Elgin Brown & Hamer (EBH) Namibia announced the successful conclusion of a major repair project agreement with Sapura Energy.
EBHN acting CEO Heritha Nankole Muyoba said the entire project was completed without any incidents.
“Considering the number of people, the hours worked and the challenges we faced, this was a truly notable achievement. We anticipate that this rig project is the first of a number that will provide Namdock as well as our relevant stakeholders and the Walvis Bay community with strong sustainable revenue into the future.”
Muyoba added that the project further illustrates that Namdock has the ability to subcontract out specialist functions and see these through to completion.
The SKD Jaya project for example required the offloading of a very large item of drilling equipment. This posed a challenge since the quayside was never designed to handle such a heavy piece of equipment. To avoid damage the item was offloaded directly onto two unsynchronised flatbed units and transported to a destination where it could be repaired.
BBLT project manager Olivier Le Touzo explained that the ‘sail-away’ date for the completed project was 11 May 2019 and said a final inspection found that everything was done to satisfaction.
The SKD Jaya project is the latest in a series of high-level repair projects, which includes the replacement of the bulbous bow of the ship Huascar and the repair of the Angolan floating dock among other projects.
The project involved the reactivation of the SKD Jaya rig, a semi-submersible tender assisted drilling unit.
The vessel had been cold-stacked offshore of Trinidad for the past few years.
A four-man EBHN team flew to Trinidad to carry out a thorough assessment of the scope of work needed on the SKD Jaya. The rig was then transported to Walvis Bay on the heavy-lift vessel Hua Hai Long.
The complexity of reactivating a rig of such magnitude is considerable. The structure is 94 m in length, 36 m wide and more than 20 m high.
The Namdock team were charged not only with restoring this vessel to a seaworthy condition. They also had to ensure that it was safe and fully compliant with maritime legislation. To do this required highly complex work and involved a range of disciplines including rigging, fabrication, electrical and mechanical work, carpentry and painting.
To complete the scope of work, the EBHN team examined every square metre of the SKD Jaya and carried out maintenance, replacement or repairs as required. This involved 17 different ‘sub-projects’ which included ensuring that the accommodation and catering facilities were all in good order.
Other sections of the project entailed the refurbishing and testing of drilling equipment. The operability of all lighting, signal and fire safety equipment had to be checked.
The anchors and anchor wires were removed and rehabilitated. The deck crane cables were removed and load tested.
The engines, generators and heat exchangers were serviced and repaired. The fog and weather monitoring systems were calibrated and all anodes were replaced.
The re-certification of the life boats, servicing and load testing of all davits, and the replacement and drop-testing of the helideck perimeter netting were also done.
Further tasks included the removal and lab testing of the blow-out preventer test pump, overhaul of all valves on the rig, assisting RigNet technicians with all satellite antenna connections and supplying and reinstalling radio survey and satellite compass equipment.
Sapura Energy also had many requests for tools, consumables and local repair services, to which EBHN responded quickly and efficiently.
