Stolthaven Terminals and Systems Navigator improve simulation model library

Published by
Tanks and Terminals,


Stolthaven Terminals in Rotterdam, the Netherlands, have cooperated with Systems Navigator to support a terminal within its portfolio with their strategic decision regarding the jetty line layout. To quantify the impact of terminal improvement initiatives, a simulation model configuration with product-to-product changeover logic, cleaning durations and data driven usage of multiple lines for a parcel transfer is included in Systems Navigator’s extensive model library.

Because of the business need to always improve turnaround times of ships and the condition to maintain the high-quality standards regarding preventing product contamination, the terminal is evaluating the investment in new jetty lines. Next to improved pre- and/or post-pump durations, faster turnaround times can be achieved by faster pumping or by parallel (un)loading operations. When multiple jetty lines can be used to transfer a parcel, the flow rates increase. Therefore, increasing the amount of parcels transfers using multiple jetty line simultaneously is a key part of reducing ship’s turnaround times.

The simulation project was done to evaluate the best jetty line configuration, product allocation to lines and to calculate the expected achieved flow rates and number of product-to-product changeovers.

Main project results

The project results in a thorough understanding of the expected terminal performance with a focus on:

  1. Achieved flow rates for specific products.
  2. Percentage of parcels that were able to be transferred via multiple (2 or 3) jetty lines simultaneously.
  3. Number of product-to-product changeovers required.
  4. Total number of cleaning hours required for all product-to-product changeovers.
  5. Potential operational improvements in shore side infrastructure and corresponding terminal performance increase regarding achieved flow rates.
  6. Tradeoff in operation flexibility versus changeover costs for cleaning.

Bas Verheul, Global Asset Management Director Stolthaven Terminals, said: “Stolthaven makes significant investments in continuous upgrades of our infrastructure. Working with Systems Navigator has helped us to better prioritise our investments and quantify the impact of decisions on our service levels”.

Daan Merkestein, Systems Navigator Senior Consultant, said: “This project was all about getting a grip on the complex infrastructure usage of the simulated terminal. We well succeeded in this, given that we achieved 98% accuracy in the total product-to-product changeovers done”.
