There is an increasing pressure on refineries and terminals to reduce their operating costs and demurrage is often a significant and highly visible expense. Most installations track the total figures and analyse its causes and makeup. OAS provides rich support for demurrage estimation, tracking and visualisation which results in a considerable reduction in manual calculations. Demurrage forecasts are calculated utilising the comprehensive data already captured within the OAS shipment accounting process and by examining key events in the vessel’s timesheet.

• Flexible rule-based definition of allowable laytime, conditional allowances and start of laytime.
• Contracted laycan start and end dates recorded.
• Disciplined entry of timesheet events and delays.
• Supported by rules defining acceptable times between mandatory events.
• Requires delay entry if rules exceeded, giving immediate focus on operational efficiency - pro-actively tackling issues, rather than reactive once demurrage problem occurred.
• Agent and Inspector timesheets can also be collected to support demurrage investigations.
• Initial estimate of demurrage calculated automatically on shipment completion.

• Entry of claims and, ultimately, settlement invoices (with posting to cost centres) against original demurrage estimates from timesheets\delays.
• Capture of individual transaction events build to performance reports, graphs, and KPIs on vessel performance, port performance, demurrage summaries, demurrage accruals.
• OAS Explorer gives graphical representation of jetty schedule to aid improved planning and optimisation of harbour activity.
• Variety of colour keys on schedule Gantt chart includes demurrage rate, estimated demurrage cost, historical demurrage costs.
• Drag and drop functions allied with broad constraint checks and definition of product availability at berths lead to better decision-making in initial planning.
