Evaluation of subsea wet thermal insulation coating materials via exposure to seawater for a 12-month period at high temperatures and high pressures is presented in ISO(1) 12736:2014. This is a harsh exposure regimen which few materials have been evaluated against for such a long time period and the ISO(1) standard deliberately does not present acceptance criteria for the test results.

How to interpret and apply the results of this testing to the design and qualification of subsea wet insulation systems is presented, in addition to experiences and challenges faced whilst undertaking this evaluation program with various materials at temperatures up to 150 °C and pressures up to 30 MPa.

Key words: ISO 12736:2014, failure mode analysis, risk analysis, material exposure testing, subsea wet insulation, polypropylene, material qualification
