EDrill-3 drilling equipment set (DES) is progressing ahead of schedule with all pre-commissioning activities completed in April 2015 at Megaway Engineering’s fabrication yard in Singapore. Preliminary commissioning and function testing of the Drawworks, Topdrive, Accumulator, BOP’s and offline activities cantilever (OAC) pipe handling equipment has been successfully completed in co-operation with equipment vendor specialists.
The DES has also been fully assembled with the mast scoped up in both quad and triple modes and the shaker tank mounted on both the ODS and DS sides. Next step will be to transport the DES to COSCO shipyard for full commissioning and integrated acceptance testing with the semi-tender’s power and control systems. When completed in August 2015, EDrill-3 will be the largest, most advanced semi-tender in the world capable of operating in severe environment and fully equipped to couple with any existing trussed spar or tension leg platform (TLP).
EDrill-3’s 186 foot Bootstrap Mast is shown here assembled in triple mode which is the optimum configuration to operate on tension leg platforms (TLP’s) exerting lateral acceleration forces up to 0.2G’s. The mast’s 1,000,000 lbs Hookload and 1,200,000 lbs Setback loading capacities give it the ability to drill 30,000' wells while simultaneously racking back production casing and tubing strings.
EDrill-3 Mast and Drillfloor are being readied for rigging down from Megaway's Yard in Singapore and will be loaded out on a heavy lift transporter to join the EDrill-3 semi-tender at COSCO yard in Guangzhou.
The construction of Energy Drilling’s latest semi-tender rig has marked a significant milestone with the successful installation of EDrill-3’s Upper Hull deck box modules in the first week of December, a little more than a month after the lower hull was launched in end October. The EDrill-3’s Upper Hull has been constructed and outfitted with major equipment packages in parallel with the Lower Hull since the project’s outset. Living Quarters module is undergoing pre-lift preparations and will be installed in the second week of December.
“The EDrill-3 is being constructed at Cosco Guangdong Shipyard in southern China. The project team is led by EDrill’s project manager, Jason Tan, and his counterpart, Zhu Qing from Cosco. A beaming Zhu Qing said, “We are very pleased with results of the upper hull lifting operations and fit up. A lot of engineering and planning has gone into this to ensure we have a smooth and safe operation. The project will now go into its final phase of completion, testing and commissioning. We want to make sure that our client has a first class rig ready by 3Q 2015”.
EDrill-3 is a four column Ocean Class design by MSC Gusto. It will be the largest semi-tender in the world when completed next year.
COSCO Shipyard uses a 2600MT floating crane to install completed Upper Hull module 60BG onto the Lower Hull columns and temporary support towers. Deck Box Module 60BG is the largest lift of the entire project and weighs in at 2500MT.
