Reinforcing existing seawall project in Otaru Port

Renovation

The project is to modify a quay wall that aimed to bring a 150,000-ton cruise ship to shore at Otaru Port. BB Anchor was adopted as a soil retaining support for underwater excavation carried out to improve the quay wall.

There are two reasons for adopting the BB Anchor, first is because the excavation area was located nearby the warehouse, and second, the deep accumulation of soft ground makes it difficult to secure the bearing layer for conventional ground anchors.

Due to these background, BB Anchor was adopted because it is a bearing pressure type ground anchor that can provide significant bearing capacity even in soft ground.
