Shortening the critical path in petrochemical construction projects

Successful heavy lifting and transport operations at refinery or chemical plant construction sites begin with careful planning by Mammoet’s specialists to define the most efficient logistical and installation approach.

Involving Mammoet’s engineered heavy lifting and transport specialists early in the planning and design stage of a petrochemical construction project is crucial. With their expertise, the refinery or chemical plant’s critical path can be shortened through reliable planning, improvement of efficiency and the reduction of costs. 

We use our experience and in-depth knowledge of heavy lifting and transport equipment to consider the three fundamental operational elements of any project: construction approach, transportability and productivity. By understanding the size and weight limitations of the components; how to lift, transport and install them; and how to optimize the heavy lifting and transport process, huge benefits can be realized in refinery and chemical plant construction.

Construction

The construction approach and installation sequence of components and modules is the first consideration. Different construction methods – ranging from ‘stick-built’ on location to offsite modular construction – offer specific opportunities to optimize the construction efficiency of a refinery or chemical plant. The maximum allowable sizes and weights of elements have a defining influence on realizing these efficiency gains.

Logistical considerations such as the positioning of saddles and lifting points can be defined at an early stage and will affect the structural design of oversized and heavy items, such as catalytic crackers, coke drums, reactors and modules. This may depend on what transport configuration, installation approach and equipment will be most efficient and practical for the plant. Considering such factors early during the planning and design stage will help ensure a smooth logistical and installation process when engineered heavy lifting and transport equipment is deployed.

Transportability

Many of the logistical limitations for transporting oversized and heavy items are defined by the location of the refinery or chemical plant construction site. Transporting components and modules from the manufacturing facility to the construction site might require an integrated chain of logistical activities with multiple handover points between different modes of transportation.

If not properly planned and managed, these handovers can have a huge impact on cost and timeline. The most efficient routes need to be determined for all items and ways must be found to deal with infrastructural bottlenecks, while complying with all local rules and regulations. The overall logistics plan needs to address each change in transportation mode in detail to ensure the components arrive in sequence for installation.

Productivity

Further optimization of the construction schedule can be realized by analyzing all horizontal and vertical moves across the refinery or chemical plant site to determine the right amount and type of lifting equipment and resources are on hand. By optimizing equipment and resource utilization, engineered heavy lifting and transport experts can make a project more cost effective. For example, in some cases one large crane can replace multiple smaller cranes and optimize utilization schedules while minimizing mobilization and demobilization activities.

Preparing for success

Connecting construction approach, transportability and productivity, and finding the optimum relationship between them, requires early collaboration between construction engineers and Mammoet’s professionals. Potential transport and installation bottlenecks can be identified early and creative engineering solutions applied to overcome them. Our professionals can undertake a thorough analysis of construction methods and find the most efficient dimensions and weights of components and modules for chemical plant or refinery construction. This analysis takes into account the best transport routes, on-site logistical possibilities and the necessary amount and type of heavy lifting and transport equipment needed for installation. These different methods are then assessed for their risks and cost/benefit implications. Through early collaboration, joined-up planning can move deadlines forward, reduce costs and ensure an overall smooth, safe and on-time execution of the petrochemical construction project.

Logistics solutions for construction efficiency

The right logistical process is crucial for the critical path of a refinery construction or upgrade project. Mammoet’s expertise in heavy lifting and transport ensures all components arrive safely on site in the correct order, at the right time.

Mammoet’s engineered heavy lifting and transport specialists play a defining role when it comes to the logistical aspects of transporting oversized and heavy items from manufacturing facilities to petrochemical plant construction sites around the world. Where plants lie in remote locations in extremes of cold or heat, this challenge is intensified.  

With productivity and efficiency at the top of the agenda, refineries, LNG and chemical plants are being built at even larger scales. To maximize construction efficiency, oversized and heavy components and modules are becoming the norm. This requires heavy lifting and transport specialists like Mammoet to constantly push the boundaries of what is logistically possible. The challenge is to safely transport pre-constructed components such as reactors, catalytic crackers, distillation towers, coke drums, pipe racks – sometimes pre-fabricated modules weighing thousands of tonnes - quickly and efficiently to sites that may be remotely situated or in hard to access locations. 

Overcoming logistical bottlenecks

By carrying out route studies, Mammoet professionals can identify infrastructure limitations between manufacturing facilities and construction sites that could complicate the transportation of oversized and heavy items. Tunnels or bridges may be too low, bridges too weak or road gradients too steep. Some areas may present specific risks, for instance when crossing remote polar or desert environments to reach new refinery and chemical plant locations.

Many risks can be avoided or mitigated by developing alternative transport options – either to bypass bottlenecks, overcome them using engineered solutions or even unlock an entirely new route. Mammoet resolves logistical challenges by finding the optimum route and overcoming obstacles by designing solutions such as road and bridge reinforcements or temporary bridges and jetties.

Stepping from a creative logistical solution to a flawless execution requires engineering skills, heavy lifting and transport expertise, and a comprehensive fleet of equipment suitable for the loads. The end result is an optimal logistical chain for all individual oversized and heavy items in alignment with the overall project plan.

Factory-to-foundation logistics

Along the logistical chain, land and water-based transport solutions may be used, often involving different operators with their own separate transport plans, equipment and workforces. A fragmented logistical chain can lead to delays and additional costs, such as demurrage charges, when transporting oversized and heavy items. With Mammoet your project benefits from our integrated approach, and our professionals will sequence and manage all logistical activity for maximum efficiency.

Mammoet’s factory-to-foundation (FtF) service brings the advantage of working with one specialist in charge of all the logistics for oversized and heavy items. This starts by picking up the reactor, distillation tower, coke drum or module at its manufacturing site and ends with installation at the construction site. With us managing the entire logistical supply chain it is possible to optimize operations, avoid delays and increase the efficiency of transport by road, water and rail. This includes efficiently processing required documentation for border crossings and obtaining abnormal load permits.

Our FtF service ultimately delivers a tailor-made and optimized logistical chain, minimizes the number of handover points, and ensures smooth handling between different modes of transport. This reduces or eliminates demurrage charges and ensures all components and modules arrive on time and in the right order for on-site installation.

Eliminating risks for a smooth logistical process

In an ideal logistics scenario, components and modules would roll off the ships as they arrive for direct, on-site installation, avoiding double handling. In reality, however, modules are often shifted around construction sites up to a dozen times prior to being finally installed. This is because different contractors work according to their own plans and schedules in an un-coordinated fashion. It almost always leads to budget overruns.

Taking an integrated approach for all engineered heavy lifting and transport activities across the project contributes to greater efficiency, cost-effectiveness and safety. Mammoet has the experience and expertise to effectively deal with all challenges when transporting oversized and heavy items from factory to foundation, ensuring safe and on-time arrival.

Mammoet’s engineered heavy lifting and transport specialists play a defining role when it comes to the logistical aspects of transporting oversized and heavy items from manufacturing facilities to petrochemical plant construction sites around the world. Its equipment fleet – the world’s largest – means it can scale from movements of a single reactor to and entire LNG construction projects with modules weighing hundreds of thousands of tonnes, cumulatively.  

On top of flawless and safe execution, a petrochemical construction team needs expertise, ingenuity and the right toolbox of heavy lifting equipment to manage the critical path. The scale of refinery and chemical plant construction projects has led to increasingly complex operations. This in turn creates new demands for on-site lifting, transport and installation services. By working with Mammoet early on in the construction process, the risks and challenges can be managed for a quicker, safer and more efficient operation.

Optimal use of lifting equipment

Many refinery and chemical plant construction sites see multiple contractors and subcontractors working on their own scope of tasks and schedules. Often, this means duplicate resources, both labor and heavy lifting and transport equipment. With separate resources and different schedules, it is difficult to optimize all lifting and transport movements across site. Too many cranes, transport solutions and workers on site leads to underutilization, congestion and budget overruns, not to mention safety concerns.

Mammoet offers an integrated, cross-site approach covering all lifting and transport activities. A single point of contact streamlines communication and allows for the alignment and optimization of site activities and installation schedules – maximizing construction efficiency, safety and cost-effectiveness. One point of contact and one pool of lifting and transport equipment results in optimal deployment of lifting and transport equipment. This minimizes mobilization and demobilization activities and reduces on-site congestion.

Critical path contingencies

Equally important, our centralized approach means contingencies can be made when required, contributing to safer construction while adhering to schedules and budgets.

Construction projects are often subject to change. For example, the delay of a reactor, distillation tower or coke drum can potentially disrupt the overall installation sequence. If surrounding construction work is placed on hold while waiting for the delayed item, the entire construction process, project schedule and budget may be compromised. A carefully planned delivery schedule for key components can minimize the risks of such delays. If an unexpected change occurs, it is essential to get the project back on track as swiftly and safely as possible.

Our engineered heavy lifting and transport experts will have an integrated plan to protect the critical path and will develop engineered solutions to neutralize or mitigate delays and their knock-on effects. Mammoet’s expertise, combined with a broad overview of the entire schedule and the availability of a large pool of skilled people and specialized lifting equipment, enhances flexibility. Our access to these resources means schedule changes can be accommodated while maintaining maximum utilization across the site.

We can improve the quality of the construction process by taking an integrated approach. By optimizing lifting and transport activities across the site with one point of contact, safer and more efficient handovers are possible all along the critical path. With a complete overview, Mammoet can align site-wide lifting and transport plans, allowing for better utilization of equipment and less congestion. The result is even greater flexibility to deal with contingencies, benefitting the overall construction process.

With an overview of all schedules on site, Mammoet can re-align activities if necessary, minimizing impacts on the critical path. In some instances, using one large crane that can reach over structures, rather than a number of smaller pieces of lifting equipment, results in a more efficient critical path. If a vessel is delayed, surrounding project work can remain on schedule and the large crane can lift it into place when it arrives. Such an approach accommodates the delay while helping ensure the entire project schedule stays on track. Realizing such solutions is only possible through dedication, experience and access to a vast array of equipment – allowing for flexibility to safely deal with unexpected situations in the field.

Fast and efficient relocation of plants

Mammoet has the skills, experience and lifting equipment to facilitate the safe and efficient relocation or decommissioning of petrochemical plants.

Often the relocation of a refinery or chemical plant offers a cost-effective alternative to building a new one. With Mammoet as your engineered heavy lifting and transport partner, you can dismantle an entire plant, lift the components onto the means of transport, move everything safely, and then reinstall the plant at its new location. Working with Mammoet guarantees you’ll have the skills, experience and equipment on hand to execute the move safely, on time and on budget.

Reverse modularization

One of the main challenges is that neither refineries nor chemical plants are designed and built with relocation in mind. A detailed engineering study is required to determine how to break down and transport the plant in sections. Where modular construction techniques have been used, relocation is easier. A refinery or chemical plant can usually be dismantled into its original modules and components, such as reactors, distillation towers, or coke drums. However, relocating a stick-built construction requires reverse modularization – designing the most efficient way to break down the processing equipment into reinforced modular sections.

Continue reading

Mammoet can assist you from the very beginning of the refinery or chemical plant relocation process. Our experience is vital in determining the size and weight limits of each component to efficiently lift, transport and re-install them at the new location. Through close cooperation in the early planning and design stage, our engineered heavy lifting and transport specialists can define the engineering parameters and develop an optimal logistical process.

The logistics of plant relocation

Next, it will be up to us to meet that logistical challenge. All modules and components will need to be lifted and transported to the new location safely and undamaged. The locations of both the original and the new site will each present logistical limitations. Our engineered heavy lifting and transport experience are pivotal in realizing the most efficient logistical process.

Route studies help identify logistical bottlenecks, enabling us to avert or mitigate risks and find the safest and most efficient route. The logistical plan also needs to ensure all modules and components arrive in the right order and at the right time at the new location for efficient re-construction of the plant, while optimizing the use of shipping space. The logistical analysis needs to take into account on-site logistical possibilities and the capacity and reach of different lifting equipment for dismantling at the old location and reconstruction at the new site.

Decommissioning petrochemical plants

When a refinery or chemical plant reaches the end of its economic or technical lifecycle, certain vessels and components may still be suitable for re-use. Or they may require dismantling under special conditions in a contained environment. In either case, before the plant is demolished, engineered heavy lifting and transport specialists can remove and transport these items to support the most cost-effective decommissioning within safety and environmental regulations.

Experience is crucial for efficient relocation

Relocation of an existing petrochemical plant as opposed to investing in a completely new one is sometimes dismissed based on the misconception that it is impossible to do this cost effectively. However, with Mammoet’s assistance many refineries and chemical plants can be taken apart, transported and rebuilt in another location, either in the original modules, or reverse modularized in the case of stick-built facilities. Over the years, Mammoet has organized and executed the relocation of a number of plants for the petrochemical and other industries. That hands-on experience is invaluable. Mammoet’s deep expertise enables us to provide specialist insight in many crucial considerations for plant relocation projects.

The key to achieving an efficient and cost-effective relocation process is early cooperation between Mammoet and the client. We need to make a careful step-by-step analysis of the constructional aspects of the refinery or chemical plant and its processing equipment followed by a logistical analysis of the relocation. By accurately determining the maximum allowable sizes and weights for the modular sections and components, we can ensure the required reinforcements are made for safe, damage-free transport. We have seen projects where the lack of good preparation has led to a lot of additional engineering and construction work, resulting in increased costs and delays.

As your heavy lifting and transport partner, Mammoet can oversee the entire disassembly, logistical and re-assembly process. We will have our own people and equipment on-site, and will charter the shipping and arrange all the documentation for the move. The entire process is overseen by our own project manager who is the client’s single point of contact, ensuring on time and cost-effective delivery. We ensure the entire logistical process is handled well and fully integrated with the disassembly and re-assembly on both sites – and that quality assurance is reflected on-site. Instead of working with multiple subcontractors Mammoet will be your one point of contact, making sure the job gets done safely and on time.
