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.

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. The impetus for the agreement stems from industry efforts to enhance ship performance. These have resulted in highly efficient propulsion and maneuvering systems with both now optimized – individually – essentially to perfection. He added, “A number of recent projects have already documented how beneficial such a combined optimization could be for ship designers…

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.

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.
