KNUD E. HANSEN A/S is often at the forefront when it comes to identifying new markets and designing new classes of vessels to meet the needs of operators. For example, we were among the first to see the need for dedicated vessels for the installation of offshore wind turbines, and in 2001 we designed the “Resolution”, one of the first of its kind. In recent years, we have taken the concept even further and developed the world’s largest vessel of this kind, delivered in the summer of 2012, the PACIFIC ORCA .
For access to offshore wind turbines in higher sea states from larger vessels KNUD E. HANSEN A/S has developed the ’Wind-Bridge’; a telescopic heave and roll compensated gangway. Unlike similar solutions the Wind-Bridge can hook on to a standard boat landing regardless of the direction of the waves, current and wind.
For smaller access craft used for servicing offshore wind turbines, KNUD E. HANSEN A/S has re-assessed the usual catamaran model and instead developed a solution that uses a trimaran hull based on its superior sea keeping and ride comfort.
For upending mono-piles from a supply vessel by a floating crane with fixed hoists KNUD E. HANSEN A/S has designed a heave compensated trolley, which runs on tracks on the supply vessel and supports one end of a mono-pile.
Stored on deck, the guide does not take up much space, but in its deployed position the X-Y-Z adjustable guide is able to reach down to 5.5m below the deck level. This solves the problem of how to support short mono-piles from the elevated deck of jack-up vessels without using pile extensions.
