The Heidelberg Spar will be the 17th delivered by Technip (out of 20 worldwide) and thus demonstrates the Group’s leadership for this kind of floating platform and ability to tackle ultra-deepwater developments. In a water depth range of 590 – 2, 382 meters, Technip uses both dry and wet tree completions. Technip built 14 of these Spar hulls (two of which are currently being built) for deployment in the Gulf of Mexico, at its Pori yard in Finland. The Kikeh platform (including topsides) was built at MMHE’s yard in Malaysia for deployment offshore Sabah. Low motions make the Spar ideal for supporting Steel Catenary Risers (SCRs). The Spar can support full drilling facilities or accommodate Tender Assisted Drilling (TAD). The Spar technology continues to evolve with new innovations for:
- Ultra harsh environments in the Northern North Sea
- Ice resisting structures and moorings for the Arctic region
- Condensate storage for remote gas field developments
- Open sea floatover installation of large topsides
Technip has designed the topsides for three Petrobras deepwater production semis for deployment offshore Brazil. Technip was also responsible for the engineering and supervision of the topside installations by floatover. The 3 projects, P51, P52 & P56 represent the largest topsides floatovers onto semi hulls in the world. Semi platforms are suitable for mid and deepwater production and drilling operations with a large topside capability up to ca 40, 000 tonnes. Good motions permit the use of SCRs in deepwater (but not dry trees). Technip is developing its own semi-submersible hull design – to be available globally through its Integrated Platform for Analysis & Design software module. This semi-sub hull design is being developed for both wet and dry tree applications.
Tensioned Leg Platforms (TLPs)
In water depths up to 1, 500 meters, the Tensioned Leg Platform (TLP) offers a cost-effective platform for supporting dry trees. Technip has worked with experienced TLP designers to develop its own conventional TLP design. Market-ready designs are available for South East Asia that can utilize Tender Assisted Drilling (TAD). These designs, and others incorporating full drilling, can be readily adapted to other regions.See also:
