When Odfjell Drilling was preparing to add the DNV Abate P+, Emissions Reduction notation to existing Class cover, Vysus were on hand to provide the necessary expertise.
Overview
Earlier this year, the Vysus Team was delighted to learn that Odfjell Drilling had been awarded DNV Abate P+ Class.
Not only was this a key achievement for Odfjell, it was a special moment for the Vysus team who were on hand to provide the necessary experience to support the application to have the DNV Abate P+ notation added to existing Class certification.
Award of the notation requires implementation of technology and a management system which specifically addresses emission reduction, identification and assessment of abatement measures.
- Abate ready requires a management system review, baseline abatement measures, and a BAT assessment.
- Abate P requires, power plant designed to limit emissions.
- Abate P+, requires power plant designed to substantially limit emissions.
The support provided by Vysus was delivered in the form of a BAT assessment. Our task was to review and collate the evidence required to demonstrate the use of ‘best available techniques’ to reduce emissions associated with the operation of the rig fleet owned and operated by Odfjell.
The scope of the BAT assessment considered atmospheric emissions associated with design and operation of rig combustion equipment (main marine diesel engines, and mobile auxiliary diesel generators) for 4 rigs owned and operated by the company:
- Deep Sea Aberdeen
- Deep Sea Stavanger
- Deep Sea Atlantic
- Deep Sea Nordkapp
The criteria for the BAT assessment was determined by DNV Abate Class Rules which specifies the ISO 50001 standard as a framework for the Energy Management System.
Interpretation of DNV Abate criteria was supported by the application of relevant industry references: EU Hydrocarbon BREF, IPIECA / IOGP Drilling rigs Energy efficiency compendium, ISO 14064 GHG Green House Gas Quantification Standard, GHG Protocol Guidance, and the NORSOK S003 Environmental care standard.
The BAT Assessment was conducted over a three month period working in close collaboration with the Odfjell team.
What does this all mean?
The BAT assessment process demonstrates that Odfjell has established:
- A systematic approach to the identification and abatement of GHG emissions;
- An energy management system that follows the ISO 50001 standard and policy through specification, design, procurement and operation;
- Comparable emissions quantification and energy use;
- Unit specific measures to identify, to optimize or reduce energy demand;
- P+ Power system emission Abatement beyond Abate Ready and Abate (P).
Why does this matter?
There are multiple benefits to be gained from the deployment of a systematic approach to emissions reduction, evidence based demonstration of BAT and independent third-party verification:
- The implementation of a systems based EnMS and GHG emissions reduction plan supports improved legal compliance; continual improvement and reduced impact on the environment.
- The deployment of an evidence based BAT assessment demonstrates to stakeholders and interested parties that a systematic approach has been taken to assess the extent to which technical and management measures to reduce emissions can be considered BAT.
- Independent, third party verification, can be used to support decision making by regulators, investors, partners, customers and other special interest groups.
- Finally, a keen focus on energy efficiency and emissions reduction delivers reduced running costs as operations are optimised.
