The certified divers of PSOMAKARA Diving Services & Consulting Co cooperate efficiently and with high precision for underwater survey of underwater constructions and underwater survey of coastal structures. They have the experience and knowledge during the underwater survey to correctly identify information relevant to an underwater inspection and thus make recommendations for repairs and maintenance with detailed reports. The company is equipped to perform underwater survey of coastal structures and underwater survey of underwater constructions (bridges, dams, underwater tunnels, drilling rigs, floating docks, pipelines etc.) under adverse conditions, with poor visibility, high currents and great depths.
The reinforced concrete structures exposed to the marine environment are often damaged, caused by corrosion of the steel. The seawater causes damage to concrete and corrodes, due to the presence of chlorides, sulphates, oxygen and other harmful elements.
The detachment of the concrete coating has direct impact on the strength of the reinforced concrete. With the presence of cracks, seawater reaches easily the armament and eliminates the protective conditions created by the layer of oxides around the steel in the alkaline environment of concrete. In these conditions, corrosion of steel occurs and because of this considerable mechanical stresses are created which strain the concrete, which contribute to the further development of cracks, splitting the concrete cover and accelerate the corrosion process. For this reason it is necessary to periodically carry out underwater survey of coastal structures and underwater survey of underwater constructions , for predicting damage and maintenance.
PSOMAKARA Diving Services & Consulting Co undertakes underwater survey of coastal structures and underwater survey for underwater constructions and their maintenance, such as:
- Underwater survey-Underwater maintenance pipelines.
- Underwater survey-Underwater maintenance floating docks.
- Underwater survey-Underwater maintenance of dams.
- Underwater survey-Underwater maintenance rigs.
- Underwater survey-Underwater maintenance bridges.
- Underwater survey – maintenance of submarine underwater tunnels.
