Background:Where did we start….?
4
Design PhaseScope:
• Design and fabrication of the subsea rig • Design and build of top-side control system• Design and fabrication of the CO2 injection pipe• Factory Acceptance Testing of the fully integrated system• Dock (submerged) Testing including injection pipe installation in seabed • Provide Operational Spares• Provide Operator Training• Provide Offshore operations support
5
Design PhaseInitial concepts – subsea module (2015):
CISPipe end
ROV Panel
CO2 / Waterflexible pipe
Pre-formed push pipe
Hydraulic pipe Drive motors
Ballast
Embedment features
• ROV intervention to operate rig• Rig remains on seafloor during CO2
injection
6
Design PhaseInitial concept – subsea module (2018):
Frame
Pre-formed push pipe
Hydraulic power unit
Embedment features
Hydraulic pipe Drive motors
Ballast
• No ROV operations Panel• Now integrated subsea power
and comms• CO2 injection to be from
separately deployed source• Rig to be recovered between
pipe installations/during CO2injection
7
Design PhaseFinal concept – subsea module (2018/19):
Frame
Push pipe guide mechanism
Hydraulic power unit and controls
Embedment features
Hydraulic pipe Drive motors

Design PhaseChallenges:• CO2 pipe injection method:
• Curved pipe geometry• Precise positioning in seabed• Connection of external CO2 supply• Capability to insert and retract pipe • Verification of pipe diffuser position following pipe insertion
• ‘Stuck Pipe’ Scenarios:• Rig breakdown/power failure with pipe partially inserted• Pipe refuses during insertion• Pipe bends/jams during pipe insertion due to ground conditions
10
Design PhaseChallenges:• CO2 pipe injection method:
• Realtime pitch and roll monitoring during rig land out and operations (accelerometer)
• AHRS for heading reference during land out• COTS linear engine utilized for pipe
injection – bi-directional and marinized
