Floating LNG terminals, in terms of safety and the number of adverse security incidents, from the first day of the first floating LNG terminal operation until now, when there are now more than 20 active FSRU vessels, have not had a single incident. FSRU vessels as floating LNG terminals are used in the United States, Lithuania, Italy, United Kingdom, Malta, Turkey, Argentina, Brazil, Israel, China and other countries. 

Also, no accidents have been reported on LNG vessels carrying LNG cargo with a fleet of more than 500 LNG vessels from the very beginning of LNG transport, which is almost 60 years. 

Each FSRU vessel must meet all the requirements that any vessel in international navigation must satisfy, those prescribed by the SOLAS Convention and other international conventions accepted under the International Maritime Organization (IMO). 

The FSRU vessel must also comply with all safety requirements prescribed by the regulations of the registers of ships and by the States under which flag it sails. The FSRU vessel which will be located on the LNG receiving terminal on the Island of Krk will be under the Croatian flag.

Safety measures prescribe the construction of FSRU vessels according to strictly established international standards, construction in licensed shipyards with construction protocols prescribed by international standards, technical solutions for double hull construction and vessel tanks made of materials resistant to cryogenic temperatures, the use of airtight pipelines and atmospheric control in areas close to the cargo, installation of primary and secondary insulation of the storage area, identification of hazardous areas where special electrical equipment is installed, and removal of all flammable sources from areas where regasified LNG or boil-off gas and air may come into contact. FSRU vessels are also equipped with sophisticated leak detection technology, advanced radar equipment and a precise positioning system for berthing and mooring. 

The navigation conditions of the FSRU vessel and LNG vessels approaching to the LNG terminal, the positioning of the FSRU vessel at the LNG terminal location, the safety conditions arising from the meteorological-maritime conditions of the site, as well as the waterway by which the LNG vessels approach the LNG terminal, were covered by a Maritime Study approved by the Harbor Master's Office Rijeka. 

Also, the terms of navigation and arrival of the FSRU vessel to the LNG terminal location are also prescribed by the Circular of the Ministry of the Sea, Transport and Infrastructure on safety, security and environmental protection provisions to Croatian flagged FSRUs and non-Croatian flagged FSRUs while operating in waters under jurisdiction of the Republic of Croatia, which, among other things, prescribed the inspection of the FSRU vessel by the Croatian Register of Shipping when the FSRU vessel arrives at the location of the LNG terminal. During the inspection, the FSRU's compliance with the conditions laid down in the Circular will be verified. The compliance of the FSRU vessel with the Ministry of the Sea, Transport and Infrastructure Circular will be inspected annually.
