In order to adapt the plant for these kinds of services, new pipe connections must be created on the mooring jetties, as well as monitoring and measuring systems to allow LNG to be loaded onto small-scale methane tankers through flexible hoses suitable for very low temperatures. These tankers will then refuel large vessels moored in the port or transport the LNG to other small-scale vessels.
The adaptation of the regasification plant in Huelva for it to provide such services forms part of the CORE LNGas hive project, the aim of which is to promote LNG as a fuel, mainly for marine use, in the Iberian Peninsula. This initiative, co-financed by the European Commission, is coordinated by Enagás and led by the Spanish state company, Puertos del Estado, which manages Spain's state-owned ports.
The use of LNG as a fuel also contributes to improving air quality. LNG is an environmentally-friendly fuel as it does not release sulphur oxide (SOx) or particle matter (PM) into the atmosphere, as well as significantly reducing CO2 and nitrogen oxide (NOx) emissions, thus allowing ever more stringent environmental regulations and targets for emission reduction to be met.
