InterMoor Inc. has extended its capabilities and service range by becoming the first US-based company to achieve certification under Det Norske Veritas (DNV) 413: Service Suppliers Engaged in Renewal Survey Examination of Mooring Chain Intended for Mobile Offshore Units.
This means that InterMoor Inc. can now inspect, certify and recertify mooring chains and related components such as connecting links and wire rope for mobile offshore units that have or will have DNV classification (DNV-OSS-101 and 102). There is also scope to include water blasting of chain, visual inspections, measurements and mechanical and non-destructive testing.
