking on the hatch coamings or hatch covers. This work took a little more than an hour and, afterwards, all the cargo hatches were closed and the vessel sailed. A couple of hours later, an explosion occurred Continue reading “Swedish Club case study following multiple explosions onboard after cargo fumigation”

As part of its BSafe campaign, the Britannia P&I Club describes a fatality of an electrician from electrocution, while performing maintenance of the inert gas scrubber electrical system whilst onboard an oil tanker. The electrician had been working alone at the time. Before starting work in the morning on the day of the incident, the second engineer (2/E) held a Toolbox Talk to discuss the work planned for that day. The electrician mentioned he might work on the inert gas (IG) scrubber pump starter panel, but he did not specify the items to be completed, nor the timeframe for the work. No formal risk assessment, permit to work (PTW) or Lock Out/Tag Out (LOTO) procedure were completed, despite all being specifically required by the SMS.

Overtightening of locating bolts led to engine failure and grounding

The Swedish P&I Club has described in its Monthly Safety Scenario the case of a bulk carrier grounding caused by engine failure. Soon after departing port, a main engine slowdown alarm was triggered due to a loss of cooling water in the main engine. The Master ordered half head, but there was no response from the engine.

The bulk carrier in question loaded a cargo of soya beans in a North American port prior to travelling to Asia. When loading was completed, the vessel anchored to wait for a favourable tide. At midnight, the vessel departed and headed through the fairway. A pilot was onboard and a pilot briefing had been carried out with the Master.

Missing gasket leads to cargo hold flooding

The Swedish Club in its monthly safety bulletin describes a case history about the cargo hold flooding which was attributed to a tank missing a gasket to the manhole. Also, the bilge sensor was broken and heavily corroded, although it had been inspected a couple of days previously and found at the time to be in good condition.

When the container vessel arrived in port, it was instructed to anchor and wait until its berth was available. While the vessel was waiting for the berth, the Chief Officer decided to carry out a routine ballast tank inspection. The second completed a Permit for entry into the Continue reading “Missing gasket leads to cargo hold flooding”
