Comprehensive Marine & Cargo Services in Liberia
We offer a full suite of services across Liberia to protect your assets and interests.
Draft Surveys
For bulk cargo shipments like iron ore, a draft survey is the most reliable method of weight determination. Our expert surveyors meticulously measure the vessel’s displacement before and after loading/discharging to accurately calculate the cargo quantity.
Cargo Discharge/Loading & Tally Surveys
We provide on-site supervision of cargo operations. Our tally clerks conduct a piece-by-piece count of breakbulk cargo like timber, rubber, and bagged goods, verifying quantities against shipping documents to prevent short-landing or over-landing claims.
Ship Condition Surveys
Before a vessel goes on or off-hire, a thorough condition survey is essential. We document the vessel’s structural integrity and equipment. This detailed report serves as crucial proof of the vessel’s condition, protecting both ship owners and charterers from claims for pre-existing damages.
Loss Prevention
Our proactive loss prevention services are designed to mitigate risks before they result in a claim. We assess and advise on all aspects of the supply chain, from packaging and container stuffing to cargo securing and handling procedures, helping you reduce insurance claims and protect your cargo.

Frequently Asked Questions
Why is an independent Draft Survey crucial for iron ore exports from Buchanan?
For high-value, high-volume commodities like iron ore, a draft survey is the most accurate and internationally accepted method to determine the cargo’s weight. It protects both buyer and seller by providing a reliable, independent weight certificate that forms the basis of the commercial invoice, preventing disputes over quantity.
What is the difference between a Draft Survey and a Tally Survey?
A Draft Survey determines the weight of bulk cargo (like iron ore) by measuring the vessel’s displacement. A Tally Survey is a physical piece-by-piece count of breakbulk cargo (like timber or bagged goods) to verify the quantity loaded or discharged against shipping documents.
Can you perform a Tally survey and a condition survey at the same time in Monrovia?
Yes. We frequently conduct combined surveys for vessels. Performing a Tally survey during cargo operations and a Condition survey for an on/off-hire during the same port call is an efficient and cost-effective way to protect your interests.
