Belgium’s DEME Group has welcomed 2018 with a keel laying ceremony for Spartacus at the Royal IHC shipyard in Krimpen aan den Ijssel in the Netherlands. This new cutter suction dredger is set to be the most powerful such vessel of its type in the world.

With a total installed power of 44,180kW the vessel will be able to cut harder soils at speeds previously impossible. This will allow certain works to be undertaken by the cutter dredger rather than reliance upon the use of dynamite for blasting.

Spartacus will be able to dredge to depths of 45m, extending the capabilities Continue reading “Green dredging vessel Spartacus has keel laid in the Netherlands”

Inspecting hull integrity remotely with a new submersible is now possible with Deep Trekker ™

Deep Trekker ™ means underwater hull integrity inspections can be made remotely

Deep Trekker ™ has added to its fleet of portable, robust underwater drone robots; the DT640 Utility Crawler is designed to perform a multitude of underwater tasks.

This is a brand new inspection and service robot and is said to be the first three-wheeled vehicle of its kind. Its modular construction allows for the unit to be equipped with multiple operative attachments making the DT640 more than just an inspection vehicle. The Utility Crawler can be outfitted with magnetic wheels, pressure washer, vacuum, thickness gauge and a dozer.

Wingsail technology saves fuel and reduces emissions

Oceanfoil’s wingsail technology could achieve an average fuel consumption and emissions saving of 14% on a mid-sized tanker vessel.

This is the research finding from BMT, who said that Oceanfoil’s fuel-assist aerofoil technology, which uses wingsails to capture effective directional thrust from wind power, could also save up to up to 20% in certain wind and sea conditions.

Charles Moray, managing director of Oceanfoil, commented: “Oceanfoil’s ‘wingsail’, is a propulsion assist technology that is well suited for tankers and bulk carriers, which provide good opportunity for the wingsails to use the wind to create forward thrust – thus reducing reliance upon the vessel’s main engines.

WAAMpeller 3D printed ships’ propeller approved

Following a rigorous testing process, verified by Bureau Veritas, the world’s first Class approved 3D printed ship’s propeller, the WAAMpeller, has been unveiled at Damen Shipyard Group’s headquarters in the Netherlands.

The five-company partnership started pooling their collective resources and knowledge to develop the world’s first 3D printed ship’s propeller seven months ago. Promarin provided the design of the triple-blade propeller. The Port of Rotterdam’s RAMLAB (Rotterdam Additive Manufacturing LAB) carried out fabrication using Wire Arc Additive Manufacturing (WAAM) techniques, supported by Autodesk’s expertise in software, robotics and additive manufacturing.

Smallest Surface Effect Ship Sea Puffin under construction by ESNA

What is thought to be the smallest SES (Surface Effect Ship) workboat is being built in Denmark for operations on wind farms. With a length of just 15.8 metres, this new SES is being built for operators Wind Partner who plan to charter the boat out to operators.

The design for this SES, called Sea Puffin, has been developed by naval architects Espeland & Skomedal (ESNA) of Norway and features a catamaran hull with fabric skirts enclosing the air cushion between the hulls. It is designed to be capable of being launched with a standard 15 tonne single point davit system.
