Section 246: Power to board and inspect vessels and marine installations
650.The powers in this section enable enforcement officers to board and inspect any vessels and marine installations (subject to the need for a warrant pursuant to section 249 if the vessel or installation is a dwelling) to carry out their functions. Enforcement officers may require the vessel or marine installation to stop or do anything else that would assist them in boarding or disembarking and in carrying out their enforcement duties. The power extends to things which may be under the control of someone on the vessel or installation, such as a vessel under tow. Marine installations that may move under their own power include jack-up rigs and work platforms. The powers also allow officers to require assistance from someone present who has some control over the situation.
