AbstractFor the new breakwater in Swinoujscie, Poland, Xbloc has been used as breakwater armour layer. The local conditions in this region with low temperatures in the winter season and poor under water visibility required some innovative solutions to design and build this impressive marine structure. The project was the first Xbloc application where sea ice is expected. An assessment was therefore made of the expected ice loads and possible damage mechanisms due to these ice loads. It was concluded that the chance of damage to the armour layer as a whole was minimal, but an increased concrete strength was applied to deal with the ice forces on individual units. The concrete mix and the production process were adjusted as a result of the low winter temperatures. Furthermore the echoscope® realtime sonar was used to guide the underwater placement in poor visibility conditions. In this paper design and construction aspects are presented of the Swinoujscie breakwater.
