Driving offshore renewable energy

Our transport and installation (T&I) capability is a game-changer for offshore wind operators. Leveraging our pioneering single-lift technology, we tailor rapid, efficient and sustainable solutions for transporting and installing massive offshore substations.

Building a resilient and diverse energy sector

Our extensive experience in heavy lift and subsea construction equips us to install all types of offshore infrastructure across diverse environments and water depths. With a deep commitment to a sustainable and diversified energy future, we are set to lead in offshore wind, enhancing efficiency and expanding renewable energy capacity.

Creative concepts in offshore wind

Pioneering Spirit is a game-changer for fast-tracking the installation of supersized converter platforms, a critical component for next-generation offshore grids. Recent projects, such as DolWin6, underscore our capability to handle the largest offshore wind structures safely and efficiently, making us a top choice for major European wind initiatives.

Next-generation turbine installation

Pioneering Spirit will be instrumental in installing the next generation of massive turbines, with turbine capacities projected to grow from 10 MW to as much as 20 MW over the coming decade. As demand increases across North America, Europe and Asia, we will continue to deliver innovative solutions for large-scale turbine installation, accelerating the industry's ability to meet renewable energy targets.

Production line mindset

Our engineering teams are developing innovative concepts to adapt single-lift capabilities for large turbine installations. By applying a ‘production line’ mindset inspired by pipelay operations, we are creating new methods to install turbines faster and more cost-effectively than traditional vessels. This approach could halve standard installation times, providing unmatched efficiency for developers.

Year-round high workability

The size and versatility of Pioneering Spirit allow for greater lift and transport capacity, reducing installation timeframes while maximising operational flexibility – even in challenging winter conditions. This high workability means fewer weather delays, helping projects stay on track and enabling clients to realise their renewable energy goals sooner.
