Abstract: A method is described for controlled bending of a pipeline during the laying thereof in the sea, utilizing bend controlling/stopping means which are mounted on the pipeline as a sleeve and interact with the pipeline. To achieve cold bending under controlled conditions, the pipeline is weight loaded internally at the selected bending zone. The weight loading may be achieved by means of a flexible string of weight elements and/or by introducing into the pipe a suitable heavy, readily flowable weight mass, for example, drilling fluid.

Abstract: This invention provides a method for installing a self-floating deck structure with at least one recessed cavity on the bottom of the self-floating deck structure onto a buoyant substructure. The self-floating deck structure is aligned over a submerged buoyant substructure and the top of the buoyant substructure is inserted into a recessed cavity in the self-floating deck structure until the buoyant substructure mates with the self-floating deck structure at a point above the water surface. The self-floating deck and the buoyant substructure are connected by welding or one or more mechanical device.

Abstract: A security device. The device has a wedge to contact a door to prevent opening the door. An anchor is attached adjacent the door. A slot in the anchor is of predetermined length and width. A catch on the wedge has a limb extending from the wedge with a hook on the limb, remote from the wedge. The hook has a length and width less than the length and width of the slot in the anchor. To prevent opening of the door, the hook is engaged in the slot. Release of the wedge to enable opening of the door is achieved by moving the wedge so the hook portion lies along the slot and can be removed through the slot.

Abstract: Controlled bending of a pipeline laying on the sea floor is achieved by attaching a bending sleeve assembly to a selected bending zone of the pipeline for limiting the controlled bending of the pipeline to a predetermined resulting bending configuration. External force is then applied on the bending sleeve assembly, bending the pipeline to the predetermined resulting bending configuration in cooperation with the bending sleeve assembly and the sea floor. External force can be exerted from one or more weights placed on top of the bending sleeve assembly. External force can be exerted from a winch attached to a wire, the wire passing through a pulley attached to a fixed structure, and the wire attached to the bending sleeve assembly. External force can be exerted through the bending sleeve assembly's contact reaction with an immobile object.

Abstract: A bending restrictor assembly has a pipeline section, a first overlying pipe section having a wall overlying a portion of the pipeline section at one end thereof, a second overlying pipe section having a wall overlying another portion of the pipeline section at an opposite end thereof, and a plurality of cylindrical members overlying the pipeline section between the first and second overlying pipe sections. The first and second overlying pipe sections extend outwardly beyond the respective ends of the pipeline section. The bending restrictor assembly achieves a permanent bend and restricts ovality of a subsea pipe.

Abstract: A bending restrictor assembly for use with a pipeline section has a sleeve affixed to the pipeline section, an outer collar slidably positioned relative to and over the sleeve, and an inner collar slidably positioned relative to an interior of the outer collar. The inner collar in spaced longitudinal relation to an end of the sleeve. The inner and outer collars are slidable relative to a bending of the pipeline section. A series of holes and keyways are formed in the inner and outer collars. Pins are inserted into corresponding holes and keyways so as to correspond to a limit of the bending radius of the pipeline section.
