The company's energy operation in Glasgow currently employs 25 people and recently relocated from Maryhill to a city centre location.
There are a further 25 staff working in the maritime arm, which is thought to be the world's largest ship and offshore classification society.
DNV GL expects staff numbers in the Glasgow energy branch to hit 50 in the coming months as it gears up to try to take advantage of the predicted growth in the Scottish renewable energy sector.
DNV GL's energy section provides advice on all stages of renewables projects from feasibility and design through to operation and asset management.
Andrew Temple, head of global business developing in renewables advisory, said: "The industry in Scotland, from what we see, is quite exciting.
"From a growth point of capacity, Scotland has around six gigawatts of renewable energy with 13GW in the pipeline. To us that is a fantastic opportunity to grow our business.
"Our intention is to grow the Glasgow business area of energy to 50 within the first 12 months."
Mr Temple said staff based in Scotland will mostly focus on local projects but will be able to export their expertise to other parts of the business around the world as well as call on help from other DNV GL global sites.
He indicated DNV GL sees Glasgow as an engineering hub and one with a growing international reputation in the renewable sector.
Graduates are likely to form part of the intake the company is planning and Mr Temple suggested further jobs may be created in the future.
He said: "Everything is measured and what we need to do and ensure is we grow in a controlled manner that supports the industry here in Scotland.
"If we need to expand or grow further than those numbers then we will do so.
"We have space to do that and potential to look at other premises as well. We are not letting anything stand in our way to grow."
Recent research from Scottish Renewables suggested there were now a record number of Scots working in the industry with staff numbers estimated to be more than 11,000.
The organisation is hosting a renewables industry reception along with Glasgow City Council tonight.
Joss Blamire, senior policy manager for Scottish Renewables, said: "With more than 2000 renewables roles already, Glasgow is showing it can attract talented professionals to work in this growing industry.
"We welcome DNV GL as one of the latest additions to the city's renewables scene, and as a significant contributor to the local economy."
