In April 2007, IHC Merwede Offshore & Marine was granted the order to design and build the new Multi Purpose Offshore Support Vessel for Hornbeck Offshore Services.
The vessel’s keel was laid on 23 July 2008 and will bear the name Hos Iron Horse. The naming of the vessel will take place upon delivery in the third quarter of 2009.
Hornbeck Offshore Services intends to use the vessel in first instance in the shallow waters of the Mexican Gulf. With her deepwater cranes, deck cranes and moonpool the vessel can be used in a wide range of offshore construction activities. The vessel can also easily be adapted to a charterer’s specific wishes and requirements. The moonpool facilitates subsea operations which can be supported by two work class ROVs which are housed in a hangar.
The vessel is equipped with a 400-metric tonne heave compensated mast crane capable of working at a 9842.5 ft of water depth and a 120-metric tonnes heave compensated offshore knuckle boom crane. Furthermore the vessel has a helicopter platform and accommodation for a crew of one hundred.
