Jackup Rigs Refurbished
In 1976, the oil drilling rig “Al Ghallan”, a three-leg, rack-and- pinion jacking unit, was the first mobile offshore drilling unit (MODU) commissioned by National Drilling Company (NDC), the leading drilling company in Abu Dhabi, United Arab Emirates. Built in Clydebank, UK by Marathon Shipbuilding Co. Ltd., Before refurbished, Al Ghallan used to have an aft hull slot for oil-well-platform approach. A total of nine units owned by NDC have been classed and handled by GL Abu Dhabi Maritime Services since 2000.
Hand-in-hand. When the prices of new offshore drilling units skyrocketed in recent years, NDC launched an initiative to upgrade their existing fleet, called Rig Integrity Assurance Program (RIAP). The refurbishing project consists of two ma- jor phases: basic design approval, and shipyard supervision and initial surveys. While the basic design has been handled and approved by the GL Industrial Services Oil & Gas division in Hamburg, GL Abu Dhabi has been in charge of supervising the construction, conducting the surveys and coordinating the detailed design of the units to be rebuilt during 2008 and 2009. The works are carried out at the Lamprell and MIS Ship- yards in Sharjah, 170 km from Abu Dhabi. The modernized Al Ghallan was recently redeployed in the Gulf.
