Harland & Wolff completed the dry docking and SPS Class Renewal Survey of the Byford Dolphin Mobile Offshore Drilling Unit (MODU) during the summer.
The rig left Belfast following a six-month dry docking in the ship yard’s main Building Dock.
Harland and Wolff Director of Marine and Offshore Unit Repair, James Lappin, said “Over the years Harland and Wolff and Dolphin Drilling have collaborated on several occasions, having fabricated pontoons, column extensions, power generation and accommodation modules for other vessels in the Dolphin fleet.”
