Marine technology company Wartsila has secured a new order for the delivery of the fully integrated Wartsila Hybrid Solution for three newbuild eco-friendly 5,000dwt bulk carriers.

The order, which includes an option for an additional three vessels, was signed with Wartsila last month.

The 90m-long ships are being constructed at the Colombo Dockyard in Sri Lanka for Misje Eco Bulk, a unit of the Norway-based Misje Rederi group.

The hybrid propulsion solution will enable the ships to sail in and out of ports and perform cargo operations with a decreased emissions footprint.

From the project’s early stages, Wartsila and Misje Eco Bulk worked closely on the development of the efficient and sustainable propulsion solution.

The cooperation has resulted in the creation of a tailored solution that fully meets the owner’s requirements for operational flexibility, environmental sustainability and reduced operating expenses.

The ships are designed to be transformed to full zero emissions operations as the technology improves.

Wartsila Marine Power integrated systems and solutions director Grant Gassner 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.”

Misje Rederi technical manager Roald Misje said: “This newbuild project is in line with our ambition to have one of the world’s cleanest and most sustainable fleets. Our collaboration with Wartsila, 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.”

The order includes a Wartsila NOx Reducer (NOR), the power transmission system, controllable pitch propeller (CPP), Wartsila 20 main engine, Wartsila ProTouch bridge control system, electrical and automation systems, hybrid battery solutions, an energy management system (EMS), transformers, motors and shaft line.

The EMS in the hybrid Wartsila solution optimises the energy flows between the different power sources and storage, resulting in the highest efficiency possible.

Delivery of the equipment will begin late next year, with the first of the three ships scheduled to enter service in mid-2022.

The remaining vessels will be delivered at four-month intervals.

Earlier this month, CBO, a Brazilian operator of offshore support vessels, signed an agreement with Wartsila for the conversion of a vessel from its fleet to operate with hybrid propulsion.

CBO Flamengo, a platform supply vessel (PSV), will be the first vessel in Latin America to be equipped with a battery pack for hybrid propulsion.
