US Patent:

7798233, Sep 21, 2010

Filed:

Dec 6, 2006

Appl. No.:

11/567658

Inventors:

Jeremiah Daniel - Houston TX, US
Jin-Sug Chung - Katy TX, US
Ramanathan Ramaswamy - Katy TX, US
Joseph M. Gebara - Houston TX, US
John L. Upchurch - Sugar Land TX, US

Assignee:

Chevron U.S.A. Inc. - San Ramon CA

International Classification:

E21B 43/01

US Classification:

166363, 166366, 166367, 166369, 166350, 166352, 4052242, 405169, 441 3, 441 4, 441 5

Abstract:

The present invention relates to overpressure protection systems and methods for use on a production system for transferring hydrocarbons from a well on the seafloor to a vessel floating on the surface of the sea. The production system includes a subsea well in fluid communication with a turret buoy through a production flowline and riser system. The turret buoy is capable of connecting to a swivel located on a floating vessel. The overpressure protection device is positioned upstream of the swivel, to prevent overpressure of the production swivel and downstream components located on the floating vessel. The device may include one or more shut down valves, one or more sensors, an actuator assembly, and a control processor.

Abstract:

The present invention relates to overpressure protection systems and methods for use on a production system for transferring hydrocarbons from a well on the seafloor to a vessel floating on the surface of the sea. The production system includes a subsea well in fluid communication with a turret buoy through a production flowline and riser system. The turret buoy is capable of connecting to a swivel located on a floating vessel. The overpressure protection device is positioned upstream of the swivel, to prevent overpressure of the production swivel and downstream components located on the floating vessel. The device may include one or more shut down valves, one or more sensors, an actuator assembly, and a control processor. Each shut down valve and sensor is coupled to a production flowline. Each of the sensors is capable of generating a signal based upon a pressure sensed within the production flowline. The actuator assembly is connected to each of the shut down valves for operating the shut down valves. The control processor, which may be a programmable logic controller, receives a signal from the sensors and sends a valve control signal to the actuator assembly for operating the shut down valves in response to the received signals.

Michael Y.H. LUO - Bellaire TX, US
Zhengquan ZHOU - Houston TX, US

International Classification:

B63B 38/00

US Classification:

4051951

Abstract:

The present disclosure provides an improved design for a multi-sectional truss spar hull platform having a truss and a spar hull. One or more sections can be transported to a designated location and off-loaded into water from an available transport vessel. The truss includes a skirt tank at the upper end of truss that can be coupled to the lower end of the hull. The skirt tank can provide buoyancy during float-off and mating operations to the hull. The skirt tank is designed to allow the portion above the water to be coupled to the hull in a first orientation, the truss with the skirt tank rotated with the hull in the water to a second orientation to expose the previously underwater portion, and then the previously underwater portion can be coupled together above the water. The integral skirt tank will be flooded after the spar hull is up-ended.
