Mooring or berthing piles

Mooring or berthing piles often have a larger diameter than jetty piles and are of a more complex nature. Mooring or berthing piles are usually equipped with fendering, mooring features, bollards, ladders, handrails, electric and hydraulic supplies, and other auxiliaries. These piles are usually not connected to a jetty and stand alone in a river or in front of a jetty. Each project or even each pile requires a specific approach and access plan before we start the renovation of these piles.

Specific approach

For large diameter tubular piles, DZI’s are available for:

  • a full encapsulation of the pile (up to 3 m diameter) in which the repair and coating application are completed in one single operation,
  • a partial dewatering of the pile in which the repair is completed in multiple sections and handlings.

Once the DZI is installed, the full rehabilitation of the pile can begin such as cleaning, welding, gritblasting and coating application with Humidur® Coatings.
