L&T Engineering in Powai & Vadodara are responsible for all the engineering activities pertaining to individual project under execution by Business Units of L&T. These centers offer skills and expertise for undertaking residual process engineering and detailed engineering activities. In addition to the above, it also supervise pre-commissioning and commissioning activities, undertakes trouble-shooting and provides technical support to proposal engineering.

It is equipped with the latest engineering software such as Aspen Plus, HYSYS, HTFS suite, FRI suite, STAAD-III, Caesar-II, CAE PIPE, Pipenet, Phoenics, Pvelite, Codecalc2, ETAP/EDSA, Intools, ANSYS, NISA, CFX, etc. L&T Engineering at Mumbai has successfully carried out modular design of thermal systems such as primary reformers & fired heaters and also modular design of the world’s largest CYCLEMAX Continuous Catalyst Regeneration (CCR) Unit using concurrent engineering techniques. In addition, it has carried out design and detailed engineering of cryogenic storage systems for ethylene, LPG and propylene; of cryogenic air separation plants and select process plants.

L&T follows the concept of Concurrent Detailed Engineering for the plant design and engineering using the Intergraph 3D Plant Design System (PDS) software from Intergraph. This package is used for developing a 3-dimensional model of the project encompassing all related aspects including the layout, piping, mechanical, electrical, instrumentation and civil engineering disciplines. Some of the direct benefits derived from this 3D PDS system include auto-extraction of piping isometrics from the 3-D CAD models, auto-extraction of structural fabrication drawings through soft-wares such as X-Steel, checking of interference between various elements of piping/ equipment / structural / instrumentation etc. through the simulated ‘walk-throughs’ and so on. Most of the recent complex projects executed by L&T are modeled on the PDS in order to derive the benefits stated above.

L&T Engineering has won the prestigious award from the Indian Chemical Manufacturers Association (ICMA) for the year 1997 for excellence in Chemical Plant design and engineering. This award was given for the design and engineering work related to design of different process plants including Complex Projects and Modular Process Plants.

it is supported by the specialized Engineering groups namely the FEED Group (Front End Engineering & Design), the Technology & Innovation Center (TIC) and the Research & Development Center.

As a step toward strengthening the Engineering capabilities of the company, L&T established two Joint Venture Engineering Companies namely, L&T - Chiyoda Limited (LTC) for hydrocarbon process plants and L&T - Sargent & Lundy Limited (LTSL) for power plants, both located at Vadodara. These joint venture engineering companies offer skills and expertise for undertaking detailed and residual engineering across a wide spectrum of industries.

L&T - Chiyoda Limited (LTC), is a joint venture company of L&T, Chiyoda Corporation of Japan and Sumitomo Corporation of Japan. LTC provides complete range of engineering services to both L&T and Chiyoda, for residual and detailed engineering, procurement and commissioning assistance for the projects in hydrocarbon sector.

L&T - Sargent & Lundy Limited (LTSL) is a joint venture engineering company, formed in collaboration with Sargent & Lundy of USA, who is world leader & has more than 100 years of experience in design of more than 700 power plants of various configuration. LTSL offers high quality engineering services for power projects in India and abroad.

Both these joint venture engineering companies are equipped with the state-of-the-art hardware and software facilities operating in networking environment, experienced engineering professionals and strong database to undertake basic and detailed engineering assignments. These function as captive engineering resource for the E&C Division. LTC and LTSL, backed up by their overseas parent companies are operating as centers of engineering excellence.
