SEAMEC is a vessel-owning company that rents out specialised ships and diving crews to oil and gas companies for underwater work - essentially a floating toolkit for subsea construction and repair. It was born from a leasing company in 1986, passed through the hands of global offshore groups Coflex Stena and Technip, and landed in 2014 with the Indian conglomerate MMG Group, whose other businesses include Coca-Cola bottling and McDonald’s franchises. The recurring pattern is simple: buy or secure a vessel, lock it into a multi-year charter with a national oil company or large contractor, and let the day rate generate cash - then repeat with a bigger or different ship.
Business segments
Two engines at different stages - a specialised offshore fleet that is the company’s cash cow, and a small bulk-carrier division that was meant to de-risk it, now being reshaped through a new ship-leasing joint venture.
1. Offshore vessel services: the subsea fleet that oil companies rent
SEAMEC owns one of the largest fleets of Diving Support Vessels in the Asia-Pacific region and earns its living by charging a daily hire rate, mostly on contracts lasting three to five years.
- A fleet built around divers - The company operates six Diving Support Vessels (DSVs), one Offshore Support Vessel (OSV), and one accommodation barge, all designed to put divers and remotely operated vehicles (ROVs) onto subsea oilfield infrastructure. A DSV is a floating platform with a built-in diving system and dynamic positioning (computer-controlled station-keeping), which lets it sit precisely over a pipeline or wellhead while crews inspect, repair or build underwater.
- Paid by the day, mostly on long charters - Revenue comes from charter hire, meaning the client pays a fixed daily rate for the vessel and crew regardless of how many dives are done. The majority of contracts run three to five years at firm rates, which gives revenue visibility; a smaller slice is spot work where rates swing with demand. The core vessel business targets sustainable margins of around 40% to 45%.
- ONGC is the anchor customer - India’s national oil company accounted for roughly three-fifths of total revenue in FY24, and the relationship stretches back many years. Getting pre-qualified to bid for ONGC is a long and difficult process, so once a vessel owner is inside the approved list, it faces fewer rivals. Other clients include Saudi Aramco, ADNOC, and L&T Hydrocarbon Engineering.
- The moat is the fleet size and local protection - Most competitors own only one or two DSVs, so SEAMEC’s six-vessel line-up lets it bid for multiple contracts simultaneously and offer clients backup capacity. Foreign vessel owners face government barriers that make them reluctant to enter Indian waters, which further narrows the competitive field.
- Services go beyond the ship - The company also takes on operation and maintenance (O&M) contracts for vessels that clients already own, running the crew and upkeep for a fee. In consortium with a partner, it recently won O&M work on two ONGC-owned vessels, “Samudra Sevak” and “Samudra Prabha,” for 2026-2028.
2. Bulk carrier division: a small dry-cargo sideline, now pivoting to ship leasing
Originally a diversification play to offset the oil-and-gas cycle, the bulk shipping business today is a two-vessel operation run through Dubai subsidiaries, with a new GIFT City joint venture pointing toward a different model.
- Three ships carrying dry commodities - The division moves industrial raw materials - cement, coal, scrap, food staples - through two Handymax bulk carriers, SEAMEC GALLANT and ASIAN PEARL. Revenue is freight hire, and charter rates move with the Baltic Dry Index, a benchmark that tracks the cost of shipping dry bulk across global routes.
- Run from Dubai, selling to Indian industrials - The ships are owned and managed through SEAMEC International FZE (a wholly owned subsidiary in the Dubai Airport Free Zone) and its step-down joint venture Seamate Shipping FZC. Customers are large Indian commodity buyers - Adani, JSW, Tata, UltraTech Cement - who need raw materials moved by sea.
- A new leasing venture in GIFT City - In 2025, SEAMEC’s Dubai arm formed a 50:50 joint venture called SEARETE INDIA IFSC, registered in Gujarat’s GIFT City special economic zone, to buy ships and lease them out on bareboat charter (a rental of the vessel alone, without crew or operating costs). The venture immediately bought a vessel, “CHENNAI VALARCHI,” and placed it on a 42-month bareboat charter at about USD 7,156 per day, generating roughly USD 9.15 million in total hire.
Group structure and partners
SEAMEC sits inside the MMG Group, controlled by a parent that does similar underwater work, and operates through a web of subsidiaries in the UAE, UK, and India that hold ships, pursue new geographies, and own supporting land.
- HAL Offshore is the 70% parent and a close collaborator - HAL Offshore Limited, the promoter, is itself an underwater-services and EPC contractor to Indian oil and gas, and it charters vessels to SEAMEC and subcontracts work back from it. The two companies together represent a significant combined service provider in the sector.
- Dubai houses the international operations - SEAMEC International FZE (wholly owned) and Seamate Shipping FZC (60:40 JV with Arete Shipping) own and manage the bulk carriers and handle overseas vessel deployment.
- A UK subsidiary eyes Europe and Africa - Seamec UK Investments Ltd, incorporated in 2023, was set up to explore oil-and-gas business in Europe and Africa, with three step-down entities yet to commence operations.
- A land bank for fabrication - Aarey Organic Industries Private Limited was acquired in 2023 for the purpose of having its own fabrication and storage unit, and its land will be developed into storage, warehousing, and fabrication facilities to support an expansion into EPC and fabrication work.
