2.3.6 Environmental Management
Objective
To demonstrate sound environmental performance in all operational phases, by identifying
the environmental aspects (hazards) and controlling the environmental impact (risk) of
activities and services, and taking into account defined environmental policies and best
available practices and technology.
How can this be achieved?
‣ Ensuring that there are policies, objectives and plans (see Part 2.1 - Policies and
Objectives) that address the need to:
- comply with relevant environmental legislation, regulations and standards
- comply with contractual environmental requirements
- manage any significant adverse environmental impacts
‣ Ensuring environmental requirements are adequately addressed in the shared HSE
management processes and supporting documentation, e.g.:
- HSE plans and programmes
- job descriptions and responsibilities
- training and competence
- internal communication processes
- operational control procedures and work instructions
- identification of appropriate Key Performance Indicators
‣ Developing specific processes to support the implementation and delivery of the
environmental plans and programmes, e.g.:
- environmental monitoring plans
- measurement and estimation of discharges and emissions (including laboratory and
calibration procedures and identification of appropriate ‘emissions factors’, etc).
- spill preparedness and response plans
‣ Establishing a process for identifying all elements of the Rig services and activities that
can interact with the environment (environmental aspects).
‣ Recognizing the significance of the nature and location specific sensitivities of the
receiving environment in identifying significant adverse environmental impacts.
‣ Clarifying responsibilities with the client for identifying and assessing site-specific
environmental conditions.
‣ Co-operating with the client on establishing location, or well specific, significant adverse
environmental impact criteria.
‣ Reviewing the Rig environmental aspects against the site specific criteria and highlight
those that may result in a significant adverse environmental impact.
What in the Drilling Contractor’s Management System demonstrates assurance to others that
this objective can be achieved?
‣ Confirmation that environmental policies, objectives and targets are clearly defined
either as part of the organisation’s integrated HSE policies and objective statements, or
as separate documents.
‣ Confirmation that the HSE management processes and documentation shared between
the Drilling Contractor and the client take account of the environment.
