Marine Chock is a device used on ships to guide mooring lines and ropes, ensuring they are securely fastened and do not slip or move unexpectedly. They are critical for the safe and efficient mooring of vessels. Marine chocks are typically made of high-strength materials like cast steel to withstand the harsh marine environment and the heavy loads they encounter.Marine chocks must comply with various international standards and regulations to ensure safety and reliability. Organizations such as the International Maritime Organization (IMO) and classification societies like Lloyd's Register or the American Bureau of Shipping (ABS) provide guidelines for their design, placement, and maintenance.
