What are Bunker Surveys? Why Do vessels require Bunker Surveys?
Bunker Surveys certify the quantities of oil products onboard vessels/ships and/or barges before and after the bunkering according procedures of API MPMS chapter 17.1, with Bunker survey of ICSurveys, our clients can expect unbiased reports and confidentiality.
Bunker Surveys are carried out for DELIVERY and RE-DELIVERY of vessel / ship purposes and also for Loss Control in supervision of loading/discharging of petroleum products by tankers or barges.
In addition, survey of Petroleum products of ICSurveys to certify quality, quantities of oils/chemical/gas carried on the Motor Tanker of vessel’s tanks during pumping from shore’s tanks to vessel’s tanks and pumping out from vessel’s tanks to shore’s tanks. The composite samples taken by surveyors of ICSurveys.
This procedure is accredited by our ISO 17020 certification.
Below is a brief description of duties performed by our surveyors during every assignment.
- Physical checking of ship’s draft markings and clinometers to ascertain correct trim and list for opening calculation.
- Identify to Chief Engineer on boarding vessel, and request him to sign Pre-survey Acknowledgement.
- Confirm type, grade and quantity ordered with Chief Engineer.
- Request for Chief Engineer bunker plan and confirm nominated bunkering tanks.
- Identify all bunker fuel storage tanks location, sounding pipe position and reference height by inspecting tank calibration table and record it in Ship’s Measurement Report.
- Thorough gauging and temperature checking of all ship’s fuel tanks including settling, service, overflow and drain tank together with Chief Engineer or representative as witness. Record all findings in Gauging Ticket.
- Calculate pre-delivery volume in all tanks by applying trim and list correction and record it in opening readings of Ship’s Measurement Report.
- Physical checking of bunker tanker’s draft markings and clinometers to ascertain correct trim and list.
- Request bunker requisition form to confirm grade and bunker quantity ordered, rated bunker tanker pumping capacity, viscosity, density @ 15`C, flash point & water content of bunker to be supplied.
- Identify all cargo tanks location, sounding pipe position and reference height by inspecting tank calibration table and record it in Bunker Tanker’s Measurement Report.
- Complete and thorough inspection on all bunker tanker’s tanks inclusive of all non-cargo spaces and line system witness by Ship’s Chief Engineer or representative and the cargo officer.
- Repeated gauging taken to prevent illegal transfer of oil between tanks during measurement.
- Proper calculation of bunker quantities based on prevailing ASTM IP Petroleum Measurement Tables.
- Measurement of oil temperature for volumetric correction.
- Correction of bunker tanker’s trim & list for volumetric correction.
- Checking presence of water before bunker delivery.
- Record bunker tanker’s pre-delivery cargo tank quantity in the opening readings of Bunker Tanker’s Measurement Report
- When bunker has complete, surveyor will check bunker tanker’s draft markings and clinometers to ascertain correct trim and list.
- Complete and thorough gauging of bunker tanker’s cargo tanks, non cargo tanks and line system witness by Ship’s Chief Engineer or representative and the cargo officer.
- Record all findings in the closing readings in Bunker Tanker’s Measurement Report
- Gauging of ship’s nominated tanks and recording it in closing readings of Ship’s Measurement Report.
- Compute quantity delivered based on the supplier’s provided density.
- Inform the Chief Engineer if quantity is different from the cargo officer calculated quantity or Bunker Delivery Note.
During Bunkering Operation
- Continuous surveillance during and throughout the pumping operation.
- Record all timing for bunker operation in the Survey Time Log.
- Witnessing & collection of representative bunker samples ensuring that they are properly labeled sealed and distributed with acknowledgement by all parties.
- Retention of bunker sample and dispatch of bunker sample to appointed independent laboratory for testing when required.
- Record all information in Sample Witnessing And Receipt.
- Ensuring proper reports, documentation of all measurement, calculation method, sampling method and distribution are submitted in good order.
- Ensuring compliance with Panamanian law in this respect and reporting on any non-compliance by recording it in the Statement Of Fact document.
