摘要： Subsea well assembly having a Xmas tree (107, 207) and wellhead (103). From a tubing hanger (113) a tubing extends into the well. A part of a production flow passage extends vertically from the tubing hanger (113) in a vertical bore (111) of the Xmas tree. A fail close production master valve (PMV) (117) is arranged in the production flow passage. The tubing hanger (113) is arranged below the Xmas tree (107), such as in the wellhead (103). The Xmas tree (107) exhibits a branch (115) that deviates from the vertical bore (111), which branch constitutes part of the production flow passage. The fail close type production master valve (PMV) (117) is arranged in the branch (115).

摘要： A cable arrangement for feeding power and signals to downhole equipment, such as an electrically submersible pump (6), within an oil or gas well, comprising an upper suspension element (15), a lower connector (22), a docking station (11′) for the downhole equipment coupled to said connector (22), and a cable (8a), comprising lines for power and signal. The cable extends between, and is coupled to, the upper suspension element (15) and the lower connector (22). The docking station (11′) is adapted for attachment to the inner surface of a production tubing (5), that a narrow gap is formed between the production tubing (5) and the downhole equipment (6). The cable (8) is shaped to fit inside the gap by having a first dimension in the radial direction of the gap, which is smaller than the gap and a second dimension in the tangential direction of the gap, which is substantially larger than the first dimension.

摘要： A retrievable subsea apparatus (1) with a pressure and volume compensating system, the apparatus comprising: a housing (1′) having in its interior a control system (9) located in a first section (3) thereof and an operating unit (6) located in a second section (4) thereof. The apparatus further comprises a penetrator (2) which constitutes an interface between the first section (3) and the second section (4), wherein the first section (3) has a substantially constant first pressure. An external pressure compensator (5, 5′) is associated with the second section (4) having a second pressure. The operating unit (6) comprises at least a first sub-unit (6′) and at least a second sub-unit (6″). The second section (4) is subdivided into at least a first sub-section (4′) and at least a second sub-section (4″) which is sealed off from the first 1,1 section (4′) and being associated with respective sub-unit (6′, 6″).

摘要： A wellhead system includes a wellhead assembly which is generally tubular, a landing string assembly, and an orientation sensor assembly which is mounted on the landing string assembly. The wellhead assembly is secured to a top of a borehole and has an orientation engagement part. The landing string assembly is lowered into the wellhead assembly to land in the wellhead assembly. The landing string assembly has an orientation part with an orientation feature. The orientation engagement part of the wellhead assembly corresponds to the orientation feature. As the landing string assembly is lowered into the wellhead assembly, the orientation feature engages with the orientation engagement part to rotate the landing string assembly about its longitudinal axis into a desired orientation relative to the wellhead assembly. The orientation sensor assembly measures an angular rotation of the landing string assembly about its longitudinal axis.

摘要： A process system includes a process module, an upstream pipe, a downstream pipe, an inlet pipe with an inlet isolation valve, an outlet pipe with a discharge isolation valve, a bypass with a bypass isolation valve, and a drainage line with a valve. The process module has an inlet, an outlet, and a drainage outlet. The inlet pipe fluidically connects the inlet of the process module to the upstream pipe. The outlet pipe fluidically connects the outlet of the process module to the downstream pipe. The bypass fluidly connects the upstream pipe and the downstream pipe via the bypass isolation valve. The drainage line fluidly connects the drainage outlet of the process module to the downstream pipe via the valve.
