Turbine installation and the levelised cost of energy: Bigger vessel payloads

By Hans Peter Johannsen, Vice President, Projects.

This is the third article in our series about reducing the LCoE in the offshore wind industry through optimising turbine loading, transport and installation.

A2SEA’s internal data supports wider industry observations that the cost of turbine installation per installed MW is, in fact, coming down. From our perspective (and remembering that turbine installation is a minor part of an wind farm’s overall development), there are gains to be made whenever we can load more megawatts at a time onto our vessels. This ability is strongly assisted by the increasing amount of power generated by larger turbines such as the MHI Vestas 8 MW. But that’s far from the full story.

Turbine Installation and the Levelised Cost of Energy: Taller and heavier

By Hans Peter Johannsen, Vice President, Projects.

This is the second article in our series about reducing the LCoE in the offshore wind industry through optimising turbine loading, transport and installation.

These days, A2SEA is as busy as ever, working through a pipeline of turbine installation projects that shows no sign of slowing down. Such healthy demand is a blessing, of course, but we’re equally lucky in that the purpose-built vessels SEA CHALLENGER and SEA INSTALLER were initially designed to handle not just the installation of turbines, but foundations as well. Why is that so lucky? It’s all about how much they can handle.

Turbine Installation and Cost Reduction: Handling Risk

Turbine installation and cost reduction - handling risk

By Hans Peter Johannsen, Vice President, Projects. 

This is the first post in a series about reducing the LCoE in the offshore wind industry through optimising turbine loading, transport and installation.

In offshore wind, few things dominate industry conversations as much as reducing the levelised cost of energy (LCoE). And certainly, with many years spent working to optimise equipment, procedures and safety, turbine installation contractors such as A2SEA have been able to become highly efficient, bringing the costs of installation down within the installer’s scope of control. In a series of articles, we’ll be discussing the steps we’re taking to achieve even greater efficiencies.  Continue reading →
