The term ‘Walk-to-Work’ originates from the desire to offer offshore personnel the capability to transfer to offshore structures without requiring them first to climb up a ladder or be transferred using a transfer basket on a crane.
The Installation Support Vessel Siem Moxie was developed specifically to address this demand on offshore wind farms, where the pull-in teams on foundations and platforms were unable to access the structures in harsher weather conditions. The Installation Support Vessel Siem Moxie was the first of her kind to operate in offshore wind farms in Europe. She was designed and built to allow offshore personnel safe access to foundations and platforms in calm and rough seas. She has proven her worth in the field, making up to 54 successful connections and transfers in a 24 hour period. She has shown that she is able to work in up to 3.5m significant wave heights.
The X-Bow hull is designed to slice through the waves, just like a Viking longboat."
The active motion compensated gangway is situated in the centre of the vessel and the X-Bow hull is designed to slice through the waves, just like a Viking longboat. This integrated design of gangway and hull provides the ultimate stability in adverse sea and weather conditions. The Installation Support Vessel Siem Moxie provides accomodation for 60 persons, where by up to forty are available for project staff.
In addition to the Installation Support Vessel Siem Moxie, we have a number of other vessels with various characteristics which have experience operating fitted with Walk-to-Work gangway systems. These have been used in the field to provide Walk-to-Work access both on installation projects as well as inspection, maintenance and repair works. The Siem Marlin, the Siem N-Sea, the Siem Spearfish, the Siem Stingray and the Siem Garnet have all been successfully deployed in this fashion with more to come.
