The work in an ocean oil field is very dangerous and there are many accidents. So there are demands for taking suitable measures against the hazards. Deflagration of inflammable crude oil gas is one of the major accidents. There are many studies and experiments regarding deflagration for gas-air mixtures on a small scale. But, there are only a few cases studied on a large scale, and the phenomenon is not clear enough. This paper presents a pressure calculation method when deflagration occurs in a mud treatment room in a semi-submersible drilling rig for the development of useful calculation tool for basic design.
