Over the last decades the increased use of LNG has resulted in more interest in nearshore terminals. At such terminals this potentially hazardous cargo is not inside a port, nor near a city center. However, long waves (or infragravity waves) present at such relatively exposed locations can lead to excessive vessel motions. This particularly applies to LNG vessels, which show limited motion damping. Numerical methods that can calculate long wave conditions were typically developed and validated for the shallow coastal zone, say
