2. Basic Design of the Terminal
3. Procurement activities for technological equipment
4. Detailed Design of the Terminal
5. Construction of the Terminal
6. Commissioning and performance testing

Project Description:

The construction of the jetty took place north of the Kiaules Nugara Island in the port of Klaipeda, Lithuania. The jetty consists of 11 platform – the Service Platform, 6 Mooring Dolphins, 3 Berthing Dolphins and the High Pressure Gas Platform where the gas unloading operation will take place. Tubular steel piles were used as foundations for the platform and driven with pile driving equipment. A combination of precast concrete structures and in-situ monolithic concrete structures was used for the execution of the platform load bearing elements. The precast concrete structure were produced by JSC BGMS. The base height of the platforms is +6.50 above sea level. All works were executed on a marine environment.

Two building where built to contain the control, firefighting and intruder detection systems. Mooring Dolphins are equipment with mooring release hooks, capstans and associated equipment and hardware. Berthing dolphins are equipped with fenders, two berthing dolphins are equipped with monitor towers, one of which is the base for the gangway access system.

The High Pressure Gas Platform accommodates facilities required for transfer of gas from the FSRU as well as metallic structures for the berthing of service vessels. Such structures were also constructed on the Service platform to berth service ships. The Service platform accommodates firefighting equipment and electrical equipment including diesel electric generators, fuel tanks, transformations and main switchboards.

Budget: 32 900 000 €
