Singapore's Keppel Fels has been awarded three new contracts from repeat customers worth a combined US$300 million.
The first contract will see the yard build a KFELS B class jack-up for fellow Singaporean-based company Star Drilling.
The rig will be used for operations in water depths of up to 350 feet, off the coast of India, and be capable of drilling to a total depth of 30,000 feet.
Keppel said the rig was scheduled for delivery in the fourth quarter of 2014.
The remaining two contracts will see Keppel carry out upgrades on semi-submersible drilling rigs for Ensco and Diamond offshore.
Under the scope of the Ensco contract, Keppel will carry out upgrades on the semi-submersible Ensco 5006, including the upgrading of the living quarters and other contract-specific upgrades for for the rigs upcoming contract on the Inpex-operated Ichthys project off Australia.
The rig is expected to arrive at the Keppel Fels yard during the first quarter of 2014, with redelivery the following quarter.
For the contract with Diamond Offshore, Keppel will carry out the fabrication and installation of four 24-foot diameter stability columns and new lower hull inboard pontoon sponsons on the semi-submersible Ocean Patriot, as well as carry out upgrades on the rigs living quarters.
Work on the Ocean Patriot is expected to start in June this year, with redelivery scheduled for the end of the year.
Following the completion of the upgrades the rig will be chartered to Shell for work on the Fram field in the UK sector of the North Sea.
