Run the port call before you sail. Read every clause like your most senior charterer.
Price the time you'll actually lose
Turnaround and unpaid time from real port events, set against your CP terms, so the exposure sits in your estimate.
Check the constraints before you commit
Vessel dimensions checked against each terminal, with the berth you're most likely to be sent to, before it's ever confirmed.
Catch the risk before you agree
Every clause scored for risk, missing or ambiguous terms flagged, then checked against recap and BIMCO before you sign
Draw on your company's complete history
Draft from a searchable library of your approved wording and counterparty variations, with risk-flagged terms surfaced. Gets smarter with every fixture
Carry agreed terms to the master
Agreed terms become structured handover instructions and master-ready voyage orders, each linked back to its source clause.

Frequently Asked Questions
- Marcura helps chartering teams assess the assumptions and terms behind a fixture. PortLog strengthens estimates of port costs, turnaround and unpaid time. Contract Intelligence supports charter party review, negotiation, drafting and handover. Use either capability independently or both to bring a clearer view of costs and contractual exposure into the commercial decision.
- Underestimate port costs or unpaid time and the fixture may deliver less than expected. Allow too much and your freight rate may become less competitive. PortLog helps assess both risks using historical port performance. PortLog Pro adds terminal-level modelling of laytime, demurrage, despatch and port costs to show the financial effect of different assumptions.
- PortLog combines digitised Statements of Facts, agent data, disbursement-account information, AIS and weather data. Records are cleansed, standardised and anonymised to support terminal-level comparisons, including at ports your fleet rarely calls.
- Contract Intelligence supports the process from initial review through to operational handover. It flags missing, ambiguous or conflicting terms, supports drafting, redlining and version control, and checks the charter party against the recap and applicable BIMCO standards. Agreed terms can then become clause-referenced handover instructions and master-ready voyage orders.
- Yes. A customer-specific clause library holds approved wording, counterparty variations and known clause risks. The knowledge base draws on your charter party history and trading patterns, helping teams apply company standards during review and drafting. Experience remains available to the team as the library develops.
- Contract Intelligence uses a customer-specific knowledge base. Your charter parties, negotiated wording and trading history remain confidential and separate from other customers’ knowledge bases. They inform your company’s reviews rather than becoming shared industry intelligence. This private contract knowledge is distinct from PortLog’s wider anonymised port dataset.
- PortLog connects with supported voyage management systems, bringing port time and cost estimates into voyage calculations. Compare them with existing assumptions and see the financial impact of differences. Contact us to confirm the integration available for your VMS.
- Actual port costs, time in port and laytime outcomes provide evidence for future estimates. Approved wording, counterparty variations and risks identified during contract review build company knowledge. Settled claims add context on where exposure arose, helping chartering teams apply previous experience to the next estimate and negotiation.
