Aquaterra Energy successfully installs Sea Swift structure in Angola
Aquaterra Energy has recently successfully completed the first phase of the installation of the Sea Swift structure for a major West African operator.
This is the first application of Aquaterra Energy's Sea Swift platform and the installation has gone extremely smoothly. The structure was designed, project managed and installed by Aquaterra Energy personnel. The platform was fabricated locally in the UK; a second, almost identical structure has recently been fabricated in the UK and will be installed Offshore Angola during 2008.
The Sea Swift conductor-supported platform concept offers a field proven technology for reducing costs in shallow water field developments. Versatile in its application, Sea Swift combines the advantages of a platform with the rig-run benefit of a subsea development, in a package with lower capital and installation/intervention costs than either.
The structure, located in a water depth of 27 metres, was installed using conventional drilling and lifting techniques from a drilling rig. The minimum facilities platform comprises a subsea "mini jacket" weighing 45 tonnes and a topsides with a gross weight of approximately 110 tonnes (including all equipment). The structure is supported by 3 No. 30" conductors which are drilled through, and then grouted within, the "mini jacket" structure.
The subsea structure and topsides structure were installed earlier this month; work is currently progressing well with the installation and commissioning of the topsides equipment.
David Rowson, Lead Structural Engineer with Aquaterra Energy stated, "We are delighted that the first phase of the platform installation has been successfully and safely completed - this is due in no small part to the professionalism and enthusiasm of our project team. We now hope to expand on this success and develop further Sea Swift opportunities in the future".
