Blackford Dolphin mobile offshore drilling unit renewal survey

Client: Dolphin Drilling Ltd Period: Quarter 4 2013 to Quarter 2 2014

During the pre-arrival phase Harland and Wolff invested in site facilities in preparation for the rig arrival, creating an additional large pipe fabrication workshop and a mechanical outfitting shop. A purpose-built two-storey project office, large enough to accommodate 140 engineers and management and local to the dry-dock, was also erected. The main work scope for the rig was a special periodic survey (SPS) that was required prior to commencing its next contract in the North Sea area. The survey included replacing over 3,000 metres of pipe, of which 700 metres was in the ballast tanks, and fabricating/installing over 300 tonnes of structural steel throughout the rig. It also involved fabricating and installing a new deck in one of the columns to support a new rig air compressor and dryer, complete with the electrical, mechanical, piping and HVAC (heating, ventilation and air conditioning) installation and integration with the rig system. The project expended circa 1.4 million man-hours with upward of 1,000 personnel on site at the peak working 24/7 shift pattern, including over the Christmas holiday period.
