CHAPTER 5
The charter period
A Delivery
(i) The concept of delivery
5.1 The point at which the vessel is delivered into a conventional time charter is a pivotal event. The charterer retains the right of cancellation until delivery has occurred. A mobilisation fee may be payable, but daily payments of hire do not commence until delivery. Following delivery, the charterer is obliged to continue paying hire for each day, on a take or pay basis, unless it may rely upon a specific exception in the charter payment terms. The charterer loses the right to terminate after delivery for reasons which, prior to delivery, may have allowed termination. 5.2 The same concept is fundamental to the performance of an FPSO charter. The charter period does not commence, and day rates are not payable, until delivery, or the equivalent of delivery, has occurred, and rights of termination will vary according to whether the charter period has yet commenced. Notwithstanding, there is a tendency in FPSO charters to avoid using the expression ‘delivery’ to describe this pivotal event. It may be more usual to describe the process of formal acceptance and the commencement of the charter period, or commencement of day rates. It is nevertheless equally clear that this critical point is not reached until the FP Contractor has satisfied all the conditions that precede it. The reason for avoiding use of the expression ‘delivery’ may appear to be symptomatic of a general aversion in offshore oil and gas contracts to use of conventional maritime expressions. However, the true fault lies in maritime contracts themselves, as the expression ‘delivery’ is inapposite even in conventional time charters. Under English law, delivery is the voluntary transfer of possession.1 Although a vessel is described in a time charter as being ‘delivered’ when certain conditions are met, no transfer of possession occurs. The ship owner retains the possession of its vessel, continues to employ the master and crew, and following delivery into the charter provides a service in accordance with instructions given by the charterer. In the same way, under a typical FPSO time charter, which may be labelled an FPSO operating agreement or something similar, the FP Contractor remains in possession of the FPSO throughout the charter period and, using its master or Offshore Installation Manager and its crew, will provide a service in accordance with the Company’s instructions. 5.3Page 83
(ii) Acceptance
5.5 Once performance tests have been successfully completed, the Company may be required to issue an acceptance certificate. This will specify the time and date of acceptance, which will also usually be the time of commencement of the charter period. It may be the case that although performance tests have been successfully completed, or sufficiently successful for the Company to accept that full production should commence, there are nevertheless further rectification or remedial works to be performed. The acceptance certificate may specify the outstanding works, with perhaps a time period for the work to be carried out. A key point to observe here is whether the performance of the outstanding work within the agreed timetable is a condition of the Company’s acceptance, the consequence being that, if the FP Contractor fails to complete the work within the agreed timetable, the Company retains the right of termination. 5.6 The correct answer does not necessarily follow from use of the expression ‘provisional acceptance’, which carries the implication that the acceptance is conditional upon the work being performed. This expression is borrowed from EPCI contracts, whereby the provisional acceptance is the point of delivery, being the threshold of a contractor’s obligations passing from completion of the work in accordance with the specifications, to rectification of defects post-delivery in accordance with the contractual warranty terms. In EPCI contracts it is usual for the end of the defects correction period to be described as ‘final acceptance’. However, it is clear in those contracts that delivery (in the sensePage 84
(iii) Sailaway
5.9 In conventional maritime projects, for example, where a new LNG liquefaction plant requires dedicated LNG carriers, it may be expected that delivery and acceptance into the charter will take place at the same time as delivery and acceptance under the construction contract. Under a traditional LNG charter, the charterer is expected to attend gas trials and sea trials and to decide whether the vessel is acceptable in accordance with the charter terms before the ship owner is required to make the same decision under the shipbuilding contract terms. Thus, the ship owner avoids the risk of being obliged to takePage 85
(iv) Transportation
5.11 Under the FPSO charter, the responsibility to transport the vessel to the field following sailaway rests usually on the FP Contractor. It is normal for the FP Contractor to be obliged to ensure the vessel arrives at the FPSO site by an agreed deadline. As a consequence, it is not unusual for sailaway to occur notwithstanding that significant punch items7 are still to be corrected, with these items being rectified during the approach voyage or at the location. 5.12 If the construction work is being performed by way of conversion or modification to an existing vessel, it is likely the construction contractor’s responsibility (subject to rectification of defects) will cease on sailaway, and accordingly the transportation to site is performed by the FP Contractor, or by its transportation subcontractor. If the work is performed under an EPCI contract, the construction contractor may be responsible for arranging transportation to site, using its transportation subcontractor, or it may agree with the FP Contractor that the FP Contractor will take responsibility for the transportation, as a form of owner-supplied services under the EPCI contract. The point to note here is that although the transportation may in such case be performed by the FP ContractorPage 86
(v) Arrival at site
5.15 It is usual for the FP Contractor to be required to give notice of arrival at the FPSO site by a specified date. This date may be postponed if circumstances justify it under the terms of the FPSO charter. Otherwise, failure to arrive by the deadline may incur substantial liquidated damages for each day of delay. The period during which liquidated damages may accrue may be capped, in return for which the Company would require a right of cancellation of the vessel fails to arrive by the end of the relevant period. On arrival, the FPSO is required to be ready for hook up to the subsea risers, in order to receive hydrocarbons. In readiness for the arrival of the FPSO, the Company is required to bring the field into a live condition ready for flow of hydrocarbons to the vessel. If the FPSO is ready onsite, but hydrocarbons are not yet available, the FP Contractor would insist that any accrual of liquidated damages for delay should at that point cease. However, the FP Contractor would not be entitled to any remuneration thereafter, until commencement of the charter period, unless such right to remuneration is specifically included in the charter terms. This may be by an agreed rate for standby, payable in any event. However, as the Company would ordinarily not wish to commit to making any payment to the FP Contractor until the FPSO successfully passes performance tests, the Company may require the compensation for standby time occurring before start-up ofPage 87
Page 88
(vi) Commencement of acceptance tests
5.23 As mentioned in section (v), the FP Contractor will be required to commence acceptance testing by an agreed deadline, which may be specified in the calendar, or as a fixed period after the date of FPSO arrival at site. If the FP Contractor fails to start such testing, liquidated damages will accrue. Again, as with liquidated damages for late arrival at site, there will be a maximum period of imposition, in return for the Company being entitled to terminate the charter if the FPSO is not ready by that date. 5.24 The most likely reason the FP Contractor is unable to commence acceptance tests by the agreed deadline is the failure to complete outstanding work, which may have been carried over from the construction contract, and the need to comply with the requirements of the local shelf state inspector. In the scenario mentioned in paragraph 5.19, it may be the case that completion of work is so delayed that the FPSO is not ready to receive hydrocarbons by the date acceptance testing should have been commenced. ThePage 89
B Acceptance testing
(i) Acceptance test procedures
5.25 The purpose of acceptance tests under a typical FPSO charter is to verify not just that the FPSO is ready to commence operations but that all the requirements of the functional specification have been achieved. These requirements are described in , Part (v), Section H. In essence, these provide a checklist, each box of which must be ticked in order for the FPSO to be deemed acceptable for commencement of the charter. It is not usually acceptable within the charter terms for acceptance to occur if the list has been substantially complied with or if the list has been achieved in all material aspects: the requirement is that all the tests must first be successfully passed. Thus, if there are ten tests to be performed, and only nine are successful, the Company can refuse to provide the acceptance certificate. The schedule for completion of testing may be extended for weeks or perhaps months whilst efforts are made to complete successfully the outstanding tests. During this time, substantial production may occur; even offloading of cargo. However, unless the charter specifies that in such circumstances some form of acceptance should occur, or the FP Contractor should be compensated for the value of services provided during this period, no remuneration is payable. Note that under the time charter or bareboat charter terms, the charter period will not have commenced, and therefore there is no payment of day rates, even though production has commenced. The Company may be willing to compensate the O&M contractor for the services it provides during this period. However, strictly speaking it would not be obliged to do so, as the O&M services would usually begin only once acceptance has occurred. 5.26 If the FP Contractor considers there are aspects of the functional specification which, although important, need not be fully tested prior to completion of acceptance testing, this should be clearly specified in the charter as an obligation to be performed after acceptance. For example, there may be gas injection equipment which is required for the later stages of production, but is not essential to be fully functioning prior to acceptance. Parties may consider whether offloading tests should be included as part of acceptance. It is important to note here also that the threshold of tests that must be performed before acceptance, and the level of performance to be achieved, should bePage 90

(ii) Provisional acceptance/interim production
5.31 We mentioned earlier that acceptance may be described as being provisional, which leaves open the question of whether the Company retains the right to terminate the charter if outstanding works are not completed within a specified period. It may also be described as being conditional on the successful completion of specific tests or rectification of Category A defects. 5.32 The FP Contractor, who at this time may have received no remuneration for the work performed in preparing the vessel for production from the field, will want the charter period to commence as soon as possible, in order that the payment of day rates may commence. Therefore, the FP Contractor may continue with its testing, making adjustments and modifications in the hope of achieving the required level of performance. During this time, production continues. The question that often arises is whether, given that during the continued attempts to pass performance tests, the FP Contractor is producing oil or gas for the benefit of the Company, may the FP Contractor receive at least some remuneration for the benefit provided? This is sometimes described under English law as the right to be paid according to the value received, or quantum meruit.18 The difficulty with this argument, if used for underperformance failing to achieve acceptance, is that remuneration by way of quantum meruit applies only where the contract does not provide a payment mechanism relating to the circumstances covered. Under a typical FPSO charter, the circumstances are covered; it would provide that the FP Contractor is not entitled to payment until acceptance is achieved. Where there is a separate O&M agreement, with its own remuneration provisions, the FP Contractor may alternatively argue that it is nevertheless entitled to remuneration for providing a service under that agreement, even though no right to payment has accrued under the charter. However, as mentioned in paragraph 5.25, although the Company may be willing voluntarily to pay for the services of the O&M contractor during this testing period, it is not contractually obliged to do so, as the payment regime under the O&M contract will usually commence only once the charter period commences, following acceptance. 5.33 Another aspect of the same conundrum is that the FP Contractor is not obliged to continue production prior to acceptance; it does so in the hope of passing the acceptance tests, but may, if it prefers, shut down production while it endeavours to resolvePage 92
(iii) Reservoir characteristics
5.34 When the conditions for acceptance have not been met, the FP Contractor will inevitably question whether the reason is due to the characteristics of the hydrocarbons being extracted, or the performance of the reservoir and related structures. If gas is being processed, its composition may include a greater proportion of condensate than anticipated. It may be said the oil is too waxy, or gassy, or wet, or otherwise fails to achieve the specification in the basis of design. The Company’s position may be that the hydrocarbons are within acceptable parameters, but in any event any deviation is not the cause, or not the only cause, of the FP Contractor’s underperformance. The parties may agree that the quality of hydrocarbons and the reason for underperformance may be referred for determination by technical analysts – although it may be a considerable time before they are able to achieve reliable results, and even then, it may not be easy to determine whether out-of-specification hydrocarbons is the reason for the underperformance. Thus, the dispute may be unresolved for a significant time, during which there may be a period of interim production, as referred to earlier, or a period of shutdown, with the Company threatening to exercise its rights of termination. The particular difficulty faced by the FP Contractor in these circumstances is that even if it is able to establish that the hydrocarbons are outside the specification, the fact remains that the conditions of acceptance have not been met. The charter may provide that the FP Contractor is entitled to a variation order for the consequences of the out-of-specification hydrocarbons, but the burden would rest on the FP Contractor to demonstrate what that variation should be. The FP Contractor may face the further difficulty that although the specification has been provided for in the basis of design, it does not necessarily follow that the Company has warranted the hydrocarbon characteristics.

The charter period
5.35 The agreed charter period dictates the minimum time during which the Company charterer is obliged to continue paying hire or day rate. Consistent with the concept of take or pay, the Company is obliged to continue paying the day rate throughout the charter period even if, for whatever reason, it may no longer have need for the vessel being chartered. The most obvious reason would be the reservoir has been depleted more quickly than expected, or is found to be uneconomic to produce. With this possibility in mind, the Company may wish to commit only to an initial charter period, which is likely to be less than the full period for which the FPSO is needed, with a view to extending that period, if necessary, in due course. Extending the charter period is covered in more detail in concerning payment of day rate.
5.36 If the Company wishes to cease operations before the initial period has expired, or before the end of any agreed extension period, the FP Contractor would be entitled to refuse. The question then arises whether the FP Contractor would be entitled to keep the FPSO on station and claim day rate for the unexpired period of the charter, even though no contractual performance is required. In legal terms, even though the Company’s wish to terminate the charter period may be a repudiatory breach, the question is whether the FP Contractor is obliged to accept that breach and bring the contract to an end and claim its loss, or may it affirm the contract, and insist it continues until the charter period expires. The answer is found in equivalent maritime law concerning bareboat chartering of a vessel.19
5.37 If an FP Contractor accepts the Company’s repudiation of an FPSO charter, its loss would comprise the unpaid profit on day rate for the unexpired period, including the opportunity to receive payment of bonuses, for a period which may be many years. However, the FP Contractor would have a duty to mitigate its loss, taking into account the possibility of redeploying the FPSO before the date when the original charter period would have expired. This would lead to a complicated and often speculative calculation concerning the prospects for redeployment. To avoid such complications and protracted disputes, the charter will often grant to the Company a right of termination without cause, or ‘for convenience’, in return for payment of an agreed termination fee. The fee to be paid would vary according to when the termination occurs and would also require a degree of speculation.
5.38 If the FP Contractor successfully negotiates into the contract terms a generous fee that the Company is obliged to pay on termination for convenience, it would be unsurprising if the Company wishing to terminate before the expiry of the charter period would first consider whether it has alternative remedies. For example, the contract would usually allow the Company to terminate in the event of FP Contractor’s material breach or continuing underperformance.20 It may be thought that unless the FP Contractor is clearly Page 93
Page 94
D Redelivery
5.39 In the same way as the act of delivery usually represents commencement of a charter period for a conventional vessel, the act of redelivery usually represents the end of that period. Thus, the obligation to pay hire or day rate commences on delivery and continues until redelivery. There may be no actual redelivery, in the sense of transfer of possession from the Company to the FP Contractor, under a typical time charter, as the vessel at all times remains in the possession of the FP Contractor. The parties are free to agree what event marks the exact moment of redelivery, which is usually when the vessel reaches an agreed location or range. 5.40 If the charter is in the form of a lease, or bareboat charter, there may be a true redelivery in the sense of possession being handed back to the FP Contractor, but even here, conditions may be attached to the point where the FP Contractor is obliged to accept redelivery, for example following any repair work to enable the vessel to be redelivered in like good order and condition as when first delivered. 5.41 These same principles apply to the end of a charter period for an FPSO, but the conditions attached to redelivery may be more extensive; for example, expiry of a notice period and payment of the day rate until the Company has finally shut in production and has removed the cargo from the FPSO. 5.42 It is important to note that although redelivery may signify the cessation of the Company’s obligation to pay day rate, it does not signify the end of the FP Contractor’s contractual obligations. In particular, the FP Contractor may be required to remove the FPSO and all its ancillary equipment from the location, at all times in compliance with the safety and environmental regulations. The Company may require the FPSO and crew to remain onsite for some considerable time after cessation of production to allow the FPSO facilities to play their part in the preparation of the subsea wells, flowlines and risers for abandonment (removal).22 5.43 It is usual for performance of these post-redelivery obligations to be remunerated by way of a demobilisation fee, payable once all requirements of removal of the FPSO have been satisfied. This fee is normally a lump sum to cover whatever costs the FP Contractor may incur. 5.44 The relationship between redelivery and termination under a typical FPSO charter is often not set out with clarity, the assumption being that redelivery occurs on termination. However, as explained earlier, the requirements for redelivery may not have been achieved at the date of termination, and the FP Contractor’s obligations do not end onPage 95
