Seaber, the Finnish maritime scheduling software company, and Sedna, the Operating System for Shipping,announced an expanded partnership, introducing an integration between Seaber’s AI-powered optimization engine and Sedna VMS .

The integration addresses one of the longstanding gap s in maritime operations: the handoff between commercial chartering decisions and fleet-wide scheduling. Across COA, TC, and spot programmes alike, schedule quality depends on how quickly commercial data reaches the planning layer.

By feeding live voyage and fixture data from Sedna VMS into Seaber’s optimization engine, customers can pressure-test schedules against real constraints, surface higher-TCE options, and reduce the manual reconciliation that typically sits between chartering and operations.

For most operators, the link between fixing a voyage and optimising a fleet schedule is still manual, and that gap is where value is lost.

The integration addresses persistent pain points that bulk and tanker operators have long managed:

• Schedule updates lag chartering decisions as data moves between systems through spreadsheets and email
• Commercial and operations teams work from different versions of the truth, requiring manual reconciliation
• Optimization opportunities surface too late, limiting fleet-wide gains

By sourcing commercial data directly from Sedna VMS, the integration shortens the path from chartering decision to scheduling action.

The integration delivers measurable improvements for customers using both Sedna VMS and Seaber:

• Scheduling decisions reflect current commercial reality within minutes rather than days
• Optimization runs against live fixture data, exposing higher-TCE alternatives before plans are committed
• Manual reconciliation between chartering and operations is significantly reduced, enabling teams to work from a single, consistent view of the fleet
• Earlier visibility into optimization opportunities supports stronger fleet utilisation and TCE outcomes

By bringing Seaber’s optimization capabilities closer to chartering workflows, the integration enables operators to act earlier on opportunities shown to deliver fleet cost savings of four to six per cent.

“Partnering with Sedna marks a significant step in our mission to make intelligent scheduling the standard in shipping,” said Sebastian Sjöberg, Co-founder & CEO of Seaber. “By connecting Seaber’s optimization engine with Sedna VMS, we are enabling a continuous flow of data from commercial decision-making to operational execution. This is how shipping companies will compete and win in the years ahead.”

Seaber’s platform enables shipping companies and charterers to model scenarios in real time and plan with greater accuracy, supporting improved fleet efficiency, reduced emissions, and stronger commercial outcomes.

“The industry does not need more standalone tools. It needs workflows that connect,” said Bill Dobie, Founder & CEO of Sedna. “By linking chartering decisions with fleet-wide optimization through our integration with Seaber, we are helping customers move from reactive planning to continuous decision-making across their operations.”

The integration is now available for deployment to customers using both Sedna VMS and Seaber, with rollout aligned to each operator’s workflows.
