Subsea horizontal connection arrangement

A horizontal connection arrangement for subsea connection of a first single bore or multibore hub arranged on a first subsea module of a subsea oil and/or gas production system or subsea water and/or gas injection system to a second single bore or multibore hub arranged on a second subsea module of the system, the horizontal connection arrangement comprising:

• a first connection appliance mounted to the first subsea module, wherein the first hub is fixed to a first holding unit included in the first connection appliance;
• a second connection appliance mounted to the second subsea module, wherein the second hub is fixed to a second holding unit included in the second connection appliance;
• and
• a connector configured to connect and secure the first hub to the second hub, wherein
• the first connection appliance comprises a sliding unit which is slidably mounted to the first holding unit so as to be horizontally moveable in relation to the first holding unit and the first hub in the axial direction of the first hub;
• the connector is mounted to the sliding unit so as to be horizontally moveable together with the sliding unit in relation to the first holding unit and the first hub between a retracted position, in which an outer end of the first hub projects beyond a front side of the connector, and an advanced position, in which the outer end of the first hub is received inside the connector;
• and
• the first holding unit is slidably mounted to a base frame of the first subsea module to allow the first holding unit to be moved in relation to this base frame in a horizontal direction from a retracted first position to an advanced second position and thereby bring the first hub into contact with the second hub.

• and
• the sliding unit and the second holding unit comprises corresponding alignment members, which are configured to come into contact with each other in order to align the first hub with the second hub when the first and second hubs are moved horizontally into contact with each other.
