Mainsail is a terminal operating system (TOS) that helps marine terminals manage cargo, inventory, vessel activity, and gate operations from a single platform. Designed for container, RoRo, and general cargo, Mainsail provides real-time visibility, streamlined workflows, and integration with terminal technologies and business systems to improve operational efficiency.
Built as a flexible platform, not just a product, Mainsail scales to remain in lockstep with terminals as their needs and requirements evolve.
Every terminal operates differently. Mainsail provides the flexibility to support the needs of marine terminals across different sizes, cargo types, and operating environments. Today, Mainsail supports terminal operations handling more than 20 million TEUs and 14 million gate transactions annually.
Evaluating your next TOS?
Tideworks can generate better and more granular data for analytics, which can help you improve operational decision-making. Tideworks can now scale to handle larger loads and multiple terminals more efficiently, directly reducing expenses for customers with economies of scale.
By creating a proprietary billing engine separate from the TOS, Tideworks can now establish centralized management of billing contracts of rates, tariffs, invoicing, etc. to expand billing capabilities from the terminal to the corporate level.
