OIMS

OIMS Logo

ExxonMobil's policies on safety, health, the environment and product safety reflect our commitment to the highest operational standards and performance, and to conducting business in a manner that is compatible with the environmental needs of all communities in which we operate. We employ a disciplined, systematic approach that we call OIMS (Operations Integrity Management System), which has been in place since 1992.

ExxonMobil developed this system to provide a robust framework for managing safety, security, health and environmental risks. It is used in our facilities worldwide and enables us to measure progress, ensures management accountability for results and establishes common worldwide expectations for controlling operations integrity risks inherent in our business.

OIMS also ensures engagement with the communities in which we operate, through activities such as conducting social and environmental impact assessments for new projects. OIMS is structured to meet our corporate requirements, industry initiatives such as Responsible Care®, government regulations and to be flexible enough to adapt to change.

The independent assessor, Lloyd's Register Quality Assurance, has attested that OIMS is consistent with the intent and meets all requirements of the International Organization for Standardization's standard for environmental management systems--ISO 14001.

How does OIMS work?
The OIMS process requires continual evaluation and improvement of management systems and standards, as well as the involvement of our employees. It has established a common language for discussing and sharing successful systems and practices among different parts of ExxonMobil's business.

The OIMS framework has 11 elements, each with clearly defined expectations that every operation must fulfill. Management systems put into place to meet OIMS expectations must show documented evidence of the following five characteristics:

  • The scope must be clear and the objectives must fully define the purpose and expected results.
  • Qualified people are accountable to execute the system.
  • Documented procedures are in place to ensure the system functions properly.
  • Results are measured and verified that the intent of the system is fulfilled.
  • Performance feedback from assessment and verification and measurement activities drive continual improvement of the system.

OIMS requires each operating unit to be assessed by experienced employee teams from outside that particular unit approximately every three to five years. Self assessments are required in the other years.

For a more detailed explanation of how these elements work in practice, see our publication Operations Integrity Management System.
