  • Norwegian Coastguard OPVs

    Here's an example of one of five hulls that the Norwegian Coastguard have built. They use two crews, 3 weeks on 3 weeks off, ship returns after 3 weeks, crews handover & straight back out to sea.



    On November 24, 2004 the Norwegian Coast Guard signed contract for five new patrol vessel of the ST-610 type. They will be delivered 12-14 months after the contract was signed. The vessels will be leased for 15 years. These purpose-built vessels will replace the five oldest vessels in the inner coast guard (No:indre kystvakt). They will provide significantly improved capabilities in all regards compared to the vessels they will replace. This includes seaworthiness (they are larger), towing capacity, fire fighting and environmental protection (collecting oil spills). The aft deck is for winch only.

    Specifications:
    Length: 47.2m
    Beam: 10.3m
    Displacement: 700 tonnes
    Speed: 17 knots
    Bollard pull: 20+ ton
    Engines: 2000kW (diesel electric), 1 bow thruster
    Gun: Probably 20mm

    Or a bigger version:


    Specifications:
    Displacement: 6500 tonnes
    Length: 103.7 m (340.2ft) overall
    89 m (292 ft) waterline
    Beam: 19.1 m (62.6 ft)
    Height: 8.3 m (27.2 ft)
    Draft: 6.5 m (21.3 ft)
    Power: 4 x 3390 kW BRG-8 diesel generators
    Propulsion: 2 x 5 MW Azipod electric motors
    Speed: 17.5 kn
    Range: ?
    Complement: ?
    Aircraft: Capacity for two helicopters;
    one Lynx carried initially, NH90 from 2007
    Radar: EADS TRS-3D /16 ES with IFF
    Gun: Bofors 57 mm, 12.7 mm
    Cost: 575 million NOK (80 million USD), radar and helicopter not included

    • Crewed along the same lines as the Rig support ships so? How big is the crew? Many countries coastguards and navies have bought or leased vessels such as this in recent years as Maritime Coastguard services in europe become more organised.

      • The medium sized verison (Norwegian CG)



        This appears to be somewhat in between the two previous versions

        Specifications:
        Displacement: 3121 ton
        Length: 83m
        Beam: 15.5m
        Max speed: 18.4kn
        Crew: 26
        Engines: Two Rolls-Royce Marine, 4000Kw each
        Propellers: Two; one swing up thruster 883Kw
        Crane: 15m/5 ton
        Built to operate the Nato Submarine Rescue System
        Gun: Bofors 40mm
        In service from January 2005

        KV Harstad is built as multipurpose-vessel, but optimised for emergency towing of large oil tankers (up to 200 000dwt), oil spill clean-up and fire fighting. The most common duty will be fishery inspection and search and rescue in Norways large exclusive economic zone. The steadily increasing traffic of large oil tankers along the Norwegian coast explains the need for this type of vessel.

        Some towing capability!

          B&H.. you mean Blohm & Voss?

          Don't think the PDF are willing to spend that much money on the largest singular capital expenditure in the DOD budget since the foundation of the State for the NS (circa €100 - 250 million for an MRV). We are far to small in comparison to the rest of the DF & seen as a threat by many to other arms of the PDF.

          • Are we back to the days of hoping for the scraps from the table of the DF budget? This attitude prevailed in the 60s and 70s and almost brought the NS to a premature end. Fact is there can be saving made in other areas as a direct result of having an MRV. How much did it cost to ship the Vehicles and equipment to Liberia for example?

            The Money is there. The rest of the DF budget could be considered "what if" equipment. Unlikely to be used in anger. Naval vessels of this type will be used. The value the Govt have got from the current fleet is example of this. Their penny pinching investment in the current fleet has served them well. Why can't they see that the more they invest, the better use will be made of the investment?

              Absolutely, but that is not what some dept's think!

              • Lets not forget that the Naval Service actualy generates income for the State in the form of fines from ilegal fishing by trawlers , maybe the money should go back into the Naval Service . Do I see a new incentive for the members of the Service . Just a crazy thought .
                Don't spit in my Bouillabaisse .

                • It would be the same as the Gardai looking for the money they gather for the government in the way of traffic fines back to invest in their own vehicles.

                    The money collected from fines wouldn't pay for a lot most fines are just a couple of thousand a few less and the very rare one in the tens thousands. At about twenty to thirty arrests a year that wouldn't go far. (not all arrests result in convictions and fines)

                      • Looks a lot like one of those Oil Rig supply ship/ anchor handling tugs in hull form. Does it have any sort of bollard pull capacity?

                          It is capable of towing, but as yet I have found any info on her bollard pull.

                          The attached pic, is the stretched version (95m) of the 'Sarah Baartman' (83m) from Damen yards. No example built yet



                          Here is the 68m version

                          • A question that someone may be able to help me with?

                            I was reading an interview in August issue of Jane's IDR with the CEO of Schelde Shipbuilding, he was talking about a new large OPV they planned, approx. 2800 tonnes, and he used a quote that I read in An Cosantoir "steel is relatively cheap and the air inside it is free"! Is this a nautical term or just a coincidence that a Naval Service officer would use the same quote?

                            He also mentioned in the same quote, something that is probably pretty obvious to you naval types, but to this landlubber was interesting "longer vessels can smaller engines" for the same performance and presumably lower cost.

                            Just thought I'd ask.

                              • Obviously a longer vessel of steel costs more than a shorter vessel of steel. Having said that, similar sized warships costs differently. For example a smaller warship with more weapons can cost much more than a larger warship without many weapons. For example, an Irish Roisin class 78 meter OPV cost around 30 million Euros, whereas an Israeli Saar V class 85 meter corvette cost 200 million Euros. Why the 170 million Euros difference between the Israeli corvette and the Irish OPV? Its not the price of steel. The steel for the Irish ship maybe 15 million Euros whereas the steel for the Israeli ship maybe 16 million Euros. The air inside a steel ship is free!

                                The longer ship with the same beam and engine plant will go faster than a shorter ship. Therefore, logic maintains a shorter ship with the same beam will need a more powerful engine plant to match the speed of the larger ship. Obviously a more powerful engine plant costs more than a less powerful engine plant.
