Piling and mooring systems
If you have decided to install a floating pontoon, you should consider the best mooring system for the conditions of your marina. The depth, seabed and proximity of the dock are different for each project and you will benefit from the services of our full team, who will study your proposal and suggest the best method.
Piling systems
Piling is carried out using large steel tubes (piles) that are vertically attached to the seabed. The piles are driven into the soil and anchored to the dock by a ring with rollers that allow the floating structure to rise and fall with the tide. The process of inserting piles into the soil is known as pile driving.
AISTER has over 30 years of experience driving piles in all sorts of soils with our pile drivers. On soft soils, we use a hammer up to 2,000 kg to drive the pile until withstanding pull tests of up to 10 tonnes, while on harder soils like rock, piles are driven using trepans to break the stone.
5 pile drivers
One of our most challenging projects was the Ocean Village Marina in Gibraltar, where we were the only company able to drive the pile into the rock.
We have five pile drivers, fitted with all the necessary equipment to drive piles into any soil, including sand, stone and mud. Our pile system involves the precision driving of piles of up to 800 mm diameter using the hammers and trepans of our pile drivers.
Mooring systems
- Rods: This system is used to attach docks parallel to the dock via aluminium parts called rods that maintain the distance between the dock and the floating pontoon. The system is also useful for withstanding the tensile and compressive stress caused by currents, waves and wind on ships moored to the pontoon. AISTER has super-reinforced rods that can be used for mooring large ships.
- H beams: This attachment system uses steel H beams as rails fixed to the dock using stainless steel anchors and to the dock using corrosion-resistant aluminium rings. The size and length of the beam depends on the tidal range, the installation site and the type of ship to be berthed.
- Concrete deadmen: This system uses flat concrete blocks that are deposited on the seabed with chains that connect them to the floating dock. The weight and size of the concrete deadmen depends on the project.
- Seaflex: An elastic attachment system for concrete deadmen that keeps the tension of the rubber components constant to reduce movement of the dock during the tidal range.
