SINKEX and f*ck the begrudgers"He is an enemy officer taken in battle and entitled to fair treatment."
"No, sir. He's a sergeant, and they don't deserve no respect at all, sir. I should know. They're cunning and artful, if they're any good. I wouldn't mind if he was an officer, sir. But sergeants are clever."

Originally posted by DeV View PostRequirements of NSDS Diving Tender (or at least a hired one)
Dynamic positioning / stern anchor
Crane (lifting up to 8t on and off vessel)
Carry up to 15 divers for up to 10 days
Carry 3/4 TEUs (the LARS unit is bigger than a TEU (3 of the 4 they make fit in a TEU, the dims provided could be when in operation) with the appropriate power.
Obviously this doesn't include any special counter-mine/counter-IED equipment (although 1 of the containers holds a ROV and SSS)
But it gives an identication of what would be required from the CPV for the new role (probably a different ROV and maybe less divers etc)

Originally posted by ancientmariner View PostSafety demands everything in it's place, and more crucially a space for everything. The p31 format is suitable, once the flight deck freeboard or height above water is not too restrictive. The CPV as laid out would not suit, so a new type vessel with clear decks aft and DP included , with necessary accommodations for divers/trainee divers, is needed. Perhaps this could all be part of an MRV with large daughter craft for working in shallower water.

30years ago today at #Rosyth Naval Base, two @RoyalNavy Peacock class vessels HMS Swift and HMS Swallow were handed over to the #irishnavy, where they have served proudly and with distinction as LÉ Ciara and LÉ Orla. #nostalgia #navy #defenceforces #fleetreplacement pic.twitter.com/315GZA9OPD

Both crews today, celebrating the 30th anniversary of commissioning of LÉ Orla #P41 and LÉ Ciara #P42. As per usual, both ships trying to outdo each other, but this time with cakes #bakeoff #ÓglaighnahÉireann #Strengthenthenation pic.twitter.com/2iT3jdxAe3

Naval Group has won the Belgium/Dutch minesweeper competition. Now we will have to see if France joins the project to replace their similar vessels.

Belgian/Dutch MCMV Competition Winner
Given the sheer size of the winning MCM 'Mothership' it would appear that expeditionary capacity is a priority.
https://www.belgium-naval-and-robotics.be/
In the region of 3,000 tonnes, this is not a contender for our upcoming CPV/Corvette/MCMV programme, as defined by the most recent Defence White Paper.

However a vessel derived from this, and associated designs, could produce a very capable OPV/ETV/Expeditionary MCMV.

The vessel type is interesting but needs more length with a beam nearing a 6:1 ratio, at 16.7 beam I would prefer a length of 100 meters. If we are talking about moving troops and equipment, and provided some in fleet logistics, we need to manage a decent payload, a 3000 tonner might not have enough payload. I think the proposed vessel will be pitched at 125 meters overall length.

I'm going to suprise myself here am and argue, in this case, for the possability of a smaller vessel.
Saab/Kokums MCMV 52 & 80
The corvettes need replacing, and in short order, on the heels of Eithne.
It's been argued that Orla & Ciara's modest draught are of great advantage when carrying out their fisheries protection duties. I don't doubt it.
I do though, find it difficult to gauge the value of that last marginal metre's clearance between say, the Peacocks and a Róisín class vessel. Because in terms of utility, endurance, and crew accomadation the consequence of that metre is a world of difference.
The Saab/Kokums MCMV 52 has a published draught of 2.4m, less than the Peacocks, and I can only assume that this increases progressively as the vessel's final design displacement grows. There appears to be potential for this vessel to evolve into quite a spiky little corvette, as evidenced in the following presentation, highlights at timestamp 1:05 - 5:10.

The principal operational question I'd have regarding this type of vessel is it's suitability for fisheries protection duties. I'm well aware that the prospect of stern-ramp RHIB operation does not meet universal acclaim in the Naval Service. In short, for the fisheries protection and general enforcement duties currently carried out by the Peacocks, which would be most suitable?
