VESSEL REVIEW | Seigrunn – Norway's Seistar places salmon wellboat into service
A new large wellboat was recently handed over to Norwegian owner Seistar Holding. Designed by Salt Ship Design, Seigrunn will be used primarily for the transport of live salmon.
The newbuild is one of the largest wellboats in operation today, measuring 110 by 24.6 metres (360 by 80.7 feet) and with a design draught of 7.2 metres (24 feet), a depth of nine metres (30 feet), a deadweight of 12,000, and a total live transport capacity of 8,000 cubic metres (300,000 cubic feet). It is also equipped with specially designed cylindrical tanks to ensure the safe handling of fish.
Hybrid setup to help preserve fish health
The fish handling equipment includes three Wingtech fish counters, a Norwater reverse osmosis plant, six Palfinger Marine deck cranes, and other gear from MMC First Process.
The vessel is powered by a hybrid propulsion arrangement that includes four MAN 12V175D 1,800kW (2,400hp) main engines, two ABB 1,495kW electric motors, manoeuvring and side thrusters from Brunvoll, and a Corvus Orca Energy 1,491kWh battery pack. This configuration can deliver a service speed of 11 knots.
The integration of hybrid propulsion was in line with Seistar’s requirement for reduced emissions that could otherwise negatively affect the health and the quality of the fish as it is being transported. To further reduce its environmental impact, the vessel is fitted with a ballast water treatment system from Norwegian Greentech.
A Scania DI13 290kWe generator is available for emergency use. The electronics suite includes a Marine Technologies dynamic positioning system and Furuno radars.
Part of a growing live transport fleet
Accommodation is available for 16 crewmembers, and design work on the interior spaces was undertaken by Harmony Marine Solutions. Viking Life-Saving Equipment provided the rescue boat, the lifeboat, and their respective davits.
Seigrunn is one of two wellboats ordered by Seistar Holding in December 2020. Like the 70-metre Seifjell, which was handed over earlier this year, the larger Seigrunn is classed by DNV and designed by Salt Ship Design. Both vessels will be operated off Western Norway, transporting post smolt on behalf of local company the Lerøy Seafood Group.
