About this file

This document is a Draft Scope of Work (SOW) for a five-year requirements contract to supply and deliver Liquefied Natural Gas (LNG) to Naval Station Guantanamo Bay (NSGB), Cuba. The Navy anticipates requiring approximately 4,492,530 MMBtu of LNG during the contract period from July 2025 through July 2030, with estimated annual requirements of 898,506 MMBtu to be delivered every 14-19 days. The LNG will support a natural gas-powered combined cycle power plant, with a net storage capacity of 59,921 MMBtu and an average daily consumption of 2,850 MMBtu.

The solicitation includes detailed specifications for LNG composition, delivery conditions, and operational requirements. Contractors must provide LNG tankers between 2,000-15,000 cubic meters capacity, capable of offloading at Pier C, and meeting strict maritime and safety standards. Key operational requirements include providing comprehensive documentation, complying with security protocols, performing mooring analyses, and adhering to specific unloading procedures. The contract will be a firm-fixed-price requirements contract with no minimum guaranteed quantity, and the Navy reserves the right not to make an award for any reason.

DRAFT Scope

Section A – Solicitation A.1 General Information - The item to be acquired is LNG fuel delivered to NSGB in support of a natural gas powered combined cycle power plant. The award of the LNG requirement is contingent on the future operation of the plant. Notwithstanding the future operation of this plant, the Navy expressly reserves the right not to make an award of the LNG requirement for any reason. See Section C, Description/Specifications/Statement of Work, for a description of requirements for the items to be acquired. The contractor shall be able to deliver LNG within 30 days of contract award, with the expectancy of a delivery order to be issued within 7 days of contract award via written order by the Contracting Officer.

Section B – Supplies, Services and Pricing B.1 General Requirement – Naval Station Guantanamo Bay (NSGB), Cuba anticipates requiring the delivery of an estimated 4,492,530 MMBtu of liquefied natural gas (LNG) during the 5-year term of the requirements contract. The period of delivery is anticipated to be from 11 July 2025 through 10 July 2030, FOB: Destination, pursuant to FAR 47.303-6. See Section B, Supplies or Services and Prices/costs, for expected date(s) and place(s) of delivery and acceptance, and FOB location point. The goal is to ensure that requisite quantities of LNG is delivered on a schedule to ensure that NSGB maintains storage of LNG for at least 2 weeks of usage. The following details apply:

B.2 Delivery point: FOB Destination.

B.3 Estimated schedule and quantities to be delivered - Annual LNG requirements are estimated at 898, 506 MMBtu based on the monthly usage profile below. Month to month LNG requirements may fluctuate up and down based upon base population, climate conditions, power plant outages, etc., however, the Contractor will be expected to provide delivery of LNG every 14-19 days.

B.4. Cool-Down & Commissioning - Estimated quantity and duration of stay: LNG may be required to perform cool-down and retro commissioning of the LNG facility. LNG delivery vessel will be required to remain at Pier Charlie during the offload of LNG for the retro cool down and commissioning. Maximum stay for vessel is estimated to be 5-calendar days. The Contractor has a responsibility to notify NGSB of their arrival date and time for the delivery of LNG. Arrival at Pier Charlie at an earlier data/time will not result in compensation for berthing. In addition, if the delivery vessel did not arrive at Pier Charlie at the scheduled data/time, this may cause further delay in delivery due to other activities at Pier Charlie. Hence, the Contractor is not eligible for any additional compensation than the delivery charges and the cost of LNG delivered.

Section D –Packaging and Marketing

RESERVED

Section E – Inspection and Acceptance

E.1 The Contractor shall provide a certification for each delivery including, but not limited to, the following information: Certifications will be provided to the Government before off-loading begins.

(a) LNG composition,

(b) Higher Heating Value (HHV), @ 60F in Btu/Kg or Btu/pound

(c) Lower Heating Value (LHV), @ 60F in BTU/Kg or Btu/pound

(e) Volume delivered, both in cubic meters and metric tons

E.2 While LNG loading, the Contractor will test by sampling the LNG for analysis and will also vaporize small samples of LNG to run through a gas chromatograph to confirm composition/LHV/HHV. Sampling will continue throughout the loading period of up to 8 hours. During unloading at NSGB, the Contractor will monitor delivery vessel tank levels, flow rates in the installation’s piping and levels in the installation’s LNG tanks to verify delivered volumes.

E.3 Measurement and Tests – The Contractor shall further abide by the measurement and test criteria as set forth in Attachment 2.

E.4 Quantities Delivered.

Calculation of MMBtu Quantities – The quantity of MMBtu delivered shall be calculated by the Contractor and verified by the Government. The Government may require the measurements and calculations and/or verification by an independent surveyor. If the quantity calculated by the Contractor is not confirmed by the independent surveyor, the Contractor shall be responsible for the expense incurred by the Government in hiring a surveyor.

E.5 Determination of Gross Heating Value – All component values shall be in accordance with the latest revision of GPA Standard 2145 SI (2009) - Physical Constants for Hydrocarbons & Other Compounds of Interest to the Natural Gas Industry and the latest revision of the reference standards therein. Standard reference conditions for Hi component should be 15°C & 101.325 kPa.

E.6 Determination of Volume of LNG Loaded – The LNG volume in the tanks of the LNG transport vessel(s) (LNG Tanker) before and after unloading (valves have to be closed) shall be determined by gauging on the basis of the tank gauge tables. During the period when measurement is occurring, no LNG cargo, ballast, boil-off gas, fuel oil or other cargo transfer activity will be carried out on the LNG Tanker, and the valves must be closed. Measurements shall first be made immediately before unloading commences. A second gauging shall be made immediately after unloading is completed. Accordingly, the second gauging shall be conducted upon the confirmation of shut-off of the manifold ESD valves, with transfer pumps off and allowing sufficient time for the liquid level to stabilize. Measurements prior to unloading and after unloading will be carried out based on the condition of the LNG Tanker's lines upon arrival at berth. Since significant volumes of LNG may remain in the LNG Tanker's manifold and crossover, gauging will be performed with these lines in the same condition prior to unloading and after unloading. The volume of LNG remaining in the tanks immediately after unloading of the LNG Tanker shall be subtracted from the volume immediately before loading and the resulting volume shall be taken as the volume of the LNG delivered from the terminal to the LNG Tanker.

The volume of LNG stated in cubic meters to the nearest zero point zero zero one (0.001) cubic meter, shall be determined by using the tank gauge tables and by applying the volume corrections set forth therein.

E.7 LNG Custody Transfer – The Contractor shall adhere to the principles and methods outlined in the LNG Custody Transfer Handbook by the International Group of Liquefied Natural Gas Importers.
