Abstract: Combustor maintenance assemblies, tools and methods for manipulating cross-fire tubes in combustor assemblies are provided. A tool includes a base and an arm pivotally connected to the base. The arm includes an effort portion and a load portion, the load portion extendable into a passage defined by the compressor discharge casing. The tool further includes a contact member extending from the load portion to contact the cross-fire tube. The contact member includes a head end for contacting a second end of the cross-fire tube, and a joint disposed between the head end and the load portion, the joint allowing movement of the head end relative to the load portion. The arm is movable such that the contact member contacts the cross-fire tube and applies a force to the cross-fire tube generally along a longitudinal axis of the cross-fire tube.

Abstract: A device for recovery of physical objects includes a chain having two ends and a retriever attached to one of the ends. The retriever is configured to locate the object to be recovered and to grasp and retrieve that object once located. The retriever includes transducers that detect acoustic frequencies propagating in a fluid medium. Independent transponders, which can be deployed from the retriever; are provided for deployment in an area to be searched. Each transponder emits a predetermined acoustic frequency that is detectable by the transducers. The transducers signal movement of the recovery device for retrieval of the object.

Abstract: A light weight lifting tool (10) for lowering and retrieving subsea equipment to and from the sea bed is disclosed. The equipment includes an upper coupling part in the form of a connector spool piece (15) having at least one circumferential ring groove (16) for use in making engagement with the lifting tool (10). The lifting tool (10) includes a housing (1) designed to enclose and receive the connector spool piece (15). The lifting tool (10) further includes a number of latch segments (8) having at least one radially inwards directed projection (8?) designed for engagement with the at least one ring groove (16), and an activating device (6) arranged to bring the latch segments (8) in and out of engagement with the at least one ring groove (16) by operation of the activating device (6).

Abstract: A floating object is attached to a shipboard hoisting crane through its attachment device under high seawave conditions, by maintaining alignment of the crane attachment device under maneuvering thrust control with a location on the floating object during lowering of the attachment device onto the floating object. Such maneuvering thrust control is established by thrust jets emitted from the attachment device under control of optical scanning detection cells mounted on the attachment device for reception of a reception location indicating beam emitted from the floating object.
