Maintain a complete cargo operation log, including key timestamps, events, delays, and abnormalities throughout the operation.
Verify and endorse all relevant custody transfer documents, including but not limited to Delivery Report; Bill of Lading (B/L); Certificate of Origin; and Quality and Quantity Certificates

Verify all custody transfer metering system seals and FPSO cargo tank seals are intact prior to and after loading.
Witness sealing and breaking of seals at all agreed custody transfer points, including locations outside the metering system.
Witness unsealing of export hoses prior to loading and resealing upon completion.
Witness extraction of representative crude oil samples from FPSO cargo tanks before and after loading.
Witness installation and readiness of clean sampling systems and verify auto-samplers are properly flushed prior to lifting.
Witness laboratory analysis of samples (e.g., density, BS&W) and certify test results.
Verify temperature measurements (multi-point where applicable) and ensure correct application of VCF/CTL/CTPL calculations.

Witness verification of all preset key codes in metering system microcomputers before and after each batch operation.
Witness and record mechanical meter readings at the metering panel before and after each loading operation.
Witness reproduction of previous batch reports prior to batch start and verify recorded figures immediately report discrepancies to THE COMPANY Production Superintendent and PETRONAS representative.

Perform and document full quantity reconciliation between: FPSO tank measurements; Metered quantities; and Export tanker figures
Apply agreed tolerance limits and issue a Loss/Gain or Reconciliation Report.
Investigate and report discrepancies, including identification of probable causes (e.g., line fill, temperature variance, measurement error).
Account for line displacement volumes and include in reconciliation calculations

Witness and verify FPSO inventory stocktakes (monthly, quarterly, semi-annually, annually, and PSC anniversary).
Witness manual tank measurements (dip/ullage, temperature, water cut) and cross-check with automatic tank gauging systems where available.
Verify all tanks, including cargo, slop, and off-spec tanks, and confirm tank status.
Independently calculate volumes (GOV, GSV, NSV) using approved tables.
Perform full inventory reconciliation (report vs physical)
Quantify and report stock gain/loss and provide analysis of variances and trends.

Assist in expediting lifting and shipping documentation upon request
Communicate final certified figures (B/L quantity, API gravity, density, VCF, BS&W) to the export tanker surveyor.
Ensure all reports are accurate, complete, and submitted in a timely manner.
Maintain full audit trail of all measurements, calculations, and certifications.
Immediately report any operational irregularities, safety concerns, or discrepancies.

Prepare and endorse Shuttle Tanker Ullage Report based on pre- and post-loading measurements.
Certify quantity of crude oil received onboard the export tanker.
Witness and, where required, perform joint measurement surveys with vessel representatives.
Verify vessel conditions including ROB/OBQ (On Board Quantity) and vessel tank status prior to loading.
Consider Vessel Experience Factor (VEF) where applicable in reconciliation.
Conduct sampling of vessel slop tanks prior to loading (for water and hydrocarbons, if present), and ensure safe transfer of samples to FPSO HELANG for handover to the Terminal Shift Supervisor. To prepare and endorse Shuttle Tanker Ullage Report (from Shuttle Tanker's tank dip before loading and immediately after loading) in accordance with the procedures by PETRONAS and THE COMPANY.
