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.
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.

Bangkok’s Chao Phraya Tourist Boat
Many visitors to Bangkok will experience a ride on the Chao Phraya Express boats. These long, sleek, wooden, commuter boats, with their dramatically raked bows, are a staple of the river’s traffic. They can also be very crowded and, with many stops, a bit of a challenge to the tourist. A popular alternative is the tourist boats. These vessels have a more limited route and series of stops, all of which are near important tourist destinations such as the Grand Palace and Wat Arun, the Temple of the Dawn.
Honda Marine Debuts New Outboard Jet Models
Boaters who want to explore the shallows now have three new engine choices from which to choose with the launch of the jet-driven Honda 40 Jet, 65 Jet and 105 Jet Honda Marine outboard motors.

ABB’s fourth generation DEGO software collates data from sensors monitoring 60 shipboard parameters in real time…
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.

The recent introduction of the Premium Edition now brings a higher-order distributed-analytical (“2D”) hull form analysis to design optimization.
US Navy: Bigger is Better, but at What Cost?
The U.S. Navy has a balanced fleet, but it wants to grow bigger and better. Will the budget allow both? Maritime Reporter's March 2017 cover story on the U.S. Navy was all about the numbers. There exists several plans to grow the fleet beyond the current number of 308 ships, the Mitre recommendation of 414 ships, the Center for Strategic and Budgetary Assessment 340-ship proposal, and the Navy’s decision to grow the fleet to 355 ships, and the Trump administration’s 350. With so many numbers being bandied about, there are even more suggestions on how to get there.
MAN Diesel & Turbo, MM-Offshore Partner
At a signing ceremony on June 1 at the Nor-Shipping trade fair in Norway, engines manufacturer MAN Diesel & Turbo signed a cooperation agreement with ship equipment supplier MM-Offshore.

Typical marine applications will be larger fishing vessels…
A Hybrid Drive’s Digital Landscape
Hybrid drive and potential fuel savings are well known — from 10 to 30 percent, according to the sources we’ve written about over the years. Less known, is the potential need to purchase some sort of remote monitoring package to complement that diesel-electric or battery hybrid system from a system operator in order to secure the maximum safety benefits. As the count of system operators offering hybrid drives grows, so too, it seems, there’s continuous need to look at who they are and what they’re offering.
Nor-Lines, Rolls-Royce Sign Service Agreement
Nor Lines and Rolls-Royce have signed a “Power-by-the-Hour” service agreement for the two vessels Kvitbjørn and Kvitnos.

DNV GL Adds Asymmetric Stern To ECO Lines
A vessel with an asymmetric stern has a twisted aft shape that is designed to account for the differing flow conditions on each side of the propeller. The idea emerged in the 1960s, but due to the difficulty of manually developing the optimal shape, this design failed to make a large impact at the time. DNV GL has revisited the idea and, using high-fidelity computer fluid dynamics (CFD) in combination with parametric formal optimization, the classification society can now offer ship owners the option of incorporating an asymmetric stern into their new vessels.
Fairbanks Morse's Diesel Gensets for US Navy’s New Warship
Fairbanks Morse, an EnPro Industries company, will supply the Ship Service Diesel Generator (SSDG) sets for electric power generation system aboard the U.S. Navy’s newest America class amphibious assault warship, LHA 8. Construction of the generator sets will begin later this year. They are scheduled to be delivered to shipbuilder Huntington Ingalls Industries in Pascagoula, Miss., in 2019. The six generator sets, powered by 12-cylinder Colt-Pielstick PA6B diesel engines will deliver 24 MW of electrical power and are some of the largest medium speed diesel engines built in the United States.
ABB Shaft Generators, Turbochargers for DFDS Vessels
ABB shaft generators will raise the energy efficiency on two DFDS vessels which have been designed to meet the latest environmental regulations. Two shaft generators will be installed in each of the cargo Ro-Ro ships allowing the main engines to operate at a wider, more optimal speed range. The shaft generator system takes its power from main engines, thereby increasing safety if there is a failure on the auxiliary engine. The ships’ main engines will also be turbocharged by ABB’s latest generation technology.

Auckland-headquartered Henley Group, an approved Thordon distributor, with a history dating to 1917, secured the contract to design and supply Korora’s complete drivetrain…
IMO 2020: The Future of Fuel
