• Depth: shallow diving in the tidal zone.
• Involved excavation in loose gravel to expose and remove the bolts, while in the impact zone, further the construction of a temporary access road was necessary to enable the lifting of the valve.
• After 8 months, when replacement valves were ready, further excavation was required.
• The original valve was replaced with 3 smaller valves, which require ongoing maintenance.
