“In the event that the CATS parties have contracted the use of the CATS Transportation Facilities for Non-Capacity Gas, the CATS Operator shall promptly, subject to the provisions of clause 24.4, give [TGTL] a notice containing the following information: (i) the field from which such Non-Capacity Gas shall be produced and the facilities from which such Non-Capacity Gas will be metered and delivered to the CATS Transportation Facilities; (ii) the proposed point of delivery of such Non-Capacity Gas into the CATS Transportation Facilities; (iii) the proposed point at which such Non-Capacity Gas is to be re-delivered from the CATS Transportation Facilities; (iv) the date on which the transportation of such Non-Capacity Gas is proposed to commence; (v) the estimated date on which the transportation of such NonCapacity Gas is proposed to terminate; (vi) the specification in a format to be agreed of such NonCapacity Gas at the point referred to in paragraph (ii) above together with a bona fide estimate of the composition of such Non-Capacity Gas during the proposed period of transportation of such Non-Capacity Gas; (vii) the maximum rate of delivery of Non-Capacity Gas at such point during the proposed period of transportation; and (viii) the bona fide but non-binding estimate of the aggregate quantity and composition of Non-Capacity Gas (including NonCapacity Gas under the contract the subject of the notice under this Clause 4.6(a)) to be delivered to the CATS Transportation Facilities for each Month of the current and each of the next 5 Contract Years and for each Quarter during the remaining term of this Agreement.”
“No less frequently than Quarterly, the CATS Operator shall, subject to the provisions of Clause 24.4, give [TGTL] a notice containing the following information: (i) any changes in the information previously provided pursuant to Clause 4.6(a); and (ii) the CATS Capacity for the ensuing Contract Year.”
“The foregoing information is provided for operational and planning purposes only and, so long as the information has been provided in good faith, the CATS Parties and the CATS Operator shall not be liable for the accuracy of any such information, nor shall any such information vary the respective rights and obligations of the Parties under this Agreement.”
“The contribution to the Static Volume for each CATS Field will be as follows: (a) where the total of the Notified Rates for all Producing Designated Fields does not exceed the Capacity Reservation Rate, the product of (i) a fraction, the numerator of which is that CATS Field’s Booked Capacity and the denominator of which is the total of the Booked Capacities for all CATS Fields, times (ii) Static Volume; (b) where the total of the Notified Rates for all Producing Designated Fields exceeds the Capacity Reservation Rate, for each Producing Designated Field: (CRR / CRR + Total Booked Capacity for all Non-Designated Fields) * (Producing Designated Field’s Notified Rate / Total Notified Rate for all Producing Designated Fields) * (the Static Volume)”

“the maximum rate (expressed in Cubic Metres) of [name of field] Gas per Day as varied from time to time in accordance with these Heads of Agreement … at which the [third party shipper] wishes to reserve capacity in the CTF.”
“149. … For that period, towards the end of the duration of the CRTA, the parties agreed to substitute what may broadly be called a cost share regime for the earlier tariff regime. Under that cost share regime, the current costs (i.e. those relating to the Contract Years of the Capacity Fee regime) were to be divided up. Under such a cost share regime, it could be expected that those current costs would be divided amongst those actively using the facility during the period in which those costs were incurred and in proportion to their usage of the facility, and not on the basis of what they might have been shipping many years, and in some cases decades, earlier.”
“151. … The CRR was defined in the CRTA as a rate of 8,334,900 cu m/d ‘as the same may be adjusted in accordance with this Agreement’. By clause 21.1 of the CRTA TGTL had the right, on not less than two years' notice, to reduce, but not thereafter to increase, the CRR, provided that such reduction should not be effective before1 October 2008 . Under this clause, TGTL thus had the right to reduce the CRR, apparently on multiple occasions. It did, as a matter of fact, exercise that right by reducing the CRR to 6,515,000 cu m/d with effect from1 October 2017 by a letter dated28 September 2015 . The CRR to be used in the formula was the up to date CRR, as amended pursuant to clause 21.1. I consider that the fact that this aspect of the equation was up to date in this sense, lends support to the idea that the parties intended the other aspect of the fraction, and the other aspect of the denominator, also to be up to date.”
“154. The above analysis of the CRTA is further supported by the way in which the relevant concepts were expressed through the process of amendment. The phrase 'maximum rates of delivery of Non-Capacity Gas notified by the CATS Operator pursuant to clause 4.6(a)(vii)' was, in the unamended CRTA, adopted as the definition of 'Booked Capacities'. The contractual purpose of the phrase 'Booked Capacities' was in determining matters of allocation, under Schedule XIII. Upon amendment in 1998, Schedule XIII was deleted, the allocation provisions being thereafter found in the TAA, and the term 'Booked Capacity' was defined in the TAA as 'the aggregate of all the Firm Shipper Capacities'. The 'Firm Shipper Capacities' are the DRCRs for each shipper, as set out in Schedule VII to the TAA, as updated from time to time in accordance with clause 10.8 (which included a provision for the amendment of Schedule VII no more frequently than quarterly). Of course, the definitions in Schedule XIII and in the TAA never co-existed, and cannot properly be used to cross-define terms. Nevertheless, it is a reasonable inference, having regard to the 47. whole contractual scheme, that what was being referred to as 'Booked Capacity' was never intended to change, and that that phrase, like 'CATS Capacity' was a varying, updated, figure.”
“158. In my judgment the argument is unconvincing. In providing that what should be notified was the 'maximum rate of delivery' during the proposed period of transportation under a newly-entered into TPA, the parties were not seeking to identify a figure which would be the highest at any point during that period, which would then be the figure set in stone for the purposes of the CATS Capacity, absent a variation of the TPA. Instead, I consider that what was being sought was the relevant DRCR figure. In this regard, it is significant that in the TPAs, the DRCR was regularly referred to as the 'maximum rate' of reserved capacity. While I was not shown any transportation agreement pre-dating the conclusion of the CRTA in 1990, and thus was not shown any definition of a DRCR in terms of a 'maximum rate' which formed part of the background matrix to the contract as initially concluded, this usage was contained in almost all the TPAs, including the very first which dates from January 1991. I considered that it was very probable that in entering into the CRTA the parties had had such a way of referring to a DRCR in mind. In any event this type of definition of DRCRs was used in a number of other TPAs dating from the period between 1991 and 1998, and these can, I consider, be taken into account as part of the background known or taken to be known to the parties, when construing the CRTA as amended in 1998. 159. Accordingly, I consider that what clause 4.6(a)(vii) was requiring should be notified was the DRCR figure specified in the TPA. … 160. Furthermore, and consistently with the above, I consider that it is plain that the parties intended that the figure notified under 4.6(a)(vii) should be kept up to date, and that this was the purpose of the reference to 'subject to any changes notified pursuant to clause 4.6(b)(i)'. Under the unamended CRTA, the information notified under clause 4.6(a) was to be updated no less frequently than quarterly. That would have allowed the updating of the figures for the maximum rate of delivery of Non-Capacity Gas. In this way the up to date DRCR figure would be available for the calculation of CATS Capacity, consistently with the overall intention of the CRTA for this to be an up to date figure, as discussed in the previous section of this judgment.”

“the Capacity Users shall in aggregate be entitled to a portion of the Available Capacity equal to the proportion which the Capacity Reservation Rate bears to the CATS Capacity.”
“The Right of Substitution may only be exercised by [TGTL] or the CATS Parties to the extent that: (i) there is spare capacity in the Capacity Reservation, as determined by [TGTL] (in the case of Substitution In); (ii) there is spare capacity in the CATS Capacity (other than the Capacity Reservation), as determined by the CATS Operator (in the case of Substitution Out); and (iii) in the reasonable opinion of the CATS Operator, the commingled stream in the CATS Transportation Facilities resulting from the exercise of the Right of Substitution can be transported, processed and redelivered in compliance with the relevant redelivery specifications according to the standards of a Reasonable and Prudent Operator and with no material adverse effect on any other CATS user.”
“Having regard to each of the seven schedules, I consider that they do constitute update notices in accordance with clause 4.6(b) and that a reasonable observer would interpret them in that way. … In my judgment, the schedules clearly provide updates of the information which is properly (on the view I have set out above) to be provided pursuant to clause 4.6(a)(vii). I consider that a reasonable observer would understand that the information originally provided under clause 4.6(a) was intended to be amended by these detailed schedules.”
