■ Due to the complexity of maritime environments, offshore engineering equipment are facing long-term tests of factors such as:
High concentration of salt
High-intensity UV exposure
High diurnal amplitude
Impact and splash of ocean currents
Extreme weather (typhoon, rainstorm, hail)
■ for NB projects
High corrosion resistance
High film thickness in application
■ for M&R projects
Low surface treatment
Application on wet surface
Standard M-501 released in 1995 literally changed the way we choose coatings for offshore equipment. Since then, owners, engineers and product nominators have accepted standard M -501 and its principals.
Over the past 20 years, Norsok M-501 has earned its acclaim as a standard for selecting coating system for new building projects of offshore engineering based on performance.
Hilong offshore engineering coatings have obtained NORSOK M-501 certificate.
M-501 sorted coatings application in offshore platform into the following 9 types, among which class 7 requires the highest anti -corrosion performance.
