Draft Survey

Draft Survey Services

By Bashan & Gilead Marine Services Pte Ltd (BGMS)

A Draft Survey is a fundamental method for determining the weight of cargo loaded onto or discharged from a vessel. At BGMS, we conduct accurate, independent draft surveys in accordance with internationally recognized standards (e.g., UN ECE, IMO, ISO), ensuring transparency, efficiency, and protection for all parties involved.


Purpose of a Draft Survey

A draft survey provides a reliable means of calculating cargo quantity by measuring the vessel’s displacement before and after loading or discharging. This method is especially vital when:

  • Weighbridges or shore scales are not available
     
  • Bulk cargoes such as coal, iron ore, grain, or fertilizers are being handled
     
  • Legal or contractual verification is required
     

Benefits of a Draft Survey

1. Cargo Quantity Verification

Draft surveys determine the weight of cargo through displacement measurements and corrections for variables such as water density, trim, and list. This ensures accurate recording of cargo loaded or discharged.

2. Prevention of Cargo Disputes

By confirming actual cargo volumes, a draft survey prevents issues of shortage, overage, or misreporting, thereby reducing the likelihood of financial losses, demurrage claims, or disputes between parties.

3. Regulatory Compliance

Draft surveys may be required by port authorities, customs officials, or cargo regulators—especially when handling hazardous materials or controlled commodities—to verify shipment quantities in line with safety and legal requirements.

4. Risk Management & Operational Efficiency

By identifying anomalies or inconsistencies during loading/discharging operations, the survey enhances cargo integrity monitoring, loss prevention, and time management.

5. Legal and Commercial Protection

In cases of disagreement or claims, the draft survey report serves as a legal document and independent record of cargo quantity, supporting arbitration, insurance claims, or litigation.
