According to the poll of 276 offshore personnel from over 35 contractor members of the International Marine Contractor’s Association (IMCA), the results showed that the majority of employees understood how these schemes worked and were in favour of them.

It also revealed that around three-quarters of the respondents felt they should be in a competence scheme. However, only around a third of respondents had been asked for evidence of competence when moving between employers.

IMCA Chief Executive Hugh Williams commented: "We were highly encouraged, not only by answers to the questionnaire, but that so many people took part in it.

"It was possible for respondents to select more than one division from marine, diving, ROV and survey, and also to select more than one answer for what form of employee they were. This means that some of the results can suggest that more than 276 respondents took part; and also made comments."
