The Sunkoshi Marin Diversion Multipurpose Project (SMDMP), designated as a National Pride Project by Nepal's Ministry of Energy, aims to transfer water from the Sunkoshi River to the Marin River, enhancing the Bagmati Irrigaion System and irrigating 122,000 hectares across several districts. The project includes a 13.3km tunnel and a 31.07 MW power station in Kamalamai Municipality.

The SMDMP is a pivotal development for Nepal, contributing not only to the country's agricultural sustainability but also to its energy production, supporting economic growth and flood control in the region.

For this significant project, Unicrane has supplied 7 sets of universal ring molds, with the specification OD 6.1m × 1.4m × 0.3m (6P/R), to produce high-quality tunnel segments. These segments are essential for constructing the diversion tunnel and ensuring the project's long-term operational efficiency.
