operational excellence
management system

In 2004, we launched our Operational Excellence Management System (OEMS), a comprehensive system that helped build our Operational Excellence (OE) culture and improve our health, environment and safety performance. Our recently updated OEMS features more visible linkages between risk, assurance and safeguards and contains a streamlined approach to manage risk. These updates help increase our focus on preventing high-consequence incidents and impacts.

safeguards are at the heart of OEMS leadership and OE culture

Through the OEMS, our leaders engage employees and contractors to build and sustain our OE culture and deliver OE performance.

focus areas and OE expectations

Focus areas align with critical OE risks and include:
• Workforce safety and health
• Process safety, reliability and integrity
• Environment
• Efficiency
• Security
• Stakeholders

The OE expectations guide us to design, manage and assure the presence and effectiveness of safeguards.

management system cycle

Through application of the Management System Cycle, our leaders make risk-based and data-driven decisions, prioritise activities and direct improvements.

risk management

OEMS is a risk-based and systematic approach to identify, assess, prioritise and manage OE risks.


We establish and sustain safeguards and assure they are in place and functioning in accordance with legal and OE requirements.

Safeguards are the hardware and human actions designed to directly prevent or mitigate an incident or impact. Typical safeguards include facility designs, mechanical devices, engineered systems, protective equipment and execution of procedures.


Through the execution of assurance programs, we have confidence the safeguards are in place and functioning.
OEMS manage safeguards

We focus on preventing high-consequence incidents and impacts by understanding and mitigating risks and maintaining and assuring safeguards.

We develop energy in an environmentally responsible manner across the life of our assets.  Chevron North Sea has been ISO 14001 certified since February 2000.  In 2017 the company achieved certification against the updated ISP 14001:2015 standard.

We also work closely with government, communities, regulators and other industry members to seek visible solutions that meet the highest standards of environmental stewardship. In compliance with the U.K. Department for Business, Energy and Industrial Strategy (BEIS) requirements, we submit an annual environmental management system public statement which is published here

At every stage of every project, the safety of our people and protection of the environment remain our focus. Rigorous and thorough assessments are undertaken to mitigate environmental impacts, reinforcing our commitment to environmental management and stewardship.
