An automated riser recoil control system ( ) including a plurality of riser tensioners ( ), a vessel heave measurement system ( ) and a control processor ( ) with each tensioner ( ) having a piston travel indicator ( ) which signals the processor ( ) and a method of operation is disclosed.
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 ( ).
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.
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.
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.

Abstract:
A method and apparatus for cleaning, and removing contaminants from the interior of a lubrication rundown tank of a mechanical system provides a source of pressurized and heated cleaning fluid containing at least one solvent; a first jumper hose communicating between the source of pressurized cleaning fluid and the interior of the lubrication rundown tank; a second jumper hose communicating between the interior of the lubrication rundown tank and a dirty fluid collection body; and an outlet spray nozzle carried by a nozzle extension placed within the interior of the lubrication rundown tank and in fluid communication with the source of pressurized and heated cleaning fluid to receive the pressurized and heated cleaning fluid therefrom.
