Some 2,200 meters of quays in the naval port of Wilhelmshaven have been renewed. The harsh North Sea climate and bacteria that promote corrosion had severely damaged the east and west quays in the outer harbor of the port's 4th entrance. Therefore, while ensuring normal port operations, heavy equipment was used to drive a combined sheet pile wall from a jack-up platform in front of the existing quay wall. Special challenges were posed by peat lenses – soft soil layers that do not provide sufficient load-bearing capacity and made it necessary to opt for longer supporting piles. For the back anchoring, driven injection piles were installed. The new quays have a concrete abutment on the land side and an anti-corrosion coating combined with active cathodic corrosion protection on the water side (CCP system).
Over the past 15 years WTM Engineers has been involved in project planning, structural design, construction supervision, site construction supervision and production supervision of the port structure.
