Floating fluid loading/offloading structure moored in a body of water, related installation, method and process

A method of installing a floating fluid loading/offloading structure moored in a body of water comprising:

• providing a hull extending longitudinally along a longitudinal hull axis, the hull comprising a bottom wall, a first lateral wall on a first side of the hull, a second lateral wall on a second side of the hull, opposite the first side, each of the bottom wall, first lateral wall, and second lateral wall being placed in contact with the body of water;
• providing a mooring equipment, comprising a first group of mooring lines connected to an anchor on the bottom of the body of water, the mooring lines of the first group protruding laterally beyond the first side, opposite the second side,
• the mooring equipment comprising a second group of mooring lines protruding laterally beyond the second side, opposite from the first side, and connected to an anchor located away from the second side;
• connecting the mooring lines of the first group above the surface of the body of water on the first side of the hull,
• providing a space facing the second lateral wall, and
• letting free of mooring lines the space facing the second lateral wall.
