HSQE ポリシー

Health, Safety, Quality & Environment Policy

MANTLE QUEST JAPAN (“MQJ”)’s goal is to maintain and improve the health and safety of all employees, safe drilling and marine operations of the CHIKYU, whilst also recognising the importance of environmental preservation, subsequently providing high-quality of services as required by our customers.

We commit to sustainably conducting operations and business to contribute to society, and recognise that health, safety, environmental preservation, and quality assurance are essential factors.

To achieve such goals, MQJ has developed and implemented an integrated HSQE Management System (“HSQE MS”) conforming to the ISM Code, industry best practices, client preferences, and the relevant international and domestic regulations.

I will ensure that we continue to provide the necessary education and training programs, and management guidance in connection with the HSQE MS for all employees. Also, I request that employees always perform their respective duties in accordance with the HSQE MS Manual and other related documents.

All employees are entitled to stop or suspend any work being conducted if they observe health, safety, environmental, or quality assurance risks that are not adequately controlled, also to demand the re-evaluation of those risks and take preventive measures based on the HSQE MS.

I am confident that all employees will accomplish their respective duties with zero incidents by respecting and following the HSQE MS.

In closing, the ultimate responsibility for implementing the HSQE MS rests with me as President of MQJ.
