The construction of the STAR Refinery Marine Terminal was carried out by ES Denizcilik, connecting the STAR Refinery, which operates at a capacity of 10 million tons of crude oil annually over approximately 2,300 acres at the PETKIM Peninsula.
ES Denizcilik worked as the EPC contractor under a contract with TSGI Müh. İnşaat Ltd. Şti (a joint venture of Tecnicas Reunidas, Saipem S.PA, GS, and Itochu).
Three pile-supported docks were constructed to facilitate the transfer of crude oil arriving by sea via tankers. The reclamation area preparation, tank terrace works, marine fill, and protection of the 1,250-meter-long slope safety works were successfully completed.
Key construction activities included:
1 million m³ of marine fill and rock protection for reclamation.
67,000 m³ of seabed dredging.
500,000 m³ of terrace and slope excavation.
28,000 meters of pile foundation installation.
14,000 jet grout installations.
4,000 rigid column installations.
1,250 meters of dyke wall construction.
800 tons of tie rod installation.
5,500 m³ of head beam construction and 3,600 m² gabion wall construction.
8,000 m³ of concrete for pipe support foundations, along with excavation, filling, and infrastructure works.
260,000 m³ of fill was made from the sea using two barges, and 67,000 m³ of seabed dredging was performed.
The project involves the construction of three pile-supported docks for vessels transporting crude oil. It consists of four main components under the Engineering, Procurement, and Construction (EPC) framework:
Dock Works: This includes the construction of two service platforms, seven loading/unloading platforms, 18 berthing dolphins, 31 mooring dolphins, and various catwalks, amounting to a total of three pile-supported docks measuring 495 m, 351 m, and 332 m.
Reclamation Works: These works involve dredging along a 1,330 m stretch of seabed, land reclamation, jet grouting, rigid columns, bored piles, and tie rod manufacturing, as well as the construction of a retaining wall and drainage works.
Site Preparation Works: This includes excavation, filling, gabion walls, concrete walls, construction of permanent roads, and drainage activities.
Slope Stability Improvement Works: These involve the arrangement of the fill area on the slope and the installation of rockfall protection barriers, covering a slope protection area of 39,159 m².
Additionally, environmental measures are included in the project to protect the endangered Posidonia Oceanica (sea grass) found in the construction area. This involves the installation of silt curtains, monitoring sediment accumulation, and measuring turbidity levels.
