Health, Safety and Environment (HSE) Policy

As a challenger to the deep sea science frontiers, we may operate even under harsh sea conditions and drill into unknown lithologies and structures which oil and gas drilling does not normally encounter. We believe that scientific success can only be achieved on the basement of the safe and environment-friendly operations. Here we have established our HSE Policy in order to make it our common goal and to provide the best working environment to realize it.

CDEX HSE management system

CDEX has established the Health, Safety, and Environment Management System (HSE-MS) for safe and high-quality scientific drilling operations. The HSE-MS is an international standard in offshore drilling societies which is a voluntarily established rules and procedures to materialize HSE to which the organization commits. The HSE-MS is characteristic in terms of the process approach: proper process management is more emphasised in HSE-MS rather than focusing on the outcomes.
CDEX has established the HSE-MS and conducts operations at the planning, implementation and review stages of drilling projects in accordance with the system requirements. Specifically, we develop an operation plan based upon identification and management of risks at the project planning stage, and implement operations following the plan.

CDEX HSE-MS

At the core of the system lies a cycle of continual improvement (PDCA cycle). A review is carried out upon completion of each project as to evaluate whether identified risks and their control measures were appropriate and effective, and the lessons learnt through project are accumulated and utilized in the future. Then, our project management will be improved and enforced through the PDCA cycle.

Occupational Health and Safety - Our number one priority

The HSE-MS considers the safety of all personnel under the control of CDEX. People covered include CDEX employees, of course, as well as the offshore and onshore contractor personnel (including sub-contractors), on-board researchers, and temporary visitors. Risk assessment for incident-free workplace is carried out in consideration of operation details, human and other factors, and provides necessary risk control measures (e.g., development of procedures and rules, education & training, management and supervision of contractors) are taken.

Environmental Protection - for our irreplaceable oceans and the Earth

CHIKYU is a scientific research vessel for explore oceans, and we believe our research activities should not give negative impacts to the environment. Nevertheless, our research involves drilling deep into the seafloor associated with sample collection and equipment deployment, and thus some impact to the environment is inevitable. Therefore, CDEX assesses environmental impacts due to drilling and the related operations in advance (environmental assessment) and make appropriate measures to minimize the impact.

Our environmental conservation effortsOur environmental conservation efforts

The identified environmental aspects may include those associated with routine operations such as fuel consumption and emissions to the atmosphere and oceans, and significant environmental aspects those resulted from incident. We also believe that communications of environmental risks with the external communities is important.

Keeping high operation quality - all for the researchers

Process management for safe and environment-friendly operations may also lead to the high operation quality. Through high-quality operations such as completion of boreholes that meet the requirements of the research community and providing high-quality samples and data, we hope to contribute to the attainment of project scientific goals. To this end, identification and control of the expected operation troubles are conducted as is done for safety and environmental risk management. After completion of the project, their appropriateness and effectiveness are reviewed and the lessons and tips are accumulated.
