An apparatus and method for erecting a temporary emergency walkway for personnel between an offshore oil platform and a marine vessel. The disclosed apparatus includes a first walkway attached to the main boom of a crane mounted on the vessel and a second walkway attached to an extendable articulating auxiliary boom. The auxiliary boom, which is normally stored on the deck of the vessel, preferably includes an articulating section having a pair of pivotably connected subsections and an adjoining section which telescopically engages the articulating section. A rapid evacuation of personnel from the platform can be accomplished even in heavy seas by maneuvering the vessel into a position near the endangered platform, attaching the auxiliary boom to the main boom and by appropriate movements of the crane and auxiliary boom placing the end of the auxiliary boom on the platform. After the auxiliary boom has been secured to the deck of the oil platform, personnel can use the walkway so erected to move to a position of safety on the vessel, the emergency crews can move from the service vessel to the platform. The booms also may provide air, hydraulic, and electrical power from the vessel to the platform.
An oil fence arrangement for effectively preventing oil spills from spreading or diffusing over the surface of the sea. The arrangement is of a double wall construction and can fold into a small space.
