Members of Oil & Gas UK - the body representing the offshore oil and gas industry - held a "period of silent reflection" today to remember the four victims of a helicopter incident in the North Sea last week.
The group's chief executive Malcolm Webb said the grounding of the Super Puma helicopter fleet would cause "considerable inconvenience to the workforce and their families".
He said it could result in delays and flight backlogs as well as "potential adverse effects on offshore activities".
