This report shows the main results of the engineering reports carried out by Elengy in the framework of GAINN4MOS Action. In particular, this executive summary includes the conclusions of the basic and the detailed engineering report for the adaptation of the LNG break-bulking station in Fos-Marseille to be able to deliver additional LNG volumes for trucks.

The following figure shows the location of the terminal of Elengy scope of this study:

01 Introduction

Figure 2. Operational flows in an LNG terminal. Source: Elengy

The Elengy company works in the development and operation of the Montoir-de-Bretagne methane terminals on the Atlantic coast, Fos Tonkin and Fos Cavaou on the Mediterranean coast.

An LNG terminal is an installation for regasifying liquefied natural gas (LNG) transported by sea by shippers from production areas.

1. LNG is transferred from the LNG vessel to the LNG terminal

2. LNG is received in the tank

3. LNG is transferred from the tank to the regasifier

4. The outdoor temperature makes a small portion of LNG evaporate

5. The evaporations are transformed into LNG by cooling the recondensor

6. The gas is converted from liquid to gas

7. Finally, it is counted, odorized and emitted on the natural gas network

8. It can also be transported by tanker trucks to manufacturers not connected to the grid

9. Safety device related to site equipment. During maintenance periods, the evaporation gases can no longer be recovered and are burned by the torch. It is preferable to burn methane instead of releasing it into the atmosphere (less contribution to the greenhouse effect)

Functions:

A conventional terminal has four functions:

• Receiving LNG tankers and unloading or recharging their cargo.

• Storing LNG in cryogenic tanks (-160ºC).

• Regasifying LNG according to network needs.

• Returning gas to the national transmission system.

02 General Description Of The Project

The purposes of the engineering report of the additional truck/ISO-containers loading capacity in Fos Tonkin and Fos Cavaou is aimed to study a new truck loading facility at the mentioned LNG terminals.

The main objectives of the study are as follows:

• Create an area with a capacity to received from 1 to 5 loading bays.

• Design a new entry point in the LNG terminal to avoid bottlenec-ks in the installation and prevent an excessive number of trucks inside the terminal.

• Create an impounding area of 50 m3 (HSE).

• Install a weighting brige on each bay.

• Connect LNG, BOG and utilities pipes to the existing ones.

• Build a technical room next to the loading station, where the ope-rators can work on completing the documentation.

• Automatise the operations (add a local PLC connected to the site DCS).

This report aims to present the main results of the project “Additional truck / ISO-containers loading capacity in Fos- Marseile”. The study covers both plants, Fos Tonkin and Fos Cavaou.

2.2 Time Plan

The time plan to carry out the engineering studies and the works on both, Fos Tonkin and Fos Cavou is following summarised:

1 stage | Feasability study: • July 2016 – October 2016

2 stage | Basic engineering: • November 2016 – April 2017

2.3 General Description of the Installation

The truck loading station is designed for a continuous service, 50 weeks per year and to load trucks safely within 1 hour.

As far as process fluids are concerned, it is connected to the plant :

• LNG low pressure header

• LNG recycling header

• LNG purge header

• BOG header

• Air header

• Nitrogen header

Besides pipes, valves and all traditional items (safety valves, check valves, sensors), the main pieces of equipment are :

• A weighting bridge for each bay.

• A PLC dedicated to this operation.

• A technical room for the operators and drivers.

During the feasibility study several locations on both terminals were considered:

a. On Fos Tonkin two locations were studied as the next figure shows:

03 Engineering Calculations 3.1 Piping Systems

The main piping work considered, consists of connecting the pipes to previously existing ones. The general plan for the piping works is following presented:

a. At the terminal Fos Cavaou, 150m of pipe (DN150 PN20, including insulation, control valves, safety valves, block valves and so forth) have to be erected on an new pipeway, to achieve the stated objective.

b. At the Terminal Fos Tonkin, 70 m of pipe (DN150 PN20, including insulation, control valves, safety valves, block valves and so forth) have to be erected on an new pipeway, to achieve the stated objective.

3.2 Electricity

In terms of electricity, the electrical and instrumentations works within the project consisted of the following tasks :

• Cabling all new equipment up to the existing electrical substations.

• Connecting new equipment to the plant DCS and F&G system.

• Cabling new links between the F&G system and the electrical supply of some specific items to deenergize them in case of gas detection.

• Making program modifications in the DCS and F&G system, such as declaring new inputs and outputs and modifying logics.

The following figures show the general cabling plot plan for electrical equipment and the control and command diagram.

3.3 Civil Engineering

The main works developed in the study of civil engineering are listed as follows:

• New platform.

• New roads and a new guard house. Fence from the new guard house to the loading bays.

• Building the infrastructures (piles anchored in the bed rock 15 m below ground level) for the piping and weighting bridge.

• A new technical building.

All these mentioned works are reflected in the figures shown below:

3.4 Safety

The project also includes a study of the safety issues in both plants, and it reveals the necessary implications to be developed:

• An impounding area for LNG leaks of 50 m3 is planed to be design. In thet sense, LNG leaks will be collected to this impounding area.

• The PLC which is in charge of the operation is linked to the DCS and using the same standards.

• The station will be equipped with fire and gas detectors connected to the plant F&G system.

• A system equivalent to the ship/shore one for LNG was developed. So that the truck loading ESD (which is generated by the terminal F&G system) activates the closure of the truck filling valves.

• Safety valves will prevent damages in case of over pressure.

3.5 Environmental Impact

The boill off gas (BOG) generated during a loading operation is collected via the main BOG header of the plant. It is then processed inside the main plant (compressed, recondensed and mixed with the LNG stream which is gasified and sent out on the national grid).
