AMPP Paper 16210-2021: Long-Term Performance of a Subsea Wet Insulation Material

�� FREE PREVIEW (First 5 Pages) ✔ First 5 pages free to download · No email required · Full document available after purchase This paper details the long-term performance assessment of a polyphenylene sulfide (PPS)-based material designed for subsea wet insulation at 180 °C. It addresses the growing need for materials capable of withstanding higher operating temperatures in deeper water oil and gas exploration. The study involved 12-month tests in seawater according to ISO 12736, and 12-month nitrogen exposure tests. The paper presents the results and evaluation of this material’s performance under harsh conditions, focusing on its suitability for HPHT subsea applications. It explores the material’s thermal conductivity, tensile strength, and ductility, and discusses its potential as a cost-effective solution for operating temperatures of at least 180 °C when used in combination with polypropylene-based systems. The experimental procedure, specimen analyses, and results are thoroughly detailed, providing valuable insights for material selection and performance prediction in subsea environments. The first five pages are available for free preview.
