In the future, intelligent wireless bolts in wind turbines or satellites may be able to let the operator know when something is wrong. This could reduce the risk of human injuries and save cost.

A research team at NTNU in Gjøvik is working to create bolts that send an alert when something is not as it should be or when maintenance is needed. Each bolt must be able to contact a control center, which will receive messages from all intelligent bolts of this type in all installations around the world.

The team working on these wireless bolts includes Professor Michael Cheffena, two fellows and the manufacturer Dokka Fasteners. The vision of the research team is to develop wireless sensors to be installed inside the bolts. If the sensors detect that something is Continue reading “Are ‘Smart Bolts’ the thing of the future?”

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”

Futuristic 110 metre superyacht concept Elyon by Expleo set to break the superyacht mould

Expleo Design has unveiled a futuristic 110-metre (360-foot) superyacht concept named Elyon, with on-board accommodation for up to 30 guests.

According to Expleo Design, the organic shapes of the yacht “combine elements inspired by nature [and] assembled in a futuristic and innovative approach”. The studio’s main inspiration was a calm ocean wave, which explains its curvaceous exterior lines, which are described as being calm and elegant, yet firm and strong at the same time.

Elyon’s unique bow; the blending between decks; wide-glass windows; and her structural elements are combined with clean design and wide-open spaces to give the feeling of space, freedom and power.

Key entertainment features are Continue reading “Futuristic 110 metre superyacht concept Elyon by Expleo set to break the superyacht mould”

Marine HVAC supplier Heinen & Hopman has introduced a new service that can accurately predict where deficiencies in an HVAC system may occur before mounting a single piece of equipment on board a vessel.

According to Heinen & Hopman, computational-fluid dynamics (CFD) technology is used to analyse the HVAC-system design to validate whether the HVAC installation shall meet specific requirements.

In a recent press release, Heinen & Hopman outlined, “CFD is a well-established technology in many industries. With CFD technology, airflows can be realistically simulated to identify common HVAC problems, such as drafts, high levels of turbulence, high-pressure drop[s] and poor air-distribution. CFD considers everything from Continue reading “Heinen & Hopman launches new CFD-analysis service to reduce HVAC costs”

Class society DNV GL has published an up-to-date assessment of the most promising alternative marine fuels available today. The study is timely, as the 2020 fuel sulfur cap is fast approaching and the IMO has just decided to aim for a 50 percent cut in shipping’s carbon emissions.

The paper examines the prospects for the full range of alternatives – LNG, LPG, methanol, biofuel, hydrogen, fuel cells, wind and battery technologies – and it compares them to the use of conventional fuel, both Continue reading “DNV GL publishes its review of marine fuel alternatives”
