Subsea7 reports 35 extra operating days on Seven Vega

Subsea7 says its 4Insight software helped Seven Vega operate for around 35 more days in 2025 than its planning assumptions allowed.

Around 35 additional operating days in calendar 2025, over 10% above standard planning assumptions, for one named vessel. These are company-reported operating days, not cash savings or a comparison with the previous year.

Limits: Company-reported result against a planning baseline, without independent outcome validation, matched control, software cost or net ROI. The same group’s supplier case is not independent corroboration. The scope of automated decisions and crew approval is unclear; do not infer uncrewed operation or transfer the result to the fleet, safety, fuel use or group earnings.
