Swedish owner Erik Thun Group has chosen Berg Propulsion’s dynamic drive technology to enhance efficiency across its fleet of 10 newbuildings
The decision to install Berg Propulsion dynamic drive was taken after pilot installations exceeded expectations in terms of energy efficiency gains, noted Erik Thun when it confirmed its decision, citing fuel savings of 10% and up to 20% in specific operational conditions.
Dynamic drive is an adaptive software that optimises thrust and fuel consumption and is offered as part of Berg Propulsion’s MPC 800 control system: the software dynamically identifies the most energy-efficient pitch and rpm settings for the propeller to maintain the required speed.
As part of its ongoing fleet renewal strategy, Erik Thun expanded the newbuild programme with Shipsveerf Ferus Smit BV. The programme includes four 5,100-dwt Troll-Max dry cargo vessels and six 7,999-dwt coastal Eco Tankers.
Tanker deliveries began earlier this year, and all 10 vessels are scheduled to be in service by 2026. Each of the 10 ships will feature Berg’s comprehensive main propulsion systems and energy optimising control technology. Dynamic drive was included after successful trials on Snow Crystal, Nordic Crystal, and Baltic Crystal.
Erik Thun technical project manager Ola Persson stated that data showed dynamic drive could provide an average fuel consumption reduction of 10%, with a potential increase to 20% in specific operational conditions.
Berg Propulsion general manager Europe and Americas Jorgen Karlsson emphasised the user-friendly interface of dynamic drive in that it simplifies operations, allowing crew members to set limits more easily and ensures consistent fuel-efficient vessel operation across operational modes.
Eric Thun initially conducted a successful trial of the solution on the newbuilding bulk carrier Snow Crystal – a modern, energy-efficient ship operating on Lake Vänern in Sweden.
The positive results led it to choose the solution for Nordic Crystal and Baltic Crystal, with specifications modified to include ’floating frequency’ capabilities.
Erik Thun deputy managing director Henrik Källsson said, “Decarbonisation is a key driver for our operations and maximising efficiency is a central requirement for reducing carbon intensity, whether we are talking about current fuels or the new generation of higher-cost alternatives. Dynamic drive is delivering a practical solution that helps a ship’s crew and its owner achieve greener operations.”
