The Encounter Sparked by a Need – Where It All Begins
The story of a tank project begins with identifying the customer’s need. Sometimes it stems from a major investment; other times, the need arises from change – storage capacity must be increased, or an old tank no longer serves its purpose. Forssa Engineering’s experts start mapping out what kind of solution would best support the customer’s process. Is it a storage tank, a process tank, or perhaps a district heating accumulator? The customer is responsible for process design, but Forssa Engineering ensures that the delivered tank fits its intended purpose.
Often, discussions help the customer understand when an on site-built, welded steel tank is the most cost-effective option for their project – tank size, installation conditions, and schedule are key factors.
Teams work together from the very beginning: sales ensures the feasibility of the initial data, design supports the technical side of the solution, and the installation team already considers practical implementation on-site. Each phase is interconnected, and the customer is involved throughout the journey.
Building Boundaries and Frameworks – At the Heart of Contract Negotiations
Once the customer’s need is clarified and Forssa Engineering’s offer has been sent, one of the most critical phases of the project begins: contract negotiations. At this point, technical and commercial boundaries are no longer just numbers or lists – they become a shared understanding of what is to be delivered.
At the negotiation table, industry-specific requirements are reviewed – chemical storage, temperature resistance, and corrosion protection – ensuring that every detail is considered. Tank volume, material choices (different steel grades such as carbon steel or stainless steel), site conditions, and schedule form the project framework, around which the entire implementation is built.
Before formal negotiations, Forssa Engineering’s offer serves as a clear foundation for execution and a starting point for discussion. It reflects the customer’s inquiry and requirements and defines the framework within which the project can be carried out. During negotiations, the offer and the customer’s wishes and requirements are combined into a structured plan – resulting in a contract that is not just a piece of paper but a shared plan and a promise to complete the project as agreed.
Sales department acts as the link between the customer and Forssa Engineering’s experts during negotiations. Sales ensure that all commercial terms, responsibilities, and project objectives are clearly agreed upon. Sales is supported by design and installation teams, who bring technical and practical perspectives to the table – ensuring that agreed solutions are feasible and meet both customer needs and real-world conditions.
Negotiations cover all essential details of the project to create a shared understanding and clear rules for implementation. Sales’ role is to keep the big picture under control and ensure that the contract provides a solid foundation for a successful project.
From Idea to Engineering – The Story of Design
Once the contract is signed, Forssa Engineering’s design team gets to work, and the technical implementation of the project begins. The first step is strength calculations – ensuring that the future tank can withstand all requirements and conditions. When the calculations are correct, materials are ordered based on the design: the right steel grade, tank components, and (if needed) insulation that meet both customer needs and standard requirements.
The customer’s input data guides the design. Based on this, a 3D model and main dimension drawing of the tank are created, forming the technical foundation of the project. Every line and measurement is deliberate – they are not just technical details but promises that the tank will meet all required standards and legal constraints. EN 14015, relevant Eurocode standards, and strength calculations are everyday work for the design team.
For every tank, the team always performs FEA calculations to ensure structural integrity and correct sizing. CFD analyses are used when the process involves special flow or temperature requirements. This way, every detail is verified – not just on paper but also computationally and practically. Third-party inspections confirm compliance and serve as proof that quality and standards are ensured at all levels.
As design progresses, the team stays in close contact with the site. Design is not isolated from the implementation – every solution affects installation and practical execution. Connection techniques, lifting points, and assembly sequence are always planned to be cost-effective and feasible. As design advances, welding and detail drawings are produced to guide site operations and ensure that implementation follows the plans.
The essence of design can be summed up in one thought:
“The most important thing is to ensure structural integrity, leak-tightness, and that the tank works in practice – not just on paper.”
Thus, the design phase combines technical expertise, customer needs, and practical realities – and this is where the tank’s final form takes shape.
On-Site Activities and Realities – The Practical Side of Tank Installation
When the plans are ready, the site begins to live on its own rhythm even before materials and installers arrive. First, a thorough inspection and survey are carried out: the site area is reviewed, lifting equipment and crane requirements are assessed, and pre-assembly areas are carefully planned. These steps anticipate future challenges and ensure everything is ready when materials arrive.
When material deliveries begin, the site fills with movement and collaboration. Experienced installers and the site manager ensure that every work phase proceeds according to drawings and overall design. Measurements are taken regularly – circumference checks; weld quality is visually inspected by a trained welder, and the site manager performs his own weld inspections. External NDT inspections provide an additional layer of quality assurance.
Quality assurance and documentation go hand in hand on-site. Quality and final documentation start during the design phase and continue throughout the project: every step is carefully documented to ensure quality and safety. Documentation is actively monitored and reported internally and to the customer, and third-party inspections confirm that the final result meets all requirements.
On-site, the importance of the team stands out. Every member knows their responsibility, and collaboration is open both within the team and toward the customer. Challenges arise – sometimes weather conditions change rapidly, other times material logistics require creativity. The key is the ability to react and solve problems together because site success is not the sum of individual performances but the achievement of the entire team. Site management requires clear communication and accountability.
All problems and successes are discussed openly, and the door is always open for the customer – they can visit the site anytime and see how the project is progressing in practice. This builds trust that carries through the entire project.
The installation manager sums up the spirit of the site aptly:
“The men (at site) are everything – without an excellent team, we are nothing.”
As installation progresses, tangible results emerge: shell courses rise, weld seams join the parts together, and the tank begins to take its final shape. When the on-site work ends, what remains is the delivered tank and an installation team proud of their shared achievement – and a client whose needs have been met.
