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.

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.

At a time of political and economic uncertainty, the 21st annual Seawork exhibition was a clear demonstration that the UK and European commercial marine sector is open for business. With deals being struck, exhibitors showing confidence and visitor numbers up, Seawork was again successful at bringing together businesses, trading opportunities and new ideas.

The commercial marine sector is a vital facilitator to trade, security and maintenance of the world’s coastlines.
The UK Maritime Minister, Nusrat Ghani, opened the 21st edition of Seawork International on Tuesday 3 July with her speech focusing on the importance of the maritime sector, seafarer training, women in maritime, and Maritime 2050; the long-term strategy for the future of the UK maritime industries. As the engine of British trade, the maritime sector supports nearly Continue reading “Seawork 2018 speeds to success”

Stainless steel bolts at offshore facility fail due to corrosion cracking

A number of strain-hardened, Type 304 stainless steel bolts, (ASTM A193 B8, Class 2) failed unexpectedly at an offshore facility

The International Association of Oil & Gas Producers (IOGP) published an alert regarding an unexpected failure of certain kinds of strain-hardened Type 304 stainless steel bolts. The failure happened at an offshore facility during a pneumatic leak test of gas piping exiting a test separator.

The incident
A number of strain-hardened, Type 304 stainless steel bolts, (ASTM A193 B8, Class 2) failed unexpectedly at an offshore facility while a pneumatic leak test of gas piping exiting a test separator was being conducted.

Strain-hardening austenitic stainless steel nuts and bolts to increase their strength may increase their sensitivity to chloride-induced stress corrosion cracking (CISCC) and reduce their safe upper temperature limit. Other factors such as Continue reading “Stainless steel bolts at offshore facility fail due to corrosion cracking”

New innovation for inspecting mooring chains above and below water successfully trialled

The ground-breaking, new climbing robot, named RIMCAW (Robotic Inspection of Mooring Chains in Air and Water)

A robot designed to hook onto, and scale up and down, large mooring chains, both at sub-sea level and in the air – with a non-destructive testing (NDT), ultrasonic imaging system on board that scans for critical defects – has recently undergone successful field trials.

The ground-breaking, new climbing robot, named RIMCAW (Robotic Inspection of Mooring Chains in Air and Water), is the result of a year-long, fast-track project that secured funding from Innovate UK, the Government agency behind finding and driving the innovations that will grow the UK economy. It is being delivered by collaborative partners Computerised Information Technology Ltd, Innovative Technology and Science Ltd, London South Bank University and TWI Ltd.

The inspection of large mooring chains, such as those being increasingly employed in Continue reading “New innovation for inspecting mooring chains above and below water successfully trialled”
