Integrated Subsea Solutions

What Integrated Subsea Solutions does

Integrated Subsea Solutions Pte Ltd is a Singapore-based, privately-held subsea and marine contracting firm that acts as a complete subsea solution provider for oil and gas operators and offshore construction companies in Southeast Asia. Its service offering spans four pillars: offshore construction engineering (IRM and turnkey project execution), subsea support vessel provision (DP2 Diving Support Vessels and ROV vessels), saturation and air diving services, and contracting management. The firm operates an asset-light model, drawing on partner-owned vessels, a named ROV fleet (MOHAWK, MOHAVE, SUPERMOHAWK, TRITON), and a Classed Air Dive System rather than owning the underlying marine hardware.

The company delivers services across six regional markets (Malaysia, China, Indonesia, Thailand, Vietnam, and Myanmar) through a network of local subsea partners, positioning itself on the basis of localized expertise and what it describes as affordable offshore experience. Its team is composed of oil and gas professionals with more than 25 years of offshore construction experience, and the company has executed enterprise-scale projects including a Pertamina Hot Tap EPCIC scope (manifolds, hot taps, spools, inline valves, plus two DSVs), an Enhanced Mercury Removal project for COPI in the Banang Field, and salvage/HFO removal support for the sunken Thorco Cloud. The firm is small (1-10 employees), single-office, and does not disclose revenue, funding, ownership, or founding date.

Commercially, ISS runs a direct, sales-led engagement model: comprehensive consultation to identify technical requirements, budgets, and risks, followed by quote-based project pricing. Pricing is not publicly disclosed. Go-to-market relies on its own website, direct phone/email contact, and project-execution reputation rather than paid marketing or channel partners. No public certifications, patents, awards, or regulatory actions are disclosed, and there is no evidence of external funding, M&A, or leadership changes.

Direct peers

• Mermaid Maritime: Thailand-headquartered subsea services company providing ROV, diving, and vessel-based IRM and construction support across SE Asia, directly overlapping ISS's core service portfolio and regional footprint.
• Vallianz Holdings: Singapore-based offshore marine services company operating a fleet of support vessels and offering subsea construction and IRM-adjacent services to the regional O&G industry, mirroring ISS's vessel-representation and project execution model.
• Helix Energy Solutions: Provider of subsea well intervention and IRM services using specialized vessels and ROVs, with a comparable business model of bundling marine assets, diving, and engineering for subsea operations.
• ROVOP: Independent ROV operator offering inspection, maintenance, and light construction support to the offshore energy industry; directly comparable to ISS's ROV (MOHAWK/MOHAVE/SUPERMOHAWK/TRITON) service line.
• Pacific Radiance: Singapore-based offshore support vessel operator with subsea construction and ROV capabilities serving SE Asia O&G clients, directly comparable to ISS in terms of subsea service delivery and regional charter model.

Broad incumbents

• McDermott International: Global provider of engineering and construction solutions for offshore energy, with subsea IRM and SURF capabilities in the Asia-Pacific region; competes on larger integrated scopes ISS also targets.
• Saipem: Large international EPC contractor with offshore and subsea capabilities across SE Asia; competes with ISS for integrated subsea construction work and sets the competitive ceiling on regional tendering.
• Subsea 7: Global subsea engineering, construction, and services company with a major APAC presence; competes with ISS for larger EPCIC scopes and is a likely prime contractor that ISS could support as a local subcontractor.
• Sapura Energy: Malaysian integrated energy services company with a significant subsea construction, diving, and offshore vessel division, serving many of the same NOC clients (PETRONAS, Pertamina) as ISS in the region.

Regional players

• Bourbon Corporation: French-headquartered offshore vessel and subsea services provider with APAC exposure, offering ROV and marine support services similar in scope to ISS though primarily serving different geographic regions.
