An innovative live fish carrier Aqua Tromøy (yard no. NB SC 75/1 or Crist B75) built for the Norwegian owners Artic Shipping AS (Artic Group) has been recently delivered from Gdynia based Crist SA yard. The vessel left the yard and the port of Gdynia on September 13, 2018. Crist yard launched and floated out Aqua Tromøy on January 21, 2018. Following outfitting the ship was undergoing its first sea trials at the end of second decade of August.
The modern, highly automated and versatile vessel, with diesel-electric propulsion, will be most probably used in the North Sea and/or in the northern parts of Atlantic and Pacific Oceans.
The contract won by Crist for fully outfitted multipurpose live fish carrier of the SC 75 design was announced in October 2016. At that time the delivery was said to be scheduled for Q4 2017.
An order for the second vessel of the same design – SC 75 (newbuilding no. NB SC 75/2 or Crist B75/2), was acquired in March 2017. The second unit, to be named Aqua Kvaløy was about to be delivered (according to initially released information) in mid-2018. More recent known reports were saying of August 2018.
Meanwhile, the two ships on order have been transferred to the prospective fleet of newly established DESS Aquaculture Shipping, which is to become an operator of the two sister vessels. DESS, is a joint venture of Marine Harvest and Deep Sea Supply. According to some sources, the technical and crew management responsibilities for Aqua Tromøy was about to be assumed by Stan Shipping Agency Ltd. of Gdańsk, Poland.
The design comes from Seacon AS, a Norwegian consulting naval architects / ship designers specializing in fishing and fish farming industry vessels, but has been developed in cooperation with Artic Group and Havyard MMC of Fosnavåg. The NB SC 75/1 newbuilding is designed and built according to the rules and under supervision of DNV GL.
The SC 75 series has been designed to offer a less expensive wellboat (live fish carrier) without compromising the quality of design, comfort, environment and fish processing. Simpler concept, different thinking and other ways to put together the boat and the fishing package makes the boat cheaper overall. The equipment and the quality in general are on par with or better one, similar boats – the designers assure.
Each of the vessels will be equipped with two tanks for live salmon delivery with a total capacity of 3000 m³, which may also be used for de-licing either with freshwater or with hydrogen peroxide.
