Fleet & Assets

Port infrastructure, marine facilities, heavy equipment and full utility autonomy — the physical base behind every ERSAI project.

Overview

A complete industrial asset base, one owner.

From a unique Caspian dry dock and quayside to fabrication and piping workshops, warehouses, an office complex and a 1,700‑bed camp — ERSAI’s asset base is designed for large‑scale EPC projects in the Caspian region.

ERSAI Yard Harbor is situated in the gulf of Alexander Bekovich-Cherkassk, sheltered from southeastern and north winds. The total length of five berths is 872 m, overall quayside length exceeds 1,000 m. Water depth is 5 m (up to 6 m if needed). The harbor is protected by a breakwater creating a 350,000 sq.m basin.
