Cargo Inspection

Expert Analysis of Every Type of Cargo and Container





We are familiar with all types of foodstuffs including fruits and vegetables as well as rices, coffees, teas and spices. 

  • Quarterdeck Marine Surveyors always test with silver nitrate for salt water invasion as well as improper temperature settings. 

  • Bananas at an acceptable temperature. Intimate knowledge of the produce is the key to a proper survey.

  • Bananas in original cartons, packaging is of the utmost importance for produce of this delicate nature.

  • Quarterdeck Marine Surveyors use their years of experience to evaluate any degradation of coffees, teas and spices.





Our expertise with refrigerated containers, (REFERS) is very often called upon to analyze the cause of fruit, seafood, and vegetable degradation.

Machinery and Various Bulk Shipments




Quarterdeck Marine Surveyors are often called upon to investigate damage to cargo from improper shipping conditions.  Quarterdeck Marine Surveyors prefer to always be at the receiving site prior to unloading any cargos that are reported to have possible problems.  Our analysis often reveals improper stabilization of heavy objects in containers for shipping. 


Seals are checked against manifests to insure accuracy of shipping documents.
