GN has recently supplied a containerized oily sludge treatment system to a customer in Africa, offering a compact, modular, and transport-friendly solution for efficient industrial and oilfield waste management. These systems are increasingly adopted in international projects due to their flexibility, ease of installation, and adaptability to harsh field conditions.

The system is composed of four main modules working together as an integrated process unit. The first is the pre-mixing tank module, which is responsible for homogenizing the oily sludge before treatment, ensuring a more stable and consistent feed to downstream equipment.
The second component is the vibrating screen module, which removes larger solid particles at an early stage of the process. This helps protect downstream equipment and improves overall system efficiency.

The third and core unit is the three-phase decanter centrifuge module, designed to simultaneously separate solids, water, and oil. This key equipment enables efficient hydrocarbon recovery while significantly reducing final waste volume.
Finally, the system includes a chemical dosing module, which allows controlled injection of chemicals to enhance separation performance, especially when dealing with complex emulsions.
With this integrated containerized solution, the customer benefits from faster deployment, reduced on-site footprint, and improved operational efficiency. This project in Africa further demonstrates the value of advanced separation technology in demanding waste treatment applications.

In the demanding landscapes of the Middle East and North Africa, drilling operations often resemble a high-stakes balancing act, where efficiency, environmental compliance, and reliability must align perfectly. For a regional client, GN Solids Control delivered a comprehensive solids control and waste management solution, combining advanced equipment with practical engineering to meet these challenges head-on.

Rather than supplying standalone machines, GN approached the project as a complete process solution. The goal was simple yet ambitious: create a seamless flow from drilling fluid treatment to waste handling, minimizing losses while maximizing performance.

At the center of this system is the Decanter Centrifuge, a precision-driven unit designed to tackle fine solids that escape primary separation stages. By spinning at high speeds, the centrifuge removes ultra-fine particles, helping maintain optimal drilling fluid properties and reducing the need for excessive dilution or chemical treatment. The result is a cleaner, more stable fluid system that supports consistent drilling performance.

Working alongside the centrifuge is the Vertical Cuttings Dryer, a crucial component for drilling waste management. As cuttings are generated, the dryer reduces their liquid content, allowing valuable drilling fluids to be recovered and reused. This not only lowers fluid consumption but also helps operators meet strict environmental standards, a growing priority across the MENA region.

To keep materials moving efficiently across the site, GN integrated Vacuum Pump Systems into the solution. These units act like industrial “lungs,” quickly transferring sludge, drilling waste, and residual fluids from one point to another. Whether used for pit cleaning or solids transfer, vacuum pumps reduce manual labor and improve overall site efficiency, especially in complex or confined environments.

The synergy between these systems creates a closed-loop workflow, where drilling fluids are continuously treated, recovered, and reused. This approach reduces waste, cuts operational costs, and enhances environmental performance, all while maintaining a high level of operational reliability.

Designed specifically for the harsh conditions of the MENA region, the equipment features robust construction, high-temperature tolerance, and user-friendly maintenance design. Each component is built to withstand intensive use while delivering consistent performance over time.

This project highlights GN Solids’ capability not just as an equipment manufacturer, but as a solution provider that understands real-world oilfield challenges.

For an international oilfield service company, GN Solids Control has delivered a Drilling Fluids Mixing and Storage Tank system designed to bring precision, stability, and adaptability to complex drilling environments.

This project focuses not only on equipment supply, but on optimizing the entire workflow of drilling fluid handling. From initial mixing to continuous storage and circulation, the system acts as a central hub that keeps drilling operations supplied with properly conditioned fluids at all times.

One of the key strengths of the system is its integrated mixing design. By combining agitators, mud guns, and fluid transfer pipelines into a coordinated structure, the tanks ensure that drilling additives are evenly dispersed and fluids remain homogeneous. This reduces the risk of solids settling and helps maintain consistent rheological properties, which are essential for effective cuttings transport and wellbore stability.

Equally important is the system’s operational flexibility. The tank configuration can be adapted based on project requirements, allowing operators to allocate capacity for different stages of drilling. Whether handling high-volume fluid preparation or maintaining reserve storage, the system provides the versatility needed for dynamic field conditions.

Another highlight is its modular engineering approach. Designed for international deployment, the tanks can be easily transported and assembled on-site. This modularity not only reduces installation time but also simplifies future expansion or relocation, making it a practical choice for projects that demand mobility and scalability.

From a reliability standpoint, GN Solids emphasizes durability and safety throughout the design. The tanks are constructed with robust materials and protective coatings to withstand harsh oilfield conditions, including corrosion and extreme weather. User-friendly features such as access platforms, handrails, and well-arranged piping systems further enhance operational safety and maintenance efficiency.

This project reflects GN Solids’ broader philosophy: delivering not just equipment, but complete, field-proven solutions that align with real operational needs.

As drilling operations become more complex and safety requirements continue to tighten, effective gas control in drilling fluids has become a critical factor for successful project execution. In response to these challenges, GN Solids Control has supplied **nine sets of drilling mud vacuum degassers** to a European client, delivering a reliable solution to enhance both operational stability and safety performance.

Rather than being viewed as a standalone piece of equipment, the vacuum degasser plays a vital role within the entire solids control system. Gas intrusion into drilling fluid can occur at various stages of drilling, especially when encountering gas-bearing formations. If not properly removed, gas-cut mud can lead to reduced fluid density, unstable circulation, and increased risk of well control incidents. By integrating efficient degassing technology, operators can maintain consistent drilling parameters and avoid costly disruptions.

GN’s vacuum degassers are designed to function as a **stabilizing unit within the drilling fluid circulation system**. Installed downstream of primary solids control equipment, the degasser continuously processes returning drilling fluid, removing both free and entrained gases before the fluid proceeds to subsequent treatment stages. This ensures that downstream equipment such as desanders, desilters, and centrifuges can operate under optimal conditions without gas interference.

The system operates by creating a controlled vacuum environment, allowing gas to separate rapidly from the liquid phase. This process not only restores the density of the drilling fluid but also improves its overall rheological properties. As a result, drilling performance becomes more predictable, and the risk of pressure fluctuations within the wellbore is significantly reduced.

From a project management perspective, supplying **nine identical units** provides the client with a standardized equipment fleet. This standardization simplifies installation, operation, and maintenance across multiple rigs or drilling sites. Operators benefit from consistent performance, while spare parts management and technical training become more efficient and cost-effective.

Another important aspect of this project is GN’s focus on **long-term reliability and ease of maintenance**. The vacuum degassers are built with durable components and optimized internal structures to handle continuous operation in demanding drilling environments. The simplified mechanical design allows for quick inspection and servicing, helping reduce downtime and maintain steady production schedules.

In addition, GN’s equipment can be configured to meet European safety and compliance requirements, ensuring that the degassers are suitable for use in both standard and hazardous environments. This flexibility allows the client to deploy the equipment confidently across a range of drilling applications.

Through this delivery, GN Solids Control once again demonstrates its commitment to providing system-oriented solutions rather than individual equipment.

As large-scale urban infrastructure projects continue to expand in South Korea, shield tunneling technology plays an increasingly important role in constructing underground transportation networks, utility pipelines, and municipal infrastructure. To support these demanding projects, GN Solids Control has supplied six packages of TBM slurry separation plants designed for slurry balance tunnel boring machines.

In slurry balance TBM operations, the excavation process generates large volumes of slurry containing soil, sand, gravel, and fine particles. If not properly treated, these solids can affect slurry performance, increase equipment wear, and disrupt the tunneling process. A reliable slurry separation system is therefore essential to maintain efficient TBM operation and ensure stable excavation conditions.

GN’s slurry separation plants are engineered to handle high-capacity slurry treatment requirements, with processing capacities of 500 m³/h and 750 m³/h. These systems are designed to continuously separate excavated solids from drilling slurry and recycle the cleaned fluid back into the tunneling circulation system. This recycling process reduces the consumption of fresh water and bentonite while lowering overall waste disposal costs.

Each of the six systems is equipped with three essential treatment modules: a scalping screen, a desander, and a desilter. These components work together to achieve multi-stage separation. The scalping screen removes oversized particles and debris at the initial stage, protecting downstream equipment and ensuring smoother processing. The desander module then uses hydrocyclone technology to separate medium-sized sand particles from the slurry. Finally, the desilter stage further removes fine particles, improving the overall slurry quality and enabling effective reuse.

One of the notable features of GN’s slurry separation technology is its modular system architecture. Each module is built as a self-contained unit, allowing easy transportation, quick installation, and convenient maintenance. This modular design also provides flexibility for project engineers to arrange the system layout according to site conditions, which is especially valuable for tunneling sites where available working space may be limited.

The compact footprint of the system is another key advantage. Despite its high processing capacity, the equipment is designed to occupy minimal space, allowing efficient use of construction areas. Fast assembly and disassembly further reduce project preparation time and help contractors maintain tight construction schedules.

In addition to operational efficiency, durability is a core consideration in GN’s equipment design. Shield tunneling slurry often contains highly abrasive particles that can cause significant wear to separation equipment. GN uses high-quality materials and robust structural designs to ensure long-term reliability and stable performance under continuous operation.

The successful delivery of six TBM slurry separation plants to South Korea demonstrates GN Solids Control’s growing presence in the global tunneling and trenchless construction market. With advanced separation technology, flexible modular systems, and proven reliability, GN continues to support infrastructure projects worldwide.
