Hundreds of workers who are part of North Sea diving crews have rejected a revised pay deal made on behalf of six employers.
The Offshore Diving Industry Agreement (ODIA) is a pay and conditions settlement on behalf of Subsea 7, KD Marine, NSea, Helix Energy Solutions, Technip FMC and Rever Offshore (formerly Bibby).
Around 1,000 workers are covered by the agreement which is negotiated every three years.
A pay offer for the latest period was first rejected in November last year, and a further ballot was carried out by the RMT Union on March 4 following a revised offer.
Of an 82% turnout, 87% voted to reject the proposal.
RMT said further talks are scheduled with employers in the coming weeks.
If a resolution cannot be found, the next step is industrial action.
Dive crews took a pay cut when the last deal was made in 2015 amid the oil and gas downturn.
RMT regional officer Jake Molloy and Hamish Petersen, chairman of the committee of company signatories for the ODIA, issued a joint statement.
It said: “Following the recent ballot result, both parties have discussed meeting again in order to make further progress.”
ODIA dates back to the early 1980s and governs minimum rates of pay, allowances and health insurance for UK diving workers.
