A hold survey is an inspection of a ship's cargo holds to ensure they are clean, dry, and fit for the intended cargo. This survey helps prevent contamination and damage to the cargo.

Cargo lashing involves securing cargo on a vessel to prevent movement during transit. This process ensures that the cargo remains stable and safe, minimizing the risk of damage or loss. 

The CSS Code, or Code of Safe Practice for Cargo Stowage and Securing, is an international guideline developed by the International Maritime Organization (IMO) to ensure safe stowage and securing of cargo on ships. It provides best practices and recommendations for cargo handling.
