During top-hole drilling, the project team installed a system, provided by IKM Group, which removes drilling fluids (“mud”) at the well openings. The system prevents the discharge of drilling fluid, reducing environmental impact. It is designed for use with high-performance drilling fluids able to increase efficiency.
The main drilling campaign will be conducted from aboard the platform using a separate tender-assisted drilling unit. This removes the need for a heavier platform rig and lowers costs.
The project team have been able to reuse eight giant tendon support buoys first deployed on the Mars B project in the Gulf of Mexico. The buoys temporarily hold the ends of mooring tendons, or tethers, in place until they can be connected to the platform during installation. The reuse of support buoys demonstrates how Shell replicates its approach across regions, while using standardised equipment, to boost efficiency.
The Malikai platform uses a special kind of pipe, or riser, for both drilling and production, each with a single lining. A system onboard holds the multi-use risers in place overhead. The innovative approach eliminates the cost of using two traditional sets of risers while cutting the number of steps needed to drill a well.
In July 2015, the project team successfully jacked up the topsides and moved – or skidded – them onto the platform legs in the fabrication yard at Pasir Gudang. The “superlift” was the world’s highest jacking and skidding operation for a platform of its scale, reaching a height of 40 metres.
