In version 2018.2 some corrections have been introduced to the calculation of the reinforcement of the openings of Division 1. Some of these corrections can lead to the reduction of the area available for reinforcement, particularly:
Further corrections may lead to an increase in the available area, in particular:
The calculation of the area to be compensated when there are oblique or off-center nozzles has been corrected. The “additional area due to obliquity” was previously set to zero, now this value is correctly calculated. The area to be compensated could therefore increase.
Until now, the surface area exposed to the wind for this kind of component has always been optional. We have decided to make it mandatory, so as to make the user more aware of the need to insert this data, which can sometimes be a determinant in the presence of considerable exposed surfaces. Upon opening, the files containing this component will show validation errors for “missing required properties”. Simply open the “platform” components and then enter a non-zero value in “External Loads”> “Area exposed to wind”. The requested value is the surface area of the portion of platform section that is outside the vessel’s section.
