The association suggested at a news conference in Rijeka on Sunday that the terminal be built near the offshore platforms Ivana 1 and Ivana 2.
The news conference was also attended by the secretary-general of the European Federation of Green Parties, Arnold Cassola, who was on a visit to Eko Kvarner.
Eko Kvarner president Vjeran Pirsic said that security standards would be met if the terminal was built near the two platforms because they were located more than eight kilometres from the nearest settlement.
The platforms are connected with the mainland by a gas pipeline which could be used for
the transport of liquefied gas from tankers, Pirsic said.
Eko Kvarner is satisfied with the government's decision to set up a task force to investigate the advantages of some locations for the LNG terminal, he added.
Cassola, who is a candidate on Romano Prodi's list L'Unione Romana for the Italian diaspora at parliamentary elections, said the party believed that Croatia should draw up necessary studies and meet European transparency standards before making a decision on any dangerous project.
He added that it was not good to launch new projects related to hazardous cargo, such as gas and oil, in the Adriatic due to possible threats to tourism.
