Danish shipowner Esvagt has expressed concern that it will face a labour shortage as the country expands its wind farm construction plans.

Parliament this week approved new schemes to add two "energy islands" totalling 5 GW at Bornholm and on an artificial island in the North Sea, as well as a new 1 GW offshore wind farm at Hesselo.

The agreement also paves the way for carbon dioxide taxes as part of moves to cut emissions by 3.4m tonnes by 2030.

The new deal "turbo-charges" the expansion of offshore wind in Denmark, which is good news for the 200 Danish ships operating in the sector, shipowners organisation Danish Shipping said.

The plans could create 85,000 full-time jobs over the next 25 years.

Already a struggle

But Peter Lytzen, a manager for Esvagt in Esbjerg, told the Berlingske daily the company has 1,000 staff and already faces challenges in finding new people.

"I read the report and think it is some hefty numbers. But just being a part of that reality is also enough for a company like Esvagt. That's the one part," he said.

But he added: "The second part is that we as an industry must remember that we have to have employees for this. Even today, we cannot get the Danish sailors that we need in Esvagt."

Continuing to provide routes to education and qualifications are vital if labour shortages are to be avoided, he said.

The company is looking to cut costs in the downturn. Directors and senior managers are taking a 15% cut for a year, while other managers are losing 10% of their pay.

Onshore staff have been consulted about a voluntary 5% cut.
