Yeoman Marine Services

What Yeoman Marine Services does

Yeoman Marine Services Private Limited is a privately held Indian maritime engineering company founded in 1999 by Dhananjay Mishra and headquartered in Mumbai, with operations across 13+ Indian locations including all major naval yards (Mumbai, Vishakhapatnam, Kochi, Karwar, Andaman & Nicobar) and commercial ports. The company delivers an integrated portfolio spanning shipbuilding, ship repair and refit, marine infrastructure (pontoons, caisson gates, barges), defence products, and equipment sales/services, with the shipbuilding segment representing approximately 50% of revenue. Its flagship 27-acre Ratnagiri Shipyard (acquired in 2021 from the former Bharati Defence and Infrastructure Ltd) provides in-house fabrication capacity for the NGOPV programme and commercial vessel construction.

The company's core technology capabilities span engineering, hull and structures, electrical and electronics, controls and IPMS (Integrated Platform Management System), weapon system installation, and indigenization of naval spares. Its proprietary RESS (Remote Embedded Systems Support) system — a patent-pending, satellite-based remote diagnostics and maintenance platform — enables ships and submarines to receive defect rectification support at sea without returning to harbour. Yeoman also serves as the authorised Indian representative for 12 international OEMs (Goldring, Idromar, Vestdavit, Lehavot, FAPMO, NIDEC, Navint, WOODPLC, Lamor, Lignum Vitae, Ibercisa), bundling equipment supply with installation, commissioning, and lifecycle support through AMCs and spare parts contracts.

The business model combines turnkey defence shipbuilding and refit contracts (largely one-time project-based), professional services for ship repair and marine infrastructure, hardware sales of equipment and OEM products, and recurring managed services through AMCs and spare parts supply. Go-to-market is enterprise field sales targeting the Indian Navy, Indian Coast Guard, DPSU shipyards (MDL, GSL, CSL, HSL, GRSE), ONGC, SCI, and select international commercial clients (Bourbon, Sea-Cargo, Damen, Qatar Shipping), supplemented by event-led positioning at Nor-Shipping and Defexpo. Customer mix is heavily weighted toward Indian defence and government-adjacent segments, with the company certified to ISO 9001/14001/45001 and vessels classed by DNV, BV, LR, ABS, and IRS.

Scale indicators10 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Naval Group: French naval shipbuilder and combat-systems integrator (Scorpene-class submarine designer alongside MDL's build). Overlaps with Yeoman in submarine sustainment, IPMS integration, and naval refit work at the broader portfolio level.
• Larsen & Toubro (Defence): India's largest private defence engineering and shipbuilding conglomerate, active in naval platforms, submarines (P-75I bid), and defence electronics. Competes with Yeoman for naval subcontracting share but operates at far greater scale across multiple defence verticals.
• Seatrium (formerly Sembcorp Marine): Singapore-based global shipbuilder and offshore rig converter with significant naval refit and offshore platform capabilities — comparable to Yeoman's ship repair/refit and offshore infrastructure (pontoons, caisson gates) work, but at much larger scale and broader geographic footprint.
• Fincantieri: Global shipbuilding incumbent with strong naval and offshore vessel portfolio; comparable to Yeoman in warship new-build, refit, and integrated platform management, though at significantly larger scale and with broader geographic reach.

Direct peers

• Goa Shipyard Limited (GSL): Lead shipyard for 7 of 11 NGOPV vessels where Yeoman fabricates main hull blocks at Ratnagiri and supplies RESS systems — GSL is both a direct customer and a directly comparable peer in fast-attack craft and OPV construction.
• Damen Shipyards: Dutch global shipbuilder of tugs, workboats, and naval platforms; Yeoman's strategic partner for tugboat production in India. Damen is directly comparable as a tug/workboat builder and competes in the same international commercial vessel space Yeoman targets.
• Cochin Shipyard Limited (CSL): Builder of IAC Vikrant and ASW Shallow Water Craft for the Indian Navy; Yeoman performed IPMS commissioning on IAC Vikrant and supplies shafting/equipment for CSL's NGOPV follow-ships — directly overlapping in naval new-build and refit.
• Mazagon Dock Shipbuilders Limited (MDL): India's premier submarine and destroyer builder (Scorpene, P15/P15B, P17/P17A) — Yeoman is an outfitting/IPMS subcontractor on the same platforms, making MDL the most direct peer in warship construction.
• Hindustan Shipyard Limited (HSL): Public-sector shipyard in Visakhapatnam building Large Survey Vessels for the Indian Navy with Yeoman supplying DSV RAS/FAS equipment — HSL is a directly comparable naval shipbuilder and refit peer.
• Garden Reach Shipbuilders & Engineers (GRSE): DPSU shipyard building ASW Corvettes and 4 of the 11 NGOPV hulls; Yeoman supplies RAS/FAS equipment and supports SVL/NGOPV work, making GRSE a direct naval shipbuilding peer and partner.
