Thermal Insulation & Integral Strakes
On the majority of deepwater developments, for fields greater than 1000msw, thermal insulation is often required on all exposed pipeline structures including Subsea Manifold, Xmas trees and Spool Piece pipelines. As the outer diameter of the pipeline increases due to the additional insulation requirements, this also increases the risk of VIV.
We manufacture thermal insulation shells incorporating a strake profile moulded into insulation shells and the solution has been successfully used on many projects.
With the increasing number of deepwater field discoveries, it is anticipated that the requirement for integral VIV strakes will increase accordingly.
By adopting the integral strake principle with a thermal insulation requirement, we can design a dual function engineered product to the client's exact thermal and VIV suppression requirements.
Other variants are available and our experienced design department can develop project specific systems.
