The workers aged between 23 and 28 are two and a half times more than the workers aged between 60 and 65, which indicates that the offshore industry is attracting new entrants.

Findings from the Oil & Gas UK’s 2012 Demographics Report state that the average age of the workforce remained the same at over 41 years.

The report also reveals that the offshore female workforce is just 3.7% of the total, with 30% of those working in catering.

A total of 52,300 people traveled offshore in 2011, which is 5% rise compared to 2006; Proportion of core offshore workers (those working over 100 nights a year offshore) has increased to 23,758, which comprises 45% of total workforce.

Oil & Gas UK employment and skills issues manager Dr Alix Thom said the oil and gas sector is a major driver for economic growth in the UK.

"There are many positives such as the increase we’re seeing in the number of workers travelling offshore and the big increase in the number of younger workers," Thom added.

"These lead us to expect that in the next few years, more people will join the UK oil and gas industry and gain experience than those who leave through retirement or relocation."

"Oil & Gas UK is working closely with its members and with OPITO to develop a collaborative strategy to address the skills demand and grow the talent pool further.
