Inventors:

- Houston TX, US
Frank Benjamin Springett - Spring TX, US
Travis James Miller - Cypress TX, US

International Classification:

B66C 23/06
B66C 23/52
B66C 23/82

Abstract:

Cranes and crane systems with high capacity lifting capabilities, as well as versatility and relatively large operational areas. A crane of the present disclosure may have main boom pivotable about a substantially horizontal axis and a luffing assembly configured for luffing the boom about the axis. The main boom may be pivotable in both a forward luffing operation and a reverse or rearward luffing operation. In this way, the main boom may be operable within a range extending up to 180 degrees. Various adjustment mechanisms may be used to shift the main boom from a forward luffing operation to a reverse luffing operation. Additionally, a crane of the present disclosure may have a utility boom rotatable about a substantially vertical axis. The utility boom may allow for added lateral reach of the crane, thus further increasing the operational area of the crane.

International Classification:

E21B 19/15

Abstract:

A system for handling tubulars on a rig may include a top handling device configured for arrangement on the rig and for handling a top portion of a tubular to and from a setback area. The system may also include a lower handling device configured for arrangement on the rig and for handling a bottom portion of the tubular between well center and a release position. The system may also include a bottom handling device configured for arrangement on the rig and for handling the bottom portion of the tubular between the release position and the setback area.

Inventors:

- Houston TX, US
Frank Benjamin Springett - Spring TX, US
James William Weir - Houston TX, US
Travis James Miller - Cypress TX, US
James Landrith - Humble TX, US

International Classification:

F15B 11/08

Abstract:

Hydraulic circuits for controlling a movable component use one or more of a plurality of fluid supplies. Pressurized fluid flowing from one supply is routed toward the component and is not inadvertently vented into another fluid supply, or into an exit port. A backflow path is provided for fluid returning from the hydraulic component when the component is actuated in a reversed direction. The hydraulic circuits can be used, for example, on blowout preventers in a subsea environment.

International Classification:

F16K 31/124
F16K 27/04
E21B 34/02
F16K 11/065

Abstract:

The disclosure provides devices and methods for controlling the actuation rates of SPM valves by bi-directionally controlling the fluid which actuates the valve or by maintaining enclosed volumes which communicate with each other thru predetermined restrictions as the valve actuates. These enclosed volumes can be completely isolated, depth compensated, share fluid with the pilot actuating fluid, or utilize the main system fluid. The restrictions can be modified to increase or decrease the actuation rates of the SPM valve. The disclosure also provides control over the main system fluid passage opening and closing positions as well as how rapidly the flow passage areas increase or decrease while opening or closing the valve.
