Constructing 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.

Mammoet began with the proven design of its existing SK190 and SK350 cranes and explored how this design blueprint could provide the foundations for a new model with unprecedented lifting capacity and outreach; creating the SK6,000.

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. 

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.

Enabling floating wind at a commercial scale

Seeking higher winds and greater power yields, developers are building turbines bigger, taller, and heavier.  As hub heights rise higher, fewer and fewer of the world's cranes can install these huge components.

With so many large components involved, space on site will be at a premium, with many concurrent operations taking place and competition for port space from other sectors. This can raise site transportation costs, giving rise to hundreds of time-intensive, intricate movements during the installation phase.

The SK6,000 crane has been designed with exactly these types of challenges in mind. Capable of lifting 6,000t, it can lower many floating foundation designs directly into the water and assemble wind turbines from a single position. With a maximum hook height of over 175m and a reach of 144m, it can install turbines at towering heights - even when towers lie at the center of the floating foundation.

The crane design allows developers to consider more efficient launching methodologies for foundations weighing thousands of tonnes, setting new standards in efficiency, safety, and time to the first Megawatt.

FPSO and FLNG integration

Higher capacity land-based cranes have been developed to help keep pace with FPSO and FLNG module growth - among them Mammoet's PTC and SK range. The higher the crane capacity, the lower the number of modules needed.

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 meters. 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.

The SK6,000 means the lifting of topsides modules weighing more than 6,000t is now achievable with a land-based crane. Even where modules are lighter, the crane's longer outreach and stronger load moment mean both it and the hull must be moved far less often - meaning you can spend less time moving equipment around the site, and more time integrating.

'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'.
