Norway’s Petroleum Safety Authority, PSA,  says an improperly adjusted winch brake, which it refers to as ‘vulnerable’, led to the unintentionally launch of a lifeboat from the mobile unit Mærsk Giant at about 05.10 on Wednesday 14 January 2015.

This incident occurred during testing of the lifeboat systems.

During testing, one of the lifeboats unintentionally descended to the sea. Efforts were made to activate the manual brake on the lifeboat winch, but it was not working. The lifeboat entered the water and drifted beneath the unit. The steel wires holding it were eventually torn off.

After the incident, the lifeboat drifted away from Mærsk Giant, accompanied by a standby vessel. The lifeboat eventually reached land at Obrestad south of Stavanger.

Nobody was in the lifeboat when the incident occurred, and no personnel were injured.

The PSA conducted an investigation which established that the direct cause of the incident was a reduction in the braking effect of the brake on the lifeboat winch owing to faulty adjustment. If the manual brake failed during maintenance with people in the lifeboat, or during an actual evacuation, serious personal injury or deaths could have resulted.

Should the lifeboat have descended during an actual evacuation, a partially filled lifeboat could have reached the sea without a lifeboat captain on board. The PSA also considers it likely that people would have been at risk of falling from the lifeboat or the muster area should a descent have started. The potential consequence could be fatalities.

Five nonconformities were identified by this investigation. These related to

  • maintenance routines for the lifeboat davit system
  • training
  • procedures relating to lifeboats and evacuation
  • periodic programme for competent control and ensuring the expertise of personnel carrying out maintenance work
  • qualification and follow-up of contractors.

Mærsk Giant is operated by Maersk Drilling Norge.

Big Orange, the crunch on collisions?

Norway’s PSA is concerned that the many collisions between vessels and installations on the NCS could lead to major accidents. It has called for big improvements in ship operation.

A dramatic impact hit the Norwegian headlines in the summer of 2009, when well stimulation vessel Big Orange XVIII ran into the Ekofisk 2/4 W platform at a speed of almost 10 knots.

Extensive damage was caused, and the PSA’s investigation found that the incident, under slightly changed circumstances, could have developed into a major accident.

But this event was by no means unique. Collisions have been occurring on the NCS ever since the oil industry arrived in Norway during the mid-1960s. Continue reading »

Transocean Leader, key personnel did not understand the risk management system used onboard.

Deepwater Horizon owner Transocean has come under pressure from Norway’s Petroleum Safety Authority following an audit covering the company’s management of major accident risk and handling of barriers. In addition to some 14 non-conformities ranging from inappropriate headoffice directives to firefighting and lifesaving equipment the PSA found that manager were not familiar with the risk management methodology it recently introduced.

The four-day audit of the Transocean Leader facility, preceded by a one-day management meeting onshore

Transocean is  implementing a Bow-tie methodology which illustrate hazardous situations and probability-reducing barriers on one side, and consequence-reducing barriers following incidents on the other side of a diagram that resembles a bow-tie.

On the Transocean Leader facility, the PSA verified Transocean’s management and knowledge of major accident risk by reviewing two major accident scenarios in the form of ”table-top” exercises related to the facility’s defined hazard and accident situations.

Says PSA: “The audit activity was well-organised by Transocean”

Transocean’s main management defined which defined situations of hazards and accidents, DFUs, can primarily trigger major accidents. Currently there is not a complete overview of the operational and organisational barrier systems, and the company lacks a systematic approach in the area..

Federal Kivalina aground

Bulk carrier Federal Kivalina ran aground at 0510 hours on 6 October 2008 at Årsundøya in Møre and Romsdal county, Norway, while under pilotage as the ship’s electrician analysed an alleged fault in the AIS. Norway’s Accident Investigation Board highlights bridge team management, passage planning and the master-pilot exchange as vectors in the incident.

After boarding the vessel the pilot tried to connect his laptop computer to the ship’s AIS using the pilot plug but failed and reported the problem to the master. The master called the ship’s electrician who attempted to locate the fault.

A trainee fisherman lost the majority of his toes on the left foot in an accident on a trawler while fishing for Norwegian lobsters.

After having emptied one of the trawls into two fish tanks on the aft deck, the trainee fisherman waited by one of the corners of the hatch while the skipper closed it by use of hydraulics.

The left foot of the trainee was in the way of the hatch which either the trainee or the skipper noticed until the foot was squeezed severely by the closing hatch.

The trainee was wearing regular rubber boots.

Says it all.

The end of Maritime enquiries in Norway


WESMANS AS, Oslo correspondent for the Swedish Club, reports that Norway is to replace its century and a half old public enquiry system into maritime accidents, bringing it more into line with growing international practice and the IMO’s code of conduct for maritime casualty investigation.

Says Wesmans: “From 1 July, almost 150 years of maritime inquires after shipping disasters will be history. Seafarers and shipping companies will no longer have to explain themselves at public hearings.

“When the maritime inquiries disappear, the parties involved will have to give their statements directly to the police, the Accident Investigation Board Norway (AIBN) or the Norwegian Maritime Directorate. This will be regulated through an amendment of the existing maritime law.

“AIBN’s investigations of shipping disasters are meant to prevent new accidents and serious incidents, and improve safety at sea in general. The investigations shall not distribute guilt or responsibility.

“The prosecuting part of the investigations carried out by the maritime inspectors until now, will be transferred to the North Sea/Environmental Section of Rogaland police district. The unit will be responsible for the investigation and the application for a prosecution in shipping cases within their own districts. In addition, the unit will give assistance to other police districts that are investigating accidents occurring in their police districts.

“Resulting from the amendment of the maritime law, the Norwegian Maritime Directorate will play a more active part in the follow-up of accidents. The Directorate will also have the opportunity to carry out their own investigations into accidents. The Norwegian Maritime Directorate will mainly investigate the accidents which AIBN chooses not to investigate.

“The Norwegian Maritime Directorate is very committed to the prevention of accidents. We will therefore focus our inspections on those parts of the shipping industry where risk of accidents is the greatest. One example is the type of vessels that are subject to the most groundings.

“According to the new arrangement, notice of shipping disasters with loss of lives or considerable damage to ship, person or environment shall be given to a rescue coordination centre, which will make sure that other authorities are notified of the incident.

“A written report on the incident shall be submitted directly to the Norwegian Maritime Directorate within 72 hours.

“The Norwegian Maritime Directorate is hoping that the establishment of an independent investigating body, in addition to the Directorate’s own ability to investigate accidents, will give a better understanding of what causes accidents.”
