API RP 17U PDF
This recommended practice (RP) provides guidance for the performance, qualification, application, quality control, handling, and storage requirements of wet and dry thermal insulation for subsea applications in the petroleum and gas industries. This guideline also covers the inspection of the insulation, and the repair of insulation defects.
Annex A specifies the minimum recommendations for the performance qualification testing and inspection testing requirements for wet insulation systems (insulations in direct contact with seawater).
Annex B specifies the minimum recommendations for the performance qualification testing and inspection testing requirements for dry insulation systems (insulations not in direct contact with seawater).
This document is not intended to address either installation procedures or proprietary fabrication of any particular insulation type.
This RP is not a prescriptive document. If agreed between Company and Supplier, prescriptive requirements for wet insulation systems presented in ISO 12736 could be utilized.
