Skarv Shipping Solutions has increased its order for ‘zero carbon project carriers’ from Shandong Huanghai Shipbuilding Co. Ltd to five ships, extending its commitment to a Berg Propulsion package that optimizes vessel efficiency regardless of power source.
Bergen-based Skarv, a joint venture formed by Peak CSL Group and Grieg Edge to develop sustainable short-sea shipping, specified inline ammonia-ready engines for the initial four 7,000 dwt ships, with the first ship due delivery in Q4 2025, followed by three more through 2026. The fifth vessel – due delivery in the second half of 2027 - will feature DF ammonia/MGO capability.
In all cases, vessel performance will count on integrated control and propulsion technology from Berg which is future-proofed to work with a full range of alternative marine fuels and other green energy sources.
Berg collaborated closely with Skarv and ship designer LMG Marin to devise a tailor-made, adaptable propulsion solution for the 108m length vessels. The system’s efficiency has already proved itself as ahead of fuel economy and emissions expectations in extensive model tests at Norway’s independent research organisation SINTEF.
“We have worked closely with LMG Marin, Berg and Shandong Huangdai Shipbuilding to secure efficiencies in every detail of these ships,” said Jan Øivind Svardal, CEO, Skarv. “As well as serving shipping’s decarbonisation agenda, we are confident that these high performance and adaptable carriers will attract charters from project cargo customers who expect the most cost efficient decarbonisation.”

Each ship will feature a single screw controllable pitch installation from Berg with a large propeller diameter and high system torque capability, optimised to match hull/power/speed - and in this case ice class - as well as thrusters. Berg’s control, power distribution and energy management system integrates main engine, battery and shore power sources to optimize vessel efficiency in all scenarios.
“The zero carbon carrier will be far more climate-friendly than what we see in Europe’s short-sea market today, with a very low fuel consumption,” said Svardal. “It is not what we imagine is the final climate solution for shipping, but it is a giant step in the right direction.”
Including electric motors with permanent magnet technology and run by Berg’s MPC800 Control System, the package provides continuous dynamic optimization of propeller rpm/pitch/vessel speed, in a setup also future-proof to integrate bigger batteries and fuel cells. It integrates dual DC-Hubs from The Switch, which control propulsion motors, batteries and the inverter for the main switchboard and deliver the variable speed capability to optimize genset energy use.
“The results from SINTEF verified how Berg technology future-proofs ships for efficiency independent of the power and fuel sources by reducing energy consumption dynamically and adaptively on an integrated basis,” said Mattias Hansson, Senior Global Sales Manager, Berg Propulsion. “We are therefore delighted that the owner has returned to place a fifth order in this innovative ship series."
“This is an outstanding example of what can be achieved by ship, main propulsion and electrical systems when a shipowner, a ship designer, a shipyard and an equipment and system integrator work together in the early design phase to prioritize performance and sustainability.”
