“What our oil and gas sector urgently requires now is a genuine co-operation between government, industry and the offshore trade unions to respond to this on-going crisis, alleviating the pressure on the industry while protecting employment rights.
“This is the only way we can begin to build a safe and sustained recovery for the UK offshore sector.”
OCA chief executive Bill Murray said the vote in favour would allow both companies and staff members to move forward amid challenging times.
