Faroe Islands-based MEST Shipyard has won a contract to construct an all-electric workboat for aquaculture company Bakkafrost
Based on a MEST 1508WB design, the catamaran-hulled workboat will support Bakkafrost’s ambitions to reduce its CO2 footprint from its Faroese operations by 50% by 2030.
“We have sustainability as one of our top priorities,” said Bakkafrost chief executive Regin Jakobsen in a press statement. “This is an obvious project for us to be part of, and we hope the project becomes a success, so that eco-friendly boats become a natural part of farming operations in the future,” he added. Bakkafrost operates some 60 workboats to support its salmon aquaculture business.
This all-electric workboat follows on a 109-m battery-hybrid wellboat ordered by Bakkafrost in 2020. The live fish carrier, with a capacity to carry 1,000 tonnes of salmon, is being built by Turkey’s Sefine Shipyard for delivery in 2022. Designed by Danish naval architectural firm Knud E Hansen, the live fish carrier, one of the largest of its type, will have a total tank capacity of 10,000 m3, composed of 7,000 m3 of seawater and 3,000 m3 of fresh water.
Propulsion and auxiliary power will be supplied by a combination of its five diesel engines and battery energy to optimise load and energy consumption and minimise greenhouse gas emissions. When docked, the vessel connects to shore power.
The Faroese Environment Agency was responsible for the tender process, which was organised as part of a larger project by The Nordic Council of Ministers and the government of the Faroe Islands. The goal of the project was to find power solutions for remote areas such as the Faroe Islands, which must produce and use their own green power solutions as they are not part of the European power supply system.
Workboats for the aquaculture industry were chosen as an appropriate pilot area to use green energy sources – and Bakkafrost agreed to participate on behalf of the industry.
“New ideas on how an aquaculture workboat can operate without using diesel have emerged. This is very valuable for the aquaculture industry,” said the environment agency in a press statement.
Added the agency, “ A part of the winning concept is that the boat operates throughout the day and lies still and is charged at night – when there is a lot of electrical energy available. Thus, the workboat helps to utilise wind and water energy better.”
Brunvoll has been selected to supply a battery package and electric motors for propulsion with hotel load supply and charge interface to shore connection. The integrated system design focuses on control philosophy and energy savings.
The Brunvoll system delivery consists of control systems, EMS, DC switchboards, variable frequency drives, electric motors and batteries.
“Brunvoll is proud to be the selected supplier for Bakkafrost’s first electric workboat, with a system that satisfies the shipowner’s requirements for modern, efficient and green operation of the vessel,” said Brunvoll Mar-El vice president sales and marketing Bjørn Svendsen.
