Züblin and Heinrich Hirdes working in joint venture have secured a €120M (£93.5M) contract to construct a new offshore terminal at Bremerhaven, Germany.
Central to the deal is construction of a 500m long quay which will be built using an innovative approach, according to client Bremenports.
“The quay will not be built as a conventional combined sheet piling wall consisting of king piles and intermediary piles,” said Bremenports managing director Robert Howe. “Instead, the king piles will be replaced in this project with 159 steel tubular piles.”
The 1,820mm piles will be between 30 and 39m long and weigh up to 5,000t. The intermediary piles will weigh up to 750t and the anchor piles will measure up to 51m.
The project also includes construction of the terminal ground slab, terminal access roads and retrofitting of levees.
The foundation piles for the heavy-duty slabs consist of around 630 cast in-situ concrete piles with a total length of about 16km. Construction of the approximately 25ha terminal will require the pumping of about 2.6.Mm³ of sand from the river Weser. The sand will be dredged by hopper dredgers as part of the usual Weser dredging works. Construction of the port facility will also involve pouring about 18,600m³ of concrete.
Enabling works have started on site and the terminal is expected to be handed over to the client in late 2018 or early 2019.
