Efficiency Gains from Eliminating the Hub Vortex

There is hydrodynamic solution that delivers multiple benefits for ship owners facing increasingly tough regulatory requirements and rising operational costs, writes Dr. Batuhan Aktas*One area of ship operations that has attracted much attention in recent years due to the possibilities it represents for emissions reduction is that of cavitation. During ship operations, cavitation occurs because of vortices that build up and cause bubbles to collapse under the ship’s propeller. The results of this process include increased noise, vibration and energy usage.

Tech File: 3D Printed Prop for French Warship

Naval Group manufactured a new-generation propeller via a metal 3D printing process, mounted on a tripartite minehunter.This propeller is 2.5-m in diameter, supported by five 200-kg blades. The equipment left the workshops of the Naval Group site of Nantes-Indret in October 2020 for the site of Brest in order to be mounted on the ship's propeller shaft. As part of its major technical stop, the assembly was transferred to the submarine base to be mounted on the intermediate shaft of the Andromède in November.

Propeller Considerations for Inland River Pushboats

Inland river pushboats operate in a harsh environment. Transiting our rivers, bays, lakes and inland waterways, these vessels push barges between hubs of commerce. Swift currents, trash and debris, heavy traffic and narrow waterways are day-to-day realities for these vessels and operators.Pushboats have two typical modes of operation: steady-state (long haul running) and transient-dynamic operations (backing, maneuvering and acceleration). Unlike almost any other vessel type,…

Schottel CPPs for Damen-Design Russian Crab Vessels

Ten new crab-catching vessels for the Russian crab-catching companies Antey, Merlion and Aqvainvest will be propelled by Schottel. They will be built at different shipyards in Russia and are designed by Damen as design type CC 5712. Eight will be constructed at Nakhodka and a further two at Brothers Nobel shipyard. They are scheduled to enter operation from 2020 to 2024.“For this project we were looking for a manufacturer with outstanding expertise and great experience," said Ivan Mikhnov, President of the Group of Companies Antey.

Interview: John Batten, CEO, Twin Disc

How have major events such as the U.S./China trade war, oil price fall and COVID-19 impacted Twin Disc’s commercial marine business to date, and what adjustments have you made in response?These are the three things that I’ve been highlighting in employee communications and with investors over the last few months. For us, COVID was just the third punch after the other two. China is typically our second largest market after the U.S., and we lost lots of orders to our competitors as the trade war started to affect us. It’s rebounding a little, but it definitely impacted our sales into China.
