[Tweet](https://twitter.com/share) ![3479_190_small](https://blog.porthouston.com/hs-fs/hubfs/3479_190_small.jpg?width=618&name=3479_190_small.jpg) ***Caption: Port Houston container terminal truck gates.*** Port Houston recently executed a successful technology upgrade to NAVIS N4, a terminal operating system that optimizes planning and management of container and equipment moves at the port’s container terminals. The system is used for daily operations that include road, vessel, yard planning, billing and reporting. Port Houston upgraded from version N4 2.6.34 to version N4 3.6.9, which required new infrastructure. The upgrade was performed by Port Houston’s technology, operations and IT personnel over a weekend after months of preparation and testing. With this advancement, Port Houston aims to improve and maintain a competitive edge consistently with business and technology innovations. “The project’s success was a collaboration of efforts put forth by multiple departments,” said Port Houston Terminal Operating Systems Manager Mayra Ruiz. “The NAVIS upgrade will allow us to capitalize on new technologies and industry development.” The upgrade embodies Port Houston’s goal of becoming America’s distribution hub for the next generation by providing increased support and scalability for customers. Further, the program adds improved security and operational performance with new features and functions. Port Houston will continue to take the necessary steps to equip the business for the future and provide value-added services to our clients as upgrades are continued throughout the organization.
