The loss of a towline shackle pin and deteriorated watertight fittings caused tugboat Mangilao to sink in the Pacific Ocean about 800 miles northwest of Guam, the National Transportation Safety Board (NTSB) has revealed in a Marine Accident Brief.

The 114 foot US flagged tugboat Mangilao sank on August 5, 2019 while being towed to a drydock in Subic Bay, Philippines by the 97 foot US flagged tug Chamorro. Both vessels were owned and operated by Cabras Marine Corporation. No one was aboard tugboat Mangilao and there were 10 crew members aboard the Chamorro.

No pollution nor injuries were reported in connection with the sinking. The 1982-built tugboat Mangilao, which was estimated to be worth Continue reading “Loss of towline shackle pin led to tugboat Mangilao sinking reveals NTSB accident report”

NTSB: incomplete safety procedures led to barge explosion

The National Transportation Safety Board (NTSB) has published Marine Accident Report 20-34 detailing the findings of its investigation involving the explosion of a barge at the Illinois Marine Towing Heritage Slip on the Chicago Ship and Sanitary Canal, Illinois on the 4 November 2019.

The barge explosion occurred when the IB1940 was being prepared for cleaning after its cargo of acetone had been unloaded. No injuries or pollution were reported in connection with the explosion. The barge, however, was declared a total constructive loss, valued at $1.75M. Continue reading “NTSB accident report concludes that incomplete safety procedures led to barge explosion”

The UK’s first sea-going electric ferries has set sail for the first time in Plymouth. Plymouth Boat Trips and Voyager Marine, Cornwall has partnered with the University of Plymouth, the University of Exeter, Teignbridge Propellers, MarRi-UK and EV Parts UK to make the project come to life.

Funded through the £1.4m Clean Maritime Call, a Maritime Research and Innovation UK (MarRI-UK) initiative supported by the Department for Transport (DfT), the project’s part of the UK’s goal of zero emission shipping.

The boat has been completely rebuilt over several months and will undergo rigorous trials – including assessments of its emissions – before it carries its first paying passengers in April 2021. Continue reading “New electric ferries take to the water in Plymouth and Paris”

A pair of vessels installed with all-electric propulsion from ABB have been approved to enter service at Niagara Falls. The zero-emission ferries named the James V. Glynn and the Nikola Tesla are said to be the first all-electric vessels built in the US, with power drawn from a high-capacity battery pack supplied and integrated by ABB. In addition to batteries, ABB has supplied an integrated power and propulsion solution for the newbuild zero-emission ferries, including an offshore charging system, enabling sustainable operation.

The roll-on roll-off ferry Estonia, carrying 803 passengers and 186 crew, sank on a stormy Baltic Sea shortly after midnight on September 28, 1994. The official investigation in 1997 concluded that the bow shield had failed, damaging the bow ramp and flooding the car deck. However, Sweden said that a Discovery Network documentary about the disaster included new underwater video images from the wreck site showing damage on the starboard side of the wreck.

“Estonia, Finland and Sweden have agreed that verification of the new information presented in the documentary will be made,” the foreign ministers of the three countries said in a joint statement on Monday.

The National Transportation Safety Board (NTSB) has released a mass of documentary evidence and factual reporting on the deadly fire aboard the Conception dive boat on 2 September 2019, one of the worst tragedies of its kind in living memory. The docket’s technical reports confirm that there was no assigned roving watch on the night of the fire, and they raise new questions about the level of safety training that the crew received before setting sail. The new material does not include any conclusions or recommendations, which will have to wait for the NTSB’s final report; that document will be released after a hearing scheduled for 20 October.

In multiple witness interviews, former crewmembers told NTSB investigators that they did not recall a designated watch or roving patrol Continue reading “NTSB releases mass of evidence on deadly Conception dive boat fire ahead of October hearing”

ABS updates Fatigue Assessment of Offshore Structures guide

ABS Guide: Fatigue Assessment of Offshore Structures

ABS has released its updated Fatigue Assessment of Offshore Structures guide, which incorporates updated approaches for addressing fatigue including new S-N curves and guidance regarding fatigue strength based on fracture mechanics.

Fatigue assessment is a process where the fatigue demand on a structural element is established and compared to the predicted fatigue strength of that element. One way to categorize a fatigue assessment technique is to say that it is based on a direct calculation of fatigue damage or expected fatigue life. Three important methods of assessment are the Simplified Method, the Spectral Method and the Deterministic Method. Alternatively, an indirect fatigue assessment may be performed by the Simplified Method, based on limiting a predicted (probabilistically defined) stress range to be at or below Continue reading “ABS updates Fatigue Assessment of Offshore Structures guide”

The National Transportation Safety Board (NTSB) has published an investigation report on the explosion and subsequent sinking of barge Alaganik in the Canal Passage, off Alaska in July 2019, which resulted in one fatality. The investigation identified ignition of gasoline vapor from a fuel cargo tank as key cause of the accident.

On 7 July 7 2019 an explosion occurred on the barge Alaganik as it was moored port side to the end of the Delong Dock in Whittier, Alaska. The vessel was serving as a platform for pumping fish cargo ashore from fishing vessels and tenders that came alongside. It also provided diesel fuel and gasoline to the fishing vessels. No cargo operations were ongoing when the explosion occurred.

Despite the efforts of shore-based responders to fight the ensuing fire, the vessel eventually sank in 60–80 feet of water. The Continue reading “Ignition of gas vapor onboard barge Alaganik the cause of fatal explosion reveals NTSB Report”

RMI publishes its annual report on marine casualties

RMI has published its Annual Report on the investigation of Marine Casualties, revealing that it received reports of 806 very serious marine casualties, marine incidents, and occurrences in 2019. Accidental falls, enclosed space incidents and collisions-groundings during pilotage were the main issues of concern last year.

Specifically, during 2019:
– 17 very serious casualties were reported to the Administrator. Two very serious casualties resulted in the constructive total loss of a ship, while 11 others resulted in the loss of one or more lives. Additionally, four occurred on yachts and resulted in their constructive total loss due to fire.
– Accidental falls were the leading cause of death during 2019, with seven lives lost. Four of these fatalities were the result of falls from height and three were falls overboard. Improper enclosed space entry also resulted in the loss of two seafarers
– There were 331 marine casualties.
– Serious injuries (resulting in incapacitation for 72 hours or more) were by far the most frequently occurring marine Continue reading “RMI publishes its annual report on marine casualties”

Autonomous Barge Master gangway landing solution set to improve safety for offshore structures

A new autonomous landing solution for offshore structures, called the Barge Master gangway, is designed to significantly improves both safety and performance.

Through a combination of radar technology, cameras and sensors, Bosch Rexroth’s system automatically attaches the landing from the ship to the required site without the need for manual input. This means that the operation is consistent and reliable, regardless of weather and ocean conditions.

After the automated landing procedure, the Barge Master gangway is held safely in place through a combination of motion compensation and the ship’s dynamic positioning.

“There are a number of benefits to the autonomous landing system,” says Rene Coppens, Business Development Manager for Continue reading “Autonomous Barge Master gangway landing solution set to improve safety for offshore structures”
