After all, in the highly competitive environment of refineries and chemical plants, time is the currency that matters most.

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.

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.

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.

Our familiarity with petrochemical plants and their safety procedures is particularly valuable, since expansions and alterations that occur over time tend to make refineries and chemical plants more complex and congested. Certain equipment and components become hard to access with heavy lifting and transport equipment. Mammoet has extensive experience working on refineries and chemical plants, with established knowledge of the specific requirements for each type of site. Consequently, we offer a highly efficient and professional heavy lifting and transport service in petrochemical plant maintenance.

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 is pivotal in realizing the most efficient logistical process.

Route studies help identify logistical bottlenecks, enabling us to avert or mitigate risks and to 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.
