Aquatech Group

What Aquatech Group does

Aquatech Group is a Netherlands-headquartered holding company that delivers professional commercial diving services and underwater construction across two integrated divisions. Aquatech Diving, founded in 1996, performs inshore civil underwater works — including aquaduct, tunnel, quay, lock, sluice, and bridge construction, plus ship maintenance, salvage, and inspections — for Dutch and German contractors and government authorities. Aquatech Offshore, founded in 2022, extends the platform into subsea Oil & Gas IRM, offshore renewable energy support (notably wind-farm cable repair and foundation intervention), and subsea decommissioning campaigns in the North Sea.

The combined group operates an IMCA-compliant equipment pool that is unusually deep for its size, including an in-house developed ABS-class dual-diver Launch and Recovery System (LARS), DNV 2.7-1 certified dive control and deck decompression chambers, compressor and airbank units, an IMCA-compliant Scuba Replacement System, a 16" airlift, and two purpose-built vessels (the fast rescue craft Jouke and the urban-canal work boat Ivor). Projects cited include the Wesertunnel Bremen underwater construction works, the New Waterworks Zoutkamp flood protection scheme for Waterschap Noorderzijlvest, the Singelgracht Parking Garage Amsterdam build, the Kornwerderzand lock at the Afsluitdijk, North Sea gas-pipeline stabilisation for NOGAT, and offshore wind cable replacement.

Aquatech monetises entirely through project-based professional services contracts won via direct engagement, tenders, and partnerships with prime contractors and government agencies. The holding company (Aquatech Holding B.V.) was formed in 2023 to integrate the two divisions under a single QHSE-managed organisation based in Joure, with revenue and financial performance not publicly disclosed.

Scale indicators2 records

Recent moves7 records

Expansion highlights4 records

Broad incumbents

• Fugro: Dutch subsea geotechnical and inspection services company that performs ROV and diver-based subsea inspection on offshore wind, oil & gas and infrastructure projects. Overlaps with Aquatech in offshore IRM and inspection scopes.
• Van Oord: Dutch offshore contractor active in offshore wind installation, subsea cable laying and dredging. Competes for offshore renewables work and Dutch coastal civil scopes that overlap with Aquatech's project base.
• Boskalis: Large Dutch maritime services group with diving, subsea and offshore energy capabilities that often bid on the same Dutch civil and North Sea projects. Acquired Rever Offshore in 2022, expanding its diving service portfolio overlapping with Aquatech's offering.
• Subsea 7: Global subsea construction, IRM and renewables company with significant North Sea diving operations. Operates at much larger scale but competes for the same subsea IRM and offshore wind installation support tenders.
• DOF Subsea: Norwegian-headquartered global subsea contractor offering diving, IMR, and subsea construction across the North Sea. Comparable in offshore IRM and diving service delivery though materially larger and globally diversified.

Direct peers

• De Klerk Waterbouw: Dutch inland water construction and diving contractor specializing in civil underwater works, quay and lock construction, and ship maintenance. Directly comparable to Aquatech Diving's inshore civil scope and customer mix.
• Stemat Marine Services: Dutch subsea services and diving contractor with comparable focus on offshore IRM, cable work, and shallow-water diving operations in the North Sea. Similar scale and regional footprint make it the closest direct comparable to Aquatech Offshore.
• Helix Energy Solutions: US-based offshore services company specializing in subsea well intervention, ROV and commercial diving operations. Directly comparable diving-based service model though operating in Gulf of Mexico rather than the North Sea.
• A.Hak: Dutch pipeline and cable installation contractor with subsea capabilities relevant to offshore cable repair and pipeline work. Comparable in scale, Dutch base, and overlap with Aquatech's subsea cable and pipeline intervention scopes.

Others

• Royal IHC: Dutch manufacturer of dredging, offshore and subsea equipment including diving systems and vessel designs. Serves the same North Sea ecosystem and could be an equipment supplier or partner for Aquatech rather than a direct competitor.
