Minimising Risk - Maximising Value

NSO - Subsea Integrity & IRM

Subsea Integrity & IRM
NSO-Subsea-Integrity-IRM.jpg#asset:122
Client: Various 
Location: World Wide
Phase: 1 to 5
Year: 2011 - Present
Scope:
SETS have extensive subsea integrity and IRM management experience through supporting a number of operators and tier 1 contractors across a variety of assets utilising rope access, ROV, air and saturation divers
STEP 1, SETS confirm the reported defect nature and verify whether the repair is necessary and economically viable or justifiable.  Inspection and maintenance routine frequencies may require challenge.
STEP 2, Explore inspection and repair options.  SETS convene a risk assessment to identify and quantify risks to the asset and compile decision flow chart(s) to enable mitigations to be engineered and written into procedures to minimise vessel stand-by time.  Outline budgets, schedule and methodologies are proposed.  Deployment methodology may be paramount to project success; selection criteria compiled prior to vendor selection, if frame agreement unavailable.
STEP 3, SETS proposes repair concepts based on possible damage, fabrication and installation timeframes.  Chosen solution(s) engineered and manufactured or procured.  SETS manage equipment and vendor selection processes.  Operational risk assessments and procedures can be produced.  Management of tooling and integration testing may be necessary.
STEPS 4, SETS actively manage the processes described above to commence offshore operations within project constraints.  SETS supervise offshore operations to ensure efficient inspection, repair or maintenance whilst keeping client management fully aware of progress and involved in decision making.
STEP 5, SETS close the project out by completing the scope on time and within budget.  Lessons are learnt to be applied to subsequent projects.  Records revised to reflect repairs completed and defects found.  Integrity management documentation revision may be necessary.
Key Challenges :
·         Limited information on subsea assets in some cases
·         Limited access to defect locations: subsea
·         Short time frames.
