Demand is growing for gearboxes advised with amalgam propulsion in mind, as tug owners seek to cut ammunition burning and emissions, while abbreviation the cardinal of architect sets on board.

A new bearing of gearboxes are actuality developed for four-stroke engines to accommodated the requirements of amalgam propulsion systems on harbour, escort and littoral assessment tugs.

These units can be installed on new argosy or retrofitted to absolute tugs, allowance abate ammunition consumption, agent amount and active time and emissions.

During Riviera Maritime Media’s contempo Gearboxes: gearing up for amalgam propulsion applications webinar, admiral from two gearbox manufacturers categorical the latest developments in this area. Katsa gearbox business sales administrator Mikko Happonen categorical the latest gearbox technology for four-stroke engines and how these can abate requirements on gensets.

This accident was captivated on 22 February 2021 as allotment of Riviera’s Abyssal Propulsion Webinar Week. The agitation looked at archetypal amalgam applications involving ability booty in and booty out (PTI/PTO) motors aback accumulated with abyssal engines and gensets.

During the discussion, Mr Happonen categorical developments in the Katsa L350 and L490 gearbox series. These are compact, afraid ability PTI/PTO gearboxes advised for abyssal amalgam applications.

“These gearboxes amalgamate two ability inputs to one capital achievement with adjustable clamp options,” said Mr Happonen.

The two capital applications are for active thrusters on workboats, adopted abutment argosy and tugs, and for propulsion drivetrains. The L350 has a ability ambit of 200-1,000 kW and the L490 ambit spans 1,000-2,500 kW. These gearboxes accept an chip wet running, multi-plate clutch.
