Abstract: An apparatus, system and method of manufacturing a marine riser constructed of an aluminum alloy having a high strength-to-weight ratio is provided. The inventive riser apparatus comprises a plurality of riser sections coupled serially end-to-end, wherein each of the riser sections comprises a pipe having a first end and a second end, a first flanged coupling welded to the first end of the pipe, and a second flanged coupling welded to the second end of the pipe, wherein the pipe is constructed of an aluminum alloy having a strength-to-weight ratio greater than that of steel. The riser apparatus may optionally include one or more auxiliary lines providing hydraulic communication with a blowout preventer.

Abstract: A moveable track cover is provided for use with a mechanism configured to move along a track. One example of such a mechanism is a pipe racking system used on off-shore oil and gas platforms. One end of the moveable track cover is connected to the pipe racking system mechanism which moves along the track. The other end of the track cover is spooled onto a drum. Rotation of the drum is controlled by a motor which exerts enough force to maintain the track cover in constant tension. When the pipe racking system mechanism moves towards the drum, the motor rotates the drum to roll the track cover onto the drum. When the pipe racking system mechanism moves away from the drum, it pulls the track cover off of the drum. By attaching a track cover to each side of the pipe racking system mechanism, the track along which the pipe racking system mechanism travels is kept covered at all times. The track cover may be constructed of a sheet of stainless steel strengthened by rib assemblies.

Abstract: A pressure accumulator apparatus is disclosed for use in offshore drilling and production which comprises a pressure vessel (30) having a first compartment (34) and a second compartment (38), a partition (32) between the first compartment and the second compartment, a means for admitting fluid at ambient pressure into a portion (44) of the first compartment, a means for controlling an amount of hydraulic fluid ejected from a portion (46) of the second compartment, a first piston member (48) circumscribed by an interior wall of the first compartment, said first piston member being capable of sliding within the first compartment, a second piston member (50) circumscribed by an interior wall of the second compartment, said second piston member being capable of sliding within the second compartment, and a means (52) for connecting the first piston member and the second piston member.
