Holland Shipyards Group has revealed another order for multipurpose coastal cargo ships, making it five new vessel contracts in the last month.

The Dutch shipbuilder said it has signed a deal for two new shortsea vessels with domestic operator De Bock Maritiem.

This “expands their sustainable efforts in the shortsea market,” the yard added.

The 3,600-dwt vessels have been designed by Conoship to reduce emissions by 50% compared to regular ships.

They will transport dry cargo in holds with a capacity of 5,100 cbm.

No value has been given for the order.

The total energy efficiency of the coasters will be 30% higher than the IMO's Energy Efficiency Design Index requirement.

This is achieved by diesel-electric propulsion, an optimised propeller and hull shape, and very low power use.

The modular design means generators are located in an easily accessible space, making the vessel suited for future conversions to zero-carbon fuels.

“These two coasters prove that sustainability is an important pillar in the shortsea market. With possible future developments, the ships can grow along with sustainability,” Holland Shipyards said.

Wind-powered MPP order

Last month, the yard revealed an order from Hartel Shipping & Chartering for three MPP coasters of 3,800 dwt.

The tweendeckers will be capable of carrying project cargo.

The first vessel will be fitted with a VentiFoil wind propulsion system to cut fuel use by between 8% and 12%.

The deal marked a return to the shortsea market for the shipbuilder, which also constructs ferries and workboats.

De Bock Maritiem has a fleet of eight MPPs and general cargo ships, plus a small product tanker.
