Патрульні суда класу Ægir

The Ægir-class offshore patrol vessel is a class of two offshore patrol vessels serving in the Icelandic Coast Guard (ICG). They participated in the two latter Cod Wars. The vessels conduct patrols, search and rescue, fishery inspections, general law enforcement and counter-terrorism operations in the Icelandic exclusive economic zone and the waters of the surrounding territories, such as Greenland and Jan Mayen.

The concept for the Ægir-class OPV was based on the Icelandic Coast Guard experiences with ICGV Þór and ICGV Óðinn. Rear Admiral Pétur Sigurðsson, commander of the ICG, set forth a requirement for a ship larger than both Þór and Óðinn and more seaworthy. The vessels were also armoured for icebreaking.

Though of roughly the same design, the two ships are of different measurements. Ægir has a standard displacement of 1,146 tonnes (1,128 long tons) and 1,500 t (1,500 long tons) at full load. The ship measures 69.8 metres (229 ft 0 in) long with a beam of 10 m (32 ft 10 in) and a draught of 4.6 m (15 ft 1 in). Týr has a standard displacement of 1,233 t (1,214 long tons) and the same full load displacement as Ægir. Týr is 71.1 m (233 ft 3 in) long with the same remaining measurements as Ægir. The two ships are powered by two MAN 8L 40/54 diesel engines turning two shafts with Kamewa controllable pitch propellers rated at 9,800 kilowatts (13,200 hp). This gives the ships a maximum speed of 19 knots (35 km/h; 22 mph) for Ægir and 20 knots (37 km/h; 23 mph) for Týr with a range of 9,000 nautical miles (17,000 km; 10,000 mi) at 18 knots (33 km/h; 21 mph). The vessels have a 20-ton bollard-pulling winch and passive rolling tanks.
