What DISA International does

DISA International is a Belgian-headquartered marine and subsea services company delivering turnkey underwater solutions across civil construction, offshore renewables, offshore oil and gas, salvage, and landfall projects. Founded in 2003 and organized under DISA International Holding BV, the group operates through operating entities in Belgium, the Netherlands, Singapore, the USA, Germany, and Denmark, with wholly-owned subsidiaries including SKEYE BV (drone inspection) and LEDI Subsea Drilling BV (subsea HDD). The company's core capabilities span commercial diving, ROV operations, survey and positioning, UXO services, cutting and welding, ballasting and suction operations, and specialized subsea concrete pouring, supported by proprietary tools such as custom automated chainpullers and bespoke vessel monitoring systems. DISA's track record includes over 100 completed projects globally, with marquee references such as the Costa Concordia salvage, the Blankenburgverbinding (100,000+ m³ of reinforced underwater concrete), the Lock IJmuiden caisson sinking, and the MV Napoli wreck removal, and the company installs 90,000-120,000 m³ of subsea concrete flooring annually.

The company generates revenue through long-cycle, project-based engagements priced on a quote-by-quote basis with working/standby day rates, mobilization/demobilization surcharges, and pass-through of consumables and tooling. All projects are acquired through direct enterprise sales to civil engineering consortia, offshore energy operators, port authorities, and marine salvage principals; no reseller or marketplace channel is used. Go-to-market is anchored on a comprehensive project reference list, ISO 9001/14001/45001 and Safety Culture Ladder certifications, and the ability to mobilize globally at short notice on a 7-day/12-hour/28-day rotation cycle. In 2024, DISA executed two strategically significant transactions: the merger of its offshore wind subsidiary C-VENTUS with Føn Energy Services (with DISA becoming a shareholder and board member), and a strategic investment and division merger with BlueTack, reinforcing its incident management and pollution remediation capabilities in the salvage segment.
