Every person before becoming a pipeline operator or a vessel operator shall apply to the board for a license on forms prescribed by the board. A pipeline operator license or a vessel operator license shall be issued only to a person who is a pipeline operator or a vessel operator as defined in Sections 7331 and 7344. It is unlawful for a person to act as a pipeline operator or a vessel operator without first securing a license.
