 ESPVLC - Valencia Port (Spain)- Draft & Bunker Surveys - Independent Marine & Cargo  Surveyors



The draft survey (UK)/ draught survey  (USA) is the recognized international method of determining a quantum of cargo loaded or discharged by measuring the change of displacement of a floating vessel.


Our Marine Surveyors are Naval Architects, experts in reading drafts, checking water density with calibrates hydrometers, sounding tanks to determinate the ballast  using the  ship's sounding table's.


We use specific software and mathematical computing algorithms to obtain the most accurate values of total the final displacement of your vessels and the cargo on board.





Bunker Survey, also know as Bunker Delivery Survey, Bunker Quantity Survey (BQS) or Bunker Stem Survey forms a critical part of preventing bunker delivery losses.


Our Bunker Surveyors are mainly employed to independently check and determine the barge delivered quantity and the vessel received quantity.


We send five representative bunker samples for laboratory testing after bunkering operation is completed according to ASTM/ISO 8217 and other specifications standards.


We only use approved  laboratories.
