Offshore Energy Branch 


National Union of Rail, Maritime and Transport Workers (RMT)

We are the Offshore Energy Branch of the National Union of Rail, Maritime and Transport Workers (RMT).  We were first formed as the Offshore Industry Liaison Committee (OILC) in 1989, then in 2008 we merged with the RMT.  The RMT itself was formed on 10 September 1990 through a merger of the ‘The National Union of Railwaymen’ and ‘The National Union of Seamen’.  

We organise workers in:


  • Production, engineering, maintenance, and fabric maintenance
  • All catering grades, administration and logistics
  • Drilling, well services, inspection, survey and testing
  • ROV operations, diving (inshore and offshore), dive support, pipe lay, cable lay and lifting
  • Marine crew on flotels, crew transfer, walk to work, supply, stand by, and anchor handling vessels
