PROBLEM TO BE SOLVED: To automatically collect fuel oil vapor while suppressing cost for capital investment.SOLUTION: An oil supply station system 1 comprises: a tank lorry 8 having an on-vehicle control device 10 for controlling start and/or finish of unloading of fuel oil from a fuel oil tank 9 mounting fuel oil; and a vapor collection device 2 comprising a compression pump serving as suction means for sucking and collecting fuel oil vapor in the inside of a ground tank and being disposed on a collection pipe branched from a vent pipe 17 whose one end is coupled to the ground tank, and condensation means coupled to a downstream side of the compression pump, and condensing the fuel oil vapor, and collecting the fuel oil vapor in the inside of the ground tank during unloading of the fuel oil mounted on the tank lorry 8. Based on an unloading start signal and/or unloading finish signal for indicating start and/or finish of unloading of the fuel oil output from the on-vehicle control device 10, start and stop of the vapor collection device 2 are controlled.SELECTED DRAWING: Figure 1 |
