As part of its ongoing program to improve maritime access, the Port of Rouen, located on the strategic Seine axis between Paris and Le Havre, has launched a
project to modernize the Grand Aulnay wharf operated by Rubis Terminal, a European leader in the distribution of liquid energy products and the storage of bulk
liquids.

As part of this project, Balineau was awarded the contract to build six new mono-tubular dolphins, metal tubes anchored in the ground, for berthing and mooring ships. To achieve this, Balineau had to mobilize exceptional ramming equipment. The tubes, weighing 82 tonnes, 34.5 m long and 2200 mm in diameter, were driven using a crane barge and an IHC S250 hydraulic hammer capable of mobilizing energy up to 250 kJ.

These new dolphins will increase the berthing and loading/unloading capacities of the berth. From now on, “long range” ships including tankers and chemical tankers of 230 m in length and a loading capacity of around 53,500 tonnes, will be able to be accommodated.
