General DescriptionOwner: : SapuraKencana Australia
Year of Build : 2012
Structural Design : Rob Elks & Associates Fabrication : Phillip Engineering
Hydraulic Design : Pressure Dynamics
Control System Design : FugroTSM
Number Built : 2 Units
Operating Philosophy• The rig can be controlled subsea by diver
intervention
• The rig can be operated topside from a control cabin with minimal diver intervention. This can be extended to be fully automated from the topside with no diver intervention required
• The rig is self guide and self level as it tracks between rock bolt locations via feedback from the builtin gyro’s and sonars
• A reloadable cassette carries 8 rocks bolt assemblies of a typical saddle arrangement
• The drilling head can side shift for ease of aligning to the pipe
• Bottom restraining gates assist with initial punch through for hole penetration
• Drilling feed and RPM is recorded and monitored through the onboard computer
• 3 pan and tilt cameras, 3 zoom cameras and 8 lighting control allow full topside view of all operations
• The rig is operated via a Jupiter control box via hydraulics
• All fluids are environmentally soluble
• The hydraulic umbilical is 120m in length but can be extended to 240m
• Operating depth 5-20m, extendable to 100m with minor modifications
General Specifications• Operational mode: Air diving operation
(base case)
• Relocation mode: Self propelled as well as
pick and place by contruction vessel
• Pile / Rock Bolt Size: 219mm OD x 10.97 wt x 5.5m long
• Performance: Cycle time of <30min to drill/grout & traverse
• Reloading system: PISA magazine type system (8 RB assemblies)
• Drilling capacity: Double / single pile through 50MPA rock formation
• Reliability / cycles : Exceeds 2,000 rock bolt pairs
• Water depth : 0 to 22m (current project)
• Power system: Electro hydraulic system
• Data recording: Drilling data, video c/w lighting
• Interface: Fully compatible with dive and grout spread interface
• Deployment: By lifting
Asset name:
