Cyan Renewables

What Cyan Renewables does

Cyan Renewables is an offshore wind services platform headquartered in Singapore that operates a fleet of 35 specialized vessels supporting the global energy transition. Founded in September 2022 with backing from Singapore-based private equity firm Seraya Partners, the company provides marine and subsea services across the full offshore wind lifecycle—from geophysical and geotechnical surveys through installation, operations and maintenance, and decommissioning. Its vessel classes include Service Operations Vessels (SOVs), Walk-to-Work/Construction Support Vessels, Multi-Purpose Support Vessels, Platform Supply Vessels, Emergency Response and Rescue Vessels (ERRVs), and Anchor Handling Tug Supply Vessels. Notable technical assets include Dynamic Positioning (DP2) systems, motion-compensated Walk-to-Work gangways, SWATH-designed hulls, and Siemens BlueDrive PlusC propulsion with hybrid battery systems; the company also offers high-strength grouting, stabilization, subsea IMR, and engineered artificial reef solutions.

The company serves offshore wind developers, energy companies, government and defense organizations, and environmental agencies. Named enterprise customers include Siemens Gamesa (15-year SOV charter for the 1,044 MW Hai Long project in Taiwan) and the Australian Department of Defence under the HydroScheme Industry Partnership Program (HIPP). Cyan generates more than US$100 million in annual EBITDA and operates across Singapore, Australia (Perth, Welshpool, Melbourne), South Korea (Seoul), Taiwan (Taipei), the United Kingdom (Aberdeen, Fordoun, Stonehaven), and Denmark (Esbjerg), supported by approximately 1,600 onshore and offshore staff.

Cyan's revenue model is anchored in long-term vessel charter contracts (including the 15-year SOV agreement) supplemented by project-based and recurring subsea engineering, IMR, grouting, stabilization, survey, and environmental services, with pricing negotiated directly under multi-year enterprise contracts. The platform has scaled primarily through acquisitions—Sentinel Marine (75% stake, July 2023), Groenewind SOV (from DEME, 2023), and the landmark A$1.1 billion take-private of Australian-listed MMA Offshore (completed July 2024), adding ~20 offshore support vessels and full subsea engineering capabilities. Cyan's sub-brands include Cyan Sentinel (ERRV/MRV operator in Europe) and Groenewind (purpose-built SOV); MMA Offshore was rebranded to Cyan Renewables effective 14 July 2025.

Expansion highlights7 records

Direct peers

• Esvagt: Danish SOV operator headquartered in Esbjerg with a large fleet serving European offshore wind farms. Comparable to Cyan's Cyan Sentinel ERRV/MRV business and the European SOV charter strategy, with similar long-term contracted revenue profile.
• Edda Wind: Norwegian SOV and CTV operator dedicated to offshore wind, listed on Oslo Børs. Highly comparable business model focused on long-term charter contracts with European wind developers, mirroring Cyan's Hai Long-style contracts.
• Cadeler: Pure-play offshore wind turbine and foundation installation vessel operator formed from the merger of Swire Pacific Offshore and Eneti. Directly comparable as a vessel-based service provider to global offshore wind developers, competing head-to-head with Cyan for WTIV and foundation installation contracts.
• North Star Renewables: UK-based SOV operator serving the European offshore wind market with a growing newbuild SOV fleet. Direct overlap with Cyan Sentinel in the UK/North Sea SOV charter segment.

Broad incumbents

• Solstad Offshore: Norwegian OSV operator with PSVs, AHTSs, and subsea construction vessels. Comparable fleet composition to Cyan's non-wind OSV fleet and overlapping in subsea services.
• Siem Offshore: Norwegian OSV owner-operator with SOVs, PSVs, and subsea construction vessels serving offshore wind, oil and gas, and other offshore markets. Comparable vessel mix to Cyan and active in the same European charter market.
• BOURBON: French-headquartered global OSV operator with a large fleet of PSVs, AHTSs, and crew boats serving offshore energy markets. Comparable broad offshore marine services footprint though more oil-and-gas weighted than Cyan's wind-focused fleet.
• DOF Group: Norwegian offshore support vessel group with AHTS, PSV, and subsea construction capabilities. Broader incumbent offering overlap with Cyan's AHTS/PSV fleet and subsea services, though less specialized in wind-only SOV/CTV segments.

Emerging players

• PACC Offshore Services Holdings (POSH): Singapore-listed OSV company where Cyan's Group CEO Lee Keng Lin previously served as CEO for 15+ years. Closely comparable Asia-anchored OSV platform and a natural competitor for APAC offshore wind vessel contracts.

Others

• VARD (Fincantieri): Norwegian shipbuilder (Fincantieri subsidiary) that built the Cyan Wind Seeker SOV. Functions as a key vessel supplier and strategic partner rather than a direct competitor, but central to the offshore wind vessel value chain.
