Integrated Management System

The INK Group is among the leaders in the field of Integrated Management Systems (IMS). This status is confirmed by annual audits by DQS Holding GmbH — a world leader in the certification of industrial enterprises.

The Group activities comply with international standards ISO 14001:2015 (environmental management system) and ISO 45001:2018 (occupational health and safety management system).


In 2009, the INK Group approved its environmental policy, after which it was decided to gradually implement an integrated management system in accordance with international standards ISO 14001 and OHSAS 18001. Irkutsk Oil Company LLC has been preparing for this event for several years, changing its approach to social responsibility and HSE. In 2013, Irkutsk Oil Company LLC passed an external audit and received certificates of compliance with the IMS.

Certificates of conformity guarantee international recognition of audit results. It confirms reliability of the company as a business partner, confirmation of high-quality management and, consequently, the necessary condition for developing new markets and attracting investment.

In 2019, a certification audit was conducted for compliance with the requirements of ISO 45001, which replaced the OHSAS 18001 standard.

In 2021, the auditors noted the Group's significant results in the development of the IMS. Several Group companies have undergone independent evaluations: Irkutsk Oil Company LLC, INK-Service LLC, ToT LLC, and JSC INK-Zapad (all IMS certificates).

In the environmental area, the auditors noted the introduction of company’s in-house technology for the disposal of drilling cuttings with the production of composite soil, the creation of a special unit for waste management, the introduction of methods to assess the level of environmental culture and the use of detailed questionnaires to assess compliance with applicable legal requirements.

In the field of occupational safety, the following initiatives were noted: the INK Group joined the international Vision Zero concept to prevent occupational injuries; classification of contracts with contractors according to the degree of risk taken during operations; use of online platforms for safety trainings.

The annual confirmation of its international certification status is a guarantee that INK Group moves in the right direction and ensures HSE management according to state-of-the-art global standards.
