Container Ship Accident

Maneuvers in coastal waters and ports managed in the wheel house may be dangerous, as evidenced by a container ship hitting the San Francisco – Oakland Bay Bridge on November 7, 2007.
It has been estimated that container ships lose over 10,000 containers at sea each year. Most go overboard on the open sea during storms but there are some examples of whole ships being lost with their cargo. When containers are dropped, they immediately become an environmental threat—termed "marine debris".
Modern loading instruments (like MACS3 with BELCO, SEALASH and DAGO modules) assist to reduce the risks, caused by incorrect stowage of container cargo.
