Abstract: A foldable walkway may include a platform having a first end and a second end longitudinally opposite the first end, a ladder pivotally coupled to the first end via a first pair of pivot joints, and a pair of supports pivotally coupled to the second end via a second pair of pivot joints. The ladder and the platform are configured to be manually pivoted about the respective first and second pairs of pivot joints. The ladder includes a first portion pivotally coupled to the first end of the platform via the first pair of pivot joints, a second portion movably coupled to the first portion to increase or decrease an extent of the ladder, and a spring having a first end coupled to the first portion and a second end coupled to the second portion.

Abstract: Apparatus, systems, and methods for supporting tubular members are provided. A support structure can include at least one body having a plurality of openings disposed therethrough. Each opening can have an inner surface that includes at least one circular portion and at least one elliptical portion.

Abstract: Apparatus and methods for supporting one or more elongated members are provided. A support member for supporting one or more elongated members can include a body; at least four support arms extending from the body, and at least one curved surface disposed between the support arms. Each curved surface can be concave relative to a centerline of the body. At least one curved surface can have a length that is at least twice as long as at least one other curved surface.

Abstract: The present invention is directed to a fairing system for the reduction of vortex-induced vibration and minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing system includes a plurality of cylindrical shells rotatably mounted about a cylindrical element immersed in a fluid medium. Each cylindrical shell has opposing edges defining a longitudinal gap configured to allow the shells to snap around the cylindrical element. The longitudinal gap has a circumference of about 120° relative to the circumference of each shell. Alternatively the longitudinal gap can have a circumference of about 60° relative to the circumference of each shell. The shells also include a fin positioned along the each opposing edge of the longitudinal gap, in which each fin extends outwardly from each shell. The fins are positioned on each shell so as to reduce vortex-induced vibration and minimize drag on the cylindrical element.

Abstract: An apparatus for permanently securing a grating sheet having parallel and transverse bars that form a pattern of openings to a structural member. The apparatus includes an elongated generally L-shaped connector having an upper plate section generally rectangular in shape for mounting on an upper surface of the grating sheet and a downwardly extending sidewall formed integrally with the plate section and adapted to extend along a longitudinal edge of the grating sheet. The L-shaped connector also can include a plurality of downwardly extending teeth formed integrally with the plate section and spaced apart from each other for insertion in between the grating bars. At least one generally right-angled brace is attached to the outer surface of the sidewall for permanently securing the L-shaped connector to the structural member.

Abstract: A mudmat assembly for supporting a portion of a subsea offshore platform on a soft, unconsolidated underwater surface is described. The mudmat assembly includes at least one fiberglass plank, a mudline framing plane that is attached to and provides support for the fiberglass plank, and integral framing beams attached to and providing support for the fiberglass plank. The fiberglass mudmat assembly of the present invention requires minimal cathodic protection, has a high flexural strength, and is lighter than conventional mudmats.
