    I thought it's just a yard now owned by Babcock Marine that services RN vessels.
    you could be right i was thinking of babcock myself but i thought they were still building at that yard

    • I believe the Appledore part of Babcock is earmarked to build a module of the new RN Carriers.

      • so you could rule it in then as one of the yards. so when this ship goes ahead then id say we are looking at ENGLAND FRANCE OR HOLLAND for the new ship

        • I've always been of the opinion we should look at the stanflex system from Denmark as a template.
          Building the vessels in Denmark could get better cost support from EU.

          Replace OPV's on a one by one basis with the Danish Rasmussen class.

          with a fleet aim of 6
          The other potential vessel for me would be Canadas Kingston class, but that needs further investigation.

          The attraction of the Kinston is possible adaption as multi purpose emergency tugs for towage with DP for SOPEP etc.

          What I mean by a simplified version of the Danish OPV is we dont need the Ice strengthning, reducing costs.
          We dont need - currently - anything like the full weapons and sensor fit - but the flex concept allows for reasonable refit redundancy.

          The other thing I would do with the NS is develop an organic UAV capability.
          Rotary - maybe, more likley fixed wing UAV from ship platform.

          • A fine ship of course, But just too short for our requirements. The increased length has been identified as an important factor for being able to operate effectively in the Atlantic conditions we Face. Something to do with wave frequency, and the ship goung through waves, rather than over them. Keep in mind that the smaller vessels,of the Danish fleet will spend much of their time in the relatively sheltered(compared to the atlantic) area of Skaggerak, Kattegat and the Baltic, which is prone to Ice for much of the winter months. It would be akin to Inshore work, with risk of Ice. The Canadians would have similar areas.
            The Flex concept is definitely a good idea though

            • I agree, the Danish flex family is a starter point, and their vessels do spend a lot of time in the North Sea and Greenland areas.

              In terms of length, stretching a vessel is not technicaly difficult - quite common.
              It depends on framing of the vessel really.
              A stretched version - say 24 ft. bay in the proven danish design would allow for a lot of modification and enhancement without full design cost.
              For starters, as a suggestion - additional thrusters to give DP capability.
              Then by containerisation one could provide dive support, ODAS/Nav marker deployment, MCM etc.

              It ties in with my views on the EPV requirements, and the smaller types in the Flex family could be seen as future or replacement vessels for Coastguard and Customs cutters.

              However, this would take long term planning from Government (any Government) so that in itself is a hinderance when we look at succesive administrations attitudes to maritime affairs (I am stopping now - rant verging)

              Denmark is a coastal nation, near enough in size in terms of population, budget and requirements.
              As we would not be going for the Rambo weapons fit, that offsets costs.

              Whatever benefits they have in terms of NATO membership in savings, we could probably replicate through EU funding, at least partially.

              I'd just like to give my reasons in favor of Flex.
              The Flex system is fitted with the Danish concept of patrol, as opposed to the MEKO system of full war fighting ships with associated costs, and no disrespect to MEKO fans, this concept -excellent for what it does - has a more narrow focus.

              The Flex system also has - for want of a better word - a plug and play weapons fit, that would allow for future inclusion if ever needed during the next 25 - 30 years

              A RAM/CIWS capability would be prudent and pragmatic if, for example, UN operations faced a potential threat from something like silkworm, AS missiles are becoming more common, an Israeli ship was hit by Hezbulah, so it is even at a sub nation state consideration at this point.

              In terms of training in use, computer simulation is becoming increasingly sophisticated.

              With containerisation missiles are becoming increasingly less reliant on shipboard maintainence - return for repair with specialist is - for Ireland - the best short term solution.
              And we dont need a full weapons fit to provide training in maintainence - a single model for trainingrefresher and perhaps a second for operational maintainence would be, IMO, a realistic medium term aim.

              • I agree completely with all that you said, however I think it is more practical for an EPV type vessel rather than an OPV one, for now anyway.
                The time It would take to bring the mandarins round to that way of thinking would delay urgent builds, and return us to where the NS was in 1970.

                • Absolutly, the EPV to replace Eithne needs to be the priority - and I hope it is an Absalon, standardised modular type that could lead to a cohesive maritime security policy, improve crew conditions and training - and give better value for the tax payer.

                  I would hate to see the NS been put on the back seat again.

                    lads i think we might be jumping ahead of ourselves here on the eithne thing lets retire emer first . theres another 10 plus years in that flag ship yet

                      The most costly part of the "Holland" OPV though is its integrated mast I understand. What it costs would be similar to what we expect to pay for a whole ship..
                      The EPV is an Enforcer version, but has no well deck.
                      Size: 27,800t
                      Costs: €363,6 million.

                      Costs of the OPV: €467,8 million for 4 (in 2007 prices). The Integrated Masts (4 of them)account for €125 million of the amount.

                      • New NL navy OPV launched
                        Koningin Beatrix heeft vandaag het patrouilleschip Holland gedoopt. Het Ocean Going Patrol Vessel is de eerste in een reeks van 4 nieuwe patrouilleschepen vo...


                        Its in Dutch, but basically when the minister is talking he says its a general patrol ship, with tasks such as anti piracy and people smuggling in mind - and though the max speed is 20kts her outriders and if embarked, helicoptor - compensate for this

                        • If you listen to dutch for long enough, it begins to sound like engrish.

                          That sensor mast is the key though. Basically you have a lightweight aegis, on an OPV platform.

                          • Yep.

                            That's so you have a perfect view of that missile coming directly at you and that you can't stop because of a lack of armament.

                            • Navy Takes Delivery of Offshore Patrol Vessel


                              (Source: New Zealand Defence Force; issued February 18, 2010)

                              Chief of Navy, Rear-Admiral Tony Parr and Ministry of Defence Project Director Gary Collier formally accepted the Offshore Patrol Vessel, HMNZS OTAGO, into the Royal New Zealand Navy at a ceremony in Melbourne today.

                              “OTAGO and her sister ship WELLINGTON will deliver the Navy substantial new capability to undertake Exclusive Economic Zone patrols, surveillance and military operations around New Zealand, the southern ocean and the Pacific,” said Admiral Parr.

                              “OTAGO and WELLINGTON have the capability to operate further offshore than our existing patrol vessels, stay at sea longer, and conduct more challenging operations – using their helicopter capability, sea-boats and embarked forces.”

                              Rear-Admiral Parr said it was no secret the Navy had waited longer than planned to get the ships.

                              “The Navy is now focused on getting these ships into service to do the jobs they were designed for. We’re confident the issues around the ships’ weight, which have contributed to delays in acceptance, can be managed so they can successfully carry out their missions. We wouldn’t have accepted the ships otherwise.”

                              HMNZS OTAGO is the sixth ship in the Project Protector fleet. Acceptance of OPV WELLINGTON into naval service is expected in April. Admiral Parr said that with the delivery of OTAGO and WELLINGTON the Navy will be operating a fleet of 12 modern, hi-tech and highly capable ships.

                              “With the completion of Project Protector the Navy can deliver the full range of maritime military capability from combat and security missions to peacekeeping, border patrol and humanitarian and disaster relief,” said Admiral Parr.

                              The delivery crew of HMNZS OTAGO will now undertake safety and operational preparations for her voyage to New Zealand. We expect OTAGO to arrive at Devonport Naval Base toward the end of March where she will be welcomed with appropriate ceremony.”
