Energy efficiency - Eco design product tankers

Tankerska Next Generation Inc. is committed to make efficient use of energy aboard its ships with the purpose of preserving natural resources, reducing atmospheric emissions and helping to mitigate the effects of climate change.

Over recent years, firm bunker prices, slow steaming and generally low freight rates brought “eco-designs” into the global focus. Shipyards are marketing designs that potentially offer significant fuel consumption savings and speed flexibility which has generated interest and ordering activity. The exact commercial advantage of this new generation of vessels is still being scrutinized and a bit subdued due to today’s fuel oil prices however the common overall belief is the prices of oil we have been seeing the last year are unsustainable in the long run while on the other hand, the orders being placed for these sort of units are not on a short term speculative basis. As a result retro-fit solutions have been put on standby mode while there is still a growing requirement to meet various regulatory issues, including emissions (NO, SO, Carbon) and the introduction of Ballast Water Treatment (BWT) systems.

Eco ships possess various improvements on their propulsion system such as improved engines and improved larger propellers that decrease fuel consumption. New generation engines and other improvements in the propulsion system that are found on “eco ships” can provide substantial fuel consumption reduction. Also, eco ships have improved hydrodynamics such as hull optimization, energy saving devices and low friction paint to maximize the vessel’s speed at a given level of propulsion. Hydrodynamic improvements can also provide savings in fuel consumption.


TNG has been focused on developing a modern product tanker fleet


  • A product tanker is underway ~250 days in a year
  • Eco-design MR saves 5-6 tonnes of fuel per day.
  • Cost benefits (lower operating expenses estimated at 500 USD per day)
  • Intangible benefits (charterers’ preferences for a ‘greener’ vessel)
  • Higher residual value (non-ECO vessels expected drop faster in value during the next cycle downturn)
  • No environmental restriction on where vessels can trade.
