Connection System for Subsea Connection of a Subsea Umbilical to a Subsea Appliance

A connection system for subsea connection of a first subsea umbilical to a subsea appliance in the form of a second subsea umbilical or an umbilical termination assembly, wherein the first subsea umbilical and the subsea appliance comprise several fluid conduits, the connection system comprising:

• a termination box fixed to an end section of the first subsea umbilical, the termination box comprising a front end and an opposite rear end, wherein the first subsea umbilical extends through an opening at the rear end of the termination box;
• a first umbilical coupling part mounted to the termination box at the front end thereof, this coupling part comprising several first coupling members, each of which being connected to one of the fluid conduits of the first subsea umbilical;
• a second umbilical coupling part which is connectable to the first umbilical coupling part and comprises several second coupling members, each of which being connected to one of the fluid conduits of the subsea appliance and being configured to engage with one of the first coupling members when the first umbilical coupling part and the second umbilical coupling part are connected to each other;
• a connection unit, the termination box being slidably mounted to the connection unit so as to be axially displaceable in relation to the connection unit;
• a landing unit, which has a fixed position in relation to the second umbilical coupling part, wherein the connection unit is connectable to the landing unit by being lowered downwards into contact with the landing unit, the connection unit being provided with guide members configured to co-operate with corresponding guide members on the landing unit so as to guide the connection unit into a correct position in relation to the landing unit when the connection unit is lowered downwards into contact with the landing unit;
• and
• an actuating unit configured to displace the termination box and the end section of the first subsea umbilical axially forwards in relation to the connection unit so as to bring the first umbilical coupling part into contact with the second umbilical coupling part.
