Abstract: A method of attaching a plurality of cables such as trace heating cables to an elongate pipeline comprises bringing together the pipeline and an elongate mat along a common longitudinal direction, wrapping the mat around at least a majority of the circumference of the pipeline, and fixing the wrapped mat to the pipeline. The mat comprises at least two longitudinally-extending cables that are supported by a pliant substrate so that when the mat is wrapped around the pipeline, the cables are positioned at respective angular positions about a longitudinal axis of the pipeline. The mat may be guided from a planar configuration on exiting a reel into a configuration that is curved about the longitudinal axis. Centraliser spacers and thermal insulation may be added around the pipeline and the wrapped mat before the assembly is inserted into an outer pipe.

Abstract: An electric heating system (16) for a subsea pipeline (10) comprises heating sections (16A, 16B) disposed in neighbouring longitudinal succession. A switchboard (26) is configured to supply power in a cycle alternating between the sections. Levels of heating power supplied to the sections are in mutually-opposed alternation throughout that cycle. During the cycle, a greater level of heating power is supplied to a first section (16A) than to a second section (16B) for a period of time. Conversely, a greater level of heating power is supplied to the second section (16B) than to the first section (16A) before and after that period. For example, the second section may be deactivated during that period and the first section may be deactivated outside that period. By applying heat in this intermittent or fluctuating manner, the overall power requirement of the system is greatly reduced. There is a corresponding reduction in the size, complexity and cost of power generation and transmission hardware.

Abstract: A subsea riser is installed by lowering at least one riser conduit to the seabed when piggybacked to an elongate support that comprises at least one flowline. The elongate support may be a pipeline bundle, which may be attached to one or more towheads in a towable bundle unit. The riser conduit may be in fluid communication with the flowline. At the seabed, a free end portion of the riser conduit is detached from the elongate support by releasing subsea-releasable fastenings. Then, with the elongate support and a root end of the riser remaining at the seabed, the detached free end portion of the riser conduit is lifted away from the elongate support to a riser support, such as a platform, an FPSO or a buoy.

Abstract: A subsea assistance system for supporting saturation diver operations comprises a UUV such as an observation ROV that can be flown to a subsea worksite, and various items of ancillary electrical equipment that are connected or subsea-connectable to the UUVor to a skid forming part of the UUV. Those items may comprise any of: a hand-portable subsea display that displays an image to a diver communicated from the UUV, which image may be generated or enhanced underwater and/or by surface support; a subsea camera that captures subsea image data for communication to the UUV and from the UUV to surface support; and a selection of electrical power tools for performing subsea tasks. Fast-acting protective devices protect divers when using high-voltage wet-mateable subsea connectors on the UUV.

Abstract: A top connector (12) for a tether (16) of a subsea buoy (10) comprises a support (46), a lever member (60) movable about a pivot axis, and a chain stop mechanism (64) mounted on the lever member (60) to be situated below the pivot axis in use. The lever member (60) is pivotably connected to the support (46) via a flex joint (58) arranged to bear a tensile load exerted by a top chain (22) of the tether (16) when engaged with the chain stop mechanism (64). The flex joint (58) improves bending fatigue life of the top chain (22). A frame (30) extends upwardly from the support (46) to carry a sheave (32) for the top chain (22). A pivotably connected lever member (62) extends downwardly from the support (46). The lever member (62) is pivotable relative to the support (46) and the frame (30), allowing a compact arrangement that avoids the frame (30), the top chain (22) or the sheave (32) clashing with the shell (14) of the buoy (10).
