PG Flow Solutions wellboat pump systems order

Ronjafisk 'Ronjafisk' will have a design adapted to Sølvtrans’ principle of sideways circulation in the cargo spaces

PG Flow Solutions will supply a seawater circulation pump and engine room pumps for a new wellboat.

Aas Mekaniske Verksted ordered the circulation pump, which is designed to ensure safe, efficient and humane transportation of fish, for wellboat Ronjafisk, under construction for Sølvtrans.

“We see that Aas Mekaniske and Sølvtrans put great emphasis on animal welfare, which translates into economic gain. This is one of the main reasons for why they have chosen to go with our pump systems,” said Roy Norum, CEO of PG Flow Solutions.

Continuous circulation

PG Flow Solutions’ large low-pressure seawater circulation pump is designed to ensure continuous seawater circulation in the vessel’s well to enable the transport of live fish, primarily salmon, from fish farms. The circulation system has a total capacity of 16,000 cubic metres of seawater per hour.

Constructed for efficiency and easy maintenance, the pumps can be operated by the vessel crew without support from an external service technician. This saves both time and cost for the vessel owner, and ensures animal welfare, said PG Flow Solutions.

A separate contract will see PG Flow Solutions supply all engine room pumps required for the main and auxiliary engines, plus generic pump requirements for operating the wellboat.


Designed for the transport, sorting and processing of fish, Ronjafisk will be 69.69m long with a design adapted to Sølvtrans’ principle of sideways circulation in the cargo spaces, as well as closed transport.

The wellboat has two cargo spaces totalling 2500 cubic metres - the equivalent of 375t of live fish.

Last year, PG Flow Solutions was awarded similar contracts for a sister vessel that Aas Mekaniske Verksted is building for Sølvtrans.
