The vessel page is where compliance teams spend most of their time. It shows everything one vessel did in one year, across all five regulations.

​

What’s on the page

​

Summary cards

Four cards across the top: Voyages (count + total distance), Sea Days (+ port days), Total CO₂, Total Fuel. Each card is one number plus a sub-figure for context.

​

CII performance

A radial gauge plots Attained CII against the required line, with A/B/C/D/E zones drawn in the background. Next to it, a comparison box shows two CII values:

• Database CII — what’s reported in the consumption logs
• Corrected CII — with reefer container CO₂ stripped out per MEPC.355(78)

A link opens the MEPC.355(78) PDF in an in-app slide-out panel for reference.

​

EEOI

Two EEOI numbers, calculated automatically based on ship type:

• EEOI by TEU — gCO₂ / TEU-NM (for container ships)
• EEOI by Weight — gCO₂ / tonne-NM (for bulkers and general cargo)

Plus the underlying transport work, total CO₂, total distance, and average cargo per voyage.

​

Fuel breakdown

Tonnes by fuel type, displayed hierarchically:

• HFO (Total) = VLSFO + HFO LLS
• MDO / MGO
• LNG, Methanol, Biofuel blends, etc.

​

CII rolling chart

Daily Attained CII plotted over a multi-year window (2023 → current+1 year by default), with the year’s Required CII as a stepped baseline. Rating bands are drawn as background colours. A brush at the bottom lets you zoom into any date range.

​

Voyages table — expandable

One row per voyage with route, dates, total CO₂, distance, average CII, ETS classification, and ETS cost. Click any row to expand into a sub-table of legs:

• Leg # and route (port → port)
• Sea CO₂, sea-covered (with coverage %), EU port CO₂, total covered
• ETS coverage factor applied per leg

This is the most detailed view of how the EU ETS bill is built up for each vessel.

​

What you can do here

• See exactly which voyage and which leg generated each tonne of covered CO₂
• Compare attained CII trends against the required threshold over time
• Verify that reefer correction has been applied correctly
• Pick a year and see the year-end picture, or use YTD for live monitoring
• Use the breadcrumb to jump back to the fleet view
