What Tideworks Technology does

Tideworks Technology, founded in 1999 and headquartered in Seattle, is a private enterprise software company that builds Terminal Operating Systems (TOS) for marine container terminals and intermodal rail facilities. The company originated as the internal IT arm of SSA Marine (part of Carrix, Inc.), and was acquired by Blackstone Infrastructure Partners in 2024. Tideworks' product portfolio centers on Mainsail (the marine TOS), Intermodal Pro or IPRO (the rail TOS), Spinnaker (planning and execution), Traffic Control (equipment dispatch), Terminal View (digital twin visualization), and supporting applications including GateVision, BUOY, Forecast, and EDI Porter. The platform is built on a configurable, extensible architecture with standardized APIs that supports both AWS-hosted cloud deployments and on-premises installations, and is used at more than 120 facilities globally across marine and intermodal rail operators.

Tideworks generates revenue primarily through term-based software subscriptions and licenses for the TOS platform, supplemented by professional services for deployment, configuration, and training, plus recurring EDI management, cloud hosting, and infrastructure services. Pricing is quote-based with annual or multi-year contract cycles; AI capabilities are embedded within the platform rather than priced separately. The go-to-market is direct enterprise sales, supported by a professional services organization that delivers implementations and a 24/7 support model. Distribution is direct, with a regional channel relationship through the Brenock Technology joint venture covering complementary cloud-based marine management applications.

The customer base includes large enterprise marine terminal operators such as Luka Koper, POMTOC, Crowley Maritime, TOTE Maritime, Florida International Terminal, Oregon Container Terminal, Wallace Investments/Port of Auckland, and Manzanillo International Terminal, as well as Class I intermodal rail operators including BNSF, CSX, and Canadian National. Tideworks has offices in Seattle, Jacksonville, and Panama City, with European operations led from the field. Recent strategic activity centers on cloud modernization (Mainsail 10 on AWS), AI-assisted terminal planning features, and continued product expansion under Blackstone ownership.

Software is sold as a platform rather than standalone line items; AI capabilities are embedded within the broader platform rather than priced separately.
2. Professional Services: Tideworks generates revenue from professional services including project management, system configuration, installation, user acceptance training, and hybrid onsite and remote go-live support during deployments and upgrades.
3. EDI and Integration Services: Revenue generated from EDI management, translation services (EDI Porter), and ongoing data exchange infrastructure supporting terminal operations.
4. Hosting and Infrastructure Services: Revenue from cloud hosting services (AWS-based), EDI management, and IT infrastructure support services that keep terminal systems running.

Scale indicators6 records

Recent moves7 records

Expansion highlights5 records

Direct peers

• Navis (Kaleris): Navis, now part of Kaleris (Accel-KKR portfolio), is the historical market-leading terminal operating system for ocean carriers and marine terminals. It is the most direct competitor to Tideworks' Mainsail platform across container terminals worldwide, and several Tideworks executives were recruited from Navis.
• INFORM GmbH: INFORM provides terminal operating systems and yard management software (YMS) for container terminals, ports, and intermodal facilities. Its TOS and optimization portfolio competes head-to-head with Tideworks' Mainsail and Intermodal Pro across European and global terminals.

Broad incumbents

• ABB Marine & Ports: ABB offers automation, electrification, and digital solutions for marine terminals and ports as part of a much broader industrial portfolio. While not a direct TOS vendor, it competes with Tideworks at the automation and equipment-control layer where Tideworks' Traffic Control and Spinnaker operate.
• Konecranes / Cargotec (Kalmar): Konecranes and Kalmar (now part of Cargotec / MacGregor ecosystem) supply automated cranes, yard equipment, and equipment-control software for container terminals. Their equipment-side software competes with Tideworks' Traffic Control and equipment dispatch capabilities.

Emerging players

• Cavotec (including previously listed MoorMaster): Cavotec provides automation and electrification equipment for ports and terminals, including mooring, shore power, and gate automation. It overlaps with Tideworks in gate automation and equipment-control niches, particularly for terminals investing in electrification and automation.
• Camco Technologies: Camco Technologies provides gate automation, OCR/RFID-based identification, and terminal automation solutions. Its gate and OCR products overlap with Tideworks' GateVision and integrated OCR/RFID capabilities at the terminal perimeter.

Others

• DP World (terminal operating arm): DP World is one of the world's largest terminal operators with in-house developed terminal technology stacks and operations. While primarily a customer-type operator, its internal digitization efforts and selective technology partnerships make it an adjacent reference point for terminal operating software requirements.
• Identec Solutions: Identec Solutions provides RFID, asset tracking, and yard visibility hardware and software for terminals and intermodal facilities. Tideworks' VP of Sales & Marketing came from Identec, and its hardware complements Tideworks' TOS at the equipment and RFID integration layer.
