Aquaterra Energy, a leading global offshore engineering solutions provider, announces it has completed the delivery of a Sea Swift conductor supported platform (CSP) for DeNovo Energy in the Gulf of Paria, offshore Trinidad and Tobago. This is the first platform of its kind to be installed in the country, and was completed in just ten months.

Located in the Iguana field, the Sea Swift was installed from a jack-up rig in 27 metres water depth, accommodating up to four wells and includes local power generation, manifolds and a control system. To meet the tight delivery timetable, the design phase of the project overlapped with the fabrication of the Sea Swift. It was built by Chet Morrison Contractors who also designed and installed the Iguana pipeline to shore.

Drilling of the first of a three-well development campaign has commenced, using the Well Services Rig 110.

Trinidad Sea Swift Platform – in place

Aquaterra’s Sea Swift platform has been installed across a number of shallow water locations, including three in West Africa, one in Egypt and one in the Far East. Its deepest deployment to date is at 65 metres water depth using two subsea structures, offshore Peninsular Malaysia. It is also the largest known CSP in terms of topside weight at more than 400 tonnes fully laden.

Stewart Maxwell, Technical Director, Aquaterra Energy

Stewart Maxwell, Technical Director of Aquaterra Energy said: “The Sea Swift platform is an ideal solution for shallow water field developments, such as Iguana. From concept to completion, this project showcases Aquaterra’s agility and ability to work quickly and efficiently to deadline and budget.”

“The promise of a more efficient and tighter delivery envelope is an attractive option for operators looking to accelerate the journey to first oil and natural gas in marginal field developments,” added Maxwell. “As the price of fabricated steel has fallen, it means the straight cost differential between a conventional jacket and a Sea Swift is also falling. The overall cost savings really come to the fore when using smaller and more agile fabrication yards, and a jack-up for installation ensures simpler project management and reduced risk.

This first for the upstream industry in Trinidad and Tobago opens up further opportunities for the country, which has several stranded reserves full of development potential.”
