Longship inks newbuilding deal for TDW vessels with diesel-electric propulsion system

19 Jan 2023

Groningen based shipping company Longship on Wednesday (18 January) said it has developed an innovative ship design together with Dutch naval architect Ankerbeer BV which reduces emissions and is compliant with the EU Stage V standards applicable to non-road mobile machinery (NRMM).

Both will work together on a series of four ultra-low emission 8600 TDW vessels. 

The hull design and diesel-electric propulsion system delivers an ultra-low fuel consumption by using two low revolution engines to ensure a most efficient combustion. 

The fuel-efficient main propulsion generates a reduction in consumption of about 45% compared to the currently dominant ship types of similar size. Being an optimised design for the transport of biomass solid fuels, not only the specific consumption of the engines, but also the actual consumption per ton of cargo lowers emissions significantly.

“It is our corporate goal to substantially cut emissions and carbon intensity as industrial carrier when providing bespoke logistical solutions to our clients,” Longship CEO Øyvind Sivertsen said. “With these units we will meet requirements well before they become mandatory to the shipping industry”.

The hybrid propulsion system powering two azimuth thrusters. with low rpm and large diameter fixed propellers, can be retrofitted to run on alternative fuels that will replace fossil fuels in the future following the energy transition. At delivery, the ships will hold the class notation Prepared for Methanol C as hybrid alternative. 

The high cubic design featuring one fully box-shaped hold with 81.9 m clear hatch opening in length is well suited for break bulk and project cargoes, and able to sail in open-top condition. The ships will be built at Atlas Shipyard in Turkey with the first unit to be delivered in spring 2024.
