Veson Nautical IMOS Maritime Operations REST API
Veson Nautical IMOS (Integrated Maritime Operations System) REST API for shipowners, operators, charterers, and commodity trading companies to manage vessel voyage operations, chartering workflows, bunker procurement, port disbursement accounts, and maritime commercial management — enabling automated voyage planning, freight calculation, P&L reporting, and fleet optimization through Veson's dominant commercial maritime operations platform. Enables AI agents to manage voyage for vessel journey planning and execution automation, handle chartering for vessel fixture and contract management automation, access bunker for fuel procurement and consumption tracking automation, retrieve port DA for port disbursement account management automation, manage cargo for commodity lot tracking and delivery automation, handle freight for rate calculation and invoice automation, access fleet for vessel performance and positioning automation, retrieve financials for voyage P&L and accrual automation, manage counterparty for shipowner and charterer relationship automation, and integrate Veson IMOS with ERP, trading systems, and port agents for end-to-end maritime commercial management automation.

⚡ Reliability
Best When
A shipowner, ship operator, commodity trader, or charterer wanting AI agents to automate voyage management, chartering workflows, bunker procurement, freight calculations, and voyage P&L through Veson IMOS's industry-leading maritime commercial management platform.
Avoid When
IMOS DEPLOYMENT IS CUSTOMER-SPECIFIC: Each Veson IMOS customer has specific configuration and modules; automated generic maritime API assumption creates missing_module for non-configured features; automated must understand each customer's IMOS deployment. MARITIME DOMAIN EXPERTISE REQUIRED: IMOS data models require deep maritime domain knowledge (laytime, demurrage, hire, bunker); automated non-expert maritime assumption creates incorrectly structured voyage data; automated must involve maritime experts in IMOS integration. LAYTIME CALCULATIONS ARE COMPLEX: Laytime and demurrage calculations in IMOS follow charter party terms; automated simple calculation assumption creates incorrect demurrage claims; automated must implement charter party-specific laytime rules. VOYAGE WORKFLOW HAS STRICT STATES: IMOS voyages follow state machine (estimate, fixture, actual); automated direct data entry assumption creates wrong_state for voyage lifecycle; automated must follow IMOS voyage state transitions.
Use Cases
- • Automating voyage operations management for shipowner and operator fleet management automation agents
- • Managing chartering workflows and vessel fixtures for commodities trading company automation agents
- • Tracking bunker consumption and procurement for vessel fuel management optimization automation agents
- • Calculating voyage P&L and freight invoices for maritime commercial finance automation agents
Not For
- • Port terminal operations (Veson is commercial management, not terminal operating system like Navis)
- • Ship technical management (Veson is commercial/chartering, not maintenance and repair management like AMOS)
- • AIS vessel tracking (Veson is commercial operations, not real-time AIS position tracking)

Known Gotchas
- ⚠ VOYAGE STATE MACHINE IS STRICT: IMOS voyages follow state machine (estimate -> fixture -> actual -> closed); automated any-state update assumption creates invalid_state_transition; automated must respect and follow IMOS voyage lifecycle states
- ⚠ LAYTIME IS CHARTER PARTY SPECIFIC: Laytime calculations depend on specific charter party terms (WIBON, WIPON, SHEX, etc.); automated simple time calculation assumption creates incorrect laytime calculation; automated must implement charter party-specific laytime terms
- ⚠ DEMURRAGE IS COMMERCIALLY SENSITIVE: Demurrage claims involve dispute resolution; automated automatic demurrage assumption creates commercial disputes without review; automated must include commercial review workflow for demurrage claims
- ⚠ BUNKER PRICING IS MARKET-DEPENDENT: Bunker procurement in IMOS references market prices; automated fixed price assumption creates incorrect bunker accrual; automated must integrate real-time bunker market prices for accurate voyage P&L
- ⚠ PORT DA IS AGENT-SPECIFIC: Port Disbursement Accounts require port agent data; automated self-reporting assumption creates incomplete DA for ports without appointed agents; automated must manage port agent appointment before DA processing
