Recently, safety protection research on the risk of flammable gas leakage and deflagration between adjacent offshore facilities is easy to be ignored and the fire and explosion accidents are also harmful to interactive operations, causing great injury to personnel and damage to structures. In this paper, safety analysis of a flammable gas leakage and deflagration disaster is carried out on an FPSO and the semisubmersible support platform connected to it side by side. The diffusion mechanism of the flammable gas between adjacent facilities is explored with CFD method. The integrated consequences assessment of indirect deflagration determines the accident characteristics of the leaking facilities under different scenarios, which support the continuous leakage under fire and explosion disasters. An engineering reference is provided for the design of safe docking between offshore support platforms and oil and gas production, storage and transportation facilities and adjacent support facilities. 2020, 2020 Informa UK Limited, trading as Taylor & Francis Group.
