Zelim’s Zoe technology records a 10-second clip of the person overboard incident
ATTENTION, PERSON OVERBOARD!
How an intelligent detection system on a jack-up rig provides automated person overboard detection and alerts

orkers on offshore rigs have to contend with severe weather and rough seas,
and ensuring their safety in these conditions is a key concern for oil and gas operators. Although accidents such as falling overboard are infrequent, they remain a potential risk. To prevent such incidents, one of the world’s largest offshore rigs in the North Sea, the Valaris Stavanger, has adopted an AI-powered system from solutions company Zelim that automatically detects and tracks persons overboard at sea.

AN INTELLIGENT AI SOLUTION Called Zoe, Zelim’s solution is a person in water (PIW) technology that helps search and rescue operations in the ocean. It uses a suite of cameras and sensors to monitor the area around a vessel, raising alerts if someone falls overboard. Zoe was deployed on the jack-up
rig Valaris Stavanger in February this year, and installed a tailored solution that included seven infrared and optical cameras placed around the vessel, allowing the entire rig to be monitored. Following an initial
trial period, Valaris will evaluate the suitability of the system for use on other assets in their fleet. “The harsh weather in the North Sea
can change quickly. Traditionally if someone falls into the water, the alarm is raised, and a person acts as a spotter to maintain visual contact. We have been totally reliant on line of sight,” Glen Spearman, offshore installation manager onboard Valaris Stavanger, explains. “However, now Zoe gives us a 360-degree view from the rig at any one time. It will reduce our response time and improve the chances of a successful rescue in the event of an accident.”
