Dat kan kloppen!  Noorwegen heeft sinds 2009 - 2010 drie OPV's in dienst genomen. Die gebaseerd zijn op een Noordzee trawler, om zodoende de snelheid en brandstof verbruik te optimaliseren.
De KV Sortland, KV Bergen en KV Barentshav meten normaliter ca. 3.100 ton en maximaal 4.025 ton.  Deze OPV's zijn 93 meter over alles, en zijn 16,60 meter breed. 
Om kosten te besparen, heeft men deze schepen voorzien van een bi-fuel voortstuwing met diesel + LNG elektrisch.  Op gas elektrische aandrijving haalt men 15,5 kts (knopen); mechanisch maximaal 18 kts en in de hybride modus haalt men maximaal 20 knopen.
Deze schepen zijn ook nog eens duurzaam: ze stoten 25% minder CO2 uit en 90% minder stikstof oxide.  Plus ze hebben ca. 25% lagere brandstofkosten.  Deze OPV's worden bemand door 40 koppen.

Als ik een OPV ontwerp zie ..denk ik altijd ..waar is het visnet ? :devil:

Het is geen schoonheid, wel functioneel met de containers op het achterdek.

DSEI 2013: Babcock prepares to launch first OPV for Ireland, lay keel for second

The Irish Naval Service's two new 90 m offshore patrol vessels (OPVs) will achieve key milestones in November when Babcock Marine launches the first of class and stages a keel laying ceremony for the second ship.

Lead ship LÈ Samuel Beckett will enter the water at the shipbuilder's Appledore yard in southern England on 3 November, a Babcock representative told IHS Jane's at the DSEI exhibition on 11 September. This will be followed by a keel laying ceremony for the second ship on 4 November.

Under current scheduling, LÈ Samuel Beckett is on track to be handed over to the Irish Naval Service in February 2014, with delivery of the second ship expected in February 2015, Babcock said.

The two OPVs are being built under a EUR99 million (USD131.4 million) contract awarded to Babcock in October 2010 under Ireland's Naval Service Patrol Vessel Replacement programme. They will replace the navy's three ageing 65 m P21-class OPVs, which were built by Verolme in Cork in the second half of the 1970s and entered service between 1978 and 1980.

The ships are based on STX Marine's PV 90 design, which is a lengthened variant of the PV 80 design employed for the two 1,700-ton Roisin-class OPVs built by Appledore Shipbuilders for the INS between 1998 and 2001.

Displacing around 1,933 tonnes, the OPVs will be fitted with a diesel-electric propulsion system that provide a top speed of 23 kt, cruise speed of 15 kt, and range of up to 6,000 n miles. Endurance is 21 days. Accommodation is provided for a complement of 44 crew, plus 10 trainees.

Armament - which is being procured under a separate contract worth EUR7.8 million - consists of an Oto Melara 76 mm/62 gun, two 20 mm cannons, and four general purpose machine guns (two 12.7 mm and two 7.62 mm).

A helicopter in-flight refuelling facility and stowage for three 20 ft containers will be provided on the aft deck. Although this deck is not intended to provide a landing pad for helicopters, the operation of unmanned aerial vehicles may be considered in the future.

The vessels are designed to provide an operational capability for up to 30 years of service in their main area of operation in the North Atlantic, out to the 200 n mile limit of Ireland's Exclusive Economic Zone and beyond. Patrol duties will include fishery protection, search and rescue, maritime protection, drug interdiction, anti-pollution, and maritime security missions.

An option for a third OPV may be exercised at a later date.
