Taking advanced marine solutions to the world

The Switch DC-Hub experts

Helping the marine industry become greener is at the center of all we do.
We don’t expect one technological breakthrough to solve the challenge of sustainable shipping. Required is a range of solutions, each making its own contribution.
In the marine industry, our innovative drive trains enable shipowners to future-proof their fleets by lowering operational costs, enabling profitable power generation and energy use, as well as reducing the cost to the environment.
We head towards a cleaner future with our advanced solutions, including a permanent magnet shaft generator, electric propulsion, Power Drives and DC-Hub.

Permanent magnet technology

PMM-1000, Permanent magnet machine

Our permanent magnet (PM) machines and frequency converters are game changers when it comes to reaching the highest energy efficiency, lowering the cost of operations and complying with future environmental legislation and safety regulations. The PM machine can be used either as a generator or a motor.

Shaft generators

container ship, short shaft, shaft generators

For shaft generators, our mechanical solution based on permanent magnet generators (PMG) and frequency converters allows the auxiliary generators to be off most of the time and enables the ship to operate at variable speed while producing electricity.

Talking point: Game-changer

Electric propulsion

Electric motor, electric propulsion

In electric propulsion, we offer special seafaring vessels, like ferries, cruise lines, tugboats and icebreakers, the opportunity to take advantage of lower operational costs by optimizing the fuel consumption of the diesel engine.

Talking point: Sailing on gold

North Sea Giant

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.

Viking Princess

Viking Princess

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.

ESL Shipping, Finland

WE Tech received an order to deliver The Switch direct-drive permanent magnet shaft generator solution to two new 25,600 dwt dual-fueled handysize bulk carriers, with an option for two more. The vessels are owned by the Finnish ship owner ESL Shipping Ltd., and built at Qingshan Shipyard of Sinotrans & CSC SBICO in China.

Transport Desgagnés, Canada

The Switch delivered its direct-drive PM shaft generators to WE Tech for a series of 2+2 new building vessels for Canada-based Transport Desgagnés, Inc. These new vessels will be built by Besiktas Gemi Insa A.S. Turkey.

Saga LNG Shipping, China

The Switch received a PM shaft generator order with an option of one more from the energy-efficient solution provider WE Tech for an LNG carrier owned by Saga LNG Shipping Pte. Ltd. Deliveries will commence in October 2016.

Wallenius Shipping, Sweden

The Switch delivered its direct-drive PM shaft generators to WE Tech for a series of four new building vessels from Wallenius Shipping AB.

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.
