Shipping giant Maersk has launched a new Demurrage & Detention (D&D) calculator designed to help importers precisely track their free storage periods and avoid unnecessary additional charges. The tool currently calculates only demurrage and detention fees, excluding storage costs that may apply after 72 hours at port.
How to Use the Online D&D Calculator
The step-by-step process for accessing and using the new tool:
- Log in to Maersk's website: Access your Hub Dashboard through the official Maersk portal.
- Access the calculator: Locate the "Import Demurrage & Detention" widget, enter your bill of lading number, and click "View details."
- Calculate fees: Select the "Detention" tab to view the last free date. By entering your anticipated empty container return date, the system automatically computes potential charges.
- Request extension: If needing additional free days, check the "offer acceptance box" after selecting desired extension days and click "Purchase detention days."
- Confirm purchase: Successful transactions generate a green confirmation banner, with invoices following subsequently.
Understanding Demurrage vs. Detention
Demurrage applies when containers remain at port or yard beyond allowable free time, charging for space occupation that impacts terminal efficiency. These fees incentivize prompt cargo retrieval.
Detention occurs when shippers exceed free usage periods without returning empty containers to designated locations. These charges encourage timely equipment circulation back into carrier fleets.
While both fees aim to optimize container turnaround, demurrage addresses port space utilization while detention focuses on equipment availability.
Strategies to Minimize D&D Charges
- Advanced planning: Coordinate pickup and return schedules before cargo arrival.
- Proactive communication: Maintain regular contact with carriers and forwarders regarding shipment status.
- Process optimization: Streamline documentation and physical handling procedures.
- Tool utilization: Leverage the D&D calculator for accurate time and cost projections.
- Extension purchases: Consider buying additional free days when delays appear unavoidable.
The Complexity of D&D Calculations
Multiple dynamic factors influence final D&D assessments:
- Varying carrier policies on free periods and rate structures
- Local port regulations affecting storage timelines
- Specialized cargo requirements (reefers, hazardous materials, etc.)
- Seasonal port congestion during peak shipping periods
- Contractual terms between shippers and ocean carriers
Maersk's calculator aims to simplify this multifaceted evaluation process through automated computation based on current operational parameters.
Future Enhancements
The carrier plans subsequent calculator upgrades including:
- Integration of port storage fees beyond 72 hours
- Customized solutions based on individual shipping patterns
- Real-time policy updates reflecting current market conditions
The development reflects Maersk's broader initiative to increase supply chain transparency through digital tools that help shippers manage costs and operational timelines more effectively.
