Next week on 18th April the commissioning of the Skrunda into the Latvian Navy will take place in Riga, Latvia. Ordered in Sept 2008 and built at Abeking & Rasmussen shipyard in Lemwerder, Germany she is the first of a fleet of five patrol vessels, designed by the German yard. The four other vessels will be partly built in Lemwerder and at Riga Shipyard.

The patrol boat design has a length of 25.7 m, beam of 13.0 m and a draft of 2.7 m, and is derived from a well proven Abeking & Rasmussen  25m SWATH Pilot Boat design.

Skrundás twin propulsion units are installed in the SWATH lower hulls: MAN D 2842 engines rated 809kW at 2100 rpm, drive Servogear CPPs via Servogear reduction gearboxes. A speed of 21.4 kn was attained during trials.

The excellent seaworthiness of SWATH vessels was a principal factor in the decision of the Latvian Navy to adopt this new type of hull.
Not only are the ship’s movements effectively reduced and equate to that of a conventional monohull of three to four times its size, the crew will appreciate the low vibrations and noise levels well below 65dB(A).

This seaworthiness and a range of 1,000 nm will allow the new vessels to carry out offshore as well as costal duties. Their main duty is to monitor and control Latvian and EU territorial waters and exclusive economic zone (EEZ). From time to time they will also participate in international operations. The fender system of the pilot boats is retained and is well suited to all types of boarding operations.

Between the bows of the two hulls, there is provision to mount a Modular Mission Module that adheres to the dimensions a 20ft ISO container. Module payloads up to 6 tons may contain equipment for hydrographic survey, environmental protection, divers, MCM tasks or weapon systems.
