What impact do smart ships, automation and green shipping have on shipbuilding?

The maritime industry is undergoing a profound transformation. Green shipbuilding and sustainable shipping are converging with digitalisation and automation in shipyards and on board ships.

What challenges does the maritime industry face?

At the same time, a persistent shortage of skilled workers, changes in the qualifications required, the rise of alternative propulsion systems and ship recycling are becoming increasingly evident. As if that were not enough, new geopolitical uncertainties and uncertainty surrounding energy price trends are emerging.

All of this goes hand in hand with a shift in traditional engineering, craftsmanship and the experience gained. Legislators are also playing their part by introducing new environmental regulations.

Whilst all of this presents enough challenges in itself, there is also growing pressure on production costs and the timeframes required by shipyards for their projects. This relates not least to issues of collective agreements and location in the shipbuilding industry; in other words, the question arises as to whether Germany can continue to hold its own as a location in an international comparison.

The latest trends and innovations play a major role in meeting, addressing or preparing for all of this. These, in turn, influence other aspects, such as the approach to recruiting young talent in the shipbuilding industry.

The industry must rise to these challenges. The focus here is on smart ships, digitalisation in shipbuilding, operational adjustments and staff skills.

Why is ‘green shipbuilding’ more than just a buzzword?

Awareness of the importance of the environment and its protection is constantly growing. Shipping is, in fact, essentially a green mode of transport, as it is the most efficient method of transport. This means that, from the outset, it produces fewer pollutants than, for example, transport by aeroplane or lorry.

However, fewer pollutants does not mean no pollutants. Indeed, precisely because of its efficiency, shipping is the most widely used mode of transport. It is therefore important to focus on new technologies in this area in order to reduce emissions and improve sustainability.

What climate targets apply to maritime transport?

Against this backdrop, it is no wonder that ‘green shipbuilding’ has long since become a buzzword. In line with this trend, international organisations such as the IMO (International Maritime Organisation) have set ambitious climate targets. For example, all CO₂ emissions from maritime transport are to be reduced by at least 50 % by 2050.

What problems does this entail? Firstly, a general increase in shipping traffic and, secondly, the fact that there are many old ships for which it is no longer cost-effective to retrofit them with new systems. This means that the new ships currently being launched must be much greener in order to meet the targets for the shipping sector as a whole.

Shipyards and shipping companies must now adapt to new production and operational models that incorporate new technologies and bring about a shift in the skills required in shipbuilding. Only through greater digitalisation, automation and more efficient systems can these ambitious targets be achieved.

What does sustainable shipbuilding look like across the entire life cycle?

In this context, it is important to note that sustainable international shipping – which is intended to help achieve these objectives – must take into account the entire life cycle of a ship. This means that everything, from design through to construction and operation, right through to recycling at the end of its life, must be carried out in accordance with environmental considerations.

To achieve this, the following key measures are essential:

• Ship paints must be produced and applied in a way that reduces emissions.
• The materials need to be made more corrosion-resistant in order to extend their service life.
• Design offices, shipyards and research institutes must incorporate new propulsion systems with significantly higher efficiency into their designs.
• The engineers need to improve the hull shape in order to reduce drag and thus lower fuel consumption.
• Shipyards and shipping companies must use hybrid propulsion systems, fuel cells, LNG, methanol and green ammonia.
• Energy consumption and emissions management must be optimised using digital monitoring systems.

What makes Smart Green Ships stand out?

This shift is particularly evident in new-build vessels. Today, Smart Green Ships are designed to meet zero-emission standards. To achieve this, they utilise sensor technology and data analysis. This enables them to monitor their own environmental performance in real time and adjust their systems accordingly.

However, this also means – both nationally and internationally – that technology, digitalisation and sustainability have already become key competitive factors. Shipyards that make the transition to sustainable technologies at an early stage will therefore enjoy a long-term market advantage.

How is digitalisation driving the shipbuilding industry forward?

Digital transformation is the driving force propelling shipbuilding into the next era. At the forefront of this are the automation of shipyards, digitalisation and smart ships. Instead of paper plans, these are now available in digital form. Instead of manual monitoring of processes, this is now carried out using sensors and computers – in other words, digitally and via a network.

Smart ships have become floating data centres. Their systems monitor the engines, navigation and energy consumption in real time. They analyse the data collected in this way and provide key insights. This enables them to optimise the systems and plan maintenance cycles, thereby reducing downtime and, consequently, operating costs.

Digitalisation is bringing robotics, 3D printing and virtual design into the manufacturing process. This enables engineers to model ships – either as a whole or in sections – on a computer. They can simulate them in various scenarios and assess how they withstand the stresses placed upon them. This is followed by automated production.

Our article illustrates just how deeply digitalisation has now permeated the entire yacht and shipbuilding industry Digitalisation in yacht and shipbuilding: smart ships and digital twins.

Which technologies are shaping modern manufacturing?

Typical examples of this trend include:

Digital twins
They create a virtual model of the ship throughout its design, construction and life cycle.

Automated welding robots
They produce the welds more quickly and with greater precision.

Cobots
Collaborative robotics, in which humans and machines work side by side in various stages of production.

AI-based planning tools
They optimise the use of materials and reduce the time taken to build the ships.

These developments are bringing about a number of further changes. For instance, they are improving the efficiency and quality of manufacturing and of the finished products. At the same time, however, skilled workers must also possess digital skills.

What sort of skilled workers are needed for green, digital shipbuilding?

The path towards low-emission, digitally controlled ships requires both traditional craftsmanship and digital expertise. Many skilled workers from Eastern Europe bring precisely this combination to the table – experienced manual skills and growing practical experience in automated, networked production environments.

Frequently asked questions

What does ‘green shipping’ mean in the shipbuilding industry?

Green Shipping refers to a sustainable approach covering the entire life cycle of a ship – from low-emission coatings and more durable materials, through to more efficient propulsion systems and optimised hull shapes, right through to digital emissions management and recycling.

What climate targets apply to maritime transport?

The International Maritime Organisation (IMO) has stipulated that CO₂ emissions from shipping must be reduced by at least 50 % by 2050. As shipping traffic is increasing at the same time, new vessels must be designed to be significantly greener.

What makes a ship a ‘smart ship’?

Smart ships are equipped with sensors and data analytics and function like floating data centres. They monitor engines, navigation and energy consumption in real time, optimise settings and plan maintenance cycles – thereby reducing downtime and operating costs.

What technologies do modern shipyards use?

Key technologies include digital twins, automated welding robots, collaborative robots (cobots) and AI-based planning tools. They boost efficiency and quality, but require skilled workers to have additional digital skills.
