Operator
Operator means a person who is an owner, a demise charterer, or other contractor, who conducts the operation of, or who is responsible for the operation of, a vessel. A builder, repairer, scrapper, lessor, or seller who is responsible, or who agrees by contract to become responsible, for a vessel is an operator. A time or voyage charterer that does not assume responsibility for the operation of a vessel is not an operator for the purposes of this subpart.
