Methods for booking and allocating terminal access capacities are described in the Allocation Rules.
Terminal access capacity: this refers to the maximum volume of LNG to be unloaded and regasified at a given terminal, in TWh/yr or TWh/month for a specified period, under the conditions described in a terminal access contract. A booking for this access capacity covers the following services:
Only ships listed below may be nominated by shippers to unload cargoes at the specific terminal.
Ship scheduling will then be confirmed by operations@elengy.com
These lists are based on physical characteristics and safety criteria set out in the LNG Terminal Access Contract. To ensure that these criteria are met, the Operator can inspect vessels before and during the contract period.
The registration procedure is carried out in compliance with the Operator’s specific procedure (see below)
Maximum LNG capacity of tankers registered at:
- Montoir: 266,000 cubic metres of LNG
- Fos Tonkin: 75,000 cubic metres of LNG
Under the conditions provided for in the LNG Terminal Access Contract, both Shipper and Operator agree on an estimated unloading schedule indicating the monthly amount to be unloaded. The following information should be included for each cargo to be unloaded:
Only ships registered at the terminal should be scheduled. The unloading schedule is updated every month for the following month. This involves the Shipper informing the Operator of his intended unloading dates and providing the names of the relevant LNG tankers. On the basis of their requests, the Operator informs each of the shippers their respective allocated unloading windows. Rescheduling requests for the current month may be submitted to the Operator but may not be granted.
Details of unloading schedule rules are provided in the LNG Terminal Access Contract.
Rules for scheduling and measuring the gas flow into the pipeline: the schedule of the LNG Terminal send-out is updated monthly for the following month. The definitive schedule is drawn up each day for the following day.
Rules for scheduling send-out are detailed in the LNG Terminal Access Contract. The quantities of energy sent out from the LNG Terminal are reputed to be equal to the quantities scheduled for each day.
The LNG unloaded by the Shipper must comply with the following specifications:
Parameter | Unit | Min | Max |
|---|---|---|---|
GCV (@25°C) | kWh/Nm3 | 10.70 | 12.75 |
Wobbe index | kWh/Nm3 | 13.40 | 15.65 |
RSH (as S) | mg of S/Nm3 | 6 | |
COS+H2S (as S) | mg of S/Nm3 | 5 | |
Total S | mg/Nm3 | 30 | |
Hg | ng/Nm3 | 50 | |
O2 | ppmv | 100 | |
Impurities | Gas that may be received without further treatment at the terminal entrance | ||
The Shipper is responsible for handling all customs procedures.

Natural gas is principally composed of methane (CH4) and is found in natural reserves. As a primary energy source, it offers many qualities, and is the cleanest fossil fuel.
It is appreciated for its high calorific value, ease of use, and environmentally-friendly composition.
Natural gas is odourless, but an artificial odorant is added to enable detection in the event of a leak.
When natural gas burns it does not emit dust, soot or smoke, producing only water vapour and carbon dioxide, much like human breath, which is then transformed back into oxygen by plants. It is the most energy-efficient of all fossil fuels on the market.
An explosion of natural gas can only occur if the following three factors occur simultaneously:
Every care is taken in at LNG terminals to prevent these three things occurring at the same time.

Corresponds to aggregated Shipper send-out allocations in kWh 25°C at the interface between the LSO and the TSO.
This information is provided at 7h00 LT for the preceding gas day.
Amount of gas in kWh 25°C belonged by the shippers in the tanks of the LNG terminal at the beginning of the day.
Corresponds to aggregated Shipper send-out nominations in kWh 25°C at the interface between the LSO and the TSO.

Difference between Total Firm Capacity and the amount of booked capacity.
A technology that enables a single fuel source to produce both thermal energy (heat and/or cold) and electricity at the same time.
A power station that comprises a gas turbine generator whose exhaust powers a boiler. The steam from the boiler then drives a turbo-generator.
Operator’s obligations concerning the physical characteristics of the natural gas being delivered (pressure, temperature, etc).
Liquefied Natural Gas
Facilities providing reception, storage, and regasification of liquefied natural gas (LNG) and transferring the natural gas (in its gaseous state) to the Main Network
Contract between the Operator and a Shipper, stating the reception, storage and regas conditions for LNG cargoes delivered by the Shipper to an LNG terminal.
High-pressure, large-diameter facilities linking connecting points with neighbouring networks, underground storage facilities and LNG terminals, to which are connected the regional transport networks and a number of industrial consumers and retail networks.
Responsible for operating an LNG terminal. The Operator delivers services under LNG Terminal Access Contracts signed with Shippers.
Share of the Total Firm Capacity that the terminal Operator has agreed on with a Shipper in a terminal access contract.
Corresponds to the total commercial capacity of the LNG terminal (including the already subscribed capacity), expressed as the daily average of the month, in kWh/J at 25°C.
This information is updated daily.
Terminal access capacity guaranteed under contract by the terminal Operator based on the terminal's technical characteristics, and the operating and integrity requirements of the facilities.
