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.

Claims (6)

1. A system comprising:

a subsea well equipment landing body ( 1 ) comprising an indicator assembly to indicate landing of the landing body ( 1 ), wherein the subsea well equipment landing body ( 1 ) comprises a sliding stem ( 11 ) with a stem head ( 23 ) protruding beyond an external face of the landing body; and

a subsea well component ( 53 ) having a bore ( 51 ) configured to receive the landing body ( 1 ),

wherein the bore ( 51 ) having a locking profile ( 57 ) configured to engage with locking means ( 5 ) of the landing body, wherein the bore further comprises a landing indication profile ( 59 ) on a radially inwardly facing face of the bore and at a vertical distance from the locking profile ( 57 ), wherein the landing indication profile ( 59 ) is configured to receive the stem head ( 23 ), wherein the landing indication profile ( 59 ) has a finite extension in the circumferential direction of the bore such that the extension is smaller than the circumference of the bore, wherein the landing indication profile ( 59 ) is void (empty) when the stem head ( 23 ) is not received in the landing indication profile ( 59 ), and wherein the landing indication profile ( 59 ) does not form a channel through the wall forming the bore ( 51 ) of the subsea well component ( 53 ).

2. A subsea well component according to claim 1 , wherein the landing indication profile comprises a recess and wherein the recess is a circular hole.

3. A subsea well component according to claim 1 , wherein the sliding stem is configured to slide in a horizontal direction.
