NASS Engineering

What NASS Engineering does

NASS Engineering Services Pvt Ltd is a marine, offshore, and industrial engineering services company incorporated in 2016 and headquartered in Navi Mumbai, India. The company provides diesel engine overhaul, propulsion system maintenance, in-situ machining (orbital crankshaft grinding, cylinder liner honing), vibration analysis, laser alignment, and afloat repairs through deployable marine riding squads, eliminating the need for dry-docking. Core technology centers on portable precision tooling for in-situ interventions on marine diesel engines, supported by ISO 10816-3-compliant diagnostics, and includes authorized distribution of Bosch fuel injection systems, MANN+HUMMEL centrifugal filters, ENI and MAK lubricants, and supply of new and reconditioned Detroit and CAT engines. The company is dual-structured as an India private limited entity with wholly-owned subsidiaries in Saudi Arabia (Dammam), UAE (Ras Al Khaimah), Qatar (Doha), and Oman (Muscat), giving it a "India-cost / GCC-presence" operating model with rapid (<12 hour) mobilization to Arabian Gulf and Red Sea ports.

NASS generates revenue across three streams: (1) professional services contracts for engine repair, riding squad deployment, and afloat overhauls billed per project; (2) hardware sales of genuine OEM spare parts, filters, and lubricants through its authorized distributor network; and (3) supply of new and reconditioned marine diesel engines with Dyno Test certification. Its customer base spans commercial shipping fleets, offshore oil & gas operators (including Aramco-compliant OSV work), Indian defense (Indian Navy aircraft carriers, Coast Guard), state-owned shipyards (Cochin Shipyard, Goa Shipyard), Shipping Corporation of India, and power generation operators. Pricing is custom and quote-based per engagement. Operations are supported by ISO 9001:2015 (IRQS) and ISO 9000-2015 (IRS) certifications, IADC and Shipserv memberships, and classification society validation capabilities (ABS, DNV, IRS).

The company is privately held and founder-controlled, with Naseeruddin Athar as the primary contact across all branches. Reported headcount is approximately 10 employees, indicating a lean specialized firm that likely augments field execution with contract riding squads. Geographic scope covers India and the GCC, with the website positioning the company as a regional alternative to European OEM service networks by combining India-cost engineering labor with on-the-ground Gulf presence.
