Holland Diving International

What Holland Diving International does

Holland Diving International BV is a privately held Dutch marine services contractor founded in 1972, headquartered in Schiedam with operational offices inside the Rotterdam and Antwerp port areas. The company performs underwater ship maintenance, repair, inspection, and class-certified survey services for commercial vessel owners and operators, using surface-supplied (rather than scuba) diving with certified professional dive technicians. Service delivery is supported by fully equipped workboats fitted with deck decompression chambers, mobile workshop vans for rapid mobilization, and state-of-the-art underwater repair equipment covering cutting, cropping, welding, grinding, drilling, bending, and cleaning operations. The portfolio spans core ship maintenance and repairs plus specialized lines — Corrosion Control, Propulsion Works, Inspection UW & NDT, Inshore Civil works, and Ship Surveys — accepted by all major classification societies (ABS, DNV, Bureau Veritas, RINA, ClassNK, Lloyd's Register, CCS) under ISO 9001 quality management and VCA safety certifications.

The business operates a sales-led, contact-based go-to-market model with 24/7 availability: customers reach out, HDI provides tailored quotations, and the company mobilizes professionals and equipment to the vessel. Pricing is quote-based and project-specific, with no publicly disclosed rates. Direct service delivery is anchored in the ARA (Amsterdam-Rotterdam-Antwerp) port corridor, and worldwide coverage is delivered through a 'Reliable Partners Network' that extends HDI's mobilization capability on a 24/7 basis. The company holds NADO (Dutch Association of Diving Contractors) membership and is independently owned with no disclosed parent company, institutional investors, or external equity structure. There are no disclosed revenue figures, no funding rounds, no acquisitions, and no digital product or AI capabilities referenced in the available materials.
