Case Study: Leading Cable-Laying Company achieves €4M savings and safer offshore operations with DTN weather forecasting

Leading Cable-Laying Company Made Tough Call with Accurate Weather Data

Leading Cable-Laying Company, a world-leading cable systems firm working in the North Sea, faced an unexpected shift in wind speed and direction during a German Bight cable-laying operation that put crew safety and an in-water cable at risk. Only the DTN weather forecasting service — supported by its weather room, meteorological consultation, and proprietary DTN models — predicted the sudden change, creating a critical decision point for the operations team.

Relying on DTN’s forecast and expert guidance, the team decided to cut the cable; winds later exceeded workability thresholds for more than three hours, validating the choice. By trusting DTN’s data the company avoided a potential cable snap that would have added about 15 days to the project and roughly €4 million in reconnection costs, while protecting personnel and minimizing disruption.
