2019Maritime emissions monitoring and AI-powered fleet optimization platform.
SailPlan Mariner is an AI fleet intelligence agent that continuously monitors sensors across every vessel in a fleet, ingesting propulsion, HVAC, electrical, and voyage data to detect degradation before annual inspections catch it. The agent performs automated data-quality passes that exclude disconnected or physically impossible readings, then delivers parts-level diagnostics such as refrigerant-side HVAC faults, hull fouling inferred from shaft torque-per-knot drag, and voyage inefficiencies like idle-then-sprint scheduling.
Mariner deploys via a DNV type-approved SailPlan Edge Processor with a 90-day onboard TimescaleDB window, local anomaly detection, Grafana engine-room dashboards, and daily compressed shore summaries when satellite links are available. Shore-side LLM analysis runs on aggregated fleet data while vessels retain autonomous monitoring if connectivity drops, covering predictive maintenance, voyage optimization, and environmental correlation across propulsion, hotel load, and itinerary performance.
Commercial marine operators face accelerating pressure to cut fuel burn and emissions while maintaining schedule reliability across aging fleets with inconsistent sensor quality. Regulatory frameworks including IMO CII ratings, EU ETS maritime coverage, and customer Scope 3 reporting are pushing owners toward continuous operational data rather than annual inspections alone.
Mariner-style fleet intelligence sits at the intersection of predictive maintenance, voyage optimization, and emissions compliance — markets projected to expand as operators digitize machinery monitoring and shore-side analytics. Edge-first architectures that function during satellite outages, combined with AI diagnostics that translate messy telemetry into parts orders and maintenance timing, are increasingly valued as fleets seek measurable ROI from decarbonization investments.
SailPlan differentiated through high-frequency machinery and operational data capture designed for harsh marine operating environments, including cruise, naval, and offshore deployments. Its Mariner AI agent translated sensor anomalies into actionable maintenance signals rather than raw telemetry dashboards.
The platform integrated emissions compliance reporting with predictive maintenance and voyage optimization in a single fleet-wide system. Partnerships with ABS and anchor deployments with Harvey Gulf provided class-society credibility and operator validation that many maritime software startups lacked.
