From factory to foundation

Efficiency is key with any wind farm project, and Mammoet offers clients an unbroken logistical chain optimized to lower costs and enhance safety at every stage.

The ever-increasing scale of turbine components brings unique challenges for wind farm constructors and operators. Suitable locations for turbines are not necessarily where local infrastructure can accommodate the passage of large and heavy components. This combines with the windy conditions essential for high yields but that can limit time windows for installation work. Furthermore, the nature of wind farms, with their coverage of turbines across vast areas, leads to spread out installation and maintenance areas. As a result, for onshore, near shore or offshore wind facilities, optimization of project logistics can become essential for a cost-effective operation.

Onshore logistics

For onshore wind farms, there is the challenge of overland transport of large and heavy tower sections, nacelles, generators and rotor blades from the original manufacturing facilities all the way to site for installation. These are often at remote locations making the route analysis crucial. In hilly areas, steep inclines may determine the requirement of specific transport equipment and additional securing of loads. Many wind farm locations may require significant civil works to build access roads and installation pads, which can prove time-consuming and costly. Mammoet can help reduce these costs by optimizing routes through extensive transport studies and the creation of an integrated logistics plan.

Nearshore and offshore logistics

The construction of nearshore and offshore wind farms combines the installation of increasingly large and heavy components with the high costs of offshore installation. Additionally, this environment has important safety considerations. Mammoet’s focus on a safe logistical operation, alongside our specialized engineering capabilities, enables us to find the right approach for every offshore facility. This has included the world’s first floating wind farm and the transport of both the heaviest tower sections and the longest rotor blades ever deployed, using customized frames for their safe and secure transport.

To keep costs under control the logistical chain needs to ensure maximum utilization of offshore installation vessels. Different components need to be collected, stored, loaded and transported for installation at sea. Combining these activities and creating efficient component packages means construction time and costs can be significantly reduced.

Greater efficiency for our clients

With a history dating back over 200 years, and extensive experience in heavy lifting and transport across energy sectors and around the globe, Mammoet has built up a logistical knowledge bank that is second to none. All of this know-how, paired with our experience of the practicalities of moving and erecting some of the world’s largest wind turbine generators, means that we have all the core competencies required to carry out logistical work on wind farm projects large and small.

Mammoet’s heavy lifting and transport engineers begin any move by making a detailed logistical plan. Factors include the size and weight of the components being hauled, equipment required, interfaces between modes of transport, border crossings and the set-down point at destination. Route planning will be carried out and potential bottlenecks and contingencies planned for, with safety a key consideration throughout.

Our service stretches from fabrication site to the wind turbine generator’s foundations in an efficient, optimized and unbroken logistics chain. The complexities of moving large and heavy items are managed with specialist skill and insight, and we are able to tailor solutions for onshore, shallow nearshore and deep-sea offshore development.

Wind power construction projects face the challenges of remote locations and increasingly large components. Mammoet’s efficient logistics and installation procedures optimize the supply chain, bringing deadlines forward.

To benefit from greater power output, new wind farm installations are deploying hardware that is larger than ever before. However, as components increase in size and weight, and as wind farms are installed in more remote regions of the planet, their operators face increasing construction challenges. Windy conditions and inclement weather on site, the risks of operations at sea, and the limitations of local roads and bridges are just a few of the considerations faced by new wind farm projects.

Specialized heavy lifting and transport equipment and skilled teams, capable of transporting and installing new wind turbine generators, are essential requirements for realizing a safe and efficient construction process. With the latest high mega-wattage nacelles, tower sections weighing over 200 tons, and rotor blades approaching 100 meters in length, specialized cranes and trailer equipment are standard requirements for wind farm construction. However, assembling the necessary equipment is only part of the formula. With core competencies in planning, logistics and engineering – as well as extensive experience in wind farm construction techniques – Mammoet supports wind farm clients by managing all the heavy lifting and transport requirements.

An integrated approach

Many wind power construction projects involve different contractors for shipping, onshore transport, crane operations and mechanical and electrical installation. Outsourcing to different contractors and subcontractors means a complex supply chain for the wind farm operator. It leads to communication difficulties and can compromise site safety. Optimizing the scope of their various tasks and schedules is complex and requires management time. Failure to do so can result in delays and cost overruns.

By taking advantage of Mammoet’s integrated approach, wind farm construction projects benefit from greater efficiency across all heavy lifting and transport requirements. A single point of contact and coordination streamlines communication and allows for the alignment of activities and installation schedules — maximizing efficiency, safety and cost-effectiveness — potentially saving time across the construction process.

Maximizing output

Once a new wind farm is up and running, investors may wish to expand the facility, increasing power output and maximizing the area’s wind potential to optimize their return on investment. As the industry seeks greater economies of scale, new generators are added to existing wind farms and the wind turbine generators themselves are built from increasingly large components. A partner like Mammoet is essential for efficient expansions, both in terms of transporting components with a specialized fleet of equipment, and the installation experience of our teams. Mammoet has optimized the process for some of the world’s largest wind farm expansions, and has set world records by moving the longest rotor blades and the heaviest tower sections.

In onshore settings, expansions have been carried out in some extremely remote locations, where challenges have included the unpredictable climate, narrow roads, steep inclines and local environmental protection measures. In near shore and offshore settings, the inherent challenges of working on water and the sheer size of the components makes specialized heavy lifting equipment and transport expertise essential. Mammoet’s experience dates back to the very start of the wind power industry and we have worked with our clients, as the industry has evolved, to optimize upgrade processes, safely carrying out expansions on schedule, within budget, so our clients can maintain efficient output.

Sustainability through precision

Mammoet’s heavy lifting and transport expertise supports renewable power suppliers to improve project efficiency, safely bringing new power online and reducing costs per megawatt.

Renewable energy projects include a mix of both established and fast-developing technologies. These include hydroelectricity, wind power, tidal energy, wave energy and concentrated solar power. Each system has its own unique construction challenges and opportunities to increase the efficiency and overall cost-effectiveness of a project by planning for scale and modularization. Reducing construction and installation time shortens time to market, bringing sustainable power sources online more swiftly and bringing forward returns on investment. 

For newer or less established forms of renewable technology, proving the potential of the design helps attract investment –taking projects to the next level. After proof of concept, the design needs to be adapted for large-scale applications. In many renewable power plant projects, large and heavy items including turbines, generators or entire pre-assembled structures housing all components are installed. Because new power generation technologies are involved, operations often take place in unusual circumstances with unique challenges. For example, during one recent state-of-the-art tidal power project off the coast of the Netherlands, engineers had a 90-minute window on a specific day in September in which to slide a 50-meter long tidal turbine structure into place — while safely managing the impacts of tides, currents, wind and season.

Mammoet’s skilled heavy lifting and transport engineers can unlock opportunities for efficiency right from the start. Our creative engineering and precision planning optimize the transport and installation of renewable facilities, and their components, while minimizing risks, costs and construction time for our client. Mammoet has built strong partnerships in the renewable energy sector. No matter what kind of challenges are posed by renewable technologies, collaborating early in a project helps move deadlines forward, reducing costs and ensuring an overall safe, smooth and on-time execution of the project.

Harvesting hydropower

Hydropower is nearly as widely used as wind-generated power but the location of the hydroelectric power plants often poses the most complicated challenges for heavy lifting and transport operations. In many instances, large and heavy components such as water turbines, generators and transformers, need to be transported down steep and narrow tunnels to reach the powerhouse and, once inside, space for maneuvering and installing is often highly restricted.

Careful planning and flawless execution skills are of great importance to ensure components are delivered and installed underground safely and on time, thus speeding up time-to-market of the renewable power plant.

Tidal power

Tidal and wave power are forms of hydropower that are still in the early stages of development but the technology is advancing rapidly. Each type of design has its unique specifications and requirements for installation.

Early involvement of our specialized engineers and planning team is crucial to develop and execute a safe, efficient and cost-effective logistics plan that takes into account environmental conditions such as strong currents and rough weather. During execution, our team brings all their ingenuity and the right toolbox of equipment to the project so that they can respond effectively to any unforeseen events that could disrupt the critical path.

Concentrated solar power

Solar power is another fast-developing form of renewable energy with interesting opportunities for increasing yields and reducing costs through scale. Concentrated solar power (CSP) plants use molten salt technology, which can operate alone or as part of an integrated solar combined cycle (ISCC) power plant. To increase efficiency and harvest more energy, large mirror arrays are used to reflect and concentrate sunbeams onto the receiver unit. Both the mirrors and receiver units are growing bigger and heavier, requiring lifting expertise for safe installation at increasing heights. Strong winds at these heights can seriously jeopardize safety, limit productivity and negatively impact the schedule.

Investing time at the early planning and design stages means that we can help develop the most efficient construction approach, which could range from stick-built on location to lifting the preassembled receiver unit into place. Everything we undertake at Mammoet is always focused on how we can increase the safety, efficiency and cost-effectiveness of the entire project for our client.
