Marlo – Operations

The Operations module is where voyage execution happens. Marlo empowers operations teams to manage port activities, track vessel movements, handle laytime/demurrage, and generate necessary commercial documents—all within a streamlined workflow designed for real-time decision-making and accuracy.

Concepts in the module

• Voyage Lifecycle – From scheduling to closure

• Port Calls – Load, discharge, bunkering events

• Laytime & Demurrage – Automated calculations and adjustments

• Voyage Invoices – Freight, Hire, Demurrage, Commission Bills

• Voyage P&L – Cost vs. Estimate variance

• Voyage Statuses – Draft, Scheduled,/On‑Voyage/Completed/Closed

Workflows in the module

1. Create a New Voyage

2. Manage Port Calls & Activities

   • Enter demurrage/laytime data manually or via automation

3. Generate and Manage Invoices

   • Create freight or hire invoices directly from voyage data

   • Adjust invoice values for demurrage, commissions, bunker charges

   • Submit for approval or sync to Finance for posting

4. Monitor Voyage P&L & Variances

   • Compare actual costs and revenues against the original estimate
