This paper aims to address long term loads and fatigue damage accumulation for different trading routes relative to North Atlantic operations based on IACS scatter diagram for a 216,000 m3 LNG carrier. The evaluation is based on direct wave load analysis using WASIM and scatter diagrams created in accordance with DNV Code 30.5 for the following trades: 1. North Atlantic 2. World Wide 3. Qatar - Boston 4. Qatar - UK 5. Murmansk - Boston 6. Murmansk - Rotterdam 7. St. Petersburg - Canada 8. Sakhalin - Mexico port close to California USA 9. Sakhalin - Shanghai, China It is found that in general Murmansk - Boston and St. Petersburg - Canada are the most severe routes after North Atlantic trade for the fatigue strength.
