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.

Moving Ahead Powerfully

The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.

First Ship with IMO Tier III EIAPP Engines Launched

The launch of the L’Astrolabe, a 72 metre polar logistics vessel fitted with a complete Wärtsilä propulsion machinery package and Wärtsilä NOR (NOx Reducer) SCR (Selective Catalytic Reduction) exhaust gas cleaning systems for all the main engines, took place on July 12. This is the first vessel operating with the International Maritime Organisation’s IMO Tier III EIAPP (Engine International Air Pollution Prevention) certified Wärtsilä diesel engines. The ship was built by PIRIOU (France) for the French Southern and Antarctic Lands Administration.

SCHOTTEL's New ProAnode Goes to Market

The first SCHOTTEL Rudderpropeller with the newly developed and patented ProAnode has left the German factory in Doerth. According to the manufacturer, ProAnode’s new form and position sets higher standards in corrosion protection, thereby extending the lifecycle of the thruster. Furthermore, moving the position of the anode from the outside surface into the cross-section of the nozzle tail leads to subsequent operational benefits, such as reduced flow interference, resulting in fuel savings.

The U.S. Navy has some spectacular vessels, from submarines to high speed RIBs. They also have dedicated ports and support facilities worldwide. A practical reality of all of this is that the Navy requires efficient and handy boats to support the warhorses. To meet this requirement John Myers of the naval architect firm Hockema & Whalen and Associates have developed a 30 by 15-foot tug with a 5.5-foot draft. Currently the Navy has 24 of these tugs, designated Work Boat Medium, on order from Modutech Marine Inc. of Tacoma, Wash.

Emissions Regulations Present Strategic Opportunity

The marine industry as a whole is responsible for about 2.5 percent of global greenhouse gas emissions. Shipbuilders and fleet owners have spent the last two decades adjusting to shifting emissions regulations since the introduction of the MARPOL Convention 1997 Protocol, which included specific regulations for the reduction of air pollution from marine vessels. Since then, there have been additions and amendments to ensure that the industry is doing its bit to better support the environment, with the latest regulation pulling forward lower caps in global emissions.

A New Breed of Tug

When markets expand niches are created, goes the logic. For builders of tugs, that market is “floating gas” and the expanding use of liquefied natural gas, or LNG, as a fuel. In support of LNG, there’ll be more oceangoing tug duty — the new floating storage and regasification units, or FSRUs, mean busier LNG carriers, and LNG cargo owners have an interest in tug escorts that share their “carbon footprint”. Still, new emissions rules offer ways to keep using refinery products, and the work of master tug designers suggests the new breeds of tugs are about more than fuel.

Supporting Silent Ships

Have you ever had problems talking to someone in a noisy environment such as a busy restaurant? The same happens to marine animals, which use sound to sense and interact with their environment: for communication, navigation, finding prey and even for self-defence. High ambient noise levels, which include a contribution from shipping, have an adverse impact on marine life. The world’s oceans are becoming increasingly noisy. While the size of the global commercial fleet more than doubled since the 1960s, anthropogenic noise in the oceans has actually increased eightfold.

A Versatile Harbor Tug

The azimuthing stern drive (ASD) format has become the norm for a great many tugs working in vessel assist around the world’s ports. They now far outnumber the full tractor tugs with the azimuthing drives set forward under the house as do they the cycloidal drive tugs. Often, the ASD tugs are dedicated ship-handling units with a single hawser winch forward. However, a lot of owners, looking to maintain diversity of applications and markets are adding a towing winch aft as well.

Z-Drive Collaboration on the Inland Waterways Expands

American Commercial Barge Line’s leadership and early adoption of ZF Marine’s z-drive propulsion technology underscores a growing trend on the inland waterways. American Commercial Barge Line (ACBL) has been around a long time – since 1915, to be exact – and along the way has developed into one of the dominant players in the inland marine transportation industry. With a passion for safety and a green footprint, ACBL has always embraced technology and innovation. That point was obvious when it made the decision to outfit at least 15 of its towboats with ZF Marine’s Z-drive systems.
