Kustbevakningen (KBV), the coastguard organization of Sweden, has signed a contract for the construction and delivery of seven fast Patrol Vessels with Damen Shipyards.

These vessels, also referred to as the KBV 320 series will be 26,75 meters in length, built in carbon fiber composite, and will be able to reach cruising speeds of up to 25 knots. KBV will engage the new vessels in their rescue, environmental protection, salvage assistance, and coastal waters patrolling operations.

The KBV 320 series that Damen proposed exceeded the strict design criteria the coast guard had set. The Swedish government organization came with their initial design, reflecting the need for fuel efficiency, crew safety, and comfort, as well as operational flexibility.

The Damen team improved the design in terms of seakeeping, sailing comfort, and sustainability by lengthening the waterline forward and thus incorporating the capabilities of the ax bow.

A longer waterline allows vessels to maintain speed at lower resistance in the water, whereas the slim vertical bow seriously reduces slamming in the waves at high speed. The carbon fiber composite construction allows for a very lightweight vessel, further reducing fuel consumption.

The slipway in the stern allows for easy and quick launching and recovery of a RIB. Secondly, a sliding platform is installed for a Jet ski. A deck crane is installed for handling small cargo.

Full carbon fiber construction includes the superstructure. This strong composite allows for narrow window frames at the bridge, providing uncluttered views from the helm station, and increasing safety at high-speed operations. All seven patrol vessels will be propelled by three Volvo D13s and Volvo IPS 1050. including exhaust gas after treatment further reduces emissions.
