The US Navy’s Office of Naval Research has recently worked with the operator of the retired WWII-era carrier USS Midway to test a drone-based corrosion detection system.
ONR’s fast-prototyping division, TechSolutions, has developed a sensor package and processing system called Topside Drone that can detect corrosion and anomalies on hull surfaces automatically, saving time in surveys. The technology will be used to inspect and detect material defects, corrosion, warping and other forms of deterioration.
Saipem, the energy and infrastructure solution provider, is implementing DNV GL’s hull planned maintenance system, ShipManager Hull, based on 3D digital twins of crane and pipelaying vessels.
DNV GL will supply its advanced software, ShipManager Hull, for implementation on five vessels of the Saipem fleet. It will start with Saipem 7000, one of the world’s largest crane vessels with a lifting capability of 14,000 tonnes at 42 meters. Indeed, crane vessels are exposed to high stresses during lifting, demanding particular attention to structural integrity. The frequent ballasting of the vessel increases the need for efficient monitoring of ballast tank corrosion. Saipem will be able to use a digital twin of the entire structure for optimal planning of periodic inspections and dry-dock repairs.
The world’s largest all-electric ferry has completed its first commercial voyage between the ports of Søby and Fynshav in southern Denmark.
This revolutionary ship, e-ferry Ellen, capable of carrying approximately 30 vehicles and 200 passengers, is powered by a battery system with an unprecedented capacity of 4.3MWh provided by Leclanché SA one of the world’s leading energy storage companies. The motor system was supplied by Danfoss Editron.
“A fire in the engine room is any seafarer’s worst nightmare,” says Tom Backlund, Wärtsilä’s General Manager Large Bore Engines.
This is especially true when it comes to fuel leakages in vessel engine rooms. This is why the International Convention for the Safety of Life at Sea (SOLAS) regulation, enforced by the International Maritime Organisation (IMO), stipulates a number of minimum safety standards for operations throughout the vessel, including the engine room, with a strict limit for splash guards’ surface temperatures that could ignite liquid and cause fires.
