Total transport and installation solutions
With unparalleled transport and single-lift and capabilities, Pioneering Spirit is reshaping offshore installation, providing a unique solution for the largest, heaviest offshore structures.
With Pioneering Spirit, Allseas is at the forefront of both traditional and renewable energy markets, setting new industry benchmarks. The vessel’s sheer size and lift capacity allow it to transport and install entire offshore platforms -topsides and jackets- up to 60,000 and 20,000 tonnes respectively, revolutionising the speed and safety of offshore development.
Our dedicated engineering teams work closely with clients to develop tailored transport and installation (T&I) solutions, allowing operators to move quickly from concept to operation, delivering energy faster and more sustainably.

Delivering value and opportunity
Pioneering Spirit streamlines field development by enabling single-lift installation of massive topsides and jackets, reducing offshore hook-up time and minimising costs.
The vessel’s unique single-lift, motion-compensation technology, and advanced dynamic positioning ensure high accuracy, while its size guarantees year-round workability in even the most hostile environments. This creates a faster, more efficient pathway for energy developments, helping operators meet project goals on schedule and within budget.
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.

As converter stations grow in size to support ambitious offshore wind targets in countries like the Netherlands and Germany, Pioneering Spirit’s capacity and versatility are ideally suited to meet these demands.
With T&I agreements stretching over a decade, and projects poised to deliver over 30 gigawatts of clean energy to power millions of homes and businesses across Europe, Allseas has firmly established itself as a leading force in the rapidly expanding offshore wind industry.
From offshore pipelaying to installing and removing offshore structures, Allseas excels in the design and execution of large and complex offshore projects worldwide. Activities include design, engineering, procurement, fabrication and project management.
