Chilean shipyard Asenav has delivered the world’s first salmon processing vessel. The new commissioner Owurkan is the first vessel specifically designed to treat common aquaculture pests and diseases, such as sea lice.


The vessel was built at the Asenav shipyard in Valdivia, Chile, and delivered last year. The core processing machinery – a 300 cubic meter spiral tank – was built in the Netherlands and shipped by freighter. Upon arrival in Chile, the tank is hoisted directly onto the deck of the Owurkan for setting up.


the Owurkan is the result of more than six years of research and development. The owner and operator of the vessel, SalmoClinic, has developed an exclusive continuous bathing process which allows the controlled use of treatment products authorized for application in fish, without affecting the environment. Through a degradation process that removes residual organic compounds, the system prevents drugs from entering the sea.



“One of the essential characteristics of the ship is to reduce the use of pesticides or antiparasitics which today are used massively without adequate environmental control. This ship takes care of the products used and does not impact the environment”, explains Germán Schacht, Head of Business Development at Asenav. “It is the first ship in the world built for this specific purpose, and it is expected to revolutionize the industry.”


The ship is also equipped with a large reverse osmosis plant to produce up to 125 cubic meters per hour of fresh water needed for certain treatments, as well as a continuous filtration system to remove sea lice from the bath.


the Owurkan will operate primarily in salmon farming regions X and XI of Chile, depending on where its services are most needed. SalmoClinic expects five or more vessels will be needed to meet the needs of the Chilean market, and it could expand to other salmon-growing regions. The company is also considering a land-based version of its processing technology for use in hatcheries.
