8. Gen. condition Structurally sound buoy with of course some wear and tear around the hull, but nothing serious. Skirt slightly damaged; bearings maintained, swivel tba. Minor physical damage to superstructure.
As buoy has been stored and maintained professionally, the condition is as one can expect. My personal verdict is that buoy need some checks and will be ready for a 3 to 4 year operation after some superficial repairs and site preparation (adaption: spools etc), alt. for 10 to 15 years after a full refurbishment.
