±2 days
forecast accuracy on a real 7-month construction campaign
Plan and optimise offshore wind farm construction and operations in a virtual environment. ForeCoast® Marine simulates entire construction and O&M campaigns using historical weather constraints and operational constraints, drawn from global metocean data spanning many years.
Weather delays are one of the biggest risks in offshore wind campaigns, driving up costs and causing missed milestones.
ForeCoast® Marine is a web-based tool that helps developers, consultants and O&M managers plan more effectively, identify campaign bottlenecks, minimise downtime, and optimise project delivery across both construction and O&M phases. By leveraging metocean data, it delivers significant CAPEX and OPEX savings.
Proven accuracy, tested on real projects
ForeCoast® Marine’s forecasts have been validated against real, completed campaigns, including a 7-month construction programme where its campaign duration prediction was within 2 days of its actual finish date.
Why ForeCoast® Marine?

Optimised timing & resources
Identify bottlenecks and potential downtime earlier to optimise vessel, personnel and resource allocation.

Reduce risk & cost
Reduce costly downtime and delays with quantified simulation results.
Lower environmental impact
Efficient campaign planning and reduced vessel time help meet sustainability goals.
Enhanced transparency
Clear simulation outputs and risk metrics demonstrate proactive risk management.
Flexible modelling for real project conditions
Every offshore wind and marine campaign carries different risks – from stress-testing a new product concept, to comparing installation strategies, understanding weather-driven bottlenecks, or modelling how an O&M strategy will perform over the long term. ForeCoast® Marine lets teams model a campaign around the specific questions that matter for their project, using historical metocean data from hindcast models or on-site observations.
Because it tests campaigns against historical weather data rather than a single assumed scenario, ForeCoast® Marine surfaces the bottlenecks, weather sensitivities and cost drivers that a simplified, average-year assessment can miss.
From concept validation to installation and O&M
ForeCoast® Marine supports decision-making:
Early concept validation – test how installation and O&M campaigns for a new foundation, floater or installation method would play out under real-world weather conditions, before committing to physical prototypes or sea trials.
Installation planning – simulate full construction campaigns, from port-to-vessel transfer through to offshore works and return to port, to compare strategies and manage weather window predictions.
Operations & maintenance – evaluate O&M strategies and understand the downtime impact of maintenance events across the project’s operational lifetime.
By making this kind of testing possible earlier and more convenient than physical trials, ForeCoast® Marine helps teams understand the real-world implications of design and strategy decisions while there is still time to act on them.
Who is it for?

Optimisation backed by real-world offshore wind engineering expertise
ForeCoast® Marine has been developed by experienced offshore wind engineers and project developers, ensuring the software reflects real project constraints, practical logistics and the realities of delivering offshore wind and marine projects at scale.
This means the modelling isn’t purely theoretical. It’s grounded in real-world offshore wind engineering judgement, helping teams explore realistic, buildable strategies and reduce the risk of late-stage surprises.
ForeCoast® Marine is used across real projects and research programmes, including by Tokyo Electric Power Company (TEPCO), Marine Power Systems, Walker Subsea, and the University of Bristol working with Wood Thilsted on the Buoyant Guyed Column (BGC) foundation concept.
