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.

Featuring a propeller diameter of 1.1 meters, the STPs enable a speed of up to 13.5 knots.
Bureau Veritas Certifies 3D Printed Propeller
Bureau Veritas (BV) said it has certified a new-generation 3D printed propeller manufactured by Naval Group for a Tripartite-class minehunter vessel.“This technology is promising and opens the room for further, more complex, innovations in additive manufacturing,” Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas Marine & Offshore.With its 2.5-meter span supported by five 200-kg blades, the propeller is said to be the largest metal 3D-printed propeller ever manufactured.
Historic Steam-driven Tug Returns to Service
One of the world’s oldest tugboats, the 117-year-old, steam-driven Daniel Adamson, is set to return to service offering short cruises along the River Weaver, a tributary of the fabled Mersey River in England, after the completion of a project to install new propeller shaft bearings.The 1903-built steamship, rescued from scrap merchants 15 years ago, was fully restored in 2016 at Birkenhead’s Cammell Laird yard, the original builder of the vessel. Thordon Bearings’ SXL water lubricated propeller shaft bearings were installed last year after competitor bearings failed.Chris Simmons…
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.
