SOA Category OG7
Qualification for maritime works, dredging, and related coastal infrastructure
The OG7 category of the SOA certification system covers maritime works and dredging activities—key infrastructures for ports, coastlines, and water‑related logistics. These projects are highly complex and require expertise in maritime engineering, coastal protection, and geotechnics, as well as the use of specialized equipment. OG7 is therefore a strategic qualification for companies operating in port logistics, environmental protection, and coastal defense, certifying their technical and organizational suitability for high‑value, high‑impact public works.
Ports, breakwaters adn coastal defense at the core of OG7
The OG7 category applies to all maritime and port works essential for coastal infrastructure, harbors, and navigable basins. Key areas include:
- Commercial port infrastructures: construction and expansion of merchant ports, berths, equipped quays, logistic platforms, and breakwaters. Typical examples include container terminals with dredged seabeds for deep‑draft vessels.
- Tourist marinas and naval berthing structures: yacht harbors, floating docks, breakwaters, and passenger terminals. Naval bases and shipyards also fall under OG7.
- Coastal defense works: protection of shorelines through breakwaters, groynes, and other structures designed to dissipate wave energy and prevent erosion.
- Dredging and maritime basins: seabed excavation to maintain or increase navigational depth and the construction of dry docks, basins, or expansion areas.
- Underwater pipelines and submerged works: installation of underwater aqueducts, gas pipelines, outfalls, and other works in marine, lagoon, or lake environments.
Related SOA categories that integrate with OG7
OG7 works frequently integrate with other SOA categories, especially in complex maritime projects combining structures, networks, and specialized equipment:
- OG6 – Water and utility networks: OG6 covers land‑based pipelines and networks for water or gas, while OG7 covers point‑based works in marine settings. In land‑to‑sea projects (e.g., an aqueduct with a marine outfall), both categories are required: OG6 on land, OG7 in water.
- OG8 – River and hydraulic defense works: OG8 applies to river and inland hydraulic works, while OG7 applies to coastal and maritime environments. In transitional zones such as river mouths or lagoons, both may apply.
- OS21 – Special structural works: often required in OG7 tenders involving complex foundations such as piles, diaphragm walls, anchors, or jet‑grouting.
- OS32 – Timber structures: required for large wooden piers or walkways in tourist marinas.
- Other integrated categories: OG1 (port buildings), OG3 (internal roadworks), OS30 (electrical installations), OG11 (integrated systems).
FAQ
SOA Category OG7
OG7 is a strategic category for national competitiveness and infrastructure development: it enables modern port construction, coastal‑protection works, and the reinforcement of maritime connections with global trade routes.
For maritime‑sector companies, the SOA OG7 qualification is essential—not only mandatory for public contracts, but also a strong indicator of technical competence and reliability in complex marine environments.
