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.
