Conference Agenda

The paper shows the industry's experience in implementing extreme projects. The list includes projects completed between 1991 and 2023

The sustainability of the HDD industry depends on contractors' technical capabilities and performance, but also on their ability to properly manage projects from a contractual perspective. This presentation does not pretend to be a legal course. Instead, it is a practical approach to the legal aspects affecting the day-to-day operations of HDD contractors and an attempt to highlight some of the most critical contractual topics.

The paper will be devoted to the presentation of basic technical and technological problems of HDD technology in the transition from an onshore to an offshore environment. The author will also present considerations for drilling muds in a challenging environment, thermally conductive fills, potential annular space seals, as well as drilling technology issues.

Microtunneling is a commonly used trenchless technique by GAZ-SYSTEM S.A., the primary technique for performing short crossings of single obstacles. This technology provides a high degree of confidence in the successful completion of the crossing. However, the method of performing microtunnels and the additional technologies that are associated with their use are not found in traditional implementations carried out by other network operators, e.g. for water or sewer. These additional technologies, as well as experience in the implementation of microtunnels with steel pipes, will be in this presentation.

Careful planning of the drilling route is crucial for any HDD drilling. However, calculating the optimal drilling route, taking into account all the factors that can affect its course, is a complex and often time-consuming task. In the case of complex drilling, even dedicated planning tools prove insufficient. Then there is nothing left but to make calculations manually.

That's why we have developed Quickplanner3D in close cooperation with experienced HDD specialists. With this clever software, you can automatically and quickly plan the optimal drilling route. The intelligent algorithm calculates the shortest route in three dimensions and reliably takes into account all points and limiting parameters. This makes it possible to efficiently plan and quickly check the feasibility of the drilling route. The software does not need to be installed. It can be used with any computer or laptop with Internet access.

Analyses are presented comparing the cost of constructing gas networks for four projects using trench and trenchless methods. These analyses show that for the majority, the trenchless method is the economically more attractive choice. The total costs of constructing gas networks using the trenchless method in 3/4 of the analyzed cases are lower and account for 83% ÷ 90% of the costs of the trench method. In one case, the costs of execution by the open trench method are lower and account for 98% of the costs of execution by the drilling method.
When analyzing the installation work, in the trenchless method a large share of the cost is made up of drilling and jacking, which can often exceed the cost of excavation - especially for large network diameters.
In order to economically evaluate a given gas network construction project and select an appropriate construction method, many factors must be taken into account. These include the type of soil found in the area, the depth of groundwater, the multiplicity of underground infrastructure, the pavement found along the network route, and the diameter of the pipeline associated with the price of drilling. Each project should be approached individually.

The Primus Line system for the rehabilitation of pressure pipelines in the range of DN 150 - DN 500 with various working media (water, wastewater, industrial water, oil, and gas) will be presented during the presentation. The Primus Line system can rehabilitate pipelines through elbows, even over long distances (up to 1,000 meters or more). Typical Primus Line projects will be presented using examples from practice, mainly in the context of rehabilitation:

- transmission pipelines
- siphons (under rivers and linear facilities)
- Pressure pipelines (including sewers)
- Pipes on bridge structures with expansion joints
- Pipelines in seismically active and undermined areas
- Overhead lines
- Pipelines located in manholes, tunnels, and collectors
- Pipelines in industrial areas

Concentrated knowledge, decades of worldwide experience and the vision of Diringer&Schiedel , Pipe Aqua Tec GmbH, RS Technik AG, Applied Felts Ltd have naturally evolved into global trendsetting for the CIPP industry, resulting in elite technologies. Is the water and sewer industry in Poland ready to consciously adopt the best, fully mature and tested solutions with the welfare of its residents in mind ?

The author of the presentation, representing the company Sezam Instal, which has been a representative of the largest and most important global players in the CIPP technology sector on the Polish market for several decades, will present his considerations and resulting proposals for further development in the area of renovation of pressurised water pipes.

The issues of safety and health of people using water pipelines renovated with CIPP technology, reliability and repeatability of installations, the highest standards in the production process and monitoring of liners and resins are just some of the important jigsaw puzzles from which the picture of the Polish reality of CIPP renovation in the drinking water pipeline sector is being pieced together.

The author will try to show why all of the above aspects are critical and why the lack of even one of them, inevitably, as a function of quite a short time , leads to very costly consequences.

AOC is a global supplier of specialty resins that enable customers to create tough, durable, and versatile products and components for applications in coatings and protective barriers, colorants and visual effects, adhesives and specialty products, and composite resins. With strong worldwide manufacturing and scientific capabilities, the company works closely with customers to provide unparalleled quality, service, and reliability for today and create innovative solutions for tomorrow.

AOC Resins is a leading supplier of styrene-free resins for trenchless CIPP applications. Manufactured by GMP (Good Manufacturing Practice) and under a comprehensive Total Quality Control Management system, AOC boasts an excellent track record in selling high-quality resins for potable water applications.

Beyone series styrene-free resins are used in systems approved for drinking water by the PZH and KIWA. Certification of these resins is accomplished through extensive, multi-day KIWA audits, involving evaluation of the entire chain from raw materials to final product and testing. As a result, the CIPP customer receives standard-approved, high-quality resins with excellent consistency, allowing relining companies to have excellent repeat installations.

The agenda will include information to:

• Installation processes/material overview
• Results of site investigations
• Hints for the installation of different methods
• Results of the IKT product test „Manhole Rehabilitation“
• Sources of error during rehabilitation
• Conclusion
