Dear Stakeholders,

The implementation of the IMO global Sulphur cap of 0.5% is less than a year away.  This change will result in a gigantic and historic milestone for the shipping industry.  Decisions will be made based on commercial, financial and environmental factors.  LNG as a fuel, is the best available fuel solution today and for the future.

According to the 2018 World LNG Report, authored by the International Gas Union (IGU), 2018 was the fifth consecutive year in which the global trade of Liquified Natural Gas (LNG) hit a new record.  Natural Gas accounts for almost 25% of the energy demand already.

The LNG powered fleet is constantly expanding and will be doubled by 2022.  The current LNG bunker fleet of 6 vessels will be ramped up to 14 by end of 2020.  The LNG carrier fleet enjoyed very good returns in 2018 and in anticipation of growing supply from increasing liquification capacity and global demand, LNG carrier newbuilding orders passed 60, 23% of the total LNG fleet.

2018 was the first full year for probunkers.  A year that was highlighted by the introduction of the company to the public during the premier global shipping event, Posidonia and the signing of a pioneering Joint Development Program with a leading organization, ABS.

We look forward for a productive 2019, continuing to execute our business plan and completing our financial roadshow since the positive Independent Business Review was delivered. We remain focused to our Vision, to be the premier global LNG physical bunker supplier that actively supports the future of Sustainable Shipping and Green Energy.
