What 石油精製オペレーター do
An English description is being prepared. Japanese description:
石油の精製工程では、まず、原油を常圧蒸留装置でガス、ナフサ、灯油、軽油、常圧残油などに分ける。このままで製品となるものはほとんどなく、さらに、減圧蒸留、水素化精製、脱硫、接触改質、接触分解、水素化分解などの精製装置で処理して初めて製品となる。これらの石油精製装置は高度に自動化されており、コンピュータによって中央制御されているが、さらに無人化のシステム開発が進められている。
オペレーターの職場は現場と制御室に分かれ、現場の担当者「フィールドマン」は装置の巡回業務、制御室の担当者「ボードマン」は装置の制御が主な仕事になる。「フィールドマン」は装置の日常・定期点検を通して異常の早期発見、トラブルの未然防止や機器・設備の調整操作を行い、異常を発見すると素早く関連部署に連絡し、対応にあたる。「ボードマン」は通常は制御センター(計器室)内でコンピュータ画面を通じて装置の温度や圧力の変化などを監視し、異常を察知すると、現場と連絡を取りながらマニュアルにしたがって措置し、必要に応じて装置を安全に停止することで事故を防止する。

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 石油精製オペレーター? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 石油精製オペレーター
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.

Guidance from job tag (Japanese)
入職後は、半年から1年程度、石油精製プロセスの基礎教育を受ける。その後、各職場に配属され、数年間現場の経験を積み、作業手順や装置運転に慣れてくると、ボードマンとして精製工程を制御するようになる。そして「危険物取扱責任者」や「高圧ガス製造保安責任者」の資格を取得して、班長などに就く場合もある。転職や社内異動は少ないものの、精製装置の運転経験を生かし、製油計画や装置検査などの計画部門やエンジニアリング部門に異動することはある。
大きな災害につながる可能性のある危険物を扱うため、複雑な化学反応・作業工程のプロセスへの理解とともに、注意深く冷静な行動が必要となる。また、深夜勤務を含め労働時間が変則的なため一定の体力が求められる。化学・機械に興味を持ち、規則をよく守り、責任感のある人が必要とされる。
