DBB Dredging

What DBB Dredging does

DBB Dredging A/S is a Danish privately held marine contractor headquartered in Svendborg, Denmark, founded in 1984 (originally as Svendborg Uddybning). The company provides port dredging, port expansion, coastal protection, environmental sediment remediation, stonework, cable trenching, salvage, and pile driving services to Danish port authorities, municipal harbors, and major European construction firms. It operates a fleet of more than ten specialized vessels, including four backhoe dredgers (DBB Obelix, Jette Saj, Helle Saj, DBB Lillefix), two backhoe dredging barges (Nicolaj Saj, DBB Futte), two multicat workboats (DBB Asterix, DBB Idefix), and five split hopper barges, with a stated workforce of 50 employees.

All excavators are fitted with the PDS 2000 GPS-guided excavation system using Leica SmartNet correction, providing centimeter-level precision and 3D project documentation in XYZ coordinates. The company also deploys specialized environmental equipment (environmental buckets with lids, bubble and silt curtains, Fibertex laying equipment) for contaminated sediment projects, and mobile pumping systems for disposal site emptying. The fleet's smallest vessel handles marinas at 160 m3/hour while the largest reaches 600-800 m3/hour with 19-meter dredging depth.

Revenue is generated through project-based contracts on a per-job quotation basis. DBB operates as a subcontractor to tier-one contractors (Per Aarsleff, CG Jensen, Rohde Nielsen, MT Højgaard, Boskalis-Van Oord) on large port and coastal infrastructure projects, as a consortium partner handling all underwater work, or directly as prime contractor for smaller ports and municipalities. Marketing is primarily reputation-driven, with the company's stated philosophy that "the best advertising is a well-executed job." The reference portfolio spans 40+ documented projects across Denmark, Germany, Poland, and Lithuania between 2016 and 2024.

Pricing is quote-based and determined by project scope, vessel requirements, and duration. The company works as a subcontractor to main contractors, as a consortium partner, or directly for ports and municipalities.
