A Rittal Ri4Power switchgear and busbar system has been installed in Logos Hope, a 442-passenger ship. The ocean liner, which sails around ports predominantly in South-East Asia, Africa and the Middle East, is operated on behalf of OM Ships International, a Christian training and outreach movement, by GBA Ships e.V., a private, non-profit, charitable organisation registered in Germany.
The Ri4Power panel, which stretches 10m wide, complies with DNV marine specification and IEC 61439. The busbar system incorporates Siemens power distribution components and is rated at 5000A with incoming temporary shore power at 2000A.
Earlier this year Rittal announced that its popular busbar systems RiLine60, Maxi-PLS and Flat-PLS had passed the most stringent testing enabling them to be integrated within Ri4Power modular switchgear systems and used on board ships in designated sealed areas, such as engine rooms.
The busbars satisfied the vibration requirement of 0.7g in the frequency range 5–100Hz. They and their related components had therefore demonstrated their capability to operate in the toughest and most demanding environments in terms of: short-circuit resistance; temperature rises; dielectric strength; thermal resistance; and use under vibration conditions.
Rittal’s maritime portfolio of enclosure and case technology is proven to protect delicate, highly sensitive and complex systems across every aspect of nautical application – from shipping on the high seas, to oil and gas extraction, to port technology – in the most challenging of external conditions.
Furthermore, Rittal’s expert team can support maritime enterprises across all aspects of systems infrastructure installation from the application engineering, development supervision and prototyping phases, through to monitoring of the finished product in use.
Mark Guest, Rittal’s product manager for power says: “I’m delighted that a Ri4Power switchgear and busbar system has been installed in the Logos Hope so soon after the busbars had successfully passed their environmental ‘Vibration’ testing. It’s evidence of the confidence provided by Rittal’s long-standing experience in designing enclosure solutions for harsh ambient conditions and our assured product reliability.”
The Rittal busbar systems have been approved for shipping covered by the following international organisations: Lloyds Register (LR), Germanischer Lloyd (GL), Det Norske Veritas (DNV), and the American Bureau of Shipping (ABS).
