The availability record for unplanned outages only, over the same period, is:
To further improve our availability to customers, CATS operates a non-intrusive inspection philosophy as part of a comprehensive Integrity Management Scheme.
We aspire to use this work to justify increasing the duration between shutdowns for visual inspection while continuing to maintain the plant to exacting standards and meeting our legal and regulatory obligations in this respect.
The CATS pipeline has six subsea tees. Entry to the CATS system can be offered via a flanged entry point on one of the six subsea tees on the pipeline, at the CATS riser platform, or via one of the existing CATS hubs, subject to agreement with the hub owner.

The CATS Standard Terms set indicative commercial terms on which CATS Parties are prepared to negotiate with the gas owners (shippers) for CATS to transport and process the gas – subject to approval from the respective boards of directors.
It is not intended to be an offer capable of acceptance or to create any legally binding arrangement or obligation.
Matters remain on a subject-to-contract basis unless and until legally binding agreements are executed.
Any discussions on these non-binding terms will be on the understanding that any negotiations and eventual agreement will need to satisfy all regulatory and legal requirements.
When agreed, these commercial terms will be embodied in a fully termed transportation and processing agreement.
CATS Parties may revise, update or replace any or all of the standard terms from time to time.
Additionally, the CATS System offers a number of key benefits to potential customers, including:
- Excellent availability (average of 99.3% over the last five years)
- Customer focus – the system offers attractive and competitive services to customers’ fields
- Access to low NTS Entry Charge – attractive differential NTS charge between Teesside and St Fergus
- Contaminants removal service available
- Excellent safety and environmental record, including British Safety Council 5 Star Health and Safety Awards (seven years running) and the Tees Valley Business Environmental Award (2004)
The CATS Parties unanimously support the Infrastructure Code of Practice and the Commercial Code of Conduct and are committed to supporting the development of fields in the North Sea.
Prospective Shippers, who are interested in receiving terms and conditions specific to their development, should contact the CATS Commercial Team at: info@kellasmidstream.com
This application should provide information regarding the services requested, gas profiles, gas specification and amount of capacity required.
Following receipt of applications, providing the application is a bona fide request for provision of terms for transportation and processing services, and providing there is sufficient relevant information supplied, we would anticipate responding within 10 working days.
We welcome the opportunity to speak with all prospective customers.
Standard terms – transportation & processing
The CATS Standard Transportation and Processing Agreement is based around two key components:
(i) Section I - Form of Agreement (Specific Terms)
Each new field is different and sometimes requires an individual commercial solution depending on the nature of service required. We have grouped together the key commercial terms, that may vary from field to field, into a simple streamlined document that can be negotiated and drafted simply and quickly.
(ii) Section II - Conditions of Contract (General Terms)
The CATS System is a large integrated gas transportation and processing system which offers its transportation and/or processing services to a number of Shippers. Based on our experience and our varying commitments, this agreement details the general terms, conditions and procedures, applicable to all shippers, that have been developed over time to ensure the safe, efficient and sustainable operation and management of the CATS System. A copy of the CATS Standard Section II – Conditions of Contract for the Transportation and Processing Agreement can be downloaded below.

Standard terms – processing
Indicative Terms and Conditions for the processing of gas by CATS are available by contacting Kellas Midstream Limited.
Standard terms – small fields
The CATS Partners have developed indicative Small Fields terms, including no send or pay and a flexible capacity booking mechanism to enable prospective customers with small gas volumes to access the UK gas market through the CATS System.
These terms have been designed specifically to meet the needs of new developments with total reserves of less than 50 mmboe and gas reserves of less than 10 mmboe. They are available for new customers seeking a transportation and processing service and entering CATS via any of the CATS Ts, the CATS Riser Platform or via an existing hub platform (subject to the necessary agreements with the appropriate field owners).
