Programme overview
Introduction:
ROV operations and subsea IMR, covering work-class vehicles, CP surveys and campaign planning, is a 1-week course for asset integrity and marine operations units that ends with a Subsea IMR Campaign Plan for a case organisation. Operators lose vessel days, inspection coverage and integrity evidence when ROV spreads, tooling and survey scopes are specified loosely and anomaly data arrives late or unusable. Nominees already manage subsea inspection scopes or ROV service contracts, and learning is by case study on survey reports, CP data sets, vessel schedules and anomaly registers. CoreConcept Training Center delivers this ROV operations and subsea IMR course.
Course Objectives:
- Select the ROV class, AUV or resident drone suited to each inspection and intervention task on pipelines and subsea structures
- Specify tether management, launch and recovery arrangements and tooling for an ROV spread against IMCA ROV guidance and ISO 13628 interface requirements
- Define inspection scopes using general visual, close visual, CP potential, UT thickness and flooded member detection methods
- Interpret CP survey and anomaly data to rank integrity findings and set repair priorities
- Plan intervention tasks, DP vessel spreads and campaign schedules that control weather downtime and vessel days
- Produce a Subsea IMR Campaign Plan that sets scopes, vehicles, vessel spread and reporting rules for a case organisation
Target Audience:
- Asset integrity units responsible for subsea pipeline and structure inspection programmes
- Marine operations units responsible for vessel, ROV and survey spreads offshore
- Subsea engineering units responsible for intervention and repair work packs
- Contract management units responsible for ROV and IMR service agreements
- Corrosion control units responsible for anode condition and cathodic protection survey data

Why Attend This Course:
- Deliver a Subsea IMR Campaign Plan for a case organisation to the asset integrity manager and the marine operations lead for approval
- Decide which vehicle class, tooling and vessel spread each inspection or repair task warrants before services are tendered
- Avoid lost vessel days, incomplete inspection coverage and late anomaly reporting caused by loose scopes and unchecked contractor data
- Share inspection coding sheets, CP data checklists and campaign scheduling templates with integrity and marine colleagues
Conclusion:
Back at work, the participant gives the asset integrity manager and the marine operations lead a Subsea IMR Campaign Plan that sets inspection scopes, vehicle classes, tooling, vessel spread and anomaly reporting rules for the organisation's subsea assets. Contracts staff use it to tender ROV and vessel services, and integrity engineers use it to accept or reject survey deliverables. After the first campaign under the plan, the unit should compare achieved coverage, vessel days, weather downtime and anomaly closure against the plan and revise it.
Frequently Asked Questions (FAQ):
What should participants know before the ROV operations and subsea IMR course?
Participants should already handle subsea inspection scopes, integrity data or ROV and vessel service contracts. No ROV pilot qualification is needed. An anonymised inspection report, CP survey data set or campaign schedule from their organisation helps during the case work.
How does ROV operations and subsea IMR differ from a commercial diving or subsea pipeline design course?
This course covers the remote vehicles, inspection methods and campaign planning used to keep installed subsea assets fit for service. Diving courses manage divers and their safety, and pipeline design courses size and install new lines rather than inspect and repair them.
Why do ROV operations and subsea IMR campaigns rely on cathodic protection surveys?
Cathodic protection surveys show whether sacrificial anodes still hold submerged steel at a protective potential. Readings against a reference electrode, with anode depletion estimates, tell integrity engineers where corrosion risk is rising and where retrofit anodes are needed.
What do participants take back from the ROV operations and subsea IMR course?
Participants take back a Subsea IMR Campaign Plan for a case organisation, with a vehicle class selection worksheet, an inspection scope, a CP data review, a vessel spread choice, a campaign schedule and anomaly reporting rules.
