Abstract: A lifting system includes elevator towers constructed on a deck of a floating vessel, tracks constructed above the deck of the floating vessel, a traveling cradle beam, and one or more cranes supported by the traveling cradle beam. The traveling cradle beam can be in a first configuration in which the traveling cradle beam is coupled to the elevator towers and can move along the elevator towers past the tracks, and in a second configuration in which the traveling cradle beam is decoupled from the elevator towers and can skid over the tracks. The lifting system can be constructed in stages, and the portion of the lifting system constructed in the initial stages can be used to continue constructing the lifting system in the remaining stages. The lifting system can be used for transporting equipment on the floating vessel.

Abstract: A lashing system is usable on cargo ships that are transporting shipping containers, optionally as a supplement to standard lashing bridges provided on cargo ships. The lashing system includes a support that can interface with the pre-existing interlocking system provided on the shipping containers. The support can be lifted and placed on a stack of shipping containers using the same cranes used for loading and unloading shipping containers. The lashing system includes lashings that are attached to the support and are releasably connectable to another shipping container or to a structure of the cargo ship. The tension in the lashings is preferably monitored during the trips of the cargo ships.

Abstract: A repair axial bearing system includes an arcuate rail coupled to a support, one or more bolts protruding upward from a raised portion coupled to a supported member, and a lever plate including at least one low friction bearing pad mounted in the lever plate. A first new bearing surface is formed on the arcuate rail. A second new bearing surface is formed on the at least one low friction bearing pad. The one or more bolts are tensioned with bolt tensioners to press the lever plate against the raised portion. The axial bearing system can include a hydraulic cylinder to slide the second bearing surface over the first bearing surface. The repair axial bearing system can be used to supplant a damaged axial bearing positioned between an FPSO and a turret.
