    Abstract: A retaining apparatus includes a barrier having an interior surface defining an aperture extending from a first end of the barrier to a second end of the barrier. The retaining apparatus has a first distance between opposing sides of the interior surface near the first end of the barrier, a second distance between the opposing sides of the interior surface at a position between the first and second ends of the barrier, and a third distance between the opposing sides of the interior surface at the second end of the barrier. The second distance is smaller than the first and third distances. The interior surface is configured to partially surround and support a work line, restricting movement of the work line in a transverse direction, allowing movement of the work line in a longitudinal direction, and allowing bending of the work line about an axis in the transverse direction.

    Abstract: A rooftop support system including at least one support block. The support block includes a base configured to rest on the rooftop, and the base has a first base section and a second base section separated by a U-shaped recess that defines a first gripping feature. The support block includes first and second sidewalls unitary with the base and extending along a length of the support block, and the first and second sidewalls each define a second gripping feature. The support block also includes third and fourth sidewalls unitary with the base and extending along a width of the support block, and the third and fourth sidewalls each define a third gripping feature. An upper surface of the support block defines an elongate channel, and a pair of apertures are formed in the elongate channel with a coupling feature embedded therein.

    Abstract: A pipeline including an accessory such as a flowline end termination or an in-line tee is lowered to the seabed and a mudmat foundation is subsequently lowered toward the seabed for subsea docking with the accessory to provide a permanent foundation support for the accessory. Once docked and with a mudmat of the foundation landed on the seabed, weight loads of the accessory structure and the attached pipe are transferred to the mudmat to provide a permanent foundation for the accessory structure. Before and during installation of the mudmat foundation, the pipe may be allowed to become embedded in the seabed. Temporary interim support such as buoyancy may be provided to the accessory to limit embedment into the seabed.

    Abstract: A pipe mat for use with a tubing tray for receiving, organizing and storing drill pipe tripped out of a drill string on a drilling rig has a plurality of substantially parallel and spaced-apart support rails to form a plurality of drain channels disposed between adjacent pair of support rails. A plurality of substantially parallel and spaced-apart nub rails is disposed on the plurality of support rails. The nub rails are substantially orthogonal to the support rails, thereby forming a lattice structure having openings disposed between the nub rails that are in communication with the drain channels. A plurality of spaced-apart pipe nubs extend upwardly from the nub rails, which hold a drill pipe in place when an end of the drill pipe is placed onto one of the pipe nubs. A method for collecting fluids draining from drill pipe uses the pipe mat with the tubing tray.

    Abstract: A pipeline termination arrangement to be mounted to a pipeline end section to support a pipeline hub of the pipeline end section during and after a subsea connection of the pipeline hub to a spool piece hub fixed to a spool piece termination structure is provided. The pipeline termination arrangement includes a landing structure for supporting the spool piece termination structure; a connection porch fixed to the landing structure; and a support structure which is fixed to the pipeline end section and provided with a guide frame. The guide frame slidably supports the landing structure so as to allow the landing structure and the connection porch to slide along the guide frame from a first position, in which the connection porch is located in front of and at a distance from the pipeline hub, to a second position, in which the connection porch is in contact with the pipeline hub.
