To provide a distributed production system to produce crude oil by thermally cracking a raw material such as palm cluster at a production site or the like, and to collect the crude oil and efficiently produce a bio-diesel fuel oil.

The system includes: a crude oil production facility (30), installed at a production site of the raw material or a cargo collection site thereof and equipped with a thermal cracking tank (11) cracking the raw material to extract thermally cracked gases, a condenser (13) condensing thermally cracked oils from the thermally cracked gases of the thermal cracking tank to produce crude oil, and a crude oil tank (1) storing the produced crude oil; a fuel oil refining facility (31), installed at a refining site different from the production site or the collection site and equipped with a crude oil tank (15) storing the transported crude oil, a distillation tower (16) distilling medium oils from the crude oil, and a refiner (17) refining the medium oils; and a crude oil transport means (32) transporting the crude oil from the crude oil production facility to the fuel oil refining facility.
