Appl. No.:

10/258512

Inventors:

Larry Russell Jordan - Houston TX

Assignee:

Cooper Cameron Corporation - Houston TX

International Classification:

E21B 1909

US Classification:

166355, 114264, 166367, 175 5

Abstract:

A riser recoil control system ( ) adjusts tension forces (F , F ) applied to a marine riser ( ), which is attached to an anchored, floating vessel ( ) and a wellhead ( ). The riser ( ) is attached to the vessel ( ) using tension forces (F , F ) asserted by riser tensioners ( ). Each tensioner ( ) has an air shutoff valve ( ), and an orifice-controlled fluid valve ( ). A disconnection sensing means ( ) provides a disconnect signal when the riser ( ) is disconnected from the wellhead ( ), which closes the valves ( ) and adjusts the tension forces (F , F ) applied by the tensioners ( ). The invention includes a method for adjusting the tension forces (F , F ) applied to the riser ( ), including sensing the disconnect signal and adjusting the tension forces (F , F ) supplied to the riser ( ) by closing the air shutoff valves ( ) and partially closing the orifice-controlled fluid valves ( ).

Appl. No.:

10/240994

Inventors:

Larry Jordan - Houston TX, US

International Classification:

B63B027/00

US Classification:

414/138200

Abstract:

The active deployment system (′) comprises a passive cylinder system () coupled with an active cylinder system (). The passive cylinder system () including a pre-charged accumulator (), provides load balance for the equipment or other mass/load being deployed. Pressure provided to the blind end of the passive cylinder supports the load (), such that the passive cylinder is balanced mid-stroke with the load hanging from a cable (). A sheave arrangement (), placed at opposite ends of the passive cylinder-active cylinder combination, is used to introduce a line travel multiplier for cylinder displacement. The active cylinder is controlled hydraulically to add or remove load to/from the passive cylinder system in order to provide a compensating balance. The method comprises the steps of measuring a heave movement (velocity and direction), and adjusting the tension force applied to the cable () upon determining that the heave velocity exceeds a pre-selected critical velocity.

Appl. No.:

6/761585

Inventors:

Larry B. Jordan - Houston TX

International Classification:

B25B 2500
B66D 150

US Classification:

254228

Abstract:

A hydropneumatic cable tensioner is comprised of an enclosed cylinder featuring a plurality of annular chambers. A fixed cable sheave is mounted to one end of the cylinder. A movable cable sheave is mounted to a piston rod connected to a piston which reciprocates in a piston bore chamber of the cylinder. Regulated compressed gas is connected to the outer accumulator chamber of the cylinder thereby exerting high pressure forces on oil found in the middle or high pressure oil chamber of the cylinder. Pressurized oil forces a piston to move outwardly thereby increasing the distance between the two sheaves and tensioning a cable and containment chamber within the piston rod. Restriction ports between the piston bore chamber and the containment chamber within the piston rod regulate movement of the piston and prevent uncontrolled acceleration should a cable failure occur.

Abstract:

A hydropneumatic cable tensioner is comprised of an enclosed cylinder featuring a plurality of annular chambers. A fixed cable sheave is mounted to one end of the cylinder. A movable cable sheave is mounted to a piston rod connected to a piston which reciprocates in the innermost or piston bore chamber of the cylinder. Regulated compressed gas is connected to the outer chamber of the cylinder thereby exerting high pressure forces on oil found in the middle or high pressure oil chamber of the cylinder. Pressurized oil forces a piston to move outwardly thereby increasing the distance between the two sheaves and tensioning a cable. Restriction means within the piston bore chamber regulate movement of the piston and prevent uncontrolled acceleration should a cable failure occur.
