New vessels built in China to feature hybrid propulsion systems with methanol engine - SAFETY4SEA - Safety4Sea

Wärtsilä volition proviso its hybrid propulsion strategy for 4 caller dense assistance vessels being built astatine the Wuhu Shipyard successful China.

The vessels person been contracted by SAL Heavy Lift GmbH, a German dense assistance and task cargo specializer and portion of the Harren Group, successful practice with its joint-venture partner, Netherlands-based Jumbo Shipping. There is an enactment for an further 2 vessels.

Wärtsilä’s innovative hybrid system will minimise the ships’ CO2 emissions, frankincense supporting the marine sector’s decarbonisation ambitions. The strategy volition diagnostic a variable-speed Wärtsilä 32 main motor susceptible of operating with methanol fuel.

This volition truthful marque these ships among the archetypal to beryllium prepared to run connected methanol, a cleanable burning sulphur-free alternate to accepted fossil-based marine fuels. They volition besides beryllium the archetypal methanol susceptible ships to employment a adaptable velocity main motor successful a hybrid installation.

The hybrid strategy besides includes Energy Storage, a PTO/PTI generator and motor, a multidrive converter, and the Wärtsilä Energy Management System for controlling and optimising the hybrid operations. The Energy Storage strategy volition beryllium based connected Lithium-Titanium-Oxide (LTO) batteries, which tin grip higher amounts of heavy cycles than mean Lithium-Ion based systems.

The ESS volition importantly trim the substance depletion and/or the indispensable size of the port’s electrical enactment transportation during crane operations portion besides providing substance savings astatine oversea by reducing Engine Load fluctuations successful unsmooth seas.

The ships are scheduled for transportation successful 2025 and volition beryllium utilized chiefly to enactment upwind workplace installations.
