The Business

Total Terminal International Algeciras S.A.U. (TTI Algeciras) is the second container terminal of the Port of Algeciras Bay, which is located on the Phase A plot of the Isla Verde Exterior expansion area. The terminal consists of a 650-meter-long berths that can accommodate up to 14,000 TEU class vessels, and 16 blocks that run perpendicular to the quay. It is equipped with 8 Quay Cranes, 32 Automated Stacking Cranes and 20 Shuttle Carriers.

The Challenge

Port of Algeciras received attention due to its geo-political advantages in Asia/Northern Europe trade and North America/Mediterranean trade. As vessels can call additionally without deviation to transport T/S cargoes, the port could become T/S hub for the ports of West Africa and the Mediterranean. Despite these advantages, the terminal of the port had extra burden to provide high productivity and competitive stevedoring charges to attract the liners. Promoted by Hanjin Shipping, the selection of TTI Algeciras terminal layout and CHE was made possible thanks to long-time accumulated experience of Hanjin Shipping – TTI Algeciras – CLT for terminal automation.

Given the situation, the container handling equipment selected are Single trolley STS with twin spreader (OCR supported to remove tally operation), Automated Stacking crane and Straddle carrier for horizontal transports.

In 2008, the most difficult decision was whether to introduce shuttle carrier. AGV was excluded because this expensive equipment cannot ensure operation productivity due to its dependency on other container-lifting CHE. Unmanned shuttle Carriers were excluded as well due to its unproven technology.

After the decision, the parties worked on the plans to automate the shuttle carrier to be deployed, preparing for future release of fully automated shuttle carriers.

The Solution: Semi-Automated Shuttle Carrier

Because the shuttle carrier has developed as semi-automated shuttle carrier to take advantage of the technical development in the future, all related processes should be automated except for driving, picking-up and landing which will be automatically conducted by robotized shuttle carrier.

The OPUS Terminal TLC module is core operation module which creates just-in-time job orders by integrating information from all terminal subsystems including workload of CHE. The relevant information for automated process of semi automated shuttle carrier is gathered, monitored and controlled by GCS sub-module which controls information from sensors, RTLS, PDS, and DGPS.

Straddle carrier drivers do not operate anything manually on VMT, and information needed for the job operation is sent automatically, preventing drivers from making mistakes. CLT managed the integration project in which it integrated TOS with sub systems by 3rd party.

The Benefit

All the job orders for CHE within a terminal are created, monitored, and changed in TLC module provided by OPUS Terminal. Regardless of automatic/manual processing, TLC module controls jobs on the subsystems to secure the optimal performance, allowing the successful completion of one or the least possible number of jobs. Therefore the change for automated CHE operation from manual operation shall be accomplished only by changing configuration of OPUS Terminal.

This approach enables the automated CHE suppliers to focus on their core competences, which is the automation, rather than worrying about various terminal operation issues, increasing the possibility of project success.

OPUS Terminal’s TLC module and its component sub-modules for each CHE are provided in open architecture, so that CLT is providing the possibilities to develop advanced functions or apply the modules developed by 3rd party vendors in the future easily, if required. How to control logistics in the comprehensive view, and which CHEs will perform horizontal transportation will be discussed with LGPL in consideration of the level of distributed traffic control algorithm of the supplier and the working relationships with other automated CHE suppliers.
