Island Offshore Subsea’s Island Constructor president. IMR, however, hasn’t always been called IMR, and even today, IMR assets are only now being grouped, hired or partnered with, as supplier consolidation coincides with the ap- pearance of rules that allow longer ? eld life via asset “recerti? - cation”, a business stream shared by IMR vessel operators and
Then there are the operators: in Norway, a local news report at press time noted that Equinor has, in just three years, secured more than 130 years of “extended ? eld life” via rules-based recerti? cation and life extension measures.
A decade ago, Island Offshore and Oceaneering collaborated to give Equinor inspection services that got everyone through the credit crunch post-2008. ROVs led the inspection work, mostly of rig moorings, and Island Offshore’s new light well vessels awaited the new type of business they were built for.
Today, TechnipFMC owns a 51% stake in new Island Off- shore subsidiary, Island Offshore Subsea, the entity now in control of its light well intervention ? eet. As with Subsea 7,
TechnipFMC can now offer a construction vessel and riserless light well intervention (RLWI) and regular IMR to go with its subsea umbilicals, risers and ? owlines (SURF), EPCI and sub- sea production systems. “Our current track record delivering
RLWI services together with Island Offshore has signi? cantly increased production from more than 500 subsea wells,” said
