Contemporary UUV Propulsor Design
From the standpoint of vehicle propulsion physics, an unmanned underwater vehicle (UUV) is little different from your personal ski boat or a tanker. It shares the Vessel-Propulsor-Drive system model, which allows a Propulsor to convert Drive energy into thrust for the purpose of moving a Vessel. The basic principles of thrust equilibrium and motion are common to all three, as are the translation of rotational energy into axial thrust by the central element of the system – the…

Glosten, Bieker Boats Design Ultra Fuel-Efficient Vessel
The provider of naval architecture and marine engineering services Glosten and marine craft builder Bieker Boats have joined forces to bring modern composite hydrofoil technology to the passenger vessel community.This collaboration draws on Bieker Boats’ years of experience designing fast foil-born boats and Glosten’s design of passenger vessels for public and private clients over the past 50 years, said a press note from Glosten."This ultra-efficient vessel requires less than half the installed power of a typical passenger catamaran, resulting in a 50% reduction in fuel consumption.
Langh Tech Delivers Scrubber Systems to Polaris Fleet
Langh Tech and STX Offshore & Shipbuilding (STX O&S) have signed a deal for scrubber retrofits on seven vessels in the Polaris fleet. The four 180K bulkers and the three 300K VLOCs in the fleet will be equipped with Langh Tech’s open loop scrubbers.The scrubber installations will be done as turn key deliveries by STX O&S. On each of the vessels the main engine and the three auxiliaries are connected to the scrubber. The scrubbers are multi-inlet type and Langh Tech delivers all the equipment necessary for a fully working open loop system.
Mercury Marine Celebrates 80th Anniversary in 2019

Aker Arctic Bronze Propellers for Ice-class Ships
Bronze has been the preferred material for open water and low ice class ship propellers for decades, said Finnish engineering company Aker Arctic that operates an ice model test basin in Helsinki."Few years ago, Aker Arctic began investigating the possibility of using it also in high ice class vessels. In November 2018, the first bronze propellers based on the new strength dimensioning criteria were installed on the Finnish ice class 1A ASD tug Calypso," said a statement from the designer of icebreakers.While bronze is not as strong as stainless steel…

Digital Feature Extraction with PropCad Premium 2018
A new utility automates feature extraction from 3D CAD data.Marine propellers can last a long time – it is not uncommon to find a vessel running on its original set of propellers. Sometimes, these propellers even outlive the companies that produced them. For example, some large volume propeller manufacturers have permanently closed their doors and patterns, molds, and design data have been scattered to unknown corners of the globe. It’s fair to say that while the propeller manufacturing industry has seen growth…

New Great Harbor TT35 Powered by Suzuki From Mastry
The new Great Harbor Trawler TT35 from Mirage Manufacturing is a unique, outboard-powered liveaboard cruiser. When the father and son design team of Ken and Travis Fickett went looking for the ideal power solution, they turned to Mastry Engine Center and the ultra-efficient Suzuki DF60AV.The choice of Suzuki outboard power for the TT35 has many advantages. Because the engines are outside the hull, it frees-up internal space for storage. Inside, it's exceptionally quiet with no perceptible vibration. Maintenance is simpler with easier access than an inboard.
