Geocean: connecting sea and shore to deliver water and energy infrastructure

Marine projects designed around real site conditions No two marine projects are alike. Water depth, geology, sea conditions, environmental requirements and shoreline configuration all influence the engineering and installation strategy. Geocean therefore works with its clients from the earliest stages of a project. Feasibility studies, geotechnical and geophysical surveys, route definition, engineering, procurement, logistics, construction and marine installation are considered as part...

VINCI Environmental Days 2026: making environmental thinking part of the way GEOCEAN delivers projects

Learning through experience The principle behind the Green Escape was straightforward: place participants in situations inspired by challenges encountered on construction projects and ask them to agree on the most responsible solution. Teams explored several issues directly related to the environmental impacts of construction activities: responsible concrete; reuse of excavated materials and other resources; waste management; circular economy principles; more efficient use of resources. One guiding principle ran...

Offshore Workplace Well-being

WHY WELL-BEING AT SEA IS A CHALLENGE IN ITS OWN RIGHT On Geocean’s maritime and offshore worksites, exposure to heat-related risks is not a theoretical issue. It is measured by hours spent outdoors, by perceived temperatures on overheated metal decks, and by accumulated fatigue under continuous solar radiation. During the summer, some work areas can reach 48-50°C in the shade. Under such...

LEG@SEA: GEOCEAN’S KEY RECOMMENDATIONS FOR A MORE SUSTAINABLE OFFSHORE INDUSTRY

BIOFUELS: CONCRETE SOLUTIONS TO REDUCE EMISSIONS Geocean actively recommends the use of advanced biofuels (HVO100, UCOME…) to power its base camps and naval operations. 🎯 Goal: up to 80% reduction in CO₂ emissions compared to fossil diesel. Key points: Prioritize fuels derived from waste over food crops (avoid Type I). Anticipate engine compatibility and storage conditions. Incorporate potential additional costs into tenders. These offshore biofuel solutions, such...
