Over the past few months, we’ve rolled out a set of targeted enhancements to the Voyage calculator, designed to help teams plan, compare, and optimize voyage scenarios with greater precision and flexibility.
This release focuses on improving two core aspects of voyage planning: vessel coverage and port time accuracy. Together, these updates make it easier to model real-world chartering conditions, compare alternatives efficiently, and build confidence in voyage economics.
The key enhancements include:
Expanded vessel coverage with the addition of Baltic vessel models
Days in port calculation option for more accurate, calendar-based port time estimates
These improvements are available directly in the Voyage calculator and are designed to support more realistic planning and better decision-making across chartering and operations workflows.
1. Baltic Vessel models now available in Voyage calculator
We’ve expanded the vessel database by adding Baltic vessel models, giving users broader coverage when planning and comparing voyages.
What’s new
Baltic vessel models are now available directly in the vessel selection step
Users can search, filter, and compare routes using Baltic vessels
Results automatically reflect vessel-specific characteristics and performance
Why it matters
With Baltic vessel models available:
Users gain access to a broader and more representative vessel universe
Voyage comparisons become more accurate for specific chartering strategies
Route planning better reflects real-world fleet availability
2. Days in Port: Calendar-based port time calculations
The new days in port tool helps users calculate the calendar days required at a port, factoring in operational constraints and port working hours.
How it works
Dry Bulk
Days in port = (load ÷ load or discharge rate × port terms) + (turn time + extra time) ÷ 24
Liquids, LNG, LPG
Days in port = (load ÷ load or discharge rate × port terms + turn time + extra time) ÷ 24
Key Inputs Explained
Cargo Quantity
Refers to the amount of cargo loaded or discharged at the selected port
When a vessel is selected, the default quantity is set to the maximum load of the vessel
Rate
Default load and discharge rates are available for Dry and Liquids
Rates can be adjusted to reflect contractual or operational assumptions
Terms
Port terms convert working time into calendar days.
Total weekly hours: 168
Working hours = 168 − excluded hours
Port term factor = 168 ÷ working hours
This factor is applied to reflect non-working hours at the port.
Turn Time
Time required for berthing, port services, and departure preparation
Default values:
Dry: 12 hours
Liquids: 9 hours
Extra Time
Any additional waiting or idle time (e.g. congestion, operational delays)
Why it matters
The Days in Port tool provides:
More realistic port stay estimates
Better alignment with calendar-based voyage planning
Improved cost and schedule accuracy across voyage scenarios
