Since 1987, we’ve combined our deep expertise in saturation diving with our industry-leading well intervention capabilities. This unique combination ensures we have the experience to tackle the most challenging subsea hardware. Our capabilities also include subsea inspections and repairs—tasks that require more precision and maneuverability than remotely operated vehicles (ROVs) can provide.
Helix’s well intervention monohull vessels, Seawell and Well Enhancer, are both equipped with integrated 18-man saturation systems, each rated to 300 meters of seawater.
From 2011 to 2025, our diving teams completed 5,532 bell runs and worked a total of 5,0934 days, accumulating over 1,413,328 man-hours in saturation diving.
