    Abstract: A method of installing a subsea pipeline having a direct tie-in between a first section of the pipeline and a subsea structure, wherein, after installation, the first section is located at a tie-in position. The method comprises: laying at least a portion of the pipeline from a laying vessel, the at least a portion of the pipeline including the first section and a second section of the pipeline, such that the first section is beyond the tie-in position in the laying direction, and the first section and the tie-in position are beyond the second section in the laying direction; either before, during or after said laying, configuring the second section such that bending will be preferentially induced in the second section of the at least a portion of the pipeline when the first section is pushed or pulled back to the tie-in position; pushing or pulling the first section back to the tie-in position, wherein, responsive to said pushing or pulling, bending is preferentially induced in the second section.

    Abstract: A method of installing an electrically-heatable subsea flowline includes launching the flowline with at least one electric power cable attached in piggybacked relation. After landing the flowline with the piggybacked cable on the seabed, a free end portion of the, or each, cable having a length greater than the water depth is released from the flowline. This allows a free end of the, or each, cable to be recovered to the surface to be spliced to one or more power supply conductors. After lowering the, or each, cable and the, or each, connected conductor beneath the surface, the free end portion of at least one cable is reattached to the flowline on the seabed in piggybacked relation. To perform the method, a subsea flowline assembly includes subsea-releasable fastenings spaced along the cable and the flowline to attach at least an end portion of the cable releasably to the flowline.

    Abstract: A system and method for laying an underwater pipeline is provided. The present invention includes a plurality of pipe support rings connected together by tension cables. The tension cables are secured to a S or J laying ship by a winch. The plurality of pipe support rings form a pipe channel sized to guide the underwater pipeline. The present invention further includes a sea water pipe having a distal portion and a proximal end. The proximal end is fluidly connected with a pump on board the ship. The distal end includes a plurality of nozzles. The sea water pipe is disposed underneath the plurality of pipe support rings. The underwater pipeline is fed through the plurality of pipe support rings while the nozzles form a trench on a sea bed.

    Abstract: A method of installing a plurality of pin piles into a seabed including at least the steps of: (a) lowering a pin pile apparatus comprising a first pin pile and an attached clump weight towards the seabed; (b) allowing the first pin pile to self-penetrate the seabed based on self-weight of the pin pile apparatus and the momentum from step (a) until the clump weight reaches the sea bed; (c) disconnecting the clump weight from the first pin pile; and (d) recovering the clump weight for use with a second pin pile and repeating steps (a)-(c). In this way, the pin piles are easily installed from their descent to the seabed with the clump weight, which can then be removed and applied to the next pin pile in an easy and repeatable operation without requiring a suction apparatus or hammer or drill.

    Abstract: Pipeline segments can contain cables, such as communication cables (e.g., fiber optic cables) within insulation material surrounding the pipeline segments. Cables can be embedded within the insulation material, run through conduits embedded within the insulation material, placed in channels formed in the insulation material, or otherwise. Channels containing one or more cables can be filled with supplemental insulation material, thus securing the cables within the channels. Pipelines created as disclosed herein can enable data transfer between distant points without the need to lay fiber optic cable in addition to the pipeline. Further, fiber optic cable embedded thusly can be used to sense conditions in the pipeline, such as leaks, seismic activity, strain, and temperature information.

    Abstract: A method of transporting a rigid tie-in connection across a body of water for installation underwater is disclosed. The method includes the step of supporting the tie-in connection in the water by buoyancy acting on a frame that supports the tie-in connection until installation. The buoyancy-supported frame is lowered and the tie-in connection into a sub-surface transit configuration. The method further includes in the transit configuration, towing the buoyancy-supported frame and the tie-in connection behind a towing vessel toward an installation site. Also disclosed is a system for implementing the method. The system includes a towable frame arranged to support the tie-in connection until installation and an external buoyancy attached to the frame by an extensible suspension link arranged to suspend the frame from the buoyancy in water in use. The link is extensible to lower the frame from a raised surface-tow configuration into a lowered sub-surface transit configuration.
