The conductor supported platform (CSP), installed in water depths of 23 metres, includes a 385-tonne topsides featuring a helideck, emergency accommodation and with provision for six wells.

Aquaterra’s workscope for the Amal-C platform involved the design of process, piping, electrical, instrumentation, control system and technical safety systems, as well as the design of new subsea production pipelines to the Amal-A platform.

The project, which took 18 months from design to installation, involved building a bridge link to the neighbouring Amal-B platform and reconfiguring the topsides pipework to create an improved production profile, the company says.

“The Sea Swift platform is an ideal solution for shallow-water field developments as it can be delivered from concept to completion quickly,” says George Morrison, managing director of Aquaterra Energy.

The Sea Swift modular system unites the advantages of a platform with the rig-run benefits of a subsea development, the company says. Several units are currently in operation in Asia Pacific and West Africa.

Aquaterra says the technology reduces platform costs, lowers installation and intervention costs and simplifies project management.

CSPs also allow early production by enabling wells to be drilled and completed with dry trees before the arrival of a main processing platform.

“The deployment of CSPs is increasing due to growing demand for modularised wellhead platforms which can be built and installed in smaller, discreet packages across a number of fabrication yards,” Morrison says.
