Self-installing platforms are a viable option for shallow-water development, according to Brian Roberts, vice president of business development at Technip. Roberts told participants at PennWell's eighth annual Offshore West Africa conference in Abuja, Nigeria, that a self-installing design called the jackdeck is ready to be deployed.
Citing the TPG 500 series of production jackup platforms as the predecessors of the design Roberts said the jackdeck is "born of proven technology."
The jackdeck consists of a conventional integrated truss deck on legs. An anchored barge installs the jackdeck by allowing it to jack into position from the deck in one operation. The process reduces risk and cost, Roberts said, because no heavy-lift vessel is involved.
Another plus for the technology is that it makes abandonment simple when the field reaches the end of its productive life, he said. The jackdeck is removed through a reverse installation procedure.
The jackdeck is ideal for offshore West Africa, according to Roberts; however, the design is not limited to benign environments. Technip has designed a heavier and more robust harsh-environment jackdeck suitable for Atlantic Canada, he said.
The jackdeck has the potential to bring fields on production quickly, which allows a very favorable return on investment, Roberts said. The new equipment, "gets production going as soon as possible."
