A subsea pipe connection assembly has a first flange, a nut magazine positioned against a side of the first flange and having a plurality of nuts therein corresponding to the plurality of holes of the first flange, a second flange having a plurality of holes in alignment with the holes of the first flange, and a plurality of studs extending through holes of the first and second flanges such that the nuts in the nut magazine are affixed to the ends of the studs. A sleeve is affixed to and extending from the second flange. An ROV-delivered frame can be supported on the sleeve of the pipe such that a torquing tool connected to the frame can apply torque to a nut on the stud. The sleeve has a guide surface thereon so as to direct the torquing tool to nuts on the plurality of studs.

Subsea pipe connection assembly and method

A system for remediating hydrates has a heat storage box with an interior volume, a heater for heating fluid flowing into the hot fluid inlet of the heat storage box, a heat exchanger positioned in the interior volume of the heat storage box so as to be in heat exchange relationship with heated water from the interior volume of the heat storage box, and a line connected to a heated water outlet of the heat exchanger so as to be manipulated toward a location of the hydrates for the purpose of delivering the heated water toward the hydrates. The heat exchanger is piping extends in a serpentine pattern within an upper portion of the heat storage box. The line can be connected to a hot stab suitable for a manipulation by an ROV.

An anchor pile apparatus for placement in subsea soil has a tubular member has an interior passageway, a support structure affixed to the upper end of the tubular member, a shaft rotatably mounted in the support structure and extending downwardly through the interior passageway of the tubular member, and an auger connected to the shaft. A suitable hydraulic torquing tool can be connected to the shaft so as to cause the shaft to rotate for the purpose of rotating the auger. The auger is rotated so as to draw the tubular member into the subsea soil. The tubular member has a plurality of fins extending radially outwardly therefrom.

Auger anchor pile assembly and method of connecting anchor piles

A grease accumulator apparatus for use in subsea applications has a bottle with an internal chamber, a plunger positioned within the internal chamber and slidable therealong, and an end cap assembly affixed to one end of the bottle. The end cap assembly has an indicator member slidably connected thereto. The indicator member is cooperative with the plunger such that an end of the indicator member moves outwardly of the end cap assembly as the plunger moves in the bottle toward the end cap assembly. The end cap assembly has a body with a housing affixed to one end thereof. The housing has a hydraulic fluid inlet and a hydraulic fluid outlet. The indicator member is movable between a position in which the inlet and outlet are fluidically connected in a second position in which fluid flow is blocked between the inlet and the outlet.
