Abstract Fires in very large oil tanks are suppressed by injecting foam into the annular seal ring around the top until the ring is completely filled with foam. However, most of the foam ends up on the unburned area which does not control the fire and results in insufficient supply to the fire region. This paper presents a partition fire extinguishing plan for very large oil tanks that is more efficient and reduces foam use without changing the existing oil tank structure or the fire control system. The scheme was evaluated using an annular oil pan and a small external floating roof oil pan for experimental research on the foam fluidity and partitioned fire control. The results compare the effective covering time, the amount of foam and the fire control time. The results show that the foam spillover into different regions is directly related to the gap width and is not related to the oil pan shape and size. The results also show that the fire control time is shorter when using partitioned areas rather than the unpartitioned design. The partitioned fire control method then reduces the foam use by more than 60%. Experiments with a 3 m diameter oil tank fire are consistent with the results of the annular oil pan experiment, which shows that the advantages of zonal fire control are not related to the tank size and that the partitioned fire control scheme can be applied to very large oil tanks.
