L&T-Chiyoda Leverages CAESAR II for Malaysia Refinery Project


L&T-Chiyoda’s Larsen & Toubro Heavy Engineering Division (LTHED) was awarded a US$35 million project to design, manufacture, and supply the reactor-regenerator package for two residue fluid catalytic cracker units at the RAPID refinery project for PETRONAS in Malaysia.

The refinery project involved many complexities including tight deadlines and very high operating temperatures of 800 to 900 degrees Celsius, and pipe ranging from ½ inch to 82 inches in diameter. LTC also had to interpret two ASME piping codes simultaneously.

With CAESAR II, the group could determine material specifications and order early, saving significant time, and quickly check for clashes to decide pipe routing, expediting client approvals, all without a 3D model.

“CAESAR II made analysis extremely simple, time-saving, and cost-effective. It made the design safe and reliable, and without manual errors,” explained Pradeep Darji, lead pipe stress engineer and general manager at LTHED.


LTC received the 2016 CAESAR II Drivers of Success Runner-Up Award for its use of the software. The annual Drivers of Success competition recognizes innovative applications of Hexagon PPM products, impressive project results, and significant benefits from collaboration among disciplines and the integration of the products.
