Self Elevating DP equipped Support Vessel

ELEVATING SUPPORT VESSEL This vessel represents a new class of offshore service vessels. It is purpose-built to serve a niche in the well service and construction market where other vessels are less suited. It is designed as a jack-up Heavy Intervention Vessel with sufficient capacity to undertake all classes of well intervention by use of its Le Tourneau Derrick that can be deployed on cantilevers or lifted directly on to a wellhead platform by means of the vessels own 300 ton heavy lift crane. Power generating capacity and large deck-space make the vessel an ideal Tender Support Vessel. Because of the heavy lift crane, additional crane barges are not required for lifting on or off modules and equipment from platforms during modifications or decomissioning.

The vessel is self-propelled and equipped with dynamic positioning (DP 1) and can operate independent of additional tug boats for positioning and in-field moves between assignments.
