Speak With Our Surveyors

Vessels are complex assets with hidden defects that visual inspection alone cannot detect. Our qualified surveyors bring technical expertise, industry knowledge, and independent objectivity. We identify problems before they become your problems, potentially saving you tens or hundreds of thousands in avoided repairs, renegotiated purchase prices, or prevented operational failures.

Our detailed reports provide authoritative documentation for lenders, insurers, and classification societies, facilitating smooth transactions and establishing proper condition records from the start of your ownership or charter period.

Cargoes, commodities, and special objects move around the world and often involve the transfer of ownership, risk, and responsibility. The cargo surveyor can establish the condition, quantity, and quality at these moments of change and prevent damage or ascertain the cause and extent of any such damage.

Contact us today to discuss your survey requirements and ensure your assets are properly protected and documented.

Testimonials

Thank you Sir for the survey and more so for the time during the actual survey to educate me and expand my education and understanding of many aspects of boat construction. I appreciate very much the report.

Herbosch-Kiere NV hereby strongly supports the nomination of I.N.S. as an additional surveyor for tow surveys under the fleet policy of Herbosch-Kiere. Herbosch-Kiere regularly makes use of the services of I.N.S. and is very satisfied with their services. I.N.S. also has excellent references. In addition, the services of I.N.S. are geographically very well located, which benefits both the speed and the cost of their services.

Thank you, INS, for the great internship I was able to do with you. It was very interesting, especially because, alongside office and administrative work, I was given the opportunity to actually go on board seagoing vessels in the port and visit companies where you perform inspections and expertise. Wow!
