The ROV located the diver task near the limit of safe penetration down a shaft and into a tunnel. The diver followed the umbilical to the work area which was illuminated and monitored by the ROV. After the diver completed the task and cleared the area, the ROV verified all work was complete and moved to locate the next task. Diver effectiveness was greatly increased by maximizing diver bottom time on task completion rather than task location and prioritization.
