Raising The Roof With In-House Capabilities

Networked for Innovation

L&T executes projects and develops products of national significance across India and other select geographies. We recognise the responsibility that comes with our large-scale operations. It propels us to undertake measures to reduce the environmental, health and safety (EHS) impact of our offerings across their lifecycle while maximising economic benefits. To ensure this, we have a comprehensive EHS management system at our manufacturing facilities and project sites to identify, manage and minimise such risks.

Our practices in EHS management need the support of our supply chain partners including contractors, as they play an important role in overall Carbon footprint reduction. We encourage them to be safe, efficient and reliable with minimal EHS impact as they work at our facilities, and during the transportation of our products. We extend our environmental and social practices to the supply chain and are committed to implementing our Environment and Social Code of Conduct, which is now a part of the Supplier Agreements.

E&A business filed 101 patents, three trademarks, four design applications in India, along with two foreign patent applications (in Malaysia) and 18 foreign trademark applications (in Indonesia, Vietnam and Malaysia) during 2016-17. This was the 10th consecutive year where we filed more than 100 patent applications. The business received grants for 50 patent applications (in India, USA, Australia and Europe).

Our Approach to Product Stewardship includes:

	Management systems and internal audit processes to assess, prevent or mitigate potential EHS risks to our workforce at our facilities and project sites.
	Screening of suppliers and their working to enhance environmental and social performance throughout the supply chain and to promote responsible use of our products.
	Providing adequate information to our customers regarding the use of our products.
	Extending our ‘Green Products and Services’ portfolio, which helps customers improve their environment footprint and move towards a low carbon path.

Raising the roof with in-house capabilities

L&T Hydrocarbon Engineering (LTHE) developed the in-house capability for roof-raising in Cryogenic Tank Projects. At the Reliance Dahej site, the Company is executing a project involving cryogenic ethane/LNG tank construction. A steel roof along with other structural attachments (total 850 MT) has to be lifted to an elevation of 37 m for the construction of the tank. This is done by using four air blowers, located at a temporary opening in the outer tank wall, at the ground level. Cryogenic tank roof-raising forms a critical part of the Cryogenic Tank construction process and requires meticulous planning and strict quality checks to ensure that the roof is lifted in a well-balanced manner, flawlessly. It took a dedicated engineering team, months of planning and utilisation of their combined expertise to execute this task successfully. The roof-raising operation was completed in seven hours. It took another 5 hours to weld it in place along with a compression ring at the top. The businesses’ in-house capabilities resulted in savings of

11 million, along with enhanced control of the process, and improvements in quality, safety and execution speed. The learnings and expertise gained will hold LTHE in good stead for executing similar projects in future.
