Abstract: 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.

Abstract: A connector unit is disclosed which comprises a shaft, a plurality of collet fingers, and a sleeve. The plurality of collet fingers are peripherally positioned against the generally cylindrical outside surface of the shaft adjacent the lower end of the shaft. The sleeve has an upper end, a lower end, and a generally cylindrical inside surface positioned peripherally around the shaft. The sleeve is provided with a radially inwardly extending annular flange extending from its inside surface between its upper end and its lower end which forms a seal with the generally cylindrical outside surface of the shaft. An upper annular chamber is formed between the generally cylindrical outside surface of the shaft and the generally cylindrical inside surface of the sleeve above the radially inwardly extending flange and a lower annular chamber is formed between the generally cylindrical outside surface of the shaft and the generally cylindrical inside surface of the sleeve below the radially inwardly extending flange.

Abstract: A coupling element is disclosed that is capable of axial and lateral movement for use in connecting fluid lines such as control lines used in subsea drilling. The coupling element has a male sealing element with a first end, a second end, and a longitudinal axis extending between the first end and the second end. The male sealing element defines a generally frusto-conical sealing surface. A fluid passageway for the transmission of fluids is defined through the male sealing element along the longitudinal axis. The generally frusto-conical sealing surface forms a metal-to-metal seal when mated with a female sealing element. A female sealing element with a sealing surface that is complementary to the generally frustoconical sealing surface of the male coupling element is also disclosed. The female sealing element forms a pressure energized metal-to-metal seal with the male sealing element when the two are mated. A poppet valve element may be positioned within the fluid passageway of the female sealing element.
