Posted October 1, 2018

The company will supply the LNG/diesel-electric propulsion system and the water injection dredging system for a new dredger which will operate at the Port of Bordeaux.

As previously reported, the construction of the L’Ostrea is a joint initiative between Atlantic Port of Bordeaux, the EIG Dragages Ports and the Socarenam shipyard, based in Boulogne-sur Mer. The vessel is said to be the first dual-fuel project in France (excluding LNG tankers).

The scope of the project covers the design and supply of the main panel for hybrid energy production, the main and auxiliary dual fuel/electric propulsion and an energy conversion system.

The two main propulsion assemblies will each include an electric motor with nominal power of 1,200 kW at 1,600 rpm. The bow thruster auxiliary propulsion system will comprise an electric motor with nominal power of 400kW at 1,500rpm. The two dredging pumps will each have power of 500kW.

The conversion system will convert the upstream 690V/60Hz energy to the downstream 400V/50Hz network and will be equipped with two 150kVA decoupling transformers.

The vessel will principally operate on marine LNG and will also have the capability to run on marine diesel oil (MDO).
