About VoyBulk
Free voyage estimation tools built by dry bulk shipping professionals — for shipowners, charterers, and brokers.
What Is VoyBulk?
VoyBulk is a free online platform that gives dry bulk shipping professionals the tools they need to evaluate cargo fixtures, calculate laytime, look up sea distances, and track vessel positions — all without spreadsheets, desktop software, or credit cards.
The platform was built to solve a real gap in the market: professional-grade voyage calculation software has historically cost $200–2,000 per year and required installation on a single machine. VoyBulk offers the same core functionality in any browser, free to get started.
Who Uses VoyBulk?
VoyBulk is designed for professionals working in dry bulk chartering:
- Shipowners evaluating cargo enquiries against vessel operating costs
- Charterers comparing freight rates and voyage alternatives before fixing
- Ship brokers running quick estimates to advise principals on fixture viability
- Operators tracking laytime, managing cargo orders, and monitoring fleet positions
- Developers integrating sea distance data via the VoyBulk Port Distance API
The tools handle all major dry bulk vessel sizes from Handysize (10,000–35,000 DWT) through Supramax, Ultramax, Panamax, Kamsarmax, and Capesize (100,000+ DWT).
The Tools
Voyage Estimator & TCE Calculator
Full voyage P&L including bunker costs (VLSFO, MGO, ULSFO), port disbursements, canal dues, broker commissions, and cargo intake. Outputs TCE, voyage profit, and a full cost breakdown. Sensitivity panel shows how changes in freight rate, bunker price, speed, or port days affect returns in real time.
Laytime & Demurrage Calculator
Parses Statement of Facts (SOF) documents to compute laytime used against allowed laytime under charter party terms (SHINC, SHEX, FHEX, CQD, PWWD). Calculates demurrage payable or despatch earned automatically.
Port Distance Calculator
Sea distances between 6,700+ ports worldwide using graph-based pathfinding calibrated against industry-standard routing data. ECA/SECA zone detection with automatic VLSFO/MGO cost split. Canal routing options for Suez, Panama, and Kiel. Piracy High-Risk Area avoidance available.
Vessel Position List
AI-powered parsing of position email updates (including Gmail integration) to extract vessel name, open port, date, and cargo capacity. Displays open fleet positions on an interactive map for fast cargo matching.
Cargo Order Management
Organise voyage charter and time charter trip enquiries by region. Track laycan windows, load and discharge ports, freight rates, and fixture status across your cargo book.
The Company
VoyBulk is developed and operated by a team based in Dubai, United Arab Emirates, with hands-on experience in dry bulk chartering operations. That is why the tools are built around the workflows that shipowners, charterers, and brokers actually use — not generic financial modelling templates.
The platform is hosted in the EU and accessible to users worldwide. No credit card is required to sign up.
