LNG delivers strong returns on investment across different vessel types trading internationally.

LNG is the only alternative to traditional marine fuel oils which is commercially viable for deep-sea shipping.

Independent modelling of the investment case for LNG-fuelled vessels across a variety of different vessel types and trade routes using publicly available data on CAPEX shows that LNG provides a compelling business case for ship owners when compared to conventional marine fuels.

Analysis clearly shows that LNG as a marine fuel delivers the best return on investment on a net present value (NPV) basis over a conservative 10-year horizon compared with low sulphur fuel oil, with paybacks varying from less than one year to five years.

Vessel type / trade route           


Liner (14,000 TEU Asia – US West Coast) 1-2 years
PCTC (6,500 CEU Atlantic US East Coast – Europe) 2-3 years
PCTC (8,000 CEU Pacific US West Coast – Asia) <2 years
VLCC (Arabian Gulf – China) 3-5 years
Capesize bulker (Australia – China) 2-4 years


The analysis excludes any financial benefits, for example through carbon pricing, from the lower greenhouse gas emissions from LNG compared traditional marine fuel oils.
