Wärtsilä has been selected to supply a fully-integrated power solution for three newbuild eco-friendly 5,000 dwt bulk carriers, enabling a greatly decreased emissions footprint for the 90m long ships which are being built at the Colombo Dockyard in Sri Lanka for Misje Eco Bulk, part of the Norway based Misje Rederi group.

The Wärtsilä Hybrid Solution will enable the vessels to sail in and out of port, and to perform cargo operations, completely emissions-free. The Wärtsilä scope of supply includes a Wärtsilä 20 main engine, with Wärtsilä NOx Reducer (NOR), power transmission system, CP propeller, Wärtsilä ProTouch bridge control system, electrical and automation systems, hybrid battery solutions, energy management system (EMS), transformers, motors and shaft line. The EMS functions as the ‘brain’ in the Wärtsilä Hybrid solution optimising the energy flows between the different power sources, storage and consumers to achieve optimum efficiency.

The development of the efficient and sustainable propulsion solution was carried out from an early stage of the project in close cooperation between Wärtsilä and Misje Eco Bulk. This approach enabled a tailored solution that meets the owner’s requirements regarding reduced operating costs, operational flexibility, and environmental sustainability. The vessels are designed to be converted to full zero emissions operation as the technology develops.

“This newbuild project is in line with our ambition to have one of the world’s cleanest and most sustainable fleets. Our collaboration with Wärtsilä, and their deep understanding and know-how of hybrid technology, make this ambition achievable, and we see great benefit in this very strong integrated solution to us as the owner from a lifecycle perspective,” said Roald Misje, Technical Manager, Misje Rederi.

Grant Gassner, Director Integrated Systems and Solutions, Wärtsilä Marine Power, said: “We are extremely honoured to have worked closely with Misje Eco Bulk to develop this fully integrated hybrid propulsion solution, which represents a new overall benchmark for bulk carriers in terms of operational flexibility, high efficiency, and low emission levels. We look forward to continuing our good collaboration with both Misje and Colombo Dockyard during the construction and commissioning of these ground-breaking vessels.”

Delivery of the equipment will commence in autumn 2021, and the first of the three ships is scheduled to enter service in mid-2022. The subsequent vessels will be delivered at four month intervals.
