Reported daily positions / last fix per vessel
Propulsion & Consumption
Shaft Speed — RPM zones @115
Service band 87–100 rpm (green). 105+ overspeed (red).
Apparent Slip — % fouling proxy
<10 green · 10–15 yellow · 15–20 orange · 20+ red. Each vessel's fixed propeller pitch; bold line = 7-day median.
Shaft Power — kW
Avg delivered shaft power. Spikes >12 MW flagged as sensor anomalies.
Fuel Oil Consumption — MT/day ME / Aux / Boiler
Aux = Genset. Stacked daily totals.
Hull/Prop Performance — kg/nm trend = fouling
Rising propulsion kg/nm at steady speed indicates hull/propeller fouling.
Speed ↔ Power curve Admiralty
SOG vs shaft power scatter — added-resistance / loading signature.
Emissions & Efficiency
SFOC — g/kWh
Specific fuel oil consumption (corrected where available).
Daily Distance & Speed
SOG distance (bars) and average speed (line).
Cluster Explorer
Custom Scatter pick any two axes
Plot any parameter against another to read loading / fouling / weather signatures. Respects date range, fleet selection and steaming filter; abnormal values excluded.
Voyage Planner
Optimum RPM · Speed · Fuel model from vessel data
Historical model estimate, not an operational engine setting. Subject to weather, loading, ETA and machinery limits.
Annual History All available years / steaming records
Year-over-Year annual vessel averages
Annual mean per vessel — fuel, slip, RPM and kW trends reveal hull condition, operating profile and machinery load changes.
Operating Profile speed histogram
Share of sea days in each 0.5 kn band — reveals slow-steaming behaviour and charter speed compliance.
Annual Avg RPM all fleet
OD, OF and OX are shown together; values are annual sea-passage averages.
Annual Avg kW all fleet
Shaft power annual average per vessel. Useful for load profile and drydock/performance comparison.
Findings
Latest source CII indicators
Legacy source values, not a verified annual CII rating.
Anomaly Register facts only
Auto-flagged from selected period. Operational: RPM>105, Slip>15%. Data/sensor: values outside physical bounds (hidden from charts).
