Summary
An investigation describes C-Rover striking Diamond Ocean Valiant during synthetic-based mud transfer after losing bow-thruster hydraulic power. Wind, current and seas contributed to drifting; a tight stern line was cut and a hull breach was subsequently reported. The report records revised mooring arrangements and a prospective DP2 upgrade.
