Flexible line installation and removal

A method of removing a flexible line deployed between an offshore platform and a subsea structure, where the platform has a landing deck on which the flexible line is installed, the landing deck facing away from the platform towards an installation side, the method comprising:

• decoupling a topside end of the flexible line from the landing deck;
• lowering the topside end from the landing deck to the sea bed using a platform mounted winch, and detaching the winch from the topside end;
• moving the platform in a direction away from the installation side and away from the topside end and positioning an installation vessel on the installation side by moving the installation vessel towards the subsea structure;
• lowering a recovery line from the installation vessel and attaching an end of the recovery line to the topside end of the flexible line or a subsea end of the flexible line;
• raising the attached topside or subsea end onto the installation vessel from the seabed using the recovery line;
• and
• recovering the flexible line onto the installation vessel,
• whereupon the platform can be moved back to an operating position located substantially above the subsea structure.
