The Inverness-based business is on course to achieve another strong year of growth after doubling core profits to £35m in the year to March. Sales increased by 43% annually, to £358m, from £250m in the preceding year.
Iain MacGregor, chief executive of the family-owned group, said the company has benefited from buoyant activity levels in the waters off Scotland.
"The North Sea has been very strong and continues to be very strong," he said.
Mr MacGregor said Global Energy Group has capitalised on the efforts of oil and gas firms to boost North Sea production to meet strong demand for energy.
This has created lots of work for the group's projects division, which helps firms upgrade or extend existing facilities.
While Wood Group highlighted an apparent slowdown in spending on big new developments around the world by oil and gas majors, Mr MacGregor said Global Energy has seen no sign of spending slowing on the brownfield work it specialises in.
The company's decision to acquire the giant rig fabrication yard at Nigg in 2011 appears to be paying off.
"It's been really busy, we've had huge demand," said Mr MacGregor, whose father Roy founded the business.
Global Energy Group recently worked on the upgrade of a Floating Production Storage and Offloading vessel at the yard.
It hopes to start work next year on a £37m scheme to extend a quay at the Nigg Energy Park facility.
This will allow the company to handle more oil and gas business and help it win work from the renewable energy industry.
The maintenance arm has also achieved strong growth in the North Sea, helped by the acquisition of the A&B Welding business last year.
Overseas sales surged to around £60m from £20m. The company noted the increase in sales reflected the acquisition of the Vertech business in Australia and organic growth in the Gulf of Mexico.
Mr MacGregor said the company was on the hunt for more acquisitions overseas.
He said: "We have learned many lessons from growing a UK portfolio and have adapted our approach to developing international locations. This is yielding good results in Asia Pacific and also the USA."
The company's performance was praised by Misui, the Japanese industrial giant that acquired a 25% stake in the business in 2012.
Noboru Katsu, Operating Officer and Regional Client Officer for Europe, said: "The results announced today are highly impressive. We are confident this success will continue in the coming year."
The group recorded total sales of £340m in the first eight months of this year.
Earnings before interest, tax, amortisation and depreciation increased to £34.5m in the year to March, from £16.9m in the previous period.
Pre-tax profits increased to £29m in the year to March, from £13.5m.
