The sliding way beam is an important tool for the disassembly and the maintenance of the offshore platform. It differs greatly in structure due to the particularity of various platforms, resulting in extremely complex strength check. This paper performs the numerous mechanical analyses of the sliding way beam system, and makes reasonable simplification of the complex mechanical model from the engineering viewpoint. It deduces the general equation for the check of the sliding way beam according to the ultimate bearing capacity of the steel structures, which can provide the reasonable computational basis for the engineering design.
