Core Features
Maress turns vessel-generated operational data—augmented with relevant external datasets—into decision-grade metrics on fuel use and emissions. Its MRV Reporting Module supports voyage validation and the secure transfer of checked data to verifiers via DNV’s Veracity, helping teams align EU MRV/EU ETS reporting with day-to-day operations. Its key features include:
Real-time fleet & vessel insight: Live overviews for each vessel and the whole fleet enable continuous energy-efficiency tracking and awareness across the organization.
MRV Reporting module + Veracity: Validate voyages, keep documents in one place, and send quality-checked MRV data directly to DNV’s Veracity for efficient verification and EU workflows.
Data validation & auditability: Built-in validation and data-quality checks minimize verification cycles; BDNs and certificates are centralized to streamline audits.
Cloud connectivity, no hardware: Cloud-based, integrates with leading ship-to-shore/data-collection systems and includes a user-friendly manual input option.
Collaboration & transparency: Designed for owners, charterers, contractors and crews; surfaces the “right information” to the “right people” to coordinate decarbonization.
Analytics modules & APIs: Optional modules cover Fleet Efficiency, Vessel Statistics, Fuel Prediction, Campaigns & Scoreboard, Project and Systems Analytics, plus Mode Detection & Data API.
Closing Insights
VPS positions Maress as a practical engine for measurable decarbonization, pairing software with structured programmes that drive behaviour change. In 2024, the Maress Decarb Summer Campaign engaged more than 300 vessels from 12 companies and delivered over 7,000 tonnes of CO₂ savings during the campaign period, with crews applying measures such as engine optimization and shore power connections; campaign dashboards and coaching supported crews.
For compliance-driven teams, Maress’s MRV Reporting Module and partnership with DNV’s Veracity allow validated voyages and documents to flow directly to verification and provide project/client breakdowns that support EU ETS accounting. A major, North Sea Shipping, notes less time spent on MRV administration when data captured in Maress moves automatically to DNV.
With more than 600 offshore vessels using the platform across PSV, AHTS and other segments, and VPS’s advisory services alongside cloud connectivity, the outlook emphasizes scale: faster verification cycles, clearer collaboration with charterers, and an expanding toolkit of modules (e.g., Project, Systems Analytics) aligned to complex offshore operations.
