Tarbit Shipping, Sweden
Tarbit Shipping wanted to optimize its cargo operations as well as achieve economical operations in sailing. In addition, the vessels aimed to have PTI Take Me Home mode and PTI Boost mode. WE Tech chose The Switch PM shaft generator, which is driven by the main engine, to handle the cargo operations of the advanced LNG fueled tankers. In this mode, the propeller shaft is disconnected and the gas fueled main engine drives the shaft generator in variable speed.
North Sea Giant
North Sea Giant, one of the world’s largest and most advanced subsea construction vessels (OSV), has installed an innovative cost-saving solution to save fuel, emissions and maintenance costs. This system, based on The Switch’s unique Electronic Bus Link (EBL), enables the 18,151 GWT vessel to change between its diesel engines, running just one of its diesel engines during many operations, when necessary, rather than the standard three it used at all times in the past.

Eidesvik’s offshore supply vessel (OSV) Viking Princess can now operate with only three generators instead of four after a pioneering retrofit of an energy storage solution with an advanced The Switch DC-Hub at its heart. The move helps the 5,381 GWT ship save around a ton of fuel every day.

Terntank Rederi, Denmark
These novel product tankers are not only equipped with a low pressure gas dual fuel 2-stroke main engine but also with the direct-drive PM shaft generator solution provided by WE Tech. The direct-drive permanent magnet shaft generator is connected directly to the propeller shaft, so no step-up gearing is required.
Yaskawa Environmental Energy / The Switch signed its largest marine contract to date to provide 16 DC-Hubs and 32 frequency converters for a revolutionary new shuttle tanker concept developed by Teekay and Wärtsilä. The four tankers will be built by Samsung Heavy Industries in South Korea, and deliveries to Wärtsilä are set for September 2018.
