H&W Appledore: All Survey, OPV and Patrol vessels
Barrow: All Subs
Cammell Laird: RFA refit work
Also, I am not entirely convinced about another RRS SDA for the MROSS for a couple of
reasons. Rolls Royce sold its commercial marine business to Kongsberg in 2018. Not a deal breaker but perhaps a bit more problematic due to the intended use of the vessel. Also, the RRS SDA was specifically designed for Antarctic research work. The ice breaker facility and large accommodation allocation really isn’t needed for the MROSS. The forward facing hanger is small, can a Wildcat even fit? Looks tight. The design could be adapted but adapting to RN standards could be expensive.
An adapted BMT design built at Appledore seems just as likely IMO. Something derived from Salvas perhaps,
https://www.bmt.org/projects/project/33 ... liary-ship
We have two separate MROSS orders. The first one is going to be a commercial design, being bought off the shelf. It's more likely to be something like the Salvas utility auxiliary ship you listed or platform supply vessel (PSV) or diving support vessel (DSV). Whereas the second one is going to be designed and purpose-built.
I can't find the reference to the relevant article, but I read that the first one will be smaller and would cover North Sea and irish Sea, whilst the second one would be intended more for deep ocean work, presumably for North Atlantic and Arctic Oceans and Greenland / Barents Seas.
I don't think we need a dedicated Icebreaker with one of the higher Polar Classes (PC) ratings. We are not an Arctic Power per se, but we do have an interest in keeping an eye on the seabed with telecoms cables vital to the security and finances of the UK. With HMS Protector and RRS Sir David Attenborough both based mainly in the Antartic, I think it does UK no harm if it has one vessel that it can safely deploy to the Arctic, even in northern winter.
Both HMS Protector and RRS Sir David Attenborough have similar sized crew complement of around 88 and accomodation for 100/90. The latter ship includes 60 scientists for research purposes. It may be for the larger ocean going MROSS role, the ship might need less accomodation and more room for sensors and diving equipment, helicopers and USuV's etc.
So I am not averse for a yard like Cammell Laird to take the lead in building the second MROSS, adapting the RRS Sir David Attenborough design, and then subequently going on to build an adaptation of that design to eventuallty replace HMS Protector in the late 2020; / early 2030's.

Re: Multi-Role Ocean Surveillance Ships
I think it’s a given that the two MROSS will replace the remaining Echo and HMS Scott. The later has the ability to operate in Ice but is not an ice breaker.
Given however that the Artic is going to be a region of increased interest, perhaps another commercial conversion like HMS Protector would be the best approach for the first MROSS. This would then give the ability to always perform Survey operations in this and the South Atlantic.
The second vessel can the be more specialist like HMS Scott is.

Re: Multi-Role Ocean Surveillance Ships
The trouble with Scott is it's too specialised. The most important requirement for MROSS is going to be surveying the seabed but also being able to operate large UUVs for a sustained period.Repulse wrote: ↑18 Nov 2022, 09:04 I think it’s a given that the two MROSS will replace the remaining Echo and HMS Scott.

Russia's getting increasingly meddlesome in the high north and as as more ice melts the situation is going to get worse. So some ability to operate in ice probably not a bad thing.
Re: Multi-Role Ocean Surveillance Ships
I really don't think Russia is going to be in any fit state to do much beyond its own borders, once the war in Ukraine is finally done with.
The bulk of their most capable, professional military people, which isn't saying much, has been hollowed out severely over the last 8mths, and its only going to get worse for them.
In terms of conventional threat, Russia is done, for the next decade at least.

Re: Multi-Role Ocean Surveillance Ships
Yes it is.
I'm concerned about the unconventional threats, one of which is attacking infrastructure, and that seems a more likely outlet for Russian aggression now.

If Putin survives this he's going to be in full-on hybrid/unconventional mode. And his most credible military assets - the submarine service - have hardly been used in Ukraine.
We're really going to need MROSS.

Re: Multi-Role Ocean Surveillance Ships
Maybe look at the design of the new RCN Arctic Patrol Vessels they are currently building and use this as the core to their design?
Re: Multi-Role Ocean Surveillance Ships
Sorry if I have missed an earlier post but the first ship has been selected and should in service by March next year. The second ship has not yet been selected but could be a new
build. I'm trying to remember the name of the first one - two words both beginning with S.

Re: Multi-Role Ocean Surveillance Ships
The Canadian Arctic patrol vessels look good, as do the new Norwegian arctic patrol ships below.
While they do look good, do these bespoke designs offer much of an advantage over the many offshore construction vessels out there ?

Could these new plans to enhance our shared security include a Kongsberg design for the second MROSS like RRS SDA?

Re: Multi-Role Ocean Surveillance Ships
It looks like a very sensible purchase. 9 years old, massive amount of crew space, decent deck space, heli deck, massive crane, moon pool, dynamic positioning...lets just buy another...

Re: Multi-Role Ocean Surveillance Ships
At the risk of a stupid question, why is the heli-pad in front of the bridge on such ships, rather than behind?
I am presuming it is a question of balance when the aft crane is in use and/or for improved seakeeping??

Because the money maker on these ships is the work deck on the back. They're the pickup trucks off the offshore industry, so they want the bed to be as big a possible.

Will be interesting though to see what changes they do - they may chose to move the helipad aft, like they did on HMS Protector.shark bait wrote: ↑17 Jan 2023, 19:35Because the money maker on these ships is the work deck on the back.

Apart from UUVs, I wonder what else they will be looking to operate if they are their basically to counter Russian subs / UUVs messing with stuff.

Isn’t it amazing how fast procurement can happen when the DS manages to focus minds.
Hopefully this pragmatic decisiveness continues onto other projects.
