Helipad on Fpso
Designing a helipad for a floating production storage and offloading (FpSo)
vessel requires consideration of various types of loads, such as the landing load
of the helicopter along with vessel motion and wind effects. A crash load is also
considered. For this $450,000 project in Singapore, Keppel Shipyard identified
126 load cases to analyze.
STAAD.pro was chosen for modeling, analysis, and design of the helipad
because it could process these load combinations within the short amount
of time available for the project. The software reduced costs by saving
engineering man-hours, improving design quality, ensuring safety standards
were met, and optimizing materials.

Ammonia Feedstock changeover project – reformer Area
Panipat and Bhatinda, India
one of India’s leading producers of nitrogenous fertilizers, national Fertilizers
limited operates fertilizer units in panipat and Bhatinda that use fuel oil/
low sulphur heavy stock as feedstock. The plants were operating above their
rated capacities of 900 million tons per day (m TpD) of ammonia and 1,550
m TpD of urea.
As part of an ammonia feedstock changeover project, larsen & Toubro performed
detail engineering of the reformer area. STAAD.pro was used for superstructure
analysis and design and S TAAD.foundation was used for foundation analysis and
design. microStation was used for 3D model transfer, visualization, and review.
These tools helped the project team to design both plants simultaneously and
complete detailed engineering within the stipulated project schedule.
