摘要：Currently, corrosion of offshore crane booms is serious and badly affects equipment performance and working safety. Obviously, analysis of the corrosion is necessary. In this paper, as an actual case, the boom FEM of 320t pipe-laying crane is built to analyze its double points corrosion based on analysis of single point corrosion. By analyzing stress concentration and stress distribution of different distance for double corroded points, which can be axially arranged or circularly arranged, we try to obtain some affected trends. © (2014) Trans Tech Publications, Switzerland.
