GTT has achieved a major milestone with its innovative Recycool™ system, which has successfully passed all performance validations during integration and operation on ten newly built containerships at Samsung Heavy Industries’ (SHI) shipyard. This achievement underscores GTT’s commitment to advancing LNG-fueled vessel technology by optimizing boil-off gas (BOG) management.
Recycool™: A Game-Changer for LNG-Fueled Vessels
Recycool™ is a cutting-edge system designed to efficiently recondense boil-off gas, reducing fuel consumption, minimizing the vessel’s carbon footprint, and ensuring safe operations. The system is particularly suited for LNG-fueled vessels equipped with MAN Energy Solutions’ MEGI propulsion system, which requires precise BOG management to maintain efficiency.
The Recycool™ system offers several key advantages:
- Fuel Savings & Carbon Reduction: By reliquefying excess BOG, the system prevents energy waste, reducing emissions and improving overall fuel efficiency.
- Compact and Versatile Design: The system can be installed as a standalone solution or integrated into the high-pressure fuel pump skid, providing shipowners with flexible deployment options.
- Reliability & Safety: Utilizing passive components without rotating machinery, Recycool™ ensures smooth and safe operations with minimal maintenance.
Addressing a Key Challenge in LNG Bunkering
Managing boil-off gas is a critical challenge for LNG-fueled vessels. MEGI engines, known for their high energy efficiency and low methane slip, require high-pressure compressors to handle BOG efficiently. Traditional low-pressure compressors are less effective, often leading to wasted energy and suboptimal tank pressure control.
Recycool™ tackles this issue by harnessing unused cold energy from the LNG vaporizer to reliquefy excess BOG. This innovative cold recovery process significantly improves vessel efficiency and reduces overall emissions.
Proven Performance and Industry Impact
The successful commissioning of all ten Recycool™ systems confirms GTT’s ability to deliver high-performance solutions for the LNG fuel market. The system’s performance has met expectations, reinforcing its role as a key enabler of sustainable shipping.
Advantages of Recycool™
- Simple & Compact: Easy integration with minimal space requirements.
- Cost-Effective: Low capital and operational expenditure (CAPEX and OPEX).
- Consistent High Performance: Maintains efficiency across a wide range of BOG temperatures.
- Environmentally Friendly: Helps vessels comply with stringent emissions regulations.
With the growing adoption of LNG as a marine fuel, technologies like Recycool™ play a crucial role in enhancing operational efficiency and environmental compliance. GTT remains committed to supporting industry stakeholders by providing innovative solutions for sustainable shipping.
