World First: Printed Hollow Prop Blade
French defense contractor Naval Group and French elite engineering school Centrale Nantes have printed the first demonstrator of hollow propeller blades by metal additive manufacturing as part of the European H2020 project, RAMSSES.Naval Group, formerly known as DCNS, said that this collaborative program, funded by the European Commission, aims to reduce the environmental impact of ships.Centrale Nantes and Naval Group are taking the lead within this project on the production…
First Class Approved 3D Printed Ship’s Propeller Unveiled
The world’s first Class approved 3D printed ship’s propeller, the WAAMpeller, has been unveiled following rigorous testing verified by Bureau Veritas at Damen Shipyard Group’s headquarters in the Netherlands. The groundbreaking propeller is the result of collaboration between RAMLAB, Promarin, Autodesk, Bureau Veritas and Damen, who started pooling 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.
3D Printed Ship’s Propeller Prototype Produced
A prototype of the world’s first class approved ship’s propeller manufactured using 3D printing techniques has been produced by a cooperative consortium of companies that includes Damen Shipyards Group, Rotterdam Additive Manufacturing LAB (RAMLAB), Promarin, Autodesk and Bureau Veritas. The 1,350mm diameter propeller – named WAAMpeller – was fabricated from a Nickel Aluminium Bronze (NAB) alloy at RAMLAB in the Port of Rotterdam. The propeller was produced with the Wire Arc Additive Manufacturing (WAAM) method using a Valk welding system and Autodesk software.
WAAMpeller: World First Class-Approved 3D Printed Ship’s Propeller
A consortium of organizations are working toward a landmark achievement in the maritime sectors: creating the world's first class-approved 3D-printed ship's propeller. As many sectors of the shipbuilding industry suffer due to overcapacity, it is this type of innovative leap that will -- if successful -- separate the next generation of leaders in the sector. In the effort a cooperative consortium of Damen Shipyards Group, RAMLAB, Promarin, Autodesk and Bureau Veritas aim to develop the world’s first class approved 3D printed ship’s propeller, dubbed WAAMpeller.
3D Printing Enables Quick Turbocharger Repair
The first 3D-printed nozzle ring for marine turbochargers has been developed using exotic super metal alloy, enables the reconstruction of worn out components for shorter repair times. According to the technology’s developer, Tru-Marine, the premature erosion of nozzle rings has been a commonly reported problem, and in such situations, spare part replacements are often unavailable and come with long lead times at high costs. The company has therefore developed proprietary processes in 3D printing…
First Pieces of Scrubber System Fitted on AIDAluna
AIDAluna left the Blohm + Voss shipyard in Hamburg yesterday after extensive maintenance work was carried out from April 26 to May 5, 2014. Work on the cruise ship included among others the installation of the first elements of a comprehensive filter system with which AIDA Cruises is gradually fitting out its fleet. The system for the treatment of exhaust gas emissions, which was developed within the Carnival Group, uses a new technology built in a compact form making it possible to technically integrate all of the main cleaning stages for the first time.
New Book: 'Ninety Percent of Everything: Inside Shipping ...'
'Eye-opening and compelling', according to Amazon where the book is on sale, the overlooked world of freight shipping, revealed as the foundation of our civilization. On ship-tracking websites, the waters are black with dots. Each dot is a ship; each ship is laden with boxes; each box is laden with goods. In postindustrial economies, we no longer produce but buy. We buy, so we must ship. Without shipping there would be no clothes, food, paper, or fuel. Without all those dots, the world would not work.
First 3-D Printer Ship Model
Naval Surface Warfare Center (NSWC) Carderock complete a fabricated model of the hospital ship 'USNS Comfort'. The state-of-the-art 3-D printer, which is one of four in the United States, provides Carderock with the capability to deliver large, complex ship models. Additionally, the ship models require less assembly time and can be fabricated unattended, 24 hours a day. "3D printing technology is currently being used in industry to produce parts, structures and models for various applications," said NSWC Carderock engineer Francisco "Paco" Rodriguez.
