Built for Every Survey
Bunker Quantity Survey (BQS)
Bunker delivery quantities checked against BDN figures using ASTM-calculated volume and density.
On-Hire / Off-Hire
Fuel and condition checks at charter handover, fully documented for owners and charterers.

Smart Automations
Offline-First Operation
One online load syncs the survey; surveyors work fully offline onboard; auto-sync on reconnect.
ASTM Auto-Calculations
VCF, GSV, weight in vacuum/air computed instantly; zero manual formulas.
Density Auto-Calculation
Closing gauging density auto-derived from opening data and supplier spec.
Copy Opening → Closing
One click pre-fills closing fields; cuts data entry time by half.
Auto-Report Generation
BQS report, ROB certificate, On/Off-Hire Certificate, LOP/SOF generated instantly, formatted and numbered.
Photo-Integrated Reports
Photos auto-resized and embedded into reports, no manual editing.
Transparency & Turnaround
Live Survey Status
Yet to Assign → Assigned → On Going → To Review → Completed, visible in real time.
Four-Party Seal Verification
Vessel, Barge, Surveyor seal numbers logged independently, plus one optional joint party.
Bunkering Timelog
Hose connected, flow started, disputes raised, disconnected — all timestamped.
QA/QC Review Gate
Back-office review before finalisation; corrections sent digitally.
Survey-Based Messaging
All communication attached to the survey record.
MFM & Physical Measurement
Supports MFM, Physical Measurement, and dual mode, with ASTM Table 56 conversions.
Built-in Workflow Tools
Real-Time Vessel Status Updates
Team members can post instructions and status updates directly against a specific survey, keeping a running, timestamped log the whole team can see. Update recipients are also notified by email, so nothing gets missed even if they're not in the app.
On-Demand Hiring Certificates
Generate an On-Hire / Off-Hire certificate for any barge involved in a survey, choosing before-supply or after-supply state. Multiple consumption and supply events can be added and certified individually, so a vessel with several bunker deliveries or barge changes still gets a clean certificate per event.
Photo Evidence, Auto-Placed in Your Report
Surveyors can upload photos directly from their device during the survey and tag each one to the relevant report section — vessel header, MassFlow meter, sampling, and more. Tagged photos are automatically inserted into the correct section of the generated report, no manual formatting needed.
Access & Security
- Role-based access control (RBAC) with granular permissions
- Contractor access auto-revoked on survey completion
- Client data fully isolated by survey
- Remote force-logout via Device Control
- Full audit trail from assignment to completion
- Configurable pre-load vessel tanks
