New conversion contract for Fiskerstrand Verft AS within battery technology, “Karlsøyfjord”

Fiskerstrand Verft AS has signed contract with Boreal to convert MF “Karlsøyfjord” from the current LNG propulsion system to an all-electric propulsion system with battery as power source.

“Karlsøyfjord” is scheduled to arrive at the shipyard at the turn of the year. The ferry is to be upgraded according to DNV-GL’s “battery power” notation, where the batteries are defined as the vessel’s primary energy source in a new and modern battery-electric propulsion system.

As part of the redevelopment, the cooling systems, ventilation system and fire/safety systems will also be upgraded. Existing LNG engines are to be removed, and new modern generators, including a purification system, are to be installed to ensure redundancy in the systems as a secondary energy source.  “Karlsøyfjord” was also at the yard in autumn 2020 to adapt the universal design further.

Siemens has been selected as system supplier and will deliver BlueDrive PlusC boards, Energy Management System (EMS), charging systems and batteries in connection with the upgrade. Acel will be responsible for all electrical installation on board.

Fiskerstrand Verft AS is very satisfied with the trust Boreal shows when they choose to place the contract at us. This is historically one of the largest contracts the yard has signed in the field of conversion of sailing vessels and shows that the competence and experience the yard has built up in recent years in the field of environment and zero-emission technology, through several similar conversions, gives shipping companies peace of mind when they choose Fiskerstrand Verft AS.

The contract is worth more than NOK 140 million.
– Our goal is to be a leader in environmentally friendly ferry operations. We have had a long and good collaboration with Fiskerstrand, and we are now looking forward to working together on this assignment, which will both provide significant savings for the environment and increased quality for our travelers, says Group Manager Kjetil Førsvoll in Boreal.  2021
