The Australian Maritime Safety Authority has issued a marine notice to inform all shipowners, operators, masters and crew of the hazards when working with high-pressure fire-fighting systems and the safeguards that may be implemented to prevent injury.

A seafarer was severely injured when he attempted to carry out maintenance work on part of a 13 bar high-pressure fire-fighting system on a fire-fighting tug. Before the incident, the seafarers had conducted maintenance work on the manifold on the other side of the vessel without any accidents. The assumption was based on the fact that the system was not pressurised.

During his maintenance routine, the seafarer tried to remove the Continue reading “AMSA warns of safety measures for fire-fighting systems”

The impact of IMSBC Code changes on coal cargoes

Posted on by News Hound
The classification of coal has been amended so that it will be treated as both Group A and B, unless otherwise tested.
The classification of coal has been amended so that it will be treated as both Group A and B, unless otherwise tested.

On 1 January 2019 amendments to the IMSBC Code will apply. In an article to Gard Club, Penelope Cooke of Brookes Bell LLP, explains the impact of these changes on vessels carrying coal cargoes.

The amendments to the IMSBC Code regard the criteria under which coal cargoes are considered Group A, namely liable to liquefy, in addition to Group B chemical hazards which apply to all coal cargoes. Thus, coal cargoes may need the same TML and moisture certification as other Group A cargoes, such as concentrates, nickel ore and iron ore fines.

Two crew members, who were inside the deck slewing crane’s cabin, were seriously injured.

Transport Malta’s MSIU has published its investigation report on the slewing deck crane failure onboard the Maltese-flagged product tanker ‘Bozdag’, while the ship was in the port of Tallinn on 28 November 2017.

The report revealed that the dynamic loading and the sudden halt of the free falling loads were two major contributing factors to the failure of the deck slewing crane.

Details of the incident

A regular, five-yearly compulsory test on the ship’s deck slewing crane was planned for 28 November 2017. Given that the safe working Continue reading “Dynamic loading contributed to deck slewing crane failure says report”

The London P&I Club together with Paul Willis Senior Associate at Hawkins have published a loss prevention guide regarding the risks of carrying coal cargoes. The report gives special consideration to the issues surrounding gas monitoring and ventilation.

The guide mentions that the management of coal cargoes and the proper use of gas detection equipment are vital to prevent coal fire claims. It also details the basic requirements regarding the installation, use and maintenance of gas detection devices and the different types of sensors involved in their operation.

According to the report, the gas detection and monitoring equipment on board ships can vary from large units such as the Riken Keiki RX–515 to smaller more portable types such as the BW Gas Alert Max XT II.

The report team found that the risk clearly depends on the level of congestion.
The report team found that the risk clearly depends on the level of congestion.

A new Volvo Ocean Race (VOR)-commissioned report has examined ocean racing at night in areas of high vessel traffic density to establish possible steps to mitigate risk following the death of a fisherman during the race.

The independent Volvo High Traffic Density Report follows the collision between Vestas 11th Hour Racing and a fishing vessel this January, in the final stages of the leg into Hong Kong during the most recent edition of the race. The crews recounted that virtually all the vessels had some form of lighting and exhibited AIS. The fishing vessels were either stationary or travelling at slow speeds of 3-6 knots and they did not form an impenetrable barrier.

Recommendations made in the report included use of Continue reading “Recommendations on reducing yacht racing risks released”

IMO has adopted a plan to address the issue of marine plastic

Posted on by News Hound
Dumping plastics into the sea is already prohibited under MARPOL regulations, which also oblige governments to ensure adequate port reception facilities to receive ship waste.
Dumping plastics into the sea is already prohibited under MARPOL regulations, which also oblige governments to ensure adequate port reception facilities to receive ship waste.

The IMO has pledged to address the significant problem posed by plastics to the marine environment, with the adoption of an action plan which aims to enhance existing regulations and introduce new supporting measures to reduce marine plastic litter from ships.

The plan was adopted on October 26 by IMO’s Marine Environment Protection Committee (MEPC).

Dumping plastics into the sea is already prohibited under MARPOL regulations, which also oblige governments to ensure adequate port reception facilities to receive ship waste. Under the London Convention and Protocol on the dumping of wastes at sea, only permitted materials can be dumped and this waste – such as from dredging – has to be fully assessed to ensure it does not contain harmful materials like plastics.

However, studies demonstrate that despite the existing regulatory framework to prevent marine plastic litter from ships, discharges into the sea continue to occur. Recognising that more Continue reading “IMO has adopted a plan to address the issue of marine plastic”

Preventing coal cargo from self-heating

Posted on by News Hound
The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane).
The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane).

London P&I Club has analysed the problems associated with the transportation of coal in bulk, such as self-heating and flammable gas (i.e. methane) release. Self-heating can lead to fires and the production of carbon monoxide (CO), whilst methane release can lead to an explosive atmosphere being generated in the hold.

Self-heating normally occurs in localised hot spots within a bulk cargo, and temperature measurements are unlikely to identify problems. However, when coal self-heats it produces CO, so measuring the concentration of CO is the most effective method to identify a self-heating cargo.

The atmosphere in each cargo hold should be monitored, at least on a daily basis, for CO, hydrogen sulphide (H2 S), oxygen (O2) and flammable gas (LEL-methane). If the holds are being ventilated, then ventilation should be stopped at least Continue reading “Preventing coal cargo from self-heating”

The UK P&I Club has published helpful guidance to ensure safe bunkering operations. The Club said that bunkering operations are routine and critical, high risk operations which require to be carefully planned and performed.

Causes of bunker spills

Although the most of the bunker transfers are carried out without incident, very occasionally, things can and do go wrong. The UK Club notes that only a minority of cases do bunker spills occur because of failure of the hoses or pipelines, while the majority of spills result from a tank overflowing.

But these are not the only causes. Common causes of bunker spills can be summarised as follows:

– Improper set up of pipeline system valves: Potentially causing either overpressure, or flow of bunkers to an unintended location;
– Insufficient monitoring of tank levels during bunkering: All tanks, not only those Continue reading “How to conduct a safe bunkering operation”

Loss of propulsion led FRPD 309 to collide with loaded barge

The FRPD 309 sustained damage to the shell plating and forepeak tank forward of the collision bulkhead. In addition, the port anchor was disconnected from its housing and became wedged in the Evco 60's hull
The FRPD 309 sustained damage to the shell plating and forepeak tank forward of the collision bulkhead. In addition, the port anchor was disconnected from its housing and became wedged in the Evco 60’s hull

The Transportation Safety Board of Canada released its investigation report into the collision of the dredger FRPD 309 with the loaded barge Evco 60, on 5 December 2017, in the Fraser River.

The incident

On 04 December 2017, the dredger FRPD 309 departed a shipyard in Delta, BC, to begin dredging in the Fraser River. The vessel is a conventional trailing arm suction dredger, with the bridge and accommodation located forward and machinery space located aft. Before departure, the crew had carried out pre-departure checks, a safety meeting, and emergency drills.

After arriving at the dredging location, the vessel started dredging sand and sediment from the river bed into the hopper using the 2 trailing arms and a dredging pump. When the hopper was filled, the sand and sediment was pumped ashore via a pipeline. The master left the bridge, handing over the command of the vessel to the officer of the watch (OOW). Two engineers, 2 deckhands, and a pipe operator were also on duty.

As the vessel was turning and the pipe operator was raising the trailing arms to the deck level, the vessel experienced Continue reading “Loss of propulsion led FRPD 309 to collide with loaded barge”
