Abstract
A subsea well equipment landing body (1) comprising 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.
