Appl. No.:

12/269015

Assignee:

Weed Instrument, Inc. - Round Rock TX

International Classification:

G08C 15/00

US Classification:

370223, 370222, 709251

Abstract:

Sets of communication modules each have a pair of ring-channel ports for a ring-configured channel in a network, a peripheral device port for peripheral device data, and dual-ring ports for an inter-ring channel for the pair of modules. First and second ones of a set of communication modules send duplicate data packets on their respective first and second rings. Responsive to duplicate data packets arriving via the rings at first and second modules in a next set within a predetermined time interval of one another, each of the next modules transmits its ring-channel received data packet out a downstream ring-channel port. Responsive to one of the duplicate packets arriving at the DRP of a module a predetermined time interval before arriving at a ring-channel port of the module, the module sends the corresponding packet received at the DRP out its other ring-channel port and its peripheral device port.

International Classification:

US Classification:

709251, 714717, 370222, 370223, 370224

Abstract:

Communication modules are coupled in a communication ring and are operable to send and receive data from peripheral devices. The modules are operable to send and receive data streams on paths of the ring, and each module is operable, responsive to receiving a predetermined initialization signal, to operate as a master for initially blocking data in the first path and initially sending a block signal to a neighboring module downstream in the second path. The modules are operable, responsive to receiving the block signal in one of the paths, to block data in that one of the paths, so that responsive to initialization of one of the modules as a master, the master and the neighboring module create an inactive virtual link therebetween in order to prevent data from propagating around the ring more than once.

International Classification:

E21B 33/035
E21B 33/038
E21B 33/043

Abstract:

A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. The subsea wellhead assembly may include a tubing hanger positioned in or below a wellhead housing coupled to a subsea well, a tree cap fluidly coupled to the tubing hanger and disposed atop the wellhead housing, and a pair of master production valves configured to be selectively actuated from an open position to a closed position to shut in the subsea well, each of the pair of master production valves located within or below the wellhead housing.

International Classification:

E21B 33/035
E21B 43/013
E21B 17/01

Abstract:

A subsea production system and method for installing the same are provided. The subsea production system includes a high pressure subsea wellhead, a tubing hanger landed proximate the wellhead, a production tree disposed above the wellhead downstream of the tubing hanger, a riser, a subsea flowline system coupled between the production tree and the riser, at least one barrier located downstream of the tubing hanger, and a secondary barrier valve disposed within the tubing hanger or in line with and upstream of the tubing hanger. The at least one barrier provides a pressure barrier that controls pressure of fluid flowing from components of the subsea production system located upstream of the barrier to components of the subsea production system located downstream of the barrier, and the secondary barrier valve is remotely actuable between a closed position and an open position.

Abstract:

In accordance with the present disclosure, a full top-to-bottom subsea system and method used to drill, complete, produce, and perform interventions on HPHT subsea wells is provided. The disclosed systems and methods involve the use of a controlled multiple barrier system, such as a high integrity pipeline protection system (HIPPS), incorporated into the subsea system to divide the system into two sections. The sections on either side of the barrier may be rated for different pressures, temperatures, and/or flow rates. For example, the first section (upstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a first (higher) threshold. The second section (downstream of the barrier) is rated for operating at pressures/temperatures/flow rates up to a second (lower) threshold. The disclosed subsea production system methodology, which uses barriers to divide the system components between two pressure ratings, may allow for enhanced development of HPHT reservoirs.

International Classification:

H04L 29/08
G05B 19/042

Abstract:

A technique for operating a communication system includes determining whether a specific node of the communication system is a start node. In response to determining the specific node is the start node, transmission of a header over a communication link of the communication system for each frame period is initiated. The frame period also includes a plurality of address segments each of which has an associated data number. In response to determining the specific node is the start node, data numbers for address segments are compared with associated I/O module address settings to determine if a data number is equal to one of the associated I/O module address settings. In response to determining the data number is equal to one of the associated I/O module address settings, transmission of node configuration and data from an input module (included in associated I/O modules) or zeroes for an output module (included in the associated I/O modules) is initiated.
