摘要： An assembly includes two tubular elements, a primary and a secondary seal arranged between the two tubular elements, a seal cavity formed between the two tubular elements and the primary and the secondary seal, and a seal monitoring apparatus having a housing and a position sensor. The housing has a chamber enclosing a separator which divides the chamber into a first and a second sub-chamber. The first sub-chamber is fluidly connected to the seal cavity and is filled with a hydraulic fluid. The separator is movable in a first direction relative to the housing to increase a volume of the first sub-chamber and decrease a volume of the second sub-chamber, and in a second direction to decrease the volume of the first sub-chamber and increase the volume of the second sub-chamber. The position sensor generates an electrical signal which represents a position of the separator relative to the housing.

摘要： An offshore power distribution system includes first cables each having a first dry mate connection at a first end and each connecting to an offshore power generator unit at a second end, a subsea junction box at a sea floor, a second cable extending from the junction box to a subsea transformer station at the sea floor and connecting with the transformer station, and a third cable extending from the transformer station to an onshore receiver. Each first dry mate connection terminates in the junction box. The second cable has a second dry mate connection at an end thereof. The second dry mate connection terminates inside the junction box and is operatively connected to each first dry mate connection. The power distribution system is configured to transmit electric power from the power generator unit, via the first cables, the second cable, and the third cable, to the receiver.

摘要： A subsea well equipment landing body (1) includes an indicator assembly to indicate landing of the landing body or to indicate locking of the landing body. The indicator assembly has a stem bore (7), a sliding stem (11) within the stem bore that has a stem head (23) protruding beyond an external face of the landing body. A stem channel (25) in the sliding stem extends between the stem head and a stem channel mouth (27), and is in fluid communication with the outside of the landing body. A hydraulic channel (9) in the landing body is in fluid communication with the stem bore. The stem channel mouth is positionable in a communicating position, in which there is fluid communication between the hydraulic channel and the stem channel, and a non-communicating position, without fluid communication between the hydraulic channel and the stem channel.

摘要： The invention provides a cutting valve comprising a valve block, a gate, which is slidably within a cavity in the valve block from an open position to a closing and cutting position, an upper seat arranged in an upper part of the valve between the valve block and the gate, and a lower seat arranged in a lower part of the valve between the valve block and the gate, The valve further comprises an upper resilient member arranged between the upper seat and a lower resilient member arranged between the valve block and the lower seat. The cutting valve being distinctive in that the combination of height of upper seat, and lower seat, resilient member and any spacers on the lower side of the gate is selected so that an allowed travelling distance for the upper seat towards the valve block and an allowed travelling distance for the lower seat towards the valve block, are substantially equal.
