CTV Drifting Incident
CTV Drifting Incident
A crew transfer vessel (CTV) drifted and hit a nearby structure at 0.5 knots while the crew was completing reporting and administrative tasks.
Prioritizing Admin Over Awareness
Prioritizing Admin Over Awareness
Administrative tasks were prioritized immediately after the crew transfer, leading to a lack of situational awareness.

Study Notes
- A Crew Transfer Vessel (CTV) drifted and hit a nearby structure at 0.5 knots.
What happened?
- A crew transfer from a CTV to a Service Operation Vessel (SOV) was successfully completed.
- The SOV was 180 meters from a wind turbine generator (WTG).
- The CTV moved away from the SOV, and the propulsion controls were set to zero.
- The crew continued to complete reporting and administrative tasks.
- The CTV drifted into and hit the nearby structure at 0.5 knots.
- The CTV Master moved the vessel to a safe area to do hull checks and reporting.
- The WTG asset was inspected and some damage to the paintwork was noted.
- No-one was injured.
What went wrong?
- Administrative tasks were prioritised over situational awareness after the crew transfer.
- The instrumentation on the bridge of the CTV was not set up to warn of an imminent allision.
- Authority had been granted for the crew transfer to take place inside the WTG safety zone.
- The crew transfer should not have been authorised in this location.
Lessons learned
- Resist the temptation to do administrative tasks immediately.
- Maintain alertness, a good lookout, and situational awareness until the vessel is safely located after transfer operations.
- Consider if there is sufficient time to perform administrative tasks and ensure adequate crewing of CTV bridges.
- Work Authorisation should evaluate vessel position relative to fixed assets, wind, and sea conditions.
