It is indispensable for an offshore drilling company to upgrade and/or renew drilling machineries as well as hull and marine systems installed onboard drilling rigs in order to maintain its competitive edge in the industry.
While recognizing the importance of enhancing the operational capabilities of existing rigs in accordance with their life cycles, the most effective approach in improving the quality of the rig fleet is to add a newly built rig outfitted with the latest available technology to the fleet.
To accomplish such requirements for strengthening JDC's rig fleet in the ever-advancing offshore drilling industry, JDC is keep carrying out not only engineering study for the life enhancement and upgrading of rigs but also Research & Development of new technology for drilling and marine.
- Project management for construction of the new jack-up rig, AL-KHOR
- Project management for construction of the new jack-up rig, HAKURYU-10
- Project management for construction of the new jack-up rig, HAKURYU-11
- Investigative studies and basic design for life enhancement of the semi-submersible rig, NAGA 1 (in 2003)
- Investigative studies and upgrading work for Deepdish conversion on the semi-submersible rig, HAKURYU-5 (in 2008)
- Investigative studies and basic design for upgrade of the existing semi-submersible rig to enable use at depth of 5,000ft (2007-2009)
- Upgrading work for Deepdish conversion and derrick replacement on the semi-submersible rig, NAGA 1
DEEPDISH CONVERSION is the work to attach a all-in-one structure called "DEEPDISH" (red part in the right 3D CG) to the hull bottom of a semi-submersible drilling unit. This will strengthen the stiffness of entire structure, thus increases the durability of the unit and fatigue life. This method enables us to reduce construction period and save costs compared with the conventional conversion method.
