Recently, the H2649, the seventh very large ethane carrier (VLEC) owned by Shandong Marine Energy, a subsidiary of Shandong Marine Group, successfully returned after completing all sea trial tasks, officially transitioning from the construction phase to the delivery phase.
During the ship’s construction period, the on-site supervision team from Shandong Marine Energy closely collaborated with Jiangnan Shipbuilding (Group) Co., Ltd., achieving breakthroughs in multiple key milestones. These included achieving alignment and optical sighting within 26 days in the dock, completing painting work in the engine room area before undocking, and commencing sea trials within 80 days. For the first time, the goals of sealing all four cargo holds before sea trials and fully clearing all conventional mooring items were achieved. During the sea trials, key projects such as the remote measurement handover for ballast tank levels, liquid tank tightness tests, cargo hold tightness tests, and handover of remaining alarm points for liquid cargo were completed, laying a solid foundation for the vessel’s delivery and operation.
This vessel adopts the BrilliancE® cargo containment system, an original B-type tank independently developed by Jiangnan Shipbuilding. It offers advantages such as low evaporation rate, low maintenance costs, a simple and efficient insulation system, and low unloading residue. It can meet the transportation needs for various liquefied gases such as ethane, ethylene, and LPG. Simultaneously, it is equipped with dual-fuel main engines and a shaft generator that can use ethane as fuel. As a low-carbon ship type utilizing green alternative energy, it not only meets the Phase 4 requirements of the Energy Efficiency Design Index (EEDI) but also can reduce sulfide emissions by 99% and carbon oxide emissions by 18%, maintaining optimal economics while satisfying the most stringent emission requirements.
