Abstract
A method of determining fuse parameters in a reciprocating gas compressor ensures a safe failure upon exceeding an overload limit. Stresses and bolted joint behavior for critical components in compressor running gear are evaluated using a finite element analysis. Capabilities of the critical components during an overload event are evaluated using a propagation and variances tool. The capabilities of the critical components are compared against overload conditions. At least one of an optimal fuse location and a fuse geometry are determined according to the comparison to establish a safe failure point upon exceeding the overload limit. With a mechanical fuse defining a failure point, critical compressor components can be protected from damage, and personnel can be protected from risk of a gas leakage.
