use of earlier generation jack-up drilling rigs
Posted by colin hardy to Equipment, 2010-01-05 04:29:50
Given the huge cost involved in new build of offshore vessels, earlier generation jack-up oil drilling rigs, no longer used for that purpose offer a comparatively economic avenue for the offshore wind industry. Available in various configurations, and built for operations in waters ranging from 80' to 800', there basic stable base and physics offers the industry a proven resource for stable and safe offshore operations, whether it be for heavy lift operations for installation ( crane systems fitted ), maintenance, service, supply or accomodations. Also, given the size and load capabilities of some of these rigs they could be converted as well into offshore gathering and distributing power stations and permanent offshore bases.
Thanks, for more information.

The problem with life expired equipment is that the maintenance costs are prohibitive - this is already been an issue for re-use of rigs and pipelines for the Carbon Capture and Storage market (CCS),
We also noticed that most vessel owners would not want to just have offshore wind farm assembly vessels since this market is still risky. Instead they want multi-purpose vessels that can be u...

Discussion placed on LinkedIn: Do new build offshore vessels hardly give any added value in comparison to earlier generation jack-up drilling rigs?
Answer: Kurt Thomsen (Owner, AOS)
Yes, mainly because jack up drilling rigs are useless in this industry.

Of course you do not use a drilling jackup for the purpose, but some of the design aspects are applied in designing an installation vessel for offshore windmills. Speaking from the designer and builder of both jackups, installation vessel, drilling semi,etc. See our web at www.keppelfels.com

The main benefit of newer jack ups (installation) not sure why you would be using drilling jack ups on wind farm installation is the benefit of state of the art jacking technology which should allow them to operate in a wider range of geotechnical and tidal conditions. Older jacking systems cannot maintai...

The arguement is between using a MODU-Jack-up through adapting your work procedures and installation aids; and using a construction jack-up which will have the benefit of built to purpose configuration and equipment - which reduces the effort and expenditure of adapting a MODU-JU...

Agree with Philip. But when you start to decide on the class notation for this jackup with DP2, some class authority has different interpretation and requirements, say comparing DNV and ABS. DNV may probably tend to look at ship rule and ABS may tend to simplify it under MODU and cost is an issue here when we star...

Drilling jack-up platforms can have advantages above construction jack-up platforms. Especially when installing monopiles in very hard soils, where pile driving is not feasible and drilling is required. Since all drilling is shallow the derrick could be replaced by a large crane, also suitable for WTG installation.

The jackup concept tied to offshore wind energy has been developed and patented, the use of common jackup designs are preventive, due to overall cost, basiclly $/T, so a special non-convential design must be adopted. In addition there are several load conditions that a common jackup does not experience, due to the nature of the turbine and its special design loads. You can see this design at ou...
