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
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)
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”

IMCA and OCIMF team up to improve OVID inspection system

The International Marine Contractors Association (IMCA) and the Oil Companies International Marine Forum (OCIMF) have agreed to establish a joint committee to review, share and progress developments of the Offshore Vessel Inspection Database (OVID) system.

The aim will be to improve the efficiency of the vessel assurance process by pooling the knowledge and expertise of oil companies and their marine contractors, while at the same time maintaining the highest standards of vessel assurance and risk management.

The joint committee will discuss and review various elements of the system on an ongoing basis, to ensure continuous improvement. Elements to be reviewed include:

– the Offshore Vessel Particulars Questionnaire (OVPQ),
– the Offshore Vessel Inspection Questionnaire (OVIQ) and
– the Offshore Vessel Management and Self Assessment (OVMSA).

Autonomous vessels – the challenges and opportunities in design

Autonomous vessels – the challenges and opportunities in design
Autonomous vessels – the challenges and opportunities in design

Automation presents a set of unique challenges to designers, insurers and operators of ships. In this article, reprinted from the Shipowners P&I Club website Keir Gravil, a naval architect at Frazer-Nash Consultancy in Bristol, UK discusses some of the key issues that could face automated ships of the future from a design perspective.

It is a truth recognised by many industries that the future of transportation lies with greater automation. Over the last 50 years we have seen huge changes not only in shipping, but in every form of transportation and vehicle. Aircraft now incorporate automation routinely on flights around the world, cars are being developed to drive themselves and many railways have been totally automated for some time. As each step in the evolution of transportation progresses, the human element of control is reduced or eliminated altogether. But what of shipping? Surely an industry the size and scope of international shipping faces unique challenges in the realm of automation?

The background
It is often the job of ship designers, especially those in the naval defence industry, to think ahead and anticipate future technological changes. One could argue that Continue reading “Autonomous vessels – the challenges and opportunities in design”
