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.
Edvard Grieg and Martin Linge jacket clusters and
buoyancy tanks
Client: Kvaerner Verdal AS
Period: Quarter 3 2012 to Quarter 3 2013
Kvaerner Verdal AS awarded the contracts to fabricate pile
sleeve clusters and flotation tanks for Lundin’s Edvard Grieg
jacket and Total’s Martin Linge jacket to Harland and Wolff
Heavy Industries Limited.
Harland and Wolff’s scope of work comprised the fabrication
and delivery of four pile sleeve clusters for each jacket. The
clusters each weigh approximately between 400 and 500
tonnes and are vital elements of the overall jackets. Harland
and Wolff also supplied flotation tanks for both jackets.
