During the last quarter of 2003, Vuyk Engineering Rotterdam was contracted bySmit Engineering - part of the SMIT Group - to review a basic design for adynamically positioned anchor handling tug/supply vessel (AHTS), providing abasis for modular upgrading to diving support, oil recovery and other duties.In the first phase, SMIT intended to order two 70-ton bollard pull vessels and one120-ton bollard pull AHTS.After an international tender, resulting in offers from yards in The Netherlands,Norway, Spain and Singapore, Smit Transport & Heavy Lift B.V. ordered in March

2004 two 70-ton bp AHTS from the Keppel Singmarine yard in Singapore with anoption for two 120-ton bp AHTS. In July 2004 Smit exercised its option to build thisvessel.
