Ultra-deep offshore project benefits from subsea insulation
The Kaombo project, operated by TOTAL, is located off the Angolan coast. Water depths reach up to 1,950 metres, which leads to extreme temperature and pressure conditions. This means the technology used has to be both reliable and cost-effective. ContraTherm® C25 had the credentials required.
Highlights
Cost saving insulation sleeves
The flexibility of the ContraTherm® C25 system enabled our team to simplify the design of the insulation sleeves from the original design. This reduced moulding complexity, reduced wastage, simplified tooling design, increased production speed and reduced cost. We achieved this without compromising the working performance, material structural quality or 25-year design life of the shells.
A two stage installation process
Our team undertook a two stage installation process to enable a greater degree of flexibility. Firstly, the insulation was applied to the bulk pipes at AIS' UK facility before it was applied to the field joint sections at AIS' subcontractor facility in Angola. The insulated components were then handed over to the customer for installation. We worked closely with the customer throughout to ensure the work was successfully completed within the timescale required.
