“… FSRU Terminal, not only carries out its activities respecting the environment, but it is continuously looking for plant improvement following BAT philosophy…”

All the environmental aspects connected to any possible consequence on the environment around and on board the Terminal were identified and analyzed. Furthermore, OLT has arranged all the necessary and  suitable mitigation measures in order to minimize the environmental impact. This was agreed by all the competent Authorities during the permitting process and the operational phase.

The project obtained all the necessary authorizations in terms of environmental sustainability, in particular EIA (Environmental Impact Assessment), SEA (Strategic Environmental Assessment) and IEA (Integrated Environmental Authorization).The results of EIA and IEA procedures have highlighted the possibility of a real co-existence of the floating unit with the activities carried out in the geographic area where the Terminal is located.

With “IEA” Decree OLT obtained all the authorizations to go into operation since IEA includes different environmental aspects related to regasification activities, with particular reference to water and air emissions. With the EIA, on the other hand, several monitoring measures of the marine environment in the area surrounding the Terminal, including the water column and sediments, have been put in place.

The Monitoring  and Control Plan (PMC) is an essential part of IEA. It represents the Terminal’s implementation plan with reference to the environmental parameters that  should be monitored at fixed sampling rates and according to the control procedures and measures.

Furthermore, to control the potential environmental effects of the plant into the water around the Terminal, the Ministry of the Environment, with EIA procedure, prescribed that OLT adopted a well organized “ Marine Environmental Monitoring Plan” for the whole operative life of the Terminal (20 years). This plan must include the year before the Terminal installation and the year after its decommissioning. This plan, which is performed by the Interuniversity Centre of Marine Biology and Applied Ecology “G. Bacci” of Livorno, consists of 4 physical-chemical, biological and eco-toxicological monitoring campaigns per year. These campaigns focus on: water column, sediments, biological environment, measurement of underwater sounds and seabed morphology.

FSRU Terminal, not only carries out its activities respecting the environment, but it is continuously looking for plant improvement following BAT philosophy (Best Available Technologies). This is to reduces the impact that polluting substances can have on the environment even if they don’t exceed the prescribed limits.

Since 2015, OLT has been carrying out three different studies to improve the plant engineering. The first two studies concern  “air”. They have verified the feasibility of a system to reduce the NOx emissions in atmosphere and the use of nitrogen as inert gas instead of CO2 during maintenance/inspection of the LNG tanks to reduce greenhouse gas emissions (in terms of CO2). The third study was on the modification of the sewage treatment plant on board the Terminal. The aim was to eliminate the use of chlorine in the disinfection process in order to eliminate its waste in the sea water.
