Circuit protection for a luxury yacht

Siemens has collaborated with Bluegame, a brand of the Italian Sanlorenzo Group specialising in the production of luxury yachts.

As an ‘Innovative Technology Partner’, Siemens helped Bluegame to develop its new BGF45 yacht, which premiered at the 2025 Cannes Yachting Festival.

A key part of the collaboration was Siemens’ semiconductor-based SENTRON ECPD (electronic circuit protection device) technology, which, in combination with other SENTRON devices, formed the basis of the BGF45’s electrification system.

Installed in the onboard electrical panels, the ECPD enables intelligent management of energy flows through integrated monitoring functions, contributing to the yacht’s overall efficiency. Moreover, its ultra-fast response in the event of a fault minimises anomalies, reducing maintenance costs and supporting operational continuity in a variety of sailing conditions.

The ECPD is also designed to be versatile, with the technology intelligently adapting to the specific needs of the vessel, adjusting configurations and responses based on different electrical loads and the varying degrees of customisation required.

“With our groundbreaking SENTRON ECPD we provide industry-leading technology to contribute to the highest levels of safety, efficiency and sustainability, even on the world’s oceans,” said Andreas Matthé, CEO Electrical Products at Siemens Smart Infrastructure.

Technological innovation was not the only goal for the companies; they were also driven by a desire for sustainability. Bluegame has stated its commitment to a comprehensive sustainability strategy encompassing environmental, social and economic pillars, while actively contributing to the UN’s 2030 Sustainable Development Goals throughout its daily operations.

The SENTRON ECPD was a good environmental fit for Bluegame, being one of the first Siemens products to earn the Siemens EcoTech label, a certification that introduces new standards of transparency in the industry and demonstrates the company’s commitment to developing environmentally low-impact solutions.

Thanks to its multifunctionality, the Siemens solution replaces numerous conventional devices with a single device, requiring approximately 85% less space in the electrical distribution board. Depending on the application, the ECPD also enables savings of up to 80% on electronics, 90% on metals and 90% on plastics, Siemens said.
