ABB extends lifespan of Helsinki ferry by retrofitting

The M/S Suomenlinna II has made history as the first vessel to be retrofitted with ABB’s cutting-edge ACS880LC drive system. This upgrade promises to enhance the ferry’s operational efficiency and reliability for years to come. Operating year-round between Helsinki’s Market Square and the UNESCO World Heritage site of Suomenlinna, the ferry plays a crucial role in the city’s public transport network.

Modernization of a Vital Transport Link

The M/S Suomenlinna II, a 33.8-meter-long ferry, is one of three vessels operated by Suomenlinnan Liikenne Oy, a subsidiary of Helsinki City Transport. With a capacity to carry 395 passengers, the ferry makes multiple daily trips to the historic Suomenlinna sea fortress, which is not only a popular tourist destination but also home to around 850 residents. Built in 2004, the ferry was originally equipped with an ACS600 drive system that had become outdated.

To address this, ABB implemented a module-based retrofit, allowing for the replacement of only the necessary components while reusing existing cabinets, busbars, and cables. This approach minimized disruption to the ferry’s operating schedule, ensuring that it could continue to serve passengers without significant delays. ABB will also provide ongoing service support throughout the product lifecycle, further enhancing the ferry’s operational reliability.

Petri Öhrmark, Managing Director of Suomenlinnan Liikenne Oy, emphasized the importance of this modernization project. “ABB’s ability to provide a module-based retrofit as opposed to a full system replacement was a key factor for us in selecting a partner,” he stated. The upgrade is expected to ensure that the ferry continues to deliver efficient and dependable service to both residents and tourists visiting the heritage site.

Commitment to Sustainable Operations

ABB’s Head of Sales for Marine Service & Digital in Finland, Ilmari Ackley, expressed pride in being selected for this modernization effort. He noted that the project was executed smoothly and on schedule, which is vital for a ferry that serves hundreds of passengers daily. The module-based retrofit not only enhances the ferry’s technology but also contributes to the sustainability of operations by improving circularity.

This upgrade reflects a broader trend in the maritime industry, where companies are increasingly focused on integrating advanced technologies to enhance efficiency and reduce environmental impact. The successful retrofit of the M/S Suomenlinna II stands as a testament to ABB’s commitment to innovation and sustainability in marine transport.
