BWTS (Ballast Water Treatment System) survey refers to the surveying of ships to ensure that their ballast water tanks meet IMO (International Maritime Organization) requirements.
Improving vessel safety: A proper BWTS survey can help improve the safety of vessel operations. If a ballast water tank is damaged or defective, it can affect the stability of the ship.
Avoiding costs and penalties: If a ship does not comply with the BWTS standard, it may incur high costs for rebuilding the ballast water system and penalties for violating environmental regulations.
