Monday - Friday : 8:00 to 17:00

BOR Calculation Online

1. BOR Calculation Online

Volume (m³): BOR (%)=:

 

Radius (m):
Insulation Thickness (m):

Note:

1) The calculation above only provides a simplified BOR value with 95% filling rate on Type-C tank.

2) The LNG is assumed as steady and static condition, the sea condition is assumed as calm and ideal, i,e the vibrations, fuel sloshing, sea area, weather and other dynamic conditions will not be considered in this calculation.

3) The result above is for reference only, Passer Lanyu will not take responsible for the accuracy of the results. For Detail Information, please send email to info@lanyu-insulation.com
