Aas Mekaniske Verksted has chosen PG Flow Solutions to supply pump systems for seawater circulation to a wellboat the shipyard is building for Nova Sea Service.

The wellboat is of the yard’s own design, type AAS 3002 STDE-Hybrid, which is known for its low fuel consumption and associated low emissions to air. An ESS battery pack is used for peak shaving purposes during operation to reduce both the number of generators in operation and fuel consumption. The boat will also be equipped with a full exhaust gas cleaning system in line with IMO NOx Tier III requirements.

“Our seawater circulation pumps are both gentle with the fish and very energy efficient. They fit well with the wellboat’s environmental and fish welfare profile,” says Øyvind Berg, vice president of sales and marketing at PG Flow Solutions.

Pump and liquid handling specialist PG Flow Solutions will supply eight of the company’s large seawater circulation pumps that provide continuous seawater circulation in the boat’s well.

PG Flow Solutions’ seawater circulation pumps are highly efficient and developed to ensure the best possible fish welfare, which in turn translates into financial gains for the vessel operator. In addition, the crew on board can easily maintain the pumps without the support from an external service technician, which contributes towards keeping operating costs down.

“All our technology development has fish welfare at its heart. Both because it is the ethically right approach, but also because it provides financial gain for the wellboat operator and fish farmers,” says Øyvind Berg.

The pump systems will be delivered to Aas Mekaniske Verksted’s yard in Vestnes, Norway. PG Flow Solutions has not disclosed the value of the agreement.

The wellboat is newbuild number 206 from Aas Mekaniske Verksted. The ship will be built with diesel-electric propulsion and an ESS Battery plant for hybrid operation, as well as large onshore power capacity. The newbuild vessel will be 76.96 metres, 17.80 meters wide and depth moulded is 5.90 metres. The storage capacity is 3,000 cubic metres, equivalent to 450 tonnes of live fish.

The vessel will be delivered to Nova Sea Services in September 2021.

PG Flow Solutions provides proprietary solutions, systems and products for companies within aquaculture, maritime industries, energy sectors and land-based process industries. The company’s headquarters and manufacturing facility is located in Sande, Vestfold.
