How to Log In to Tideworks Terminal Appointment Portal: Step-by-Step Walkthrough

To log in to the Tideworks Terminal Appointment Portal (officially powered by Forecast by Tideworks), visit https://www.tideworks.com/solutions/forecast/, select your destination marine or intermodal terminal, and enter your registered Email Address and Password. Designed for drayage trucking companies, customs brokers, freight forwarders, and steamship lines, Forecast serves as the central customer service and gate scheduling interface for ports running the Tideworks Mainsail terminal operating system. Because each port authority or terminal operator maintains a dedicated operational database—such as Terminal 18 in Seattle, Oakland International Container Terminal (OICT), or POMTOC in Miami—users must authenticate through their specific terminal's subdomain on .tideworks.com or .tideworks.io. Once signed in, dispatchers can book container pick-up and drop-off slots, verify customs and line holds, pay demurrage charges online, and run booking pre-checks to prevent costly turn-backs at the terminal gate.

Required Credentials & SCAC Registration Prerequisites

• Registered Forecast User ID: Your company email address associated with an approved terminal profile.
• Company & Carrier Identifiers: Trucking dispatchers require an active Standard Carrier Alpha Code (SCAC), Uniform Intermodal Interchange and Facilities Access Agreement (UIIA) standing, and valid port-specific truck/RFID tag registrations.
• Cargo & Equipment Reference Numbers: Active container numbers, Bill of Lading (BOL) numbers, or export booking numbers to query inventory or secure gate time slots.
• Browser & Network Readiness: An updated desktop or mobile web browser (Chrome, Edge, or Safari) with TLS 1.2+ encryption and pop-up blockers disabled for generating PDF gate passes and e-receipts.

Scheduling Gate Appointments, Container Lookups & Fee Payments

• Gate Appointment Scheduling & Management: Reserve, modify, or cancel specific time windows for import container pick-ups, empty returns, and export drop-offs to minimize driver gate queues and dwell times.
• Multi-Container Availability & Hold Lookups: Query dozens of containers simultaneously to verify discharge status, customs clearance, freight line releases, yard location, and Last Free Day (LFD) deadlines.
• Export Booking Pre-Check Utility: Validate export booking numbers against the terminal's live Mainsail system prior to dispatching drivers, checking vessel cutoff dates, hazardous cargo restrictions, and equipment type acceptance.
• Online Demurrage & Fee Payments: Calculate accrued storage, reefer plug-in, or terminal handling fees and settle balances immediately using a credit card or a pre-established terminal guarantee account to clear financial holds.
• Automated Watchlists & Email Alerts: Subscribe specific containers or bookings to automated push notifications that alert dispatchers the exact moment a hold is lifted, a vessel arrives, or a gate transaction completes.

Fixing Common Login Errors & Booking Rejections

Account Security & Multi-User Dispatch Hygiene

• 🔒 Verify the Exact Terminal Subdomain: Always confirm the browser address bar ends in an official .tideworks.com, .tideworks.io, or the verified port operator's domain (such as .mitpan.com or .smitco.com.co) with an active HTTPS padlock before entering account credentials.
• 🔒 Eliminate Shared Dispatch Logins: Do not share a single Forecast login across an entire dispatch floor. Provision individual user accounts under your company profile so terminal administrators can audit appointment changes and avoid simultaneous session lockouts.
• 🔒 Protect Online Payment Methods: When paying terminal demurrage or ancillary gate fees online, never save corporate credit card numbers in public or shared yard-kiosk browsers.
• 🔒 Terminate Sessions on Yard Tablets: Always click Log Out after printing gate passes or checking booking statuses on shared driver tablets to prevent unauthorized cargo tracking or appointment tampering.
