摘要
A corrosion protection system for protecting critical parts of an offshore structure. The structure is composed of an assembly of critical parts representing a small portion of the structure and noncritical parts representing a large portion of the structure. The critical parts are coated with a layer of material to form a protective treatment so that the critical parts are made electrochemically noble or passive relative to the uncoated noncritical parts when the offshore structure is submerged. The noncritical parts are electrochemically active relative to the coated critical parts to provide for cathodic protection current supplied to the coated critical parts by the uncoated active parts to produce corrosion protection to the coated critical parts. An accelerated corrosion system for destroying the critical parts uses a conductive layer including a slit and with the slit initially protected and then removed to accelerate corrosion to destroy the offshore structure.
