Unidive Subsea Pte Ltd

What Unidive Subsea Pte Ltd does

Unidive Subsea Pte Ltd is a Singapore-based commercial diving and subsea services provider founded in 1996, operating with approximately 80 employees across Singapore, Malaysia, Thailand, and select Asia-Pacific markets. The company delivers underwater inspection, repair, and maintenance services — including in-water surveys (UWILD), hull and propeller inspections, underwater welding and cofferdam installation, jetty structural maintenance, Single Buoy Mooring (SBM) inspection, and ROV-supported operations — to ship owners, oil & gas companies, and port operators. It is an approved diving contractor for ExxonMobil, Shell, Chevron, and BP, and works with all major classification societies (ABS, BV, LR, DNVGL, CSS, NKK, KR, IR) for UWILD approvals.

The company's technology stack centers on certified commercial divers and ROV assets, including the Seatronics Predator MK II (300m depth-rated inspection-class ROV) equipped with HD CCTV, Blueview sonar, and optional SeeByte CoPilot autonomy software. Operations comply with Singapore Standard SS511:2018 for diving, IOGP safety standards, IMCA Full Member requirements, and ISO 9001/14001/45001 certifications. The core differentiator is mobile dive-team deployment at ports and anchorages, allowing inspections during cargo operations or bunkering to eliminate off-hire periods and avoid expensive dry-docking.

Unidive generates revenue through project-based professional services contracts priced on scope, location, and operational requirements. The go-to-market is enterprise field sales, leveraging approved-contractor qualifications and long-standing relationships with International Oil Companies and ship owners. The group operates through two wholly-owned subsidiaries — Unidive Offshore Pte Ltd (offshore diving and ROV support) and Unidive Marine Services (Malaysia) Sdn Bhd (Malaysia, Kalimantan operations) — and is a founding member of the Commercial Diving Contractors Association of Singapore (CDAS).

Direct peers

• Mermaid Maritime: Thailand-listed offshore services group providing subsea inspection, ROV operations, and diving services across Southeast Asia, the Middle East, and West Africa. Directly comparable in service mix (UWILD, ROV, underwater inspection/repair) and in regional supermajor client base.

Broad incumbents

• DOF Subsea: Norway-headquartered global subsea IMR contractor operating ROVs and dive support vessels worldwide. Comparable in service offering (ROV inspection, UWILD, SBM support) and supermajor client base, with a broader global vessel fleet and deeper-water capability.
• Subsea 7: Global subsea contractor specializing in SURF, inspection, maintenance, and repair (IMR) of offshore pipelines, structures, and vessels. Comparable in delivering ROV-based inspection campaigns for oil-and-gas clients, but operates globally and at significantly larger scale.
• Van Oord: Netherlands-headquartered international marine contractor specializing in dredging, offshore wind, and subsea infrastructure. Comparable in underwater cable/pipeline installation and seabed intervention, particularly relevant if Unidive pursues offshore wind adjacent work.
• Boskalis: Netherlands-listed global marine services and dredging contractor with significant offshore energy and subsea services exposure including subsea cable installation and seabed intervention. Comparable in underwater infrastructure services, though at much larger scale and across a broader marine services portfolio.
• Helix Energy Solutions: US-listed offshore energy services provider with subsea well intervention, ROV, and decommissioning capabilities. Comparable in underwater inspection and intervention services for offshore operators, though it focuses more on well intervention and abandonment than UWILD/hull work.
• TechnipFMC: Global subsea engineering and services company offering integrated subsea inspection, intervention, and hardware solutions. Comparable in underwater inspection and intervention services to offshore operators, though typically engaged on larger integrated subsea field development projects.
• Saipem: Italy-headquartered global engineering and offshore contractor with a substantial subsea services division covering SURF, ROV inspection, and offshore field development. Comparable in UWILD/SBM-class work for supermajors but at vastly larger scale and with broader portfolio across pipelines, platforms, and drilling.

Regional players

• Vallianz Holdings: Singapore-based offshore marine services and vessel chartering company serving the offshore oil and gas sector in the Middle East and Southeast Asia. Comparable as a Singapore-headquartered offshore services company supporting supermajor and NOC clients in the same geography.
• PACC Offshore Services Holdings: Singapore-listed offshore support vessel operator serving oil and gas clients across Asia Pacific. Comparable as a regional Southeast Asia offshore services platform serving supermajor clients, though primarily focused on vessel provision rather than diving/ROV operations directly.
