Why are UPS systems important in maritime installations?

Modern vessels depend on stable and reliable power. Navigation, automation, communication, data networks, control systems and emergency lighting must continue to operate during disturbances, voltage deviations or loss of the main power supply.

This makes the UPS system an important part of the vessel’s technical infrastructure.

A maritime UPS solution must do more than provide backup power. It must operate in a demanding environment, fit within the vessel’s technical framework and support critical systems over time.

Anda Power Solutions is developed for installations where standard UPS solutions are not always sufficient. The solutions combine operational reliability, compact design, flexible adaptation and practical installation in demanding maritime environments.

Developed for demanding maritime environments

Maritime installations place high demands on electrical systems.

UPS systems on board often need to operate in environments with:

• limited space
• vibration
• humidity
• salt exposure
• dust
• heat
• demanding service conditions
• documentation and classification requirements

These conditions affect how the UPS solution should be engineered, installed and maintained.

Anda Power Solutions is based on Anda-Olsen’s long experience from maritime installations. The solutions are developed for projects where the UPS system must be adapted to the vessel’s technical layout, while supporting critical loads and predictable operation.

Why ship designers value compact UPS solutions

For ship designers, space, weight, cable routing and system integration are important factors.

Technical rooms, cable routes and equipment spaces are planned carefully. A UPS solution that requires extensive space, separate components or complex infrastructure can create challenges early in the design phase.

Anda Power Solutions can help simplify this process through compact, project-specific UPS solutions that are easier to integrate into the vessel’s technical layout.

For ship designers, this can provide:

• more flexible equipment placement
• better use of limited technical space
• easier coordination with other onboard systems
• reduced need for separate rooms or distributed components
• clearer documentation of the complete solution

The value is not only in the UPS itself. It is in how the complete solution fits into the vessel.

Why shipyards value easier installation

For shipyards, much of the work is about execution, coordination and predictability.

A UPS solution that is easy to install can reduce complexity during the build process. Integrated solutions can also reduce the number of separate components, cable routes and supplier interfaces that need to be coordinated during installation.

Anda Power Solutions can be adapted to project requirements for voltage, capacity, backup time, distribution, cabinet design and documentation.

For shipyards, this can provide practical advantages such as:

• easier installation planning
• fewer separate components to coordinate
• reduced cabling requirements
• easier connection to surrounding systems
• better overview during commissioning and handover

In newbuild projects, early clarification of UPS requirements can help reduce late-stage changes. In retrofit projects, compact and adapted solutions can make it easier to replace or upgrade existing systems within the available space.

Why installers prefer integrated UPS solutions

Installers need solutions that are clear, practical and efficient to connect.

In maritime projects, complex cabling, limited access and multiple supplier interfaces can increase both installation time and the risk of errors. A more integrated UPS solution can reduce this complexity.

Depending on project requirements, Anda Power Solutions can combine UPS, batteries, distribution, alarm functions and project-specific cabinets in one more complete solution.

For installers, this can mean:

• fewer interfaces
• less cabling
• easier connection
• clearer system boundaries
• more efficient installation
• easier troubleshooting during commissioning

A well-integrated UPS solution also makes it easier to understand how the system is built and how it interacts with the rest of the vessel’s electrical installation.

Why shipowners focus on operational reliability and lifecycle value

For shipowners, the most important factor is that the system supports stable operation over time.

A UPS system should protect critical functions, reduce operational risk and be possible to maintain throughout the vessel’s lifetime. The solution should also be adapted to the vessel’s actual load profile, required backup time and operational requirements.

Anda Power Solutions is relevant for shipowners because the solutions can be adapted to different maritime installations, both in newbuilds and existing vessels.

Important priorities for shipowners often include:

• high uptime
• predictable operation
• good service access
• spare parts availability
• flexible system adaptation
• documentation for maritime projects
• lifecycle support

The value of a UPS solution is therefore not measured only at installation. It is measured through many years of operation.

Why crew need clear and service-friendly systems

For the crew, the UPS system must be understandable, accessible and practical to work with.

A compact and integrated solution can make it easier to access key components, perform inspections and understand the system layout. This is particularly important on vessels where technical spaces are tight and maintenance often has to be carried out under demanding conditions.

For the crew, a good UPS solution should support:

• clear system overview
• practical access for inspection
• easier maintenance
• reduced operational complexity
• clearer handling of deviations or faults

When critical power systems are easier to understand and follow up, the crew is better positioned to maintain stable and efficient operation on board.

Compact UPS solutions for limited onboard space

Space is one of the main practical challenges in maritime UPS installations.

Technical rooms are often heavily utilised, cable routes are limited, and critical systems must be positioned so they can be installed, operated and maintained over time.

This is why compact UPS design matters.

A compact UPS solution is not only about smaller physical size. It is about simplifying the complete installation by considering UPS, batteries, distribution, cabinet design, service access and documentation as one integrated solution.

This can help reduce:

• unnecessary cabling
• separate components
• complex supplier interfaces
• installation time
• space conflicts
• future service challenges

In maritime projects, compact design and flexible adaptation can be decisive for how well the solution works in practice.

Different vessels require different UPS solutions

No two maritime projects are exactly the same.

A newbuild has different possibilities than a retrofit project. A smaller vessel has different space limitations than a larger offshore vessel. Some installations require single-phase UPS systems, while others require three-phase UPS systems, DC systems or customised battery solutions.

The UPS solution should therefore be dimensioned and designed according to the actual needs of the project.

Important factors include:

• load profile
• required backup time
• available space
• voltage
• AC or DC requirements
• environmental conditions
• enclosure rating
• distribution
• service access
• documentation and classification requirements

Correct adaptation helps reduce complexity and supports operational reliability over time.
