DRAFT SURVEY A draft survey is a means of determining the weight of any materials being loaded into (or discharged from) a vessel. QSS’s experienced and highly qualified professionals can conduct a draft survey on your behalf and produce an independent draft survey report.


A bunker survey establishes the amount of bunker and lube oil onboard the vessel. These surveys are an important loss-prevention measure since documentation of bunker operations is required in the event of a dispute or claim.


A conditional survey is usually done in association with a bunker survey. A conditional survey is performed to inspect and record the condition of the loading gear, cargo holds and hatches of the vessel. We are provide you with documented independent proof of the actual condition of the vessel you are buying, chartering or using. Our report can be used to substantiate claims that may arise because of damage to the vessel or cargo.

Buyers or sellers can order an us to inspection of the hold prior to loading. This gives both parties the confidence that the cargo will not be contaminated by material already in the hold, or affected in any way by vessel deficiencies. Our inspectors photograph, document and report on any abnormalities they encounter. After completing the assessment, we provide an internationally recognized certificate of inspection.

Visually inspect hatch covers at departure and arrival for water tightness and proper operation Look for obvious damage, holes and leak points that may jeopardize the quality of the cargo Hose and Ultrasonic Leak Detection (ULD) tests for objective assessment and verification We’re used new USM – Ultra sonic machine with international standard certificate

5. On/Off-Hire survey 

Whether you are the owner or the charterer, it is critical to have sound, reputable documentation of the condition of a vessel at the beginning and conclusion of a charter agreement.

This information is crucial in the event of a dispute over the condition and maintenance of the vessel following a charter term.

At the end of the charter, he re-examines the vessel and documents any noteworthy changes. Detailed reports are then given to all parties involved in the charter. The report can be a key piece of independent evidence that can protect your interests in the case of a dispute over the maintenance state or condition of a vessel at the conclusion
