Nakilat has been shortlisted for the CWC LNG Technological Innovation Award at the 17th World LNG Summit in Barcelona this year. Can you tell us more about the latest green technologies that Nakilat has adopted onboard and how these impact operational efficiency?
As a global leader in LNG transportation, Nakilat has adopted the latest green technologies on-board to enhance operational efficiency and operate in an environmentally-responsible manner. To this effect, Nakilat has effectively capitalized on its vast expertise in handling gas carriers and completed the world’s first main engine gas injection (MEGI) retrofit for a Q-Max LNG vessel to run on LNG as an alternative fuel. The modified vessel has the world’s first low-speed marine diesel engine that can utilize forced LNG boil-off gas and HFO, depending on the requirements of the voyage.
The MEGI retrofit conversion project is the first of its kind, and out measures similar system installations on new buildings due to the complexities involved in integrating this new system with existing ones on-board the vessel. Unlike most new buildings, the technology utilizes liquid-LNG directly from the cargo tank, which has also proven to run reliably from re-liquefaction condensate return, giving further flexibility in operation. The system involves extracting liquid-LNG from the vessel’s cargo tank, storing it in fuel supply skids (FGSS) and pressurizing it to power the engines. This is also the first ever ME-GI conversion involving a twin-engine configuration along with the associated systems, piping and safety shut-down systems allowing for redundant operations.
The converted vessel is able to operate with maximum flexibility in a safe and sustainable manner, enabling the vessel’s engines to meet current and future emissions standards set by the International Maritime Organization (IMO).
What are the environmental benefits of the new technologies?
The use of MEGI allows a cleaner fuel technology with a significant reduction in environmental emissions, cleaner burning engines with potential to increase mean time between maintenance, provide flexibility of fuel supply to react to market changes and reduced bunkering activities which in turn will offer operations and marine risk reduction.
Not only will this pilot MEGI retrofit result in greatly reduced emissions but also, it will allow the converted vessel to operate with maximum flexibility in a safe and sustainable manner, enabling the vessel’s engines to meet current and future emissions standards set by the International Maritime Organization (IMO).
How will the International Maritime Organization’s recently announced new regulations on sulfur emissions impact the future of LNG as a marine fuel?
Green shipping is the future of the maritime industry as we see it and LNG as a fuel can represent a significant part of that future. It has the ability to reduce Sulphur emissions by up to 95%, NOx emissions by 80% and cargo content by up to 25%. It has cost benefits over distillate fuels and removes the contaminants at source when compared with the use of scrubbing technology. LNG as marine fuel is developing a lot of interest as a sustainable alternative and compliant fuel to meet current and future emissions regulations.
What does being shortlisted for the CWC LNG Technological Innovation Award mean for Nakilat?
Nakilat is honoured to be shortlisted for this prestigious global award that recognizes us as one of the leading innovative companies in the LNG industry. The successful completion of the MEGI project is a milestone in Qatar’s standing as a reliable provider of clean energy in a safe and environmentally-sensitive manner, and highlights Nakilat’s proactive approach in adopting the latest technological advancements on its vessels towards the sustainable development of the maritime industry, in line with its vision to be a global leader and provider of choice for energy transportation and maritime services.
Nakilat are nominated for the CWC LNG Technological Innovation Award. The winner will be announced at the CWC World LNG Summit on Tuesday 13 December 2016. For more information on the CWC LNG Awards please click here.
