Abstract: A bore selector for use with a monobore riser and a multi-bore subsea system having a production bore and an annulus bore. The bore selector has a housing extending in a longitudinal direction and a bore selector element rotatably mounted to the housing and is rotatable about an axis which extends substantially transverse to the longitudinal direction. The bore selector element may comprise a ball element, or a cylindrical element. The bore selector element has a first passage extending through the bore selector element and is configured to connect the monobore riser to the production bore at a first rotational position of the bore selector element, and a second passage extending through the bore selector element and is configured to connect the monobore riser to the annulus bore at a second rotational position of the bore selector element. The first and second passages may intersect within the bore selector element.
