Basic Policy

INPEX has issued an HSE Policy to ensure the safety and health of all those involved in our business activities while striving for the conservation of local ecosystems and the global environment. To implement this policy firmly, we promote HSE management through the HSE Management System.

Occupational Health and Safety

We aim to eliminate incidents to ensure that all workers at INPEX worksites return home safe and sound each day. We also take measures against potential illness and hygiene issues employees may face to keep employees healthy.

Process Safety Management

In order to prevent major incidents or disasters such as fires, explosions or large oil spills, we consider safety throughout each phase of the project life cycle: exploration, development, production and abandonment.

Security and Crisis Management

We reinforce the management of overseas security as necessary by considering the recent security circumstances. We also prepare the necessary documents to respond to various types of emergencies, and conduct crisis management exercises to prepare for the worstcase scenario.

Environmental Management

We strive to minimize negative impacts on the environment and local communities by conducting environmental and social impact surveys before starting a project, monitoring those impacts through the project’s lifecycle, and promoting environmental management based on the monitored results.

Five-Year Plan

The Corporate HSE Third Phase Mid-term Plan (FY2016–2020)

The following targets have been set for achieving the mid-term plan:

  1. We will introduce the guideline (OMS 510*5) newly developed by IOGP*6 to our HSEMS in order to improve efficiency and consistency, and apply updated HSEMS to activities undertaken at all INPEX Group, including non-operator projects and domestic subsidiaries.
  2. We will conduct HSE audits and reviews systematically and progressively with companywide cooperation. By utilizing the results from these audits and reviews, we will enhance companywide HSE assurance and governance.
  3. We will enhance HSE technical support by appropriating companywide resources.
  4. Recognizing HSE management on a site basis is extremely important, so we will create a structure in which every individual employee on site is able to participate in HSE activities and incorporate his/her own experiences and ideas into the structure.
  5. We will thoroughly manage major accident event prevention through strengthening HSE risk control, reinforcing the Safety Case approach, as well as process safety management and various activities to maintain integrity of facilities and equipment.
  6. We will introduce a new companywide leading indicator additional to LTIR and TRIR, which will be continuously monitored and evaluated, thereby positioning ourselves in the top 25% of the IOGP member companies.
  7. We will fortify the Incident Command System companywide to respond to emergency and crisis situations with speed and appropriate actions.
  8. We will ensure that environmental and social issues are managed based on legal requirements and the IFC Performance Standards. We will select issues that will contribute to lower environmental load and develop plans to manage them as we continue the greenhouse gas management.

Case Study

Exploratory Offshore Drilling without Major Incident

Drilling operations on an offshore exploratory well near Shimane and Yamaguchi prefectures were commissioned by the Agency of Natural Resources and Energy of the Ministry of Economy, Trade and Industry (METI) of Japan for the agency’s “Heisei 26-28 (2014- 2016) Domestic Offshore Drilling Program in Japan” and with the understanding and cooperation of local communities. We completed the drilling operations safely without any major incidents or disasters.
The project started with the logistics terminal in March 2016 around Hamada City, Shimane Prefecture, offshore of Shimane and Yamaguchi Prefectures, and ran for approximately eight months to the demobilization of the rig in late October 2016.
In these offshore drilling operations, we not only complied with domestic laws and the HSE requirements of INPEX and the stakeholders, but, together with a foreign drilling contractor (Transocean Ltd.), we also practiced HSE management that introduced international practices. We assembled a number of partner companies (including Japanese and foreign companies) and managed on site operations safely.
