Subsea insulation covers

Insulation covers prevent high-temperature oils from cooling and solidifying and ensure a continuous flow during the whole field production.

Insulation covers are made of a field proven rigid polyurethane system for application up to 80 °C
Each insulation cover is composed of half shells, each including a sealing system, closure arrangements, flooding system and an optional venting system
Sealing system is made to limit water movements and exchanges
Designed with thermal analysis to reach a target cool down time
The lifting points ensure our insulation covers are easy to manipulate on board
Insulation covers are designed in compliance with international offshore standards, including API 17-L1, API 17-L2, DNV–RP- B401.

Removable subsea insulation covers

Subsea equipment may require thermal insulation to maintain operating temperatures and protect against heat loss, but permanent insulation can make access for inspection and maintenance more difficult. Removable covers provide thermal protection while allowing equipment to be accessed when required.

Benefits

Maintain flow assurance in demanding subsea environments

Designed around the specific thermal requirements of each project, AIS insulation covers provide reliable long-term performance without routine maintenance. Their robust construction, effective sealing and bespoke design help maintain insulation performance throughout the life of the installation.

Bespoke and cost effective

Every insulation cover is tailor made to order and takes into account specific project loading constraints and temperature requirements in order to maximise ease of use and minimise costs.

Compliant to standards

Our insulation covers use a field-proven rigid polyurethane system for applications up to 80 °C. They are designed to meet international offshore standards including API 17-L1, API 17-L2, and DNV-RP-B401.

Easy to install

Our insulation covers need only standard tools for installation and can be fitted by divers or ROVs. Durable materials mean low maintenance and a long life span. End of life has also been considered.
