ATSBE (All Time Saved Both Ends)

ATSBE stands for "All Time Saved Both Ends," a term used in charter party agreements to denote the total time saved during the loading and unloading processes at both the departure and destination points.

Understanding the Term "ATSBE (All Time Saved Both Ends)" in Shipping and Logistics

Definition of ATSBE

ATSBE stands for "All Time Saved Both Ends," a term used in charter party agreements to denote the total time saved during the loading and unloading processes at both the departure and destination points. It involves calculating time efficiencies gained against the stipulated laytime, which is the allotted period for loading and unloading operations under a charter agreement.

Importance of ATSBE in Charter Parties

1. Cost Efficiency: By emphasizing time saved at both ends of a voyage, ATSBE directly influences the cost structure of shipping operations. Time efficiency translates into cost savings for either the shipowner or the charterer, depending on the specifics of the charter agreement.

2. Operational Efficiency: ATSBE encourages both parties to optimize operations, leading to quicker turnaround times for vessels, which can significantly enhance operational flow and reduce port congestion.

3. Flexibility in Operations: Recognizing time saved at both ends allows for greater flexibility and efficiency in logistics planning and operations, contributing to more reliable and predictable shipping services.

Application and Calculation of ATSBE

ATSBE is applied within the context of dispatch and demurrage calculations. Dispatch refers to a reward paid to the charterer when operations are completed before the agreed laytime, whereas demurrage is a charge for exceeding this time. The use of ATSBE allows for the comprehensive acknowledgment of time saved during the voyage's critical operational phases:

1. Dispatch Considerations: If the actual time used for loading and unloading is less than the allocated laytime for both processes, the charterer may be eligible to receive dispatch payments based on the ATSBE calculation. This serves as an incentive for efficient operations.

2. Equitable Adjustments: ATSBE can be used to adjust financial responsibilities equitably, ensuring that savings achieved through efficiency are appropriately recognized and compensated.

Factors Influencing ATSBE

Several factors can contribute to achieving time savings, thus positively impacting the ATSBE:

1. Operational Efficiency at Ports: The proficiency of port operations, including the speed of loading/unloading procedures and the effectiveness of logistics and coordination, significantly affects ATSBE.

2. Crew Performance: The skill, experience, and efficiency of the vessel's crew play a vital role in optimizing operations and minimizing laytime usage.

3. Technological Support: Advanced technologies for cargo handling, vessel loading strategies, and real-time coordination can reduce operational times substantially.

Managing and Optimizing ATSBE

To maximize the benefits of ATSBE, shipping companies and charterers may adopt various strategies:

1. Pre-Planning: Detailed planning of loading/unloading operations, including resource allocation and scheduling, to minimize delays and inefficiencies.

2. Real-Time Communication: Maintaining open lines of communication between the vessel, port authorities, and on-ground logistics teams to swiftly address any potential issues.

3. Continuous Improvement: Analyzing performance data to identify trends, bottlenecks, and areas for improvement in operations to enhance future ATSBE outcomes.


ATSBE (All Time Saved Both Ends) is a key term within charter party agreements that underscores the critical importance of time efficiency in shipping operations. By focusing on time saved during loading and unloading at both the departure and destination ports, ATSBE provides a comprehensive measure of operational efficiency. Its effective management not only ensures cost savings but also promotes smoother, more reliable shipping operations, benefitting all parties involved in the maritime logistics chain.
