WTIV
Wind turbine installation vessels (WTIVs) have specific needs, different from traditional oil and gas-focused offshore operations.

As is the nature of wind turbine installation vessels, they go through frequent repositioning. This proves to be challenging for the jacking systems if not properly taken into account. In addition, you need to be able to make a balanced judgement when selecting an operational profile – taking into account operations in more extreme weather conditions. Do you place higher design requirements on your WTIV or choose a reduced operation profile with more frequent sheltering?
