News Release

Following the official handover to operator Sølvtrans in Skateflukaia, Ålesund at the end of March, the Ronja Princess has now successfully completed sea trials and started work in Norwegian waters.

She’s a wellboat transporting live fish, mainly salmon and trout. Designed and built by Aas Mek. Verksted on the AAS 3002 ST platform, her capacity is 3,000m3 split between two tanks. This equates to around 450 tonnes of fish.

Her crew of 12 have separate cabins, each with en-suite facilities. Also on board is a galley, a coffee bar by the working area, a TV lounge and an exercise room.

Supplying the propulsion is a Yanmar 6EY26W rated at 1,920 kW at 750 RPM. This is connected to a Brunvoll Volda gear and propeller system. Brunvoll also provided three side propellers, one forward and two aft.

It’s all controlled centrally from four operator positions in the wheelhouse. As well as propulsion, the fish welfare and hygiene operations are managed from there, including tasks such as monitoring, UV water treatment and lice removal.

Karina Djupvik from Aas Mek. Verksted says, “We’ve been using Yanmar engines since 2019, always after close dialogue with the owners. On this occasion it was a fairly straight-forward installation and integration, all the components are robust and simple. When choosing an engine we look for a sustainable solution for our propulsion as well as state-of-the-art technology which complies with current rules and regulations. Also the solution has to be cost effective.”
