Our Achievements

Indian Navy Verified Vice Admiral Ravneet Singh, Deputy Chief of the Naval Staff, dedicated the modernised Material Organisation (MO), Goa to Indian Naval Aviation on 28 March 2022. The turn-key project, executed by M/s Ultra Dimension Private Limited for modernisation of MO, Goa, is the first of its kind in the #IndianNavy. It was executed in four phases without affecting the day-to-day functioning of the Depot. Key deliverables included installation of customised storage solutions to enhance storage capacity, augmentation of state-of-the-art electrically-operated material handling equipment to facilitate safe and efficient stowage and retrieval, and maintaining a pollution-free environment within store houses. An Automated Storage and Retrieval System (ASRS) has been commissioned and will ensure optimal storage and issue of smaller and fast moving items with minimal human intervention. The project also included air conditioned storage spaces for specific spares, installation of surveillance cameras and centralised automatic fire detection and alarm system. Design and manufacture of all equipment has been undertaken completely in India to boost the GoI initiative of #AatmanirbharBharat. #HarKaamDeshKeNaam 3w
