Harbors are modern and increasingly complex facilities. Their processes are unimaginable without electricity – from traffic guidance systems to transporting cargo. Restrictive regulations and European laws regarding environmental issues of power supply are a huge challenge modern harbors are facing. Topics focusing on energy efficiency, power quality, and grid stability are equally important. Harbors are looking for an environmental friendly solution that proves to be cost-effective and reliable.

TIP for harbors
Totally Integrated Power offers the entire spectrum of reliable, safe and efficient power supply for future-oriented harbors. The extensive selection of software solutions for power supply and automation offers key advantages for integrated digital monitoring and operations management processes. The hardware portfolio ranges from low-voltage circuit breakers to entire microgrids and land connection systems.
Modern harbors are confronted with major challenges: They need to adapt to stricter requirements on environmental performance, increasing power supply costs, rising demands on protection and automation solutions for the power system, infrastructural complexity, and the integration of operational data into the enterprise IT environment. Totally Integrated Power from Siemens supports harbors with a reliable and efficient power supply for the entire harbor infrastructure. An integrated approach – from planning and installation to services – helps harbors exploit their full energy-efficiency potential.
The power supply is uniquely integrated into the complete lifecycle of harbor facilities. Once industrial automation and building automation are combined, along with other elements in the Siemens portfolio, state-of-the-art harbors can face all challenges with confidence.
If necessary, the required medium-voltage can be directed quickly and easily to the relevant parts of a harbor using prefabricated e-houses. Seamless interfaces and the extensive expertise accumulated by Siemens in all aspects of power supply, from analysis to planning and system integration, operation and service, offer a smooth, reliable path forward and provide significant added value. The land connection system enables ships in the harbor to obtain the electric power they need via a connection to the medium-voltage grid on land and switch off their generators.
TIP is an integrated power supply solution that is being successfully used in harbors around the world. Learn more in the following reference projects.
Nacala Corridor Project / CLN | Nacala-a-Velha, Mozambique
To provide a reliable power distribution solution for the new Nacala-a-Velha seaport in Mozambique was quite a challenge. Despite its tight schedule and the difficult transport infrastructure in the African country, this project was delivered well within time and budget. The seaport received a complete containerized solution with transformers, medium- and low-voltage switchgear, and appropriate motor control centers for supplying power and controlling the conveyor belt motor drives in five prefabricated E-Houses.
Siemens met the high power availability requirements precisely while considering the on-site environmental conditions. The E-House’s internal overpressure prevents ingress of coal dust and coatings such as from salty sea air. The on-time delivery of this highly efficient power solution meant a timely startup of harbor operations.
Hamburg Port Authority | Hamburg, Germany
Cruise ships in the port of Hamburg consume about 1.2 metric tons of fuel per hour for the ten hours they lie at anchor. The environmental pollution caused by their diesel units is correspondingly high, which is why the harbor authority was looking for a better solution, partly with the proximity of residential buildings in mind. It worked with Siemens to develop the Altona land connection system to enable the nearby cruise ships to be supplied with power and switch their diesel engines off. The electricity that is needed passes via a 50-Hz medium-voltage switchgear unit to transformers that convert it for SIPLINK.
SIHARBOR, the element at the heart of Siemens’ land connection system, then converts the electricity to the required frequency of 60 Hz and a rating of 12 MVA, and transmits it to the ships. As the main contractor, Siemens constructed the plant during winter, to minimize the impact on cruise ship traffic. The project was completed on time, despite the very tight timeframe. One special feature in the port of Hamburg is the automatic compensation for changes in water level, which can fluctuate by as much as nine meters and therefore requires special cable routing. The ‘AIDAsol’ is the first cruise ship to obtain its power supply via the land connection system.
