Efficient ship loading under demanding port conditions

In modern port facilities, the efficiency of every process step directly impacts productivity and operating costs. Bulk materials must be handled reliably, flexibly and with minimal emissions. At the same time, different vessel sizes, fluctuating water levels and tight loading schedules place significant demands on loading technology. The wide-span, telescopic ship loader creates the direct link between landside material processing and maritime transport. It ensures the precise and even filling of cargo holds while enabling an efficient and flexible loading process.

Flexible Loading in Changing Conditions

Different vessel dimensions and varying water levels require systems that can adapt quickly and accurately. The telescopic design of the conveyor boom allows the jib to extend variably and adjust in height. This enables the entire cargo hold to be reached precisely without the need to reposition the vessel repeatedly during loading operations. As a result, logistical effort within the port is reduced and vessel turnaround times are significantly shortened, providing a decisive advantage for efficient bulk material handling.

Robust Design for Continuous Operation

Port facilities demand durable and resilient engineering. Wind, weather exposure, dust and continuous operation require systems designed for long-term reliability. The robust lattice boom construction of the ship loader has been specifically developed for these conditions. Its travelling base enables precise positioning along the quay and ensures optimal alignment with the vessel. This keeps the system reliable and operational even under demanding working conditions.

Environmentally Conscious Material Handling

The handling of bulk materials often generates dust emissions that can impact both the environment and working conditions. An adjustable discharge chute at the end of the conveyor boom helps minimise these emissions by ensuring controlled and low-dust material transfer into the cargo holds. This supports a cleaner loading process while maintaining high operational reliability.

Maintenance-Friendly by Design

Efficient port logistics require not only high-performance conveying technology, but also safe and efficient maintenance procedures. Integrated walkways along the main axes provide direct access for inspection and maintenance work. This allows service operations to be carried out efficiently while reducing downtime.

Precision Engineering for Efficient Port Logistics

The telescopic ship loader combines flexibility, robust construction and low-emission material handling within one integrated system. It enables operators to optimise loading processes, reduce vessel turnaround times and maintain a reliable material flow through to departure.

A high-performance solution designed for the demands of modern port logistics.

 

“AI right” instead of “AI first” – what the 2bAHEAD Future Day really revealed

METZEN AI expert Deborah Schwarze attended the 2bAHEAD Future Day in Leipzig to analyse key developments surrounding artificial intelligence, industry models and autonomous agent systems. The event highlighted how profoundly industrial value creation is set to change over the coming years.

Among the key topics discussed were Industry Models, brain computer interfaces and the growing use of specialised AI agents. A dense and highly inspiring day of insights.

What futures research can do – and what it cannot

Before evaluating the content of futures research, it is worth understanding the methodology behind it. In the context of 2bAHEAD, futures research is not about speculation, but about systematic probability assessment. Based on discussions with engineers, software developers and visionaries, development scenarios are formulated and evaluated according to their likelihood.

Much of what is presented on stages like this is technologically plausible. However, the speed and scale at which technologies are adopted in reality follow a different rhythm from developments in research laboratories or investor expectations. Failing to recognise that difference means confusing a roadmap with reality.

The reality gap is structural, not cyclical

Sven Gabor Janszky described a “reality gap”: rising insolvencies in traditional industries alongside massive growth in technology driven companies. At first glance, this may sound like a familiar narrative, but the analysis behind it is more precise than it appears.

The argument is not that the downturn is cyclical and will correct itself over time. The argument is that the gap is structural and continuing to accelerate. The difference is not created by isolated AI tools, but by the agentisation of entire processes. Decision making and execution logic are increasingly being transferred to autonomous AI systems.

Those who still treat this as a pilot project will only recognise the competitive shift once it has already happened.

Industry Models: the underestimated geopolitical factor

One development remained particularly significant beyond the event itself: Industry Models.

These are large, pre trained sector specific models for manufacturing, finance, medical services or e-government, built on deep industry data sets that go far beyond the capabilities of general models. Janszky referred to international developments already underway. Chinese organisations are actively developing and licensing such models for city and infrastructure management, while American platform providers are pursuing comparable approaches under different terminology.

The economic dimension is obvious. Companies that connect to an Industry Model at an early stage can achieve considerable productivity and efficiency gains.

Far less discussed is the geopolitical dimension. Whoever controls the model also controls its governance. That includes decisions about data access, decision logic and participation rights. This is precisely why the topic is not an abstract technology debate, but a strategic business decision.

The Klarna example as the most honest argument of the day

The most tangible statement of the day did not come from a future scenario, but from a real world example. Klarna rapidly automated large parts of its customer service with AI and discovered that efficiency gains and quality losses arrived hand in hand. Customer trust suffered noticeably.

The conclusion was clear: “AI right” beats “AI first”.

The same applies to the agent based approach. Janszky outlined scenarios involving ten to fifteen specialised agents working collaboratively. Technologically, the concept is convincing. In practice, however, it only works with clear governance, defined quality assurance loops and human oversight at the right points.

Speed without control is not an advantage. It is an operational risk.

Backcasting: convincing method, missing foundation

Backcasting was presented as a strategic methodology. The principle is to define a concrete vision for 2035 first and then work backwards to determine the actions required within the next twelve months.

Methodologically, the approach is convincing because it develops strategic logic from a target vision rather than from existing habits.

The practical challenge lies in the foundation. Many companies currently creating future scenarios still lack functioning AI governance, a clear data strategy and defined responsibilities for AI related decisions.

Even the best method requires robust structures. Without them, the future vision remains little more than a well designed presentation.

Robotics: the technology is coming, but more slowly

Robotics forecasts were also part of the Future Day discussions. The prediction of two humanoid robots per household within five to ten years appears technologically plausible when considering developments in motor skills, sensor systems and language models.

The actual adoption curve is likely to be slower. Not because the technology will fail to emerge, but because infrastructure, regulation, social acceptance and cost development all follow their own timelines.

The technological direction is clear. The timeframe remains far more complex.

What remains

The gap between companies structurally integrating AI and those still operating in isolated pilot projects is becoming a measurable competitive factor.

The answer is not the perfect strategy.

The answer is the first concrete step.

What this means for METZEN

Manufacturing is one of the core sectors for which Industry Models are being specifically developed. As a company with deep expertise in mechanical and plant engineering, METZEN operates directly within this environment.

That is why we actively engage with these developments. With a clear digital strategy and the ambition not to view Industry Models as an external trend, but as a strategic lever for our industries and customers.

The reality gap described at the event directly affects traditional industrial companies. Through the work of our AI expert, METZEN has already begun establishing the first structural foundations. Not as an isolated pilot project, but as a long term development with direct practical relevance.

That is exactly what makes the difference.

AI between progress and loss of control – what truly matters now

Dear customers,
dear colleagues,

The current debate around artificial intelligence is shaped by two very different perspectives.

On the one hand, there is remarkable progress: rising productivity, new business models, and an unprecedented acceleration of decision-making and innovation processes. Voices such as Sam Altman describe AI as the key technology of our time, a clear lever for growth, efficiency, and business transformation.

On the other hand, there are distinctly more critical voices. The discourse on superintelligence, led among others by Eliezer Yudkowsky and Nate Soares, paints a far more radical picture: systems that are no longer fully understood, that do not develop linearly, and whose behaviour increasingly escapes control. The underlying thesis is as simple as it is unsettling: as capability increases, not only does value grow, but so does unpredictability. Systems are no longer fully engineered but are, in part, “trained”, with outcomes that are no longer entirely transparent even to their creators.

Between these two poles, progress and loss of control, lies the real challenge for industry and the mid-sized sector.

Because in day-to-day operations, the question is not what technology can do.
The decisive question is: does it work, reliably, consistently, and under real conditions?

For the customer, in the end, no concept counts.
No trend.
No vision.

Results count.

Whether a plant runs continuously.
Whether processes remain stable.
Whether interfaces function seamlessly.
Whether delivery deadlines are met.
Whether risks are identified early and managed effectively.

And this is precisely where true complexity begins.

The systems we operate in today are fundamentally different from those of just a few years ago. They are interconnected, data-driven, dynamic, and in part no longer fully transparent. Decisions no longer arise in isolation, but through the interaction of software, mechanics, data, and operational processes.

This means: errors no longer occur linearly.
They occur systemically.

Small deviations can have major consequences.
Unidentified interactions can destabilise processes.
And these effects rarely appear in the concept, but in operation.

When it matters.

These are the moments that determine success or failure.

Moments when plants come to an unexpected standstill.
Moments when processes begin to fail.
Moments when time pressure meets complexity.
Moments when rapid decisions must be made under uncertainty.

In these situations, no isolated technology will help.
Nor will any standard solution.

What the customer needs above all in these moments is one thing: confidence in execution.

The ability to understand interdependencies.
The ability to identify risks at an early stage.
The ability to design systems that remain stable even under changing conditions.

This is where the role of engineering is fundamentally shifting.

It is no longer solely about design.
It is about integration.

No longer about individual solutions.
But about interaction within the overall system.

No longer solely about technical excellence.
But about responsibility for the outcome.

And it is at this point that the decisive difference emerges.

The role of the integrator becomes a key success factor.

An integrator does not think in components, but in interdependencies.
They do not reduce complexity, but make it manageable.
They take responsibility, not only for the solution, but for its performance in operation.

This is precisely where METZEN positions itself.

With senior engineers who do not only develop, but contextualise.
Who do not only build, but understand.
Who do not only deliver, but take responsibility.

For our customers, this means in concrete terms:

fewer interfaces and therefore reduced susceptibility to errors, greater transparency and clarity in complex projects, higher operational reliability even under dynamic conditions, faster and more well-founded decisions in critical situations, and above all reliability in the moments when it truly matters.

Because in the end, success is not decided on paper.

It is decided in operation.
In everyday practice.
Under real conditions.

When it matters.

The future of industry will not be determined solely by the performance of technology.
But by the ability to master it.

For the customer.
For the process.
For the result.

And that is exactly what METZEN stands for.

Yours sincerely,
Lars Netzel

When 767 kilometres make history. Guinness World Record for the Viking Link. Powered by precision and welding expertise from METZEN.

The Viking Link is listed in the Guinness World Records. At 767 kilometres, it is officially the longest land and subsea high-voltage direct current interconnector in the world. This distinction marks a milestone in European energy engineering. The connection between Great Britain and Denmark enables the distribution of renewable energy to more than 1.4 million households and stands for technical precision at the highest level.

METZEN Industrie Service at its Gochsheim site contributed to this world record. For the converter stations, METZEN manufactured transformer covers and high-precision aluminium welded components. In close cooperation with Siemens Energy, components were produced that withstand extreme conditions and ensure long-term operational reliability.

The added value of the Viking Link is measurable. Power flows can be controlled flexibly between both countries, bottlenecks are balanced, and renewable energy is integrated efficiently. The benefits are particularly clear in the management of Danish wind surpluses. In the past, these often led to negative prices or grid congestion. Today, they can be exported to Great Britain with precision and economic efficiency. This stabilises the grids and increases market efficiency.

The interconnector strengthens security of supply, supports the reduction of CO₂ emissions and contributes to more stable electricity prices. The Guinness World Record recognises not only the length of the project, but also the technical excellence that made it possible.

The Viking Link is a European flagship project. With its manufacturing and welding expertise, METZEN demonstrates how industrial precision plays a decisive role in turning technical vision into a world record.

Strong material flow as a key success factor in plant engineering

The extraction and processing of aggregates, minerals and raw materials are characterised by high throughputs, varying material properties, and increasing demands on environmental protection and operational safety. Efficient material handling is not an isolated process step, but a decisive lever for economic efficiency, plant availability and product quality.

METZEN develops precise and reliable material handling solutions for real operating conditions. The focus is on stable material flows in conveying, dosing, storage and loading of bulk materials, precisely aligned with material characteristics, site conditions and process objectives.

GERWIN Silotechnik, a product brand of METZEN, complements this portfolio as a specialised provider in steel and plant engineering. GERWIN delivers robustly engineered solutions ranging from individual components to complete plant systems, drawing on decades of experience in demanding material handling applications.

Material Handling in Plant Engineering – When Technology Supports Processes

In plant engineering, success is not defined by the performance of individual machines, but by the interaction of all components along the material flow. Fluctuating throughputs, dust emissions, material losses and restricted space quickly expose the limits of standardised solutions.

METZEN addresses these challenges with holistic plant concepts. Mechanical and electrical engineering are consistently integrated with process and plant planning. The result is solutions precisely tailored to operating conditions, from the primary crusher through to loading. Sound structural design, transparent planning and precise fabrication ensure stable, low-maintenance and efficient material flows.

This approach is reflected, for example, in the integration of modern classification technology into existing plants. At one site, previously unclassified sand was made marketable for the first time through a compact, low-emission solution. Despite limited space, new sales markets were opened and the site’s profitability was sustainably improved.

Material Handling for Aggregates and Bulk Materials

The raw materials industry places specific demands on material handling: abrasive materials, high mass flows and continuous operation. METZEN delivers robust conveying systems, silos, dosing and discharge units, as well as high-performance loading solutions for gravel and sand plants, processing facilities, and asphalt and ready-mix concrete plants.

Energy-efficient drives, durable designs and well-engineered dust control concepts ensure economical operation with high environmental compatibility. Modular designs allow precise integration into existing structures without compromising performance or safety.

Planning, engineering, fabrication, transport, installation and commissioning are closely coordinated. Combined with comprehensive engineering and service expertise, this results in plant solutions that remain technically precise, economically viable and reliable throughout their entire lifecycle.

Another example of this system expertise is the implementation of complex dosing and conveying systems in hydrate plants. Here, GERWIN delivered a modular solution with multiple silos, precise weighing and an energy-optimised material flow. High dosing accuracy, process reliability and measurable CO₂ savings underline the impact of well-designed material handling on overall efficiency.

Material Handling with Responsibility

METZEN understands material handling as an integral part of sustainable plant concepts. Robust construction, energy-efficient technology and service-friendly design ensure long-term availability and high performance, even under demanding operating conditions.

With strong engineering capabilities, in-house fabrication and installation teams operating across Europe, METZEN supports its customers strategically and operationally from the initial concept through to long after commissioning.

Talk to us. Together, we develop material handling solutions that make your raw material processes more efficient, safer and future-proof.

Showing responsibility. Supporting humanity.

Global crises, natural disasters and humanitarian emergencies always affect the most vulnerable first. When medical care is lacking, time is critical and every decision can save lives, organisations are needed that act independently, professionally and with deep human commitment. This is precisely where the work of Médecins Sans Frontières (Doctors Without Borders) begins.

METZEN is a Partner Company of Médecins Sans Frontières in 2026. Through a donation, we support the organisation’s global medical emergency aid and make a tangible contribution to the care of people in acute crisis situations.

Trust built on clear values

For METZEN, the partnership with Médecins Sans Frontières reflects a clear sense of purpose. As an internationally active company, we bear responsibility towards our customers, partners, employees and society. This responsibility is firmly anchored in our Code of Conduct.

Fairness, transparency and responsible behaviour form the foundation of our actions. This includes clear standards in how we work together, integrity in business processes and transparency across supply chains. These values are not merely internal guidelines; they are the benchmark for every partnership METZEN enters into.

Thoroughly reviewed – consciously committed

Prior to the partnership, METZEN was reviewed in accordance with the donation and compliance guidelines of Médecins Sans Frontières. This careful review underlines the organisation’s high standards for its partners and confirms that METZEN meets these requirements.

Our support is independent of political interests or commercial objectives. It is driven by compassion, respect and a shared commitment to help where help is urgently needed.

Medical emergency aid worldwide

Médecins Sans Frontières provides medical emergency aid in crisis and conflict zones and in the aftermath of natural disasters – quickly, efficiently and without bureaucracy. The organisation operates in more than 70 countries, treating the sick and wounded, caring for malnourished children, providing clean drinking water and establishing basic sanitation infrastructure. Médecins Sans Frontières helps people regardless of their origin, religion or political beliefs.

A partnership based on conviction

As a Partner Company in 2026, we stand behind this humanitarian mission. For METZEN, working with Médecins Sans Frontières is a clear statement that economic success and social responsibility are inseparable.

We are convinced that sustainable action is reflected not only in products, services and processes, but also in how companies demonstrate integrity and take responsibility in challenging times.

When It Matters. Our Credo.

True partnership becomes apparent under pressure. When plants fail, risks increase, and time is short, experience, clarity, and reliable action are what count. “When it matters” is METZEN’s credo and reflects the mindset that guides everything we do.

More than 30,000 completed projects demonstrate this reliability and measurable results. Our customers operate in industries where process safety is critical, such as the circular economy, the energy and raw materials sector, and food production. These conditions demand the highest standards in technology, availability, and responsibility.

To meet these demands, our Senior Engineers, experienced specialists with in-depth industry knowledge, analyse complex technical systems, assess risks, and identify optimisation opportunities. Working closely with our customers’ teams, they provide the foundation for informed decisions, even under time pressure or in exceptional situations.

The importance of this approach is most evident when unexpected events occur. After the collapse of two silo structures, METZEN was on site within a very short time, developing a safe dismantling strategy and implementing it under challenging conditions. Speed alone was not decisive; it was the ability to assess risks correctly and act in a structured way.

We view technical complexity as the starting point for sustainable solutions. We approach engineering with foresight, guiding the process from precise site surveys to ready-to-implement installations. Modern tools and proactive project planning provide early certainty and minimise later interventions during operation.

This systematic approach also proves its value in critical situations. After a major fire in a fertiliser plant, METZEN quickly developed an emergency plan that combined repairs, temporary solutions, and the use of existing supply chains. Production could be resumed faster than expected, avoiding prolonged downtime.

At METZEN, solutions are individual, not standardised. Our plants and machinery are designed based on a deep understanding of each customer’s production logic. Functionality, efficiency, and sustainable long-term performance are always at the centre of our work.

When standard solutions are insufficient and causes are unclear, our Senior Engineers go on site immediately, assess the situation themselves, and take targeted action. One example is an assignment on a gravel dredger in the middle of a lake, where damage could only be identified through direct inspection. This illustrates our principle: problems are not evaluated from a distance—they are solved.

This approach is reflected in our processes. Supported by an experienced assembly team, systematic quality management, and a reliable network of long-standing suppliers, we deliver solutions on time, safely, and efficiently, even under difficult conditions.

Our work does not end with commissioning. We continue to support plants, optimise processes, and safeguard performance over the long term. Whether during operation, strategic projects, or exceptional situations, METZEN ensures that solutions work.

When it matters.
