Building bigger and faster

To increase the efficiency of production, FPSO and FLNG modules are growing larger and heavier. Truly immense structures, these push the boundaries of what is possible to lift using a land-based crane. So, Mammoet created the SK6,000.

Reaching the limit

Constructing FPSO and FLNG modules onshore has allowed EPCs to expedite project schedules and increase cost-effectiveness. As these components grow, so does their efficiency – but also the challenge of their construction.

The sheer size of these modules lies on the edge of what modern lifting technology can achieve - regularly breaking the 3,000t barrier and tens of thousands of cubic metres.

Given the loads involved, it can also be difficult to find adequate lifting technology close to the project site. This can narrow the execution choices available during each project’s planning stage, and the percentage of the project that can be executed locally.

And with so many large modules involved space on site is also at a premium, with many concurrent operations taking place. This could raise site transportation costs, giving rise to hundreds of time-intensive, intricate movements during the installation phase.

Constructing FPSO

As our customers strive for greater and greater efficiencies, both in terms of construction and production, the capacity of land-based cranes becomes a significant limiting factor when developing the FPSO modularization strategy. With the innovation of the SK6,000 crane, our customers can think bigger than ever before; pushing modules beyond the 3,000t and even 4,000 barriers.

As FPSO designs scale-up, no only are module designs growing larger and heavier, but flare towers are also becoming taller than ever before. With our SK6,000, we can install flare towers of up to 1,500t and 150m in height in a single piece.

With its long outreach, small minimum footprint and relatively small site impact, the SK6,000 greatly reduces the topside integration time. Needless to say, with larger building blocks you spend less time connecting and testing, and more time producing.

Raising the bar

The SK6,000 allows EPCs to build bigger than ever before, offering a maximum lift capacity of up to 6,000t. Its proven design allows modules to be lifted directly onto the hull – without a requirement to rotate either the modules on land, or the ship.

Its unique design, consisting of a centralized ballast, means that there is no need to install a full ring track. This frees up site space by up to 45%, allowing operations around the crane to continue and the FPSO to launch faster.

As the SK6,000 is containerized and can be assembled quickly on site, it can deliver heavy lift capability to wherever it is needed. This provides greater flexibility in where and how projects are completed.

The SK6,000 allows EPCs to consider construction methodologies involving heavier components than ever before, stretching beyond 4,000t. This allows new standards to be set in efficiency, safety, and time to production.
