Those of you who follow the naval news around the world know that the RSwN are planning to replace it's ageing support ships (HSwMS Trossö and HSwMS Visborg) with a more capable ship. The concept was named L10. Thus lots of studies the ships has never realised due lack of funding and an unclear picture of the ship must be capable of. Here is "Global Securites article about it,HERE.

how would you design her?

Some specs

Size: 120m maximum, 6m draught maximum, 20m beam
Helicopter deck able to land a chinook, or handle up to 4x NH90. Hangar for at least 2x A109 or 1x NH90
Accomodate onboard staff of 60 pax or 100 soldiers/ sailorrs.
4x RHIBs or 2x CB90
20x standard containers
able to do a side and a stern refueling
small crew, 40 pax maximum (exempt hosptial, staff and aircrews)
1x room with up to 4x intensive care patients.

very cheap.

Aha, the Philippines has a similar requirement for a support ship (Strategic Sealift Vessel in Philippine Navy terminology), however the specifications you gave are the minimum in the Strategic Sealift Vessel requirement (see http://maxdefense.blogspot.com/2013/08/ ... ppine.html). But since the Philippine Navy has a similar boat to the CB90, called the Multi-Purpose Attack Craft (MPAC), and the SSV may accomodate the MPAC, the smaller designs submitted in the PN SSV requirement could do.

BTW, here is the MPAC, the Philippine version of the CB90:

I think something along these lines:

I know I'm not good at ship design so I'm pretty sure there are quite a few flaws in there. If someone more knowledgeable would point them out and suggests ways to fix them, I'd be happy to.
And, in case you're wondering, here's the inspiration.

I dare to say, that it's somewhat ugly ship, but certainly an interesting (and drawn in excellent manner) concept. :)
Is the hangar in the superstructure? It looks that it will be bit tight height-wise.

Thanks, eswube. The hangar can be located either in the superstructure between the stacks or under the helo deck (or even both, what do I know? :D), there should be enough room for a folded NH90.

I like that one, maybe not that nice looking but still... can take to the north point and back with heavy working style. ;)

As promised i would work on something,

I did cheat a little ( bigger then u wanted ) but i cant fit all of that in to a small ship
I resized it to 144 m, still a WIP. more will follow later ( after weekend )

haha, this is funny! sooo many of the common misconceptions :P

- the ulstein X-bow is not more modern. it is different. it trades speed in bad weather for an lower top speed and less comfort. adapting it is a choice, not a need.
- the other bow you list is looking modern, but this is only because of the streamlined part on top. other then that, the bow is EXACTLY the same as that as the enforcer style bow.
- the bow on whyme's design is actually an example of another modern bow.
- the enforcer type ship has exactly the thruster you are describing: protected (shrouded) propeller with rotating pods, in this case electrically driven azimuth thrusters, an setup that offers advantages of both the fixed and the azipod propulsion
- it is not a must to have pods, especially not when build to civilian standards. efficiency might be more important than manouvrability, and especially with ships this size bow thrusters can do the trick as well. if needed, stern thrusters can be added as well, which makes the ship just as manouvrable as an podded design, for the same or lower cost and less technical difficulties.
- the enforcer design is listed as WIP, so I suppoe an crane will be added
- you have listed the walkway as replenishment system.

- the weapon systems have very little impact on the weight of the absalon, and even less on the volume. yep, you might be able to carry some more cargo, but to really make an difference you are actually designing a new ship, much more desing work then you seem to suggest.

- I wonder why you ask for an crane to be stealthied. that takes a lot of effort and has very little effect. as I think this ship will not be in the first line of combat, I would doubt if that effort would be worth it.

on other points, I can understand or agree with what you are saying ;)
