Ice conditions, low air temperatures, and remoteness are affecting the functionality and operations of offshore wind vessels. In addition, cold climates and ice have an impact on the economics of offshore wind installation and maintenance. Vessels without proper ice class have limited capabilities to perform their duties in icy conditions, which may, at worst-case scenarios, interrupt the construction or operation of wind farms. Nordic countries, compromising of Finland, Sweden, and Estonia, are in a planning phase to build more than 5,000 offshore windmills, that require year round operation that includes the lengthy ice season.
Vessels with proper ice class and design can perform their duties year-round, including in icy conditions, allowing wind farm construction season can be extended during the winter months.
ABB has comprehensive bridge-to-propeller solutions for various vessels operating in wind farms, from construction to operation and maintenance. Modern integrated power, control and propulsion technology will enable safety, efficiency, and flexibility for the newly built ice class offshore wind vessels.
This paper will discuss modern propulsion technology available for various vessels operating in offshore wind farms through case projects. Specific focus will be on vessels operating in ice conditions to meet the performance and ice operation needs.
