Features

Track each fuel and lubricant grade your fleet uses with 23 built-in consumable types. The 9 fossil fuel grades cover the full range of marine propulsion and auxiliary fuels. They are MGO, MDO, IFO, MFO, HFO, LFO, LNG, and LPG butane and propane.

The 2 sustainable fuels, Ethanol and Methanol, support the move to alternative energy sources.

The 10 lubricant grades cover each mechanical system onboard. They are Engine Oil, Cylinder Oil, System Oil, Hydraulic Oil, Gear Oil, Air Compressor Oils, Refrigeration Oils, Gas Compressor Oils, Bearing and Circulating Oils, and Turbine Oils. Each type carries a predefined CO2 conversion factor (CF). That allows automatic emission calculation with no manual lookup or setup.

Record each consumable movement with 5 purpose-built transaction types. Operational logs capture daily consumption during normal vessel operations.

Loss logs document unexpected depletion: leaks, spills, or measurement discrepancies. Addition logs record bunkering, freshwater loading, and lubricant top-ups.

Offboard logs track transfers to shore facilities, barges, or other vessels. Waste logs record sludge discharge, bilge water processing, and garbage disposal.

Each transaction type captures quantity, date, remarks, and the responsible officer. This builds a complete, categorized ledger of each consumable movement.

Calculate CO2 emissions automatically from fuel consumption data using per-fuel-type conversion factors (CF). Each of the 23 fuel and lubricant types carries its own CF value. That allows precise emission calculation with no manual lookup tables or external spreadsheet formulas.

The same fuel factors drive the per-voyage emissions reporting in Navatom Voyage, for EU MRV, IMO DCS and CII.

Organize all consumables and waste streams into 10 structured categories that mirror real operations. The 5 consumable categories cover each input your vessels need. They are Residual and Distillate Fuels, Lubricants, Additives, Fresh Water, and Technical Water.

The 4 waste categories track each output that needs disposal or offloading. They are Sludge, Dirty Oil, Bilge, and Garbage.

Each category carries its own storage rules (single or multiple items per ship), rank-based access authorization, and unit of measurement defaults. Per-category setup means engine officers manage fuel and lubricant records while deck officers handle water and garbage. This reflects the real split of duties onboard.

Track consumption by the day, with automatic delta calculation between today's amount and the running total. Each consumable item keeps a current total quantity (ROB, Remaining on Board). It also keeps a daily amount. Engineers can monitor daily burn rates and spot anomalies at once.

The per-date record answers what was on board on any past day.

Measure consumables and waste in the unit that matches each category and use. The 5 supported units cover each measurement standard used across global maritime operations. They are Metric Tonnes (MT), Cubic Metres (M³), Litres, Kilograms (KG), and Gallons.

Units are assigned per item. Fuel quantities are tracked in MT, lubricant volumes use Litres and freshwater uses M³. Consistent units across the fleet remove conversion errors and allow accurate aggregation in analytics. They also make sure regulatory reports use the correct measurement basis.

Link consumable items directly to the Planned Maintenance System equipment hierarchy. Attach specific fuel types to main engines, generators, and boilers.

Connect lubricant grades to the machinery that consumes them. Cylinder oil goes to main engine cylinders, hydraulic oil to deck cranes, and gear oil to reduction gearboxes.

Equipment integration creates a two-way link, so engineers see which consumables belong to each piece of equipment.

Control who holds authority over consumable records with per-category rank authorization. Engine officers record fuels, lubricants, additives, sludge, dirty oil and bilge.

Deck officers record fresh water, technical water and garbage, and the office follows each entry from its own app.

Rank-based access reflects the real split of duties onboard. The Chief Engineer owns bunker management, while the Master oversees water and waste compliance. The system prevents unauthorized modifications and ensures accountability. It supports the ISM Code's call for clear assignment of duties in safety-critical operations.

Configure whether each consumption category allows a single item or multiple items per ship. Single-item categories (e.g., Fresh Water) keep one running total per vessel, simple and unambiguous.

Multiple-item categories (e.g., Lubricants) allow separate tracking of each grade: Cylinder Oil, System Oil, Hydraulic Oil. Each has independent quantities and transaction histories.

Storage rules are set at the category level and enforced fleet-wide. This keeps the data structure consistent across all vessels. When a category is set to single storage, the system prevents duplicate items.

When it is set to multiple storage, it allows unlimited items. Each item is clearly identified by type and equipment association.

Document each consumable record with threaded comments and multi-file attachments. Add remarks to explain unusual consumption events. Examples are a bunker quality issue, a tank measurement discrepancy, or a waste discharge operation.

Attach supporting files: bunker delivery notes, fuel quality certificates, waste disposal receipts, and tank sounding records.

Several files upload at once with progress shown. Each comment and file action (add, edit, remove) is recorded in the event log with full user attribution.

Structured transaction data and contextual documentation together create a complete record for regulatory compliance and operational review.

A chart shows each item's balance on a vessel through the year. It shows what was added, used, lost, delivered ashore and discharged as waste.

Manage the full lifecycle of consumable items with active and deprecated status tracking. A fuel type may be phased out, a lubricant grade replaced, or an additive no longer used. Mark the item as Deprecated rather than deleting it.

Deprecated items keep their full transaction history for audit purposes, while hidden from active views.

Restore lets you reactivate deprecated items when needed. A fuel type may return to service, or a lubricant grade may be re-sourced. The lifecycle model keeps views clean without losing historical data. It suits both daily use and long-term record-keeping.

Each action in Consumption & Waste is recorded with who and when. This covers items added and retired, each entry and its edits, linked equipment, comments and files.
