· Installation of a gas engine and all auxiliary equipment in a new engine room on deck 8.
· Installation of a 30m³ LNG tank. Autonomy of the engine, 1 week.
· The energy supplied by the generator is equivalent to 2,080 GWhe / year through a natural gas consumption of approximately 400,000 m³ (n) / year.
· LNG vaporisation plant for motor supply "cold box" on deck 8 (weather cover)
· Motor totally integrated in the electrical plant of the ship, so that it can work coupled with the rest of generators of the ship.
· Possibility to make bunker by starboard or portside, depending on the direction of docking. Active and passive safety systems necessary for the operation of the new installation, according to current regulations.
Onshore LNG port infrastructure
Concerning the LNG supply system by truck (truck to ship - TTS) the infrastructure consists of a portable skid, able to connect the truck to the ship. This includes the installation of the anchors at the dock to fix the portable skid to the ground in bunkering operations.
The skid is at the port of Barcelona and is used in all the bunkering operations of Abel Matutes ship, included the first LNG bunkering of the ship carried out on the 29th January 2017.
Previous to the 1st LNG bunkering carried out on the 29th January 2017, the following two Authorisations were obtained:
· Port Authority of Barcelona Authorisation
· Spanish Maritime Authority Authorisation
The skid is equipped with:
· A rack of nitrogen bottles that allow the nitrogen sweep of the system to inertise the hoses and pipes from the port to the ship that is discharged subsequently through the ship's vent mast. This means that no natural gas or nitrogen is vented at the quay, reducing the risk of creating explosive atmospheres at the dock.
· An ESD panel which allows the communication of signals between the on-shore installation and on-board installation. This is a safety feature to deal any potential problem. For example if the ship moves and the hose is disconnected the bunkering operation can be stopped safely. The ESD panel is equipped with red or green lights which can inform the operators on shore if the operation can be carried out or not.
· Wheels which allow movement to other locations at the dock, which could be used for the operations to inertise the bunkering operations of other ships which adds flexibility to use the skid in other operations or different docking locations of the ship.
The following results were obtained since the beginning of the operation of the Pilot on the 1st June 2017, during a 17-month period up to 31st October 2018.
All the real KPI values of the ship performed better than the expected target values.
