The present invention relates to a hydrocarbon production inline manifold system. The inline manifold system includes a carrier pipe with a longitudinal carrier pipe axis. The carrier pipe is provided with a plurality of hubs each with a jumper port. A hub longitudinal axis is arranged perpendicular to the carrier pipe axis. The hub longitudinal axes of the plurality of hubs are in a common plane with the carrier pipe axis. A flow line is located inside the carrier pipe. At least one valve is located in a flowpath between each of the plurality of hubs and the flow line.

The present invention provides a nonresident system for depressurizing subsea apparatus and lines comprising a depressurizing tool (5) adapted for being coupled to an ROV interface (6) of a subsea apparatus, wherein the depressurizing tool (5) is coupled to an ROV (4), wherein: the ROV interface (6) comprises a first pipeline (6a) for connection to a first hydrocarbon transport line (8), a second pipeline (6b) for connection to second hydrocarbon transport line (9), and a connection mandrel (6d); and the depressurizing tool (5) comprises a suction line (5a) adapted for being connected to the first pipeline (6a) for connection to the first hydrocarbon transport line; a discharge line (5b) adapted for being connected to the second pipeline (6b) for connection to the second hydrocarbon transport line; a pump (5c); and a connector (5d) adapted for being connected to the connection mandrel (6d) of the ROV interface (6). A method is also provided for depressurizing subsea apparatus and lines, comprising the steps of: removing a blind cap (15) from an ROV interface (6) with aid of an ROV (4); coupling a depressurizing tool (5) to the ROV interface (6) of a subsea apparatus (10); suction and removal of fluid from a first hydrocarbon transport line, wherein the first hydrocarbon transport line comprises hydrate formation; and pressurizing and reinjecting the fluid into a second hydrocarbon transport line.

A valve block may be provided with a plurality of flow bores within a body the valve block. In addition, valve block may have a plurality of openings opening at an outer surface of the valve block and in fluid communication with the plurality of flow bores. Further, a blind plug may be within at least one of the openings. The blind may include a cap coupled to an inner surface of the at least one opening and a plug having a first end face in contact with the cap and a second end face extending into the flow bore. Furthermore, the blind plug may seal the at least one opening from a surrounding environment.

A subsea production system for producing fluids from a subsea well in a subsea field. The production system includes a production facility and a production umbilical connecting the subsea well with the production facility. The production system also includes a control system for controlling production from the subsea well. The control system includes a first redundant master control station system (redundant MCS) at a first location, the redundant MCS capable of controlling production from the subsea well. The control system also includes a second redundant MCS at a second location, the second redundant MCS capable of controlling production from the subsea well. The redundant MCSs are synchronized to keep the same electronic data at both locations and to prevent conflicts in control signals from the redundant MCSs.
