摘要： A Christmas tree includes a main body, an bulkhead connector, a wet-mate connector, a cable, and a sensor. The main body has a first and a second main body end, and a further passage, and encloses a main passage. The further passage includes a first further passage end at a main body exterior and a second further passage end at the main passage, and extends from the first to the second further passage end. The bulkhead connector is secured to the main body exterior to close the first further passage end, and has a first and a second electrical connection. The wet-mate connector is mounted in the second further passage end to close the second further passage end. The cable transmits an electrical signal and connects the first electrical connection to the wet-mate connector. The sensor is arranged in the further passage and electrically connects to the second electrical connection.

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 fluid flow apparatus includes a body and an insulation system. The body has an exterior surface having a passage extending therethrough from a first to a second portion. The passage has first and second end portions adjacent to the first and second portions, respectively, and an intermediate portion extending between the first and second end portions. A cross-sectional area of the intermediate portion is larger than that of the first and second end portions. The insulation system has an outer and an inner liner. The outer and inner liners are arranged in the passage to engage with the body so as to line the passage and to provide a barrier between the body and a fluid flowing along the passage. The outer liner thereby engages with the body, and the inner liner is partially enclosed by the outer liner and the body at the first and second end portions.
