Sleipnir Semi-Submersible Crane Vessel Atlantic Transit Optimization

completed

Heerema Marine Contractors shortened the North Atlantic transit of its semi-submersible crane vessel Sleipnir by 2.5 days using a data-driven voyage optimization pilot with French ocean intelligence company Amphitrite. The optimization reduced sailing distance by 240 nautical miles and cut CO₂ emissions by up to 18%, while maintaining higher average speeds without increasing fuel consumption. The pilot used vessel-specific performance modeling combined with high-resolution ocean current, wave, and weather intelligence to optimize the route from Rotterdam to New York for offshore wind substation installation.
