Escort Tugboat definition
Escort Tugboat means a tugboat with a primary vocation involving intercepting and escorting ATBs, or any ocean-going vessel entering or departing Regulated California Waters with the purpose of providing maneuvering or stopping assistance in case of loss of propulsion or steering power while in route to or departing from docks and terminals. Escort tugs will typically work with ship-assist harbor tugs to dock or undock their escorted ATBs or ocean-going vessels. Escort tugs may also stay with ATBs or ocean- going tanker vessels while they are offloading or loading petrochemical products for fire suppression assistance or emergency undocking.
