Japan Marine United Delivers Fuel-Efficient 159,000 DWT Suezmax Tanker Ionic Semeli
Yokohama-headquartered shipbuilder Japan Marine United Corporation (JMU) has delivered an environmentally friendly 159,000 deadweight tonnage (DWT) Suezmax tanker to its owner.
The vessel, christened Ionic Semeli, was officially handed over on July 23 at JMU’s Tsu shipyard in Mie Prefecture. The owner is understood to be Greece-based maritime transport company Ionic Tankers.
Flying the Marshall Islands flag, the newbuild measures 274.30 meters in overall length, with a breadth of 48 meters and a depth of 23.15 meters.
Focus on Fuel Efficiency and Reduced Emissions
According to JMU, the 82,909 GT tanker is a newly developed model designed with a greater emphasis on fuel efficiency compared to earlier deliveries. The vessel’s propulsion efficiency has been enhanced using JMU’s proprietary energy-saving technologies, including:
- Super Stream Duct
- SURF-BULB
- ALV-Fin
- High-efficiency propeller
These innovations are expected to significantly lower fuel consumption and reduce harmful emissions.
Advanced Environmental Compliance
To further improve its environmental performance, the Ionic Semeli is equipped with:
- A sulfur oxide (SOx) exhaust gas cleaning system (scrubber)
- Compliance with nitrogen oxide (NOx) Tier III regulations
- Compliance with Energy Efficiency Design Index (EEDI) Phase 3 requirements
The tanker also features a ballast water treatment system and an Inventory of Hazardous Materials (IHM), ensuring alignment with the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships (HKC), which took effect on June 26, 2025.
