    New Danish Patrol Vessels

    Pics of the new Danish Patrol Vessels for Arctic Waters, i.e. Greenland and the Faeroes.


    Design of the new arctic patrol vessels; the foredeck holds a container position, so a Danish standard 76 mm Gun M/85 can easily be fitted.


    Aft there is a helo deck, but the vessels will have no hangar facilities to accomodate a helicopter on board, and a ramp for the landing craft.


    The first hull for the new arctic patrol vessels arrived last week at Karstensens Ship Yard in Skagen.

    Type:Arctic Patrol Vessel
    Units in Class:2
    Built:2005-2008
    Dimensions:
    Length:61.0 m
    Beam: 14.6 m
    Draught: 4.95 m
    Displacement:1,720 tons
    Complement:18 men (Accomodation for 43)
    Armament:2 - 12.7 mm Heavy Machine Guns
    Speed: 17 knots
    Range: 3.000 nautical miles

    Sustainability: 35 Days.
    Range: 3500 nm @ 15 kts.

    The hatch midships is where it would be stowed. Many navies are placing covers / hatches over their RIB Launching Areas. It serves a number of purposes:
    a. Helps reduce the RCS (Radar Cross Section) of the ship.
    b. Protects the crane and RIB from the marine environment, when it is not in use, thereby prolonging their life, especially the cranes.
    'Why have a crane exposed to one of the most corrosive environments 24/7, when you might only use it for 4-6 hrs a day!'

    Looks like it, the specifications say that it will be able to take a number of containers, I suppose like the UKRN HMS Clyde (the new Falklands Islands Patrol Vessel).

    It seems to be a popular Idea with many services, particularly considering the amount of self contained modules available in this size, Side Scan, Medical, Decompression etc.

    If its good enough for Spains Atlantic waters It should be perfect for ours too.

    Hvae to go with the Spanish option myself...seems to be a good allround concept.DElivery time would be my only concern. Given a 2010 date ..two PVs would be due to be out of service before aquiring replacements.

    Wonder would leasing something in the short term cover the short fall that will take place or would the PVs be made to carry on until acceptance of new vessels?

    If the cost of leasing was to eat into the shipbuilding budget, I think they'd just try to keep the PV's going until the new ships come online.

    Hmm dunno where as building a ship would be seen as a capital cost and covered proabbly in large proportion by EU funding......leasing would be seen as an operational cost and would probably run eat into operational budgets not funded by the EU....so it would seem your line of thought along keeping the PVs in service is valid....unless the case could be put forward on..well if some one doesen't come up with the money..we won't have ships to carry out patrols.

    I would think if a ship is in good shape at 30, there won't be much harm keeping the ship around a few more years. On the other hand, if a ship is in poor shape at 30, it should be discarded whether a ship has been built to replace it or not.

    Minister for defence is due to present proposals for the fleet replacement program to cabinet by the middle of this year, according to Cork FF TD John Dennehy.

    Assuming they have not been kicked out by then...

    This looks about right for Fishery Protection.

    Touch of irony about this

    "The first of the type, FPV Sulisker was launched in 1980 and decommissioned late 2005. The vessel is currently undergoing conversion to a luxury yacht in Lowestoft"..

    Sound familiar?

    multi-role

    Does the Naval Service have a requirement for a multi-role vessel that would combine capabilities such as emergency towing, diving support, pollution control, together with the usual patrol, surveillance and fishery protection jobs? Something along the lines of this Norwegian Coastguard ship:

    The replacement programme for Naval Service vessels is under active consideration. As a general guide, the objective would be to replace vessels after approximately 30 years service, on which basis, three ships will fall due for replacement in the next few years. These are the LE Emer, commissioned in 1978, LE Aoife, commissioned in 1979, and LE Aisling, commissioned in 1980. A departmental study group comprising civilian and Naval Service personnel was established in 2006 to examine and report on a vessel replacement programme having regard to imminent replacement requirements. The group has submitted its report, on foot of which I will bring proposals to the Government in the coming weeks. All going well, the tender process will commence within the next few months with the expectation of placing a contract for the first of three ships early in 2008.
    The cost of the three new ships ranges from €160 million at the lower end of the scale to €190 million at the upper end.

    Important words....

    "the first of three"

    Good to hear. Surprising, considering there is an election round the corner.

    This may be of interest, although in German it contains some data and a couple of computer generated photos of the B+V Guardian and Sentinel.
