Individual logistics services

This service includes the right to use the facilities necessary for the unloading of LNG from a vessel at a regasification plant.

It is provided at all our terminals. However, before unloading a methane tanker for the first time, Enagás will request a report assessing the tanker’s compatibility with the terminal. The tanker also requires vetting, a safety inspection certificate provided by an officially approved and internationally recognised company.

This service includes the right to use the facilities necessary for the regasification of LNG from the virtual balance tank (TVB) at regasification terminals.

It is available at all our LNG terminals. Liquefied natural gas, which is unloaded and stored in tanks at the terminals, is then vaporised to return it to its gaseous state and then fed into the transmission network.

This service includes the right to use the facilities necessary for the storage of LNG in the Virtual Balancing Tank (TVB) at regasification terminals.

It is available at all our LNG terminals and at the other plants of the Spanish gas system. It is contracted as a delocalised service, i.e. LNG is stored in the general system, not at a specific terminal. This is what is known as the Virtual Balancing Tank (TVB).

This service includes the right to use the facilities necessary for the loading of LNG into trucks at a regasification plant.

Enagás has been providing this service since it commenced operations in 1969. All our LNG terminals have truck loaders with cutting-edge technology to ensure agile, reliable and safe loading.

Trucks must arrive at our terminals with optimum pressure and temperature conditions. When loading is complete, the trucks move from the Enagás terminal to satellite distribution plants. From there, the gas will be supplied to certain areas through gas distribution pipelines or to facilities where supply from the pipeline network is not possible.

This service includes the right to use the facilities necessary for the loading of LNG onto a vessel at a regasification plant.

All our terminals are equipped to provide this service. We offer reloading services for both small- and large-scale vessels and have made technical adjustments to the berths to facilitate the reloading of all tanker types and to eliminate boil off in these operations. We have also invested in increasing reloading flow rates to current levels.

At Enagás, the safety of operations and the protection of the environment are paramount. Therefore, before undertaking the first reloading of a methane vessel, be it small- or large-scale, Enagás will request a report assessing the tanker’s compatibility with the terminal. The tanker also requires vetting, a safety inspection certificate provided by an officially approved and internationally recognised company.

This service includes the right to use the facilities necessary for the transfer of LNG from one vessel to another, a process also known as “Transhipment”.

Different technologies are used to perform this type of operation and, at Enagás, we work to optimise the use of our infrastructure through efficient technology. Currently, our LNG terminal in Cartagena provides this service under the Transhipment Berth-to-Berth modality and is preparing to offer the Transhipment Ship-to-Ship service as well.

In all services involving methane vessels, Enagás will request a report assessing the tanker’s compatibility with the plant before operations can commence. The tanker also requires vetting, a safety inspection certificate provided by an officially approved and internationally recognised company.

With the aim of carrying out all operations in conditions of maximum safety, we offer a vetting service to all our customers. This service consists of providing vetting acceptance certificates for LNG tankers.

The certificates allow Enagás to verify that the tankers meet the requirements laid down in international regulations and the standards and criteria used by LNG terminal operators, and the service includes ongoing reviews.

The vetting service is available for all types of tankers, including small-scale, large-scale and large Qmax tankers, and includes the following checks:

  • Vetting assessment: inspection of documents to ensure the safety of tankers and compliance with LNG maritime transport regulations, including, among others: the Ship Inspection Report Programme (SIRE) and OCIMF’s Vessel Inspection Questionnaires for Oil Tankers, Combination Carriers, Shuttle Tankers, Chemical Tankers and Gas Tankers (VIQ).
  • Physical tanker inspection: on-board inspection, when it is deemed necessary, to obtain approval for tanker access to facilities.

Enagás has developed its own set of standards to ensure the highest levels of safety and efficiency in LNG tanker operations worldwide

 

This service includes the right to use the facilities necessary for purging the inert gas out of the tanker (gassing up) so that it can receive LNG from liquefaction or regasification terminals, following the appropriate safety standards in each case.

The cooling down operation consists of reloading small quantities of LNG to the vessel to bring the inside of the methane tanker to temperatures nearing -160ºC and to the optimum pressure to carry out reloading or unloading operations.

All our LNG terminals provide a cooling down service. In addition, we check variables such as flow, pressure and temperature to ensure the success of the operation.

The volume of cargo associated with the cooling-down service shall not exceed the tanker’s fill level.

Customers wishing to request the gassing-up service should be aware that the vessel must arrive at the terminal with an inert gas atmosphere.

In all services involving methane tankers, Enagás will request a report assessing the tanker’s compatibility with the plant before operations can commence. The tanker also requires vetting, a safety inspection certificate provided by an officially approved and internationally recognised company.
