OSPAR HOCNF Compliance for Offshore Chemicals

Overview of OSPAR and HOCNF

Offshore chemicals are substances intentionally used in connection with offshore exploration and production activities in maritime areas. These chemicals include both individual substances and complex preparations. To manage and reduce the discharge of these chemicals into the marine environment, the OSPAR Commission established Decision 2000/2, which introduced a Harmonized Mandatory Control System.

A key component of this system is the Harmonized Offshore Chemical Notification Format (HOCNF). This format provides national authorities with essential data on the chemicals intended for use or discharge offshore. Based on the information provided by chemical suppliers, regulatory bodies perform pre-screening and implement necessary measures, such as issuing discharge permits, to protect the marine environment of the North-East Atlantic.

Proregulations offers professional technical guidance to help offshore chemical suppliers navigate these maritime regulations and ensure full compliance with OSPAR standards.

Scope of the HOCNF Framework

The OSPAR mechanism involves fifteen governments of the western coasts and catchments of Europe, along with the European Union. Together, they cooperate to protect the North-East Atlantic through the OSPAR Convention. The HOCNF format applies to all chemicals used in offshore exploration and production activities within this designated maritime area.

Compliance is mandatory for any offshore chemical supplier placing products in the North-East Atlantic region of the fifteen OSPAR contracted governments. The requirements apply to operational chemicals, including contingency chemicals used to maintain pipeline integrity, which may result in discharges. Examples of covered chemicals include:

• Rig and turbine washes and pipe dopes.
• Hydraulic fluids used for control wellheads and subsea valves.
• Chemicals used in the production and processing of hydrocarbons.
• Water-based and organic phase drilling fluids.
• Cementing, work-over, stimulation, and completion chemicals.
• Pipeline chemicals, water injection chemicals, and gas tracers.
• Biocides and oxygen scavengers.

OCNS Registration and Regulatory Authorities

The Offshore Chemical Notification Scheme (OCNS) is the regulatory framework used in the UK and the Netherlands to manage offshore chemicals. In the UK, it is regulated by the Department for Business, Energy & Industrial Strategy (BEIS), with scientific advice provided by the Centre for Environment, Fisheries and Aquaculture Science (Cefas).

The OCNS team at Cefas is responsible for registering chemicals used in offshore oil and gas applications. Suppliers must submit their HOCNF data to these authorities to gain the necessary approvals for use in the maritime waters of the UK and the Netherlands. This process ensures that every chemical used offshore has been evaluated for its potential environmental impact.

Data Requirements for HOCNF Submission

The HOCNF dossier is divided into three primary parts, requiring a combination of administrative and technical data to facilitate environmental risk assessment.

General Information on Substances and Preparations

Suppliers must provide basic identifiers, including the trade name, supplier information, and the Safety Data Sheet (SDS). This section also requires details on the intended use, discharge patterns, chemical composition, and general physical properties of the product.

Ecotoxicological Information

To assess the impact on marine life, the HOCNF requires specific environmental data:

• Bioaccumulation data: Measured by Log Pow or BCF.
• Biodegradation data: Assessing the rate of marine biodegradation.
• Aquatic toxicity data: Including tests on algae, crustaceans, fish, and sediment reworkers.

Confirmation Statement

Suppliers must confirm that all substances included in the HOCNF also comply with the relevant requirements of the REACH regulation. It is recommended that suppliers fulfill their REACH obligations before commissioning HOCNF-specific studies or completing the format with existing data.

Proregulations' HOCNF Compliance Services

Navigating offshore chemical regulations requires specialized knowledge of maritime environmental standards and inter-agency coordination. Proregulations provides end-to-end support for your OSPAR compliance needs.

• Substance Regulation Verification
  We determine whether your specific offshore chemicals are regulated under the OSPAR HOCNF framework and identify relevant national requirements.
• Compliance Strategy Development
  Our experts provide tailored strategies for data collection and submission, ensuring your products meet the safety criteria for maritime discharge.
• HOCNF Completion and Submission
  Proregulations manages the preparation of the HOCNF format and coordinates the formal submission to national authorities like Cefas.
• Regulatory Communication and Support
  We act as a bridge between chemical suppliers and national authorities, providing technical supervision and support throughout the registration process.
• Non-testing Methods Application
  Where applicable, we assist in the application of non-testing methods, such as QSAR or read-across, to fulfill data requirements efficiently.
