Experience Feedback A feeder container ship was berthing starboard side to a terminal on a clear, calm morning. The berthing pilot was assisted by the bridge team consisting of the Master, 3/O and helmsman. The forward mooring station was manned by the C/O, Bosun, an Ordinary Seaman (OS), a Trainee Seaman (trainee) and a deck cadet. The aft mooring station was manned by the 2/O and two ABs. The helmsman, who was also an AB, was expected to join the aft mooring party on completion of his bridge duties, once the vessel had been placed alongside its berth. Two tugs were assisting, one was made fast on the port quarter and the other was standing by forward to assist in accordance with pilot's orders. After closing with the berth, the aft backspring was sent ashore.The Master then instructed the C/O to send out the forward lines. While the cadet, OS and the trainee were lowering the forward backspring and a headline through the centreline panama chock, the Bosun, facing aft, operated the winch controls located inside the fore peak store access trunk. The C/O was standing on the starboard bulwark platform and directing the team with hand signals. As the ...

Recommends Safe Practices to Prevent Falls The Bureau of Safety and Environmental Enforcement (BSEE) today issued recommendations for safety measures developed from the investigation of an offshore accident which resulted in a fatality. The recommendations are being distributed through a Safety Alert: the safety alert is one of the tools BSEE uses to inform the offshore oil and gas industry of the circumstances surrounding an incident or a near miss. The alert also contains recommendations that should help prevent the recurrence of such an incident on the Outer Continental Shelf.The offshore accident which took place in April 2011 involved the lifting and moving of equipment during a decommissioning project. An offshore worker fell through an opening in the deck and suffered fatal injuries. The safety alert resulting from the investigation underscores the importance of existing safety requirements and recommends to operators:Fall protection such as barricading and vest harnesses should be available and used in the presence of open holes, or if holes may be exposed in the course of an operation;any operation used to lift equipment should be evaluated for all risks;appropriate tag lines (ropes or straps used to manually control the equipment being moved) and use of these tag ...

Lack of training in the operation and maintenance of the ship's OBA set The Australian Transport Safety Bureau (ATSB) issued the report of its investigation into the serious crew member injury on board a bulk carrier at sea off Eden, New South Wales on 11 October 2011.Investigation revealed that the crew member suffered burns when the air compressor he was using to fill an oxygen breathing apparatus (OBA) cylinder exploded. The explosion occurred when oil from the compressor ignited in the hot oxygen-rich environment.The crew had not been trained in the operation and maintenance of the ship's OBA set.For more information, click here.Source: ATSB

Due to the many lessons that have been learned World-leading ship science expert, Professor Ajit Shenoi, says that a seafaring tragedy on the scale of the Titanic disaster is unlikely to happen again.Professor Shenoi, who is the Director of the Southampton Marine and Maritime Institute at the University of Southampton, believes this is due to the many lessons that have been learned as a result of the tragedy 100 years ago."A detailed Board of Trade inquiry set up after the tragedy identified that the reasons behind the Titanic's sinking and the huge loss of life could be categorised under two headings," Professor Shenoi explains."Firstly, they relate to crew training and capabilities, as well as better communications and management on board ships, with clear allocations of responsibilities and regular checks on the actions and performance of crew. Secondly, they relate to the technology, whether it be the provision of lifeboats and life rafts, hull construction material and methods or watertight compartmentation."Professor Shenoi believes that the lessons learned from the disaster have been invaluable in ensuring that modern seafaring remains safe, and that when accidents do happen, lives are less likely to be lost."There are several lessons learned from the Titanic disaster ...

MAIB- Safety Digest 1/2012 MAIB issues Safety Digest 1/2012 regarding Lessons from Marine Accident Reports.This Safety Digest draws the attention of the marine community to some of the lessons arising from investigations into recent accidents and incidents. It contains information which has been determined up to the time of issue.This information is published to inform the shipping and fishing industries, the pleasure craft community and the public of the general circumstances of marine accidents and to draw out the lessons to be learned. The sole purpose of the Safety Digest is to prevent similar accidents happening again.The content must necessarily be regarded as tentative and subject to alteration or correction if additional evidence becomes available. The articles do not assign fault or blame nor do they determine liability. The lessons often extend beyond the events of the incidents themselves to ensure the maximum value can be achieved.You may view MAIB- Safety Digest 1/2012 by clicking hereSource: MAIB

Experience Feedback While loading at a terminal, the ship listed heavily to port during shifting of ballast. She finally became stable at about 16 degrees list whilst touching the bottom. At the time of the accident, the ship was approximately at even keel with a draft of about 9m. The owner's office and DNV ERS (Emergency Response Service) were immediately informed of the situation by the Master. They communicated by telephone whilst stability and strength calculations were carried out. Ballast was carefully shifted to starboard and after about five hours, the ship was reported to be back in an upright position.Extent of damageThere was no damage to the hull but cargo operations had to be stopped for a few hours. Fortunately, no cargo hoses were connected to the terminal at the time of the accident, otherwise they would have been damaged and might have resulted in pollution.Probable CauseThe ship is a double hull tanker. The cargo tanks are built without longitudinal centre line bulkhead and the wing ballast tanks are "L" shaped. Partially filled cargo tanks with no longitudinal bulkheads may cause large free surface effects to the extent that the initial metacentric height (GM) becomes negative. This creates initial ...

Experience Feedback In a recent case an entered vessel pressed up its ballast tanks in order to optimise trim and to satisfy mandatory stability criteria. The operation resulted in the unexpected flooding of a cargo hold causing extensive damage to cargo. An entered containership was carrying out ballast exchange operations mid voyage and pressed up one set of double bottom ballast tanks. On arrival it was observed that one of her holds had significant water inside and considerable damage to bottom stow cargo.The vessel had recently opened up several manhole covers for routine inspection of her ballast tanks.After the incident it was noted that the high level bilge alarms in the hold were not functioning.Whilst investigations are still continuing into this particular case it maybe timely to remind Members that poorly secured manhole covers are still a frequent cause of water ingress into holds, many, but not all, arising after drydocking where shore staff have not secured covers properly.If double bottom manhole covers are removed for whatever purpose it is recommended a note be made of where and when, this not only acts as an aide memoire but also helps in defending claims should water ingress occur Good maintenance should ...

Experience Feedback An offshore support vessel sailed from her shore base on a routine supply run to her designated oilfield. Her deck was loaded with a variety of tubing, casings, pallets, tool boxes, food containers and one large unpacked wooden cable reel, weighing about 11 tonnes. The reel was stowed with its axis fore-and-aft and was pre-slung with an extralong 12 mm steel wire sling passed through the very narrow central hole, which precluded threading any other securing rope or chain through the coil.The sling was unsuitable for securing, so the ship's crew secured the reel by pushing wooden wedges under it and tightening a chain around its girth. Additionally, the vessel's tugger wire was tensioned at the reel's mid-height. Soon after sailing, the ship rolled and pitched heavily in a gale, and the accelerations imposed large forces on the lashings. Suddenly, a link in the chain parted and the tugger wire instantly became slack. Subsequent movements displaced the wedges and the bridge watch observed the reel moving freely on the deck.The Master was called, speed reduced to minimum and heading altered into the sea and swell. With the ship now pitching gently, the crew managed to throw some square ...

It is not that simple anymore Until recently, a carrier could place heavy reliance on the "on deck cargo" exclusion clauses contained in the contracts of carriage. Quite justifiably, so one might say, bearing in mind that there has been a long chain of case law (The Danah, The Imvros, The Darya Tara) upholding the position that a carrier would be adequately sheltered in case of deck cargo lost overboard, as long as an exemption clause was in place in the bill of lading.The wind started to change after The Imvros which was a case heavily criticised in an article by Simon Baughen, Scholar, Reader at the University of Bristol, in 2000. This was a case of cargo loaded, stowed and lashed by the crew acting as servants of the charterers, who were responsible for loading, stowage and lashing under an un-amended NYPE clause 8. The Panel of Arbitrators found that the effective cause of the loss was the insufficiency of lashings which rendered the vessel unseaworthy. It weighted heavily on the mind of the Tribunal that it was charterers who were the ones contractually responsible for lashing, and hence owners won the argument. Charterers appealed on the basis that ...

Experience Feedback In heavy weather, in the course of routine rounds in his watch, the 4/E noticed that steel plates stowed in a storage rack against a bulkhead were inadequately secured and were beginning to move. Without considering the hazards or informing the senior watchkeeping engineer (2/E), he decided to re-stow the plates and re-secure the rack unassisted. During this process, the vessel suddenly rolled heavily.The plates toppled, trapping and crushing the 4/E's left leg. The 2/E, who was in the workshop at the time, heard the noise of the falling plates and a cry from the trapped 4/E. He immediately rushed to the location and sounded the emergency alarm. The Emergency Team assembled and rescued the 4/E, who was immediately given first aid. Due to the serious injury, and under radio medical advice, the vessel deviated to the nearest port, from where the injured crewmember was flown to Singapore in an air ambulance, for further medical treatment to his broken leg.Root cause/contributory factors1. Failure to inform other personnel of a hazardous situation and failure to seek assistance;2. Lack of experience and awareness - the young 4/E did not understand the risks in attempting to re-stow and re-secure the steel ...
