💡 Accountant's Note
Vessel operating expenses (OpEx) are the daily cost of running a vessel — independent of whether the vessel is earning revenue or not. OpEx components: (1) CREW: the largest single OpEx item — officers and ratings wages per their collective bargaining agreements (typically $8,000–15,000/month per crew member × 20-25 crew = $200,000–350,000/month). Crew costs are heavily influenced by flag state (Marshall Islands vs. Cyprus vs. Panama flags have different regulatory requirements), nationality mix (Filipino ratings are cheaper than European; Greek officers command premium rates). (2) INSURANCE: H&M (hull and machinery — for physical damage) plus P&I (third-party liability). (3) MAINTENANCE: routine and planned maintenance, unplanned repairs. (4) SHIP MANAGEMENT FEE: if the vessel is managed by a third-party manager (V.Ships, Columbia Ship Management, Synergy Maritime) — typically $10,000–20,000/month. (5) STORES AND SPARES: consumables and critical spare parts inventory. Daily operating cost per day (OPEX/day) varies from $5,000/day (small coastal vessels) to $30,000+/day (large VLCC tankers or LNG carriers).
Practitioner & Systems Framework
💻 ERP Architecture
Vessel operating expenses are tracked at the vessel level in the ship management system. Each vessel has a monthly operating budget — actual vs. budget variance analysis drives management attention. Crew costs require tracking in compliance with MLC 2006 (Maritime Labour Convention) — crew wages, rest hours, repatriation rights, medical coverage, and unemployment insurance must all be documented. Third-party ship managers provide monthly management accounts (vessel OpEx by cost category) — these are the primary input for the shipowner's vessel-level P&L.
⚠️ Audit Flags
OpEx auditing tests: (1) Crew costs — payroll records matching the crew list and the flag state minimum wage requirements; (2) Maintenance costs — routine maintenance appropriately expensed vs. capital improvements capitalized; (3) Insurance premiums — are amounts on the financial records consistent with policy documents? (4) Ship management fees — are they supported by the management agreement? (5) Port state control deficiencies — any regulatory violations noted by port state control inspectors may create remediation costs that should be accrued.
📄 Required Documentation
Crew list and payroll records (by vessel), H&M insurance policy documents, ship management agreement (scope of services, fee structure), maintenance work orders and invoices, port state control inspection reports, stores and spares purchase records, lube oil analysis reports, vessel performance reports (fuel consumption vs. charter party specifications), and monthly vessel operating statement vs. budget.
