ABS publishes guidance on reduced manning requirements for safe operations

Guidance on the technology, systems and regulations needed for minimizing human presence on offshore facilities has been published by ABS. The whitepaper evaluates technology, regulations, systems and design issues. Reduced Manning on Offshore Facilities introduces some of the considerations essential for remotely operating floating facilities from a control center located nearby or onshore. To enable reduced manning without compromising safety, real-time monitoring, control automation and maintenance procedures incorporating remote diagnostics and simulations with minimal human intervention will be required.

“By utilizing new technologies, the number of personnel on board offshore assets can be reduced, minimizing personnel exposure and potentially reducing overall capital and operating costs. Since a significant reduction in manning is a fundamental shift for the industry, it Continue reading “ABS publishes guidance on reduced manning requirements for safe operations”

Capsize of liftboat linked to inadequate preload procedure reveals NTSB report

NTSB issued an accident report has been issues by the National Transportation Safety Board (NTSB) on the overturning of lift-boat Kristin Faye while working alongside a platform in the Gulf of Mexico, in September 2019. The report identified the company’s inadequate preload procedure as key cause of the incident.

On 8 September 2019, about 1015 local time, the lift-boat Kristin Faye overturned while preparing to conduct work alongside a platform in the Gulf of Mexico, in Main Pass Block 64, about 18 miles east of Venice, Louisiana. All three crew members abandoned the vessel and were rescued. One person suffered minor injuries during the evacuation.

Consequently, an estimated 120 gallons of diesel fuel spilled into the water. The vessel was declared a constructive total loss at an estimated $750,000.

ABS updates Fatigue Assessment of Offshore Structures guide

ABS Guide: Fatigue Assessment of Offshore Structures
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”

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”

CTV shortage

A naval architect has warned that as European offshore wind markets continue to expand with larger and more ambitious projects, there is a looming shortage of Crew Transfer Vessels (CTV).

Chartwell Marine said that expedient investment in new builds will be required to tackle a shortage of 22m – 24m offshore wind crew transfer vessels, especially as build slots at yards are limited. Many of these existing vessels, commonly used for UK CTV operations, have reached retirement or require a refit following over 10 Continue reading “CTV shortage as offshore wind growth accelerates warns naval architect”

The salvage industry faces numerous challenges nowadays. Salvage cases tend to be more complicated technically and expensive. This is, in large measure, due to the increased size of vessels, increased values of their cargo and external influences such as demanding requirements from governmental organisations and the shore-based authorities. There are fewer cases for salvage companies and yet society’s expectations about protection of the environment have increased.

It is clear that salvage Salvage companies have much to contemplate. However, salvors are problem solvers, they will continue to stand ready to assist casualties all around the world. Salvors will always respond to a casualty no matter the Continue reading “Salvage companies make contribution to the marine environment and the shipping industry”

Load measurement for validation and data collection

Load sensors and data gathering have been a familiar part of the sport going back to the late era of IOR – in particular the final generation of IOR supermaxis like Bill Koch’s data-muncher Matador3. Today the technology is prevalent from the America’s Cup to big offshore trimarans to IMOCA, VO65s and including most of the modern superyacht fleet. The demand for data from raceboats is continually increasing – but it’s a form of technology that to date has been relatively inaccessible to the mainstream sailor, not to mention many designers and builders.

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

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.
