CONTRACTOR: Bechtel Energy Inc.
TITLE: ISBL FEED GAS HEATER – INCORPORATION INTO TRAIN 4
The EPC Agreement between the Parties listed above is changed as follows:
BACKGROUND
Delivery of the feed gas may arrive at the Train 4 battery limit at a temperature that is less than the operating minimum defined in Attachment A, Schedule A-2 (Basis of Design). To increase the temperature of the feed gas as needed, a feed gas/ hot oil heat exchanger will be required on the feed gas line of each LNG Train upstream of the H2S Scavenger/ Hg Adsorbers (C-1104A/B).
The heat exchanger (4E-1106) procured under Change Order EC40010_SCT4010 and certain control valves procured under Change Order EC40012_SCT4012 are to be incorporated into Train 4 under this Change Order EC40021_SCT4022. The exchanger is designed to utilize hot oil (Therminol 66) from the Train’s hot oil distribution system to increase the feed gas temperature. Performance of the heat exchanger is dependent upon the available excess hot oil duty within the existing hot oil system.
CHANGE:
1.ISBL Train Feed Gas Heater (4E-1106) – Contractor shall perform all Work necessary to install and incorporate a fully functional ISBL Feed Gas Heaters 4E-1106 into Unit 11 (Acid Gas Removal Unit) of Train
4. The heater shall be installed as generally depicted in the redline mark-ups provided in Attachment 1 (Process Flow Diagrams – Redline Mark-ups) to this Change Order.
The heater shall be equipped with proper bypass and isolation for maintenance. The Work shall include, but not be limited to, piling, foundations, piping, piping fittings and components, vents, drains, control valves, isolation valves, relief valves, instrumentation, control systems, commissioning, operator and maintenance training.
2.Process Design Basis Unit 11 – Inlet Area (H2S Scavenger / Hg Adsorber) and Acid Gas Removal (RG-BL-011-PRO-DES-00001/26251-100-3DR-V04-11001)
a.Section 3.2 (Unit Description); paragraph 7 shall be modified as provided in the red-line mark-up below:

[***]
c.Section 6.9 Design Margin; Table 4: Design Margin shall be modified to insert the added Equipment into Table 4 and add clarifying note as provided in the redline mark-up below:
[***]
3.Utility Design Basis Unit 41 – Heating Medium (RG-BL-041-PRO-DES-00001/26251-100-3DR-V04-41001):
a.Section 3.2 (Unit Description); paragraph 1 shall be modified as provided in the red-line mark-up below:
[***]
b.Section 3.2 (Unit Description); paragraph 5 shall be modified as provided in the red-line mark-up below:
[***]
c.Section 5.1 (Design Case); paragraph 1 shall be modified as provided in the red-line mark-up below:
[***]
This Change Order does not change the basis of design for the feed gas battery limit conditions for which the Train 4 Facility is designed as defined in Attachment A, Schedule A-2, Section 7.4.3 Table 5: Feed Gas Battery Limit Conditions at Inlet to the Full Facility
Contractor’s Warranties provided in the Agreement apply to the Work necessary to install and incorporate the ISBL Feed Gas Heater 4E-1106 into Unit 11 (Acid Gas Removal Unit). Contractor specifically excludes any Warranties or guarantees that implementation of this ISBL Feed Gas Heater into Train 4 will have the outcome that Owner intends with respect to increasing the temperature of the feed gas to Train 4.
[***]
The Work implemented under this Change Order will result in reduction to certain margins within the existing Train design. This includes, but is not limited to:
i.Reduction in V-4101 expansion volume factor due to increased hot oil inventory
ii.Reduction in instrument air system margins due to addition of instrument air users
This Change Order excludes changes to restore margins eroded by this change. Notwithstanding the requirements of section 6.2A, section 6.4 and section 6.8(b) of the Agreement and subject to the requirements of section 6.10, should it be determined, in Contractor’s reasonable opinion, that restoration of margin becomes necessary due to the cumulative impacts of margin reductions due to Change Orders, Owner and Contractor shall execute a separate Change Order for Work to restore such margins.

TITLE: PRESSURE CONTROL VALVE AT TRAIN INLET – ENGINEERING AND PROCUREMENT
The EPC Agreement between the Parties listed above is changed as follows:
BACKGROUND
Attachment A, Schedule A-2, Section 7.4.3 defines the pressure of the feed gas at the Facility battery limit as shown in the excerpt from Table 5 (Feed Gas Battery Limit Conditions at Inlet to the Full Facility) below. This narrow range requires accurate pressure control to avoid frequent trips of the Trains.
[***]
Feed gas pressure and flow rate are controlled by the pipeline entities at the M&R skids, upstream of the battery limit to the Train 4 Facility and fluctuations and upsets (e.g. pipeline packing conditions/ train trips) can result in significant pressure variation at the LNG train inlet as well as potentially resulting in production impacts (e.g. trips, upset conditions). The Train 4 Facility does not have direct control of, or input to, the pipeline pressure and flow control systems.
Each LNG train is fitted with an HV butterfly valve for balancing flow rate of the feed gas header and minimum pressure drop to the Train. This valve has limited capabilities to perform pressure control at the Train inlet and is not intended to perform as such. Production variations or upset conditions in the Trains may affect the feed gas header conditions and affect stable operations across the Train 4 Facility.
To support the overall pressure management, pressure control valve is to be added at the LNG train inlet.
CHANGE:
1.Pressure Control Valve – [***]
This Change Order does not change the basis of design for the feed gas battery limit conditions for which the Train 4 Facility is designed as defined in Attachment A, Schedule A-2, 7.4.3 Table 5: Feed Gas Battery Limit Conditions at Inlet to the Full Facility.
Contractor’s Warranties provided in the Agreement apply to the Work necessary to procure, install and incorporate the requested globe control valve [***] Contractor specifically excludes any Warranties or guarantees that implementation of this control valve into the Train 4 Facility will have the outcome that Owner intends with respect to controlling pressure of the feed gas to the Train 4 Facility.
During the Performance Tests, the feed gas pressure to the Train shall be increased by an amount equal to the calculated pressure drop not to exceed the maximum inlet pressure per the basis of design for the feed gas battery limit conditions for which the Train 4 Facility is designed as defined in Attachment A, Schedule A-2, Section 7.4.3 Table 5: Feed Gas Battery Limit Conditions at Inlet to the Full Facility; alternatively, a mutually acceptable correction factor shall be applied to correct the pressure drop.

TITLE: FEED GAS ANALYZER
The EPC Agreement between the Parties listed above is changed as follows:
BACKGROUND
Current inlet feed gas composition is only measured by Pipeline companies with low accuracy for the heavies tail that could be present in the inlet feed gas (typically C6+ and still to be confirmed). Better knowledge of C6+ cut would help to identify operational issues particularly in Unit 17 where Heavies are subject to freeze out and impact LNG production. No means exists in the current design to analyze feed gas composition at the inlet of each train.
CHANGE:
1.Feed Gas Analyzer – [***]
This Change Order does not change the Basis of Design for the feed gas composition for which the Train 4 Facility is designed as defined in Attachment A, Schedule A-2, Section 7.4.1 Table 3: Feed Gas Composition.
The Work included under this Change Order will result in reduction to certain margins within the existing Train design. This includes, but is not limited to, a reduction in instrument air system margins due to addition of instrument air users. This Change Order excludes changes to restore margins eroded by this change. Notwithstanding the requirements of section 6.2A, section 6.4 and section 6.8(b) of the Agreement and subject to the requirements of section 6.10, should it be determined, in Contractor’s reasonable opinion, that the cumulative impacts of Change Orders result in a material reduction of those margins, then Owner and Contractor shall mutually determine to execute either a technical deviation for such reduction in margin or a separate Change Order to restore such margins.
