A Large Rig Carrying Ship

yes i was very wrong, take for example an offshore structure based in the northsea of around 1000T
just it costs its about $3-2,000,000 dollers for mobilisation/de-mobilisation
and around $600,000 a day onsite these are just rough figures, and can vairy masivly depending on what its lifting how its lifting, location ECT ECT ECT

yeah that's more like it. $550-750 depending on market and, as you say, what work is aftually being done.
Mob usually 3-7 days and demob 2-4 days at a slightly lesser rate so your costs are bang-on there.
Seen the new monster from Allseas, the Pieter Schelte? Single lift catamaran, 47,000te lifting capacity! :-0

The heerema Thialf is around $100,000 per day, give or take depending on what its doing/lifting/and its location
The Thialf and Saipem s7000 (the only two twin 7000te HLV's operational at the moment) are both WAY more than $100k/day!Paddy_N_Murphy said:

IMHO
Delivery for end of '13 and operational for summer campaigns in 2015? Maybe Optimistic.
True 47000te lifting capcity? Optimistic too.
The vessel is a clever concept and they are pushing it very aggressively. Not surprising given the cash they're throwing at it.
Yeah, I know what you're saying. They are definitely building a dumb barge to do the HLV>quayside transfer.
I think are pretty clear advantages for the decommissioning - a bare minimum of separations work offshore and the vessel would be in the field for a much shorter time period than doing reverse installation.
It all depends how they contract the work - I would imagine they will offer contracts on a lump-sum basis (with huge weather windows) and guarantee to remove the topsides. If SLV doesn't work they will resort to reverse-install.

Just had a few beers with a commercial guy who is well known in the diving / dsv world out here that a few of you probably know, (long term Asia, American ex diver) and the day rates for some of these things on short charter will make your balls ache, that dock wise dayrate is north of anything bmentioned here...
+\- beer & bs factor on both parts....

Also my companies very own:
Main Hoist Lifting Height
95 m (312 ft) above work deck for each crane. Lowering depth of auxiliary hoists 460 m (1,500 ft) below work deck at minimum radius.
Main Hoist Plumbing Depth
Lowering depth of main hoist at minimum radius with 3,500 t is 307 meters below heel point and with 2,990 t, 351 meters below heel point. Heel point is 24.4 meters (80 ft) above work deck.
Tandem Lift
Main hoist 14,200 t (15,600 sht) at 31.2 meters (102 ft) radius (subject to stability calculations).

the saipem 7000 record was the BP Valhall 11,600 tonnes
and which boss? we have a few
She lifted over 12,000 tonnes with the Sabratha topsides in Libya. The difference being that she was on DP for the BP lift, on her anchor spread for the lift in Libya. However, the Sabratha lift strained the old girl; some unhealthy cracks appeared in the void spaces forward following that lift!and which boss? we have a few

The Saipem 7000
Lifting facilities main crane:
2 twin S 7000 model fully revolving bow mounted Amhoist
cranes. Main blocks tandem lift: 14,000 t
very very little in lifting capacity, in real world terms i would have thought
however the saipem does have a big advantage in the fact it has the option of an additional J-Lay tower which can be fitted which the Thialf doesnt
