Standard Club has published an invaluable bulletin about mega box ships

As the size of mega box ships has steadily increased, so has the level of difficulty in handling casualties involving them. A special 32 page edition of the Standard Club bulletin has been published and looks at the different legal, technical and practical considerations.

Ultra large container ships, or mega box ships as they are commonly called, can have a carrying capacity in excess of 20,000 TEU (twenty foot equivalent units) and are frequently in excess of 14,500 TEU. This can have a considerable impact in the event of a casualty. In particular, the global shipping and insurance markets have expressed concern regarding the firefighting capability of these ships, which has not necessarily kept pace with their increasing size. It can be extremely difficult to find suitable ports of refuge to accommodate these ships and which have infrastructure capable of handling the number of containers on board.

USCG publishes a safety alert after three confined space fatalities on a MODU

Posted on by News Hound
Seven of the crew onboard were involved in the dewatering operation and this incident. All were experienced mariners, but lacked MODU experience.
Seven of the crew onboard were involved in the dewatering operation and this incident. All were experienced mariners, but lacked MODU experience.

The US Coast Guard (USCG) has issued an important Safety Alert on the dangers of confined space entry following a recent incident where three people were asphyxiated in a confined space on a drilling rig (MODU).

The USCG says that studies show that people often miss the obvious clues while working under enhanced stress and because their focus is on another activity. Several sources indicate that over 50% of those who perish in enclosed and confined spaces accidents do so while trying to assist and rescue their co-workers.

Ten crewmembers were on board the MODU preparing it for a heavy lift transport to an overseas ship breaking facility. They were successful in dewatering three of the MODU’s four legs.

Yet, the de-ballasting system was inoperable in the fourth leg because piping and valves had been previously removed. To continue pumping, the crew rigged a portable diesel engine driven pump to discharge the tanks.

New technology aims to reduce underwater radiated noise generated by ships’ propeller cavitation

Posted on by News Hound
While PressurePores are suitable for all types of vessel, they are particularly suitable for naval vessels, fishing fleets, offshore vessels and cruise ships operating in sensitive environments.
While PressurePores are suitable for all types of vessel, they are particularly suitable for naval vessels, fishing fleets, offshore vessels and cruise ships operating in sensitive environments.

A new technology aimed at reducing the underwater radiated noise (URN) generated by ships’ propeller cavitation has been developed by Strathclyde University and Oscar Propulsion.

The patented Oscar PressurePores system reduces propeller tip vortex cavitation by applying a small number of strategically bored holes in the propeller blades.

The addition of these pressure-relieving holes now allows ships to operate with a more silent propeller with a minimum of compromise on its efficiency or having to slow steam. Reducing cavitation also reduces its associated erosive effect.

IG Clubs continue to implement survey triggers for tankers carrying HFO

Posted on by News Hound
If a vessel continues to carry HFO as cargo over a period of successive years, the Club is not obliged to carry out a survey every year.
If a vessel continues to carry HFO as cargo over a period of successive years, the Club is not obliged to carry out a survey every year.

As part of the industry’s efforts to ensure higher ship standards, the International Group of P&I Clubs (IG Clubs) continues to implement survey triggers for seagoing vessels of 10 years of age or more carrying HFO, the American P&I Club has reminded the industry in a bulletin.

As a consequence, all sea-going vessels aged 10 years or more which have carried heavy HFO as cargo within the previous 12 months will be subject to condition survey, unless:
– the vessel has undergone a P&I club condition survey during the previous 12 months; or
– the vessel has undergone a Special Survey during the previous 6 months; or
– the vessel has a valid Condition Assessment Program (CAP) rating of 1 or 2 with a classification society having membership in the International Association of Classification Societies (IACS).
– HFO is defined as residual fuel with a kinematic viscosity of 380 centipoises when measured at 50 degrees Celsius by the ISO 3104 test method.

During the meeting of the IMO Sub-Committee, a correspondence group was established.

The IMO Sub-Committee on Ship Systems and Equipment held its 6th Session from 4 to 8 March 2019. The meeting focused on improvements in ventilation conditions of survival craft that will be achieved by finalising draft amendments to the LSA Code on ventilation requirements for survival craft and draft amendments to the ‘Revised recommendation on testing of life-saving appliances’.

Mainly, the Sub-Committee discussed the draft amendments to the LSA Code, relating to ventilation requirements of totally enclosed lifeboats.

In the meantime, the meeting made progress in developing draft amendments to the revised recommendation on testing of life-saving appliances regarding the ventilation of survival craft, aiming to ensure a habitable environment is maintained in such survival craft.

The Transportation Safety Board of Canada (TSB) has published an investigation report on the sinking of the fishing vessel ‘Western Commander’ off Triple Islands, Dixon Entrance, British Columbia, in April 2018. The report highlighted issues related to safe loading practices and proper risk identification.

In April 2018, the vessel was under contract to sea urchin buyers to transport urchins for 11 different harvesters. From 4 April to the morning of 6 April, the vessel remained at anchor in Parry Passage due to inclement weather.

Around 0900 on 9 April, the mate, who was on watch, noticed that the vessel was not fully returning upright when it was heeled over by the swell. Water was coming over the port railing and remaining on deck, and the vessel developed a port list. At some point, water had entered the port forward fish hold. In an attempt to Continue reading “Safe loading practices highlighted in fishing vessel sinking”

The US Coast Guard has published its Findings of Concern with essential information it wishes to share about unsafe conditions that investigators have identified as causal factors such as vessel stability in a casualty that could contribute to future incidents. The Findings of Concern follow the sinking of a fishing vessel in February 2017.

In February 2017, immediately after 27 days of cod fishing, a 98-foot commercial fishing vessel carrying 200 crab pots with a crew of six departed Dutch Harbor, Alaska, and proceeded towards St. Paul Island to drop off bait with the intent to transit to the Opilio crab fishing grounds.

The vessel got underway despite multiple National Weather Service (NWS) marine forecasts indicating areas of freezing spray throughout the vessel’s planned route.

The US National Transportation Safety Board (NTSB) issued an investigation report on the sinking of the towing vessel ‘Ricky Robinson’ on the Lower Mississippi River, in December 2017, which caused death of the two crewmen onboard, oil discharge and significant damage of the vessel.

On 8 December 2017, about 11:26 local time, the Ricky Robinson capsized and sank on the Lower Mississippi River at mile 732.8 near Memphis, Tennessee, with two crewmembers on board, after the towing vessel began taking on water.

The pilot made a distress call just before the sinking; neither crewmember was found during the search and rescue operations that followed.

When the vessel was recovered 9 days later, the deckhand’s body was discovered inside the wreckage; the pilot is Continue reading “Unsecured deck hatches led to sinking of Ricky Robinson”

Leaking lube oil causes engine room fire on towing vessel

The speed of which the fire grew to encompass the engine room and the location of primary fire equipment within that same space together eliminated the opportunity for the crew to effectively fight the fire.

The NTSB issued an investigation report on the engine room fire and explosion onboard the towing vessel ‘J.W. Herron’ on Big Bayou Canot near Mobile, Alabama in December 2017. The report identified leaking lube oil from a propulsion diesel engine hose or tubing fitting that was ignited off an exposed hot engine surface, as the key cause of the accident.

About 1340 local time on 13 December 2017, the towing vessel J.W. Herron was shifting barges on Big Bayou Canot near Twelvemile Island, approximately 8 miles north of Mobile, Alabama, when a fire began in the lower engine room and quickly spread.

After the crew of three partially secured the engines and fuel supply, heavy smoke and fire prevented them from Continue reading “Leaking lube oil causes engine room fire on towing vessel”

Fire caused by moving cargo

One of the containers came loose and hit one of the flat racks with jerry cans.
One of the containers came loose and hit one of the flat racks with jerry cans.

The Swedish Club has released details about a cargo fire caused by moving cargo due to inclement weather conditions. The case has highlighted the importance of detailed planning and discussions among Master, Chief Officer, technical manager or charterer, when it is about critical cargo operations.

The RoRo vessel was underway and expected to sail through heavy weather with up to Beaufort scale 10 winds and eight metre high waves. The cargo onboard consisted mainly of vehicles, containers and jerry cans with fuel on flat racks.

Before loading, the Chief Officer went ashore to inspect the cargo. He inspected the jerry cans that were secured with quick lashings through the handles of each row and secured to bars on the flat racks.

He was concerned that the jerry cans were placed on flat racks and not in containers, as there were no walls around the racks to protect the jerry cans. The flat racks and containers were Continue reading “Fire caused by moving cargo”

Hull damage caused to the Celtica Hav
Hull damage caused to the Celtica Hav

At 1438 on 27 March 2018, the Bahamas registered general cargo vessel Celtica Hav grounded on a stone training wall in the approach channel to the River Neath, Wales.

The vessel had a harbour pilot on board at the time who had control of the steering and speed. Celtica Hav was quickly re-floated and manoeuvred clear of the training wall.

It suffered extensive shell plate damage to the bottom of its hull, which resulted in water ingress to several ballast tanks and flooding in the engine room.

The flooding was contained using the vessel’s bilge and ballast pumps, and submersible salvage pumps provided by the harbour authority.

There were no injuries to personnel and no damage to the environment. Continue reading “Report issued by MAIB on the grounding of Celtica Hav”
