Drydocks World, the international service provider to the shipping, maritime, offshore, oil, gas and energy sectors, announced the completion of a major refurbishment carried out on National Drilling Company’s (NDC) Offshore Drilling Rig Al Ghallan. The project is part of a series of four rig repair and refurbishment projects signed with NDC in 2013. Before that, eight projects were completed. The numbers of projects carried out for NDC have progressively increased over the years.
Drydocks World claims a well-established reputation in the rig repair, refit and refurbishment segment. The company has successfully dry-docked, repaired and refurbished 125 Offshore Platform Vessels (OPV) belonging to major companies. The shipyard has extensive experience on drilling rigs and jack-up drilling units. There are instances where a basic hull structure was transformed into a complete OPV with newly fabricated bracing legs, columns, spud cans, accommodation structures and jack up and drilling systems.
His Excellency Khamis Juma Buamim, Chairman of Drydocks World & Maritime World is a staunch advocate of offering quality services to the offshore oil and gas and energy sectors as he foresees growing opportunity in these rapidly evolving sectors. According to him, “We are grateful to NDC for their continued faith in our services. We offer services that are suited to the company’s requirements related to rig refurbishment and refit. We have the capability to meet all the requirements of NDC and plan to develop the rig business further by joining hands with major suppliers and certified subcontractors.
