Shell Marine has launched a new technical service, Shell Marine Sensor Service (SMSS), an onboard monitoring service that provides real-time insights into oil and equipment condition, helping shipping operators improve vessel uptime and operational resilience.The new service acts as a “digital deckhand,” continuously monitoring oil condition to help crews manage and maintain equipment across a vessel proactively to prevent unplanned downtime.Designed to detect maintenance issues early, SMSS allows crews to act on them before they become critical.
