ABB to Power Two Spanish Navy Hydrographic Vessels Through Navantia Newbuilding Programme

ABB has secured a contract from Spanish shipbuilder Navantia to supply power distribution and propulsion systems for two new coastal hydrographic vessels being built for the Spanish Navy. The vessels, scheduled for delivery by 2028, will be equipped with ABB's Onboard DC Grid power system, PEMS power and energy management system, transformers, thruster motors, and batteries, designed to improve energy efficiency, operational flexibility, and reliability while reducing fuel consumption and emissions.

 

Strategic Significance of the Contract

 

The contract marks ABB's third collaboration with Navantia on Spanish Navy vessels in the past three years, reinforcing a structural relationship between two of the most established names in European naval shipbuilding and marine power systems. For naval vessels, the choice of propulsion and power architecture has long-term operational and lifecycle cost implications, since these systems shape fuel consumption, maintenance requirements, and the mission flexibility of the vessel across its operational life. The award also reflects a broader shift in naval procurement preferences toward integrated electric and hybrid power architectures, which provide improved efficiency, lower acoustic signatures, and greater operational adaptability compared with traditional mechanical drivetrains. Hydrographic vessels are particularly well suited to these architectures because their mission profile combines extended low-load survey operations with periodic higher-load transit, a profile that benefits significantly from energy-flexible electric power systems.

 

Onboard DC Grid and Integrated Power Solution

 

The core of the ABB package is the Onboard DC Grid system, complemented by the PEMS power and energy management system, transformers, thruster motors, and battery storage. The Onboard DC Grid architecture is positioned as one of the more advanced power solutions available for naval and commercial vessels, enabling more efficient integration of multiple power sources including generators, batteries, and shore power. The benefits include reduced fuel consumption, lower emissions, smaller engine room footprint, and improved operational flexibility for vessels operating across a wide range of load conditions. The integration of battery storage into the system also provides operational advantages including peak shaving, redundancy, and the ability to operate on battery power alone in selected scenarios. For coastal hydrographic vessels, these capabilities translate into improved survey performance, lower operating costs, and reduced acoustic disturbance during sensitive sensor operations.

 

Operational Implications for Hydrographic Operations

 

Coastal hydrographic vessels operate in demanding environments where energy efficiency, reliability, and operational flexibility are critical performance parameters. Survey missions often require sustained operation at low speeds with precise station-keeping, conditions under which traditional mechanical propulsion systems are inefficient and may produce vibration or acoustic interference that affects sensor performance. Electric propulsion systems with battery storage are better matched to these conditions, supporting smoother low-load operation, lower noise, and tighter control over vessel motion. The improvements directly affect the quality of hydrographic data collected, with implications for the accuracy of nautical charts, the planning of port and harbour infrastructure, and the support of safe navigation in coastal and approach waters.

Scope of ABB's Project Responsibilities

 

ABB will oversee engineering, testing, and commissioning activities related to the equipment package, providing an end-to-end delivery scope rather than supplying components alone. The integrated approach is operationally significant because the performance of advanced marine power systems depends as much on commissioning and integration quality as on the underlying hardware specification. By taking responsibility for the full lifecycle of the ABB-supplied equipment from design through commissioning, the company is able to ensure that the system performs to specification once installed on board and that any issues encountered during testing are resolved before delivery. This delivery model is increasingly common in advanced naval and commercial newbuilding projects, where integration complexity has risen alongside the sophistication of onboard systems.

 

Strategic Framing From Project Partners

 

Alberto Cervantes, director of corvettes and maritime action ships business at Navantia, has framed the collaboration as building on two previous successful engagements with ABB and emphasised that the energy efficiency, reliability, and flexibility of the Onboard DC Grid will prove invaluable in the demanding environments where the new vessels will operate. Sindre Satre, business line manager for coast guard and navy at ABB Marine and Ports, has positioned the contract as a continuation of the company's commitment to advancing naval innovation through electrification and digitalisation. The framing aligns with the broader trajectory of naval procurement, where electrification and digital integration are becoming defining features of next-generation vessel design across multiple navies.

 

Outlook for Naval Electrification

 

The Spanish Navy contract reflects a wider trend toward the adoption of advanced electric power systems across naval fleets, with implications for vessel design, operational economics, and supply chain dynamics. As more navies move to electrify their fleets, demand for integrated power and propulsion solutions is expected to continue growing, supporting the competitive positioning of providers such as ABB that combine deep marine experience with advanced electric system capability. For the broader naval shipbuilding industry, electrification trends are likely to influence both newbuilding programmes and the retrofit market, as existing vessels are upgraded to incorporate more efficient and flexible power systems. The Spanish Navy hydrographic vessel programme provides one of the more visible recent examples of how these dynamics are translating into specific procurement decisions.
