The pics are of the Siem Moxie!
What is X BOW? X-BOW vessels are characterised by the absence of a bulbous bow. Their bow slopes backwards above the water line which results in reduced resistance and improved wave slamming characteristics on the foreship. Since 2006, forty vessels with the X-BOW design developed by the Norwegian vessel designer Ulstein Design AS have been delivered or are currently being built. One of them is the “Siem Moxie”.
Designed for specific tasks in wind farms in the North Sea as well as in the Atlantic, the work boat with a length of 74 meters and a beam of 17 meters will be the first X-BOW vessel equipped with Voith Schneider Propellers. The “Siem Moxie” will be fitted with two electronically controlled VSP of the size 28R5 ECS/234-2. They have a propulsion power of 1,850 kW each and will be arranged in the stern. The two Voith Schneider Propellers will also be used for active roll stabilization as well as for dynamic positioning (DP class 2). The entire propulsion system as well as the DP system are controlled centrally. The interfaces for propeller and roll stabilization control will be provided by Voith.
