AT THE HEART OF MARITIME INFRASTRUCTURES
We operate in maritime and port environments to carry out reliable and secure technical operations on all types of coastal and offshore infrastructures.
INTERVENE WHERE LAND AND SEA MEET
SIDON mobilizes its technical and human expertise to intervene on maritime and port infrastructures, both in coastal and offshore zones. With our expertise in the marine environment, we carry out complex operations, respecting safety, reliability, and port coordination requirements.
Interventions on all types of maritime structures
Our teams specialize in interventions on strategic coastal and offshore infrastructures, including:
Quays, jetties, dikes, breakwaters, and piers
Coastal protection structures and crossing works
Marine outfalls, water intake and discharge points, outfalls
Offshore structures: platforms, docks, buoys, mooring systems
Civil, military, or industrial port installations
SIDON operates in the construction, maintenance, reinforcement, and emergency repair phases on structures exposed to maritime constraints.
TECHNICAL EXPERTISE TAILORED TO MARINE ENVIRONMENTS
The maritime environment requires specific skills. Our professional divers and technicians are trained to operate at sea and on the coastline, including in hyperbaric conditions. We perform the following operations:
Underwater works: cutting, welding, concreting, inspection
Installation and sealing of underwater structures or protective elements
Emergency repairs on submerged structures or those damaged by weather conditions
Maintenance of port structures, desilting, targeted dredging
Non-destructive testing (NDT) and diagnostics of submerged structures
Our equipment is designed to withstand harsh maritime conditions: swell, salinity, strong currents, and deep-water zones.
COORDINATION WITH PORT AND MARITIME STAKEHOLDERS
SIDON works closely with port authorities, coastal communities, maritime engineering firms, and specialized public works companies.
Our ability to adapt to maritime traffic constraints, regulated zones, or Natura 2000 areas enables us to carry out effective interventions that comply with local regulations.
SAFETY, ENVIRONMENT, AND PERFORMANCE
All our maritime projects incorporate a rigorous QHSE approach, including the management of risks related to the marine environment. We place great emphasis on protecting sensitive environments, while ensuring the safety of workers and the technical performance of the solutions implemented.
