There has been a shake up at the top of a growing Gorleston offshore company with the departure of managing director Steve Johnson.

CLS Offshore, which provides a wide range of services to the oil, gas and renewable energy industries, will now be led by Scott McMillan who joined the company at the start of the year.

CLS has seen rapid growth over the last few years, and it recently revealed a 28pc growth in its turnover.

Just two months after unveiling new headquarters at Maltings Lane it launched an engineering department.

Mr McMillan has a 25-year background in the oil and gas manufacturing and services sector.

Before joining CLS, Mr Mcmillan was Eastern Hemisphere general manager for US company Shaw Pipeline Services and was also general manager for Shaw Inspection.

CLS finance director Sid Anverali said the firm was delighted to have appointed Mr McMillan after his success at Shaw has seen him deliver year-on-year growth, with sustainable revenue streams of more than �50m a year.

'He is a driven individual who brings his leadership, management and operating knowledge to CLS. It promises to be an exciting and developing future,' said Mr Anverali.

Mr McMillan, who started his apprenticeship in Great Yarmouth with Turmeric Ltd, said: 'I recognise the potential and growth opportunities for CLS and look forward with enthusiasm to the challenges ahead.'

He has held several senior positions in the energy industry joining Shaw eight years ago. He moved to CLS as a senior project manager early this year and was promoted to managing director last week.

In a statement CLS said that Mr Johnson's had left the company to pursue other interests.

This year the company centralised it operation to one facility at Maltings House and carried out a �400,000 upgrade of facilities on the four-acre site.
