Immersion Engineer


For the offshore activities in FLC Marine, we are looking for skilled and dedicated Immersion Engineer.

Immersion engineering is taking care of all calculations regarding tunnel elements float up (weight analysis, determine ballast concrete and water, longitudinal section forces, floating stability), transfers in basins and harbour (winch operations with or without vessel assistance), mooring of the tunnel elements, transport to offshore location, immersion (including but not limited to dynamic analyses) and the stability of the elements after immersion.

As an immersion engineer, you will participate in the team responsible for floating up and/or hoisting the concrete tunnel elements, equipping them in the port and then transporting and installing them at sea. In a first phase you will participate in the preparation of this crucial operation, by making ballast plans e.g.. In a second phase, you will be part of the operational team that does the immersion work, by going offshore and assist the Immersion Master by giving technical advice. This is what you are pre-pared to do in Denmark (full time or in 4-2 rotation).
