Final answer:
A container ship is one of the vessels that does not have to comply with the rules regarding traffic separation schemes. They can transfer ballast water internally to maintain stability during cargo operations, avoiding the need for ballast water exchange.
Step-by-step explanation:
One of the vessels that does not have to comply with the rules regarding traffic separation schemes is a container ship. Container ships have the ability to transfer ballast water internally among tanks to maintain stability during cargo operations, which allows them to avoid conducting ballast water exchange in many circumstances. This practice has become more prevalent since ballast water management regulations were mandated in 2004. Another behavioral change adopted by container ships is to entrain ballast water from open ocean sources rather than coastal sources, eliminating the need for exchange.
