EEM Reference Architecture · Fleet & Vessel Operations

Meridian Emergency Event Management across Ship and Shore

Operating model for awareness, activation, and execution of high-consequence maritime events — hurricane evasion, port disruptions, vessel system degradations, medical or security incidents at sea, and fleet-wide advisories. Anchored on a single ServiceNow instance that integrates with existing shipboard and shore systems rather than replacing them. EmergencyWatch handles signal monitoring and stakeholder communications across the fleet; EmergencyAct drives plan governance, work packages, and coordinated execution between ship and shore.
