What MarineMasters does

MarineMasters (legal entity Marine Masters B.V.) is a Dutch privately held maritime services firm founded in 2016 by Henk Smith and Danny Spaans, headquartered in Schiedam (Rotterdam port area) with a regional headquarters in Kuala Lumpur opened in January 2025. The company delivers four core services: decommissioning of offshore oil and gas infrastructure, transport and installation of offshore structures, 24/7 emergency response and salvage, and wreck removal, serving enterprise clients in offshore energy, maritime insurance, ship owning, and port authority / government segments. MarineMasters operates an asset-light model, executing projects as main contractor while sourcing fit-for-purpose vessels and heavy-lift assets regionally through a partner network that includes Fagioli, Bonn & Mees, Mer-Terre, Muhibbah Engineering, and Aras Salvage.

The company differentiates on the combination of engineering-led project planning with a salvage-oriented mindset, backed by proprietary in-house equipment: a Hot Tap system for safe hydrocarbon removal from damaged or sunken vessels, a portable Suitcase ROV for hull and seabed inspection without dive teams, and patching equipment for sealing and stabilizing compromised hulls. It holds Full Membership in the International Salvage Union (since 2021) and is a member of the Rotterdam Marine Cluster, underscoring industry credibility. Revenue is earned on a per-project, professional-services basis via tenders and direct enterprise sales, with no publicly disclosed pricing; the largest disclosed single engagement is the $15 million USD South Angsi Alpha decommissioning and rig-to-reef project for Hibiscus Oil & Gas Malaysia, which the firm executed as main contractor in 2025. The firm is bootstrapped and founder-owned, with no external venture capital, private equity, or parent company identified.
