    Im not an expert by any means lol, but I'm sure Aotearoa does far more than just resupply our Antarctic bases and our ships. Others here I'm sure could enlighten us to other taskings we would do on her here, or on behalf of other Nations abroad.

    No about 40 minutes. Have to give her a fresh water wash down and secure all their perks :p Bloody expensive to transit though. Could buy a lot of squirt (navy rum) for that. :)

    It looks like the helideck has been decommissioned and is now which only.

    Eh what Rob? Thought it's supposed to be for lillypadding up to NH90 size.

    It might just be an optical illusion but that helipad looks a tad small for NH90 and what appears to be the nav light mast on the forward section of the helipad

    I have been looking for the dimensions of the helipad but cant find anything, but did compare it to the helipad on ADV Ocean Shield, which by online source say it is " A 21m x 21m helipad is provided that can accommodate a medium sized helicopter."

    Australian Defence Vessel (ADV) Ocean Shield - Naval Technology

    The only closet thing I can find is this:
    https://www.defence.govt.nz/assets/Uploads/2018-Dive-and-Hydrographic-Vessel.pdf

    "a helideck suitable for the Defence Force’s helicopters"
    And a NH90 has length of 19.5m at operational condition's Rotors turning, whats the minimum safe distance for a helicopter to land next to a solid object?

    Looks to me that it could be of the fold down variety with that boxy base and the guard rail also don't appear on the standard type ,but rather look more like the fold down type with netting and not intermediate rails. I would think that if the helipad was to be decommissioned standard railing would have been installed.

    I have found this this site which lists the helideck designed for a super puma, and with the specs listed for the Puma as length 18.7m (with rotors turning) its going to be tight

    It does seem odd that the helideck wasn't modified then for the size,weight of the NH90 while in Norway. Unless final modifications will be done here? Still it can operate our SH2 Seasprites if that's not the case.

    Looks hello capable to me; fold down netting and a jackstaff which folds flush into the deck. It is possible to land on with a clearance of a metre or ahead of the rotor arc although obviously the more the better

    Hey spoz, 1m rotor clearance on a ship? Are you saying it is technically possible or actually done? I would have thought that an unsafe practice in either civvy or military flying. 1m doesn't leave much fudge factor for changing gusts etc.

    Just done some googling this arvo on the Edda Fonn and sadly it in't NH90 capable. With the beam of the ship being 18m and the helipad only going slightly further I had already thought it would be unlikely but did come past some information on the Edda Fonn from prior to RNZN acquisition.

    Edda Fonn - Østensjø

    Her helipad is capable of 9.3 ton which would mean the AS332 Super Puma while through some guesstimation her helipad would only be around 19m though good news appears the big pole (light pole?) at the front does fold down. If a NH90 was loaded to full capacity then it could be done but wouldnt be advisable and would have to be a better then average pilot to do the job.

    It would be good to get minimum safe distance for the rotors. but it did get me thinking what’s the distance between the island on the Canberra’s as it’s only 32m wide I’m guessing the island would have to be 10/12m that’s giving 20m with MRH rotors 16.5m tip to tip.

    I imagine flight operations on HMNZS Edda Fonn will be stationary and come in from either side and not nose in then again I’ve never landed on a ship before so I’m guessing

    Yeah pretty sure you're right because if you spend long enough trawling the web for images you can find quite a few & I've seen 2 in the last few minutes that show different sections of the netting / railing that clearly are at different angles that indicate it's not solid & does indeed drop / fold down in sections as per standard heli-deck design.

    The 3 artists images posted in an RNZN article some months back show her with all her netting in the downward position & as pointed out by t68 the Govt's papers mention a heli-deck. The heli-deck has had a new paint job including all linings and the 'MAN' identifier added so there is clearly an intention to use it, even if only for VertRep. I do wonder about the NH-90 and they may only be used for VertRep but she'll land SH2G ok from what I can determine.

    I think it's a case of 'stand-down' on that one!

    How does a mission where a helicopter is used ,but no hanger is onboard, would Manawanui be deployed? With one under cover ,lashed to a deck ,say to a Pacific island or further under those circumstances? Or would it only be landing on Manuwanui if from another ship,Vertrep, or returning to a RNZAF from local coastal operations?
