The very first MAN Diesel & Turbo TCA77 turbocharger installed aboard ‘Jo Sequoia’ nears 50,000 hours trouble-free operation. The chemical tanker 'Jo Seuoia' is powered by a MAN B&W 7S50MC-C two-stroke engine, having been built about ten years ago for Bergen-based Jo Tankers. During its construction, and with Jo Tankers already having chosen an MAN B&W 7S50MC-C engine as prime mover, MAN Diesel & Turbo approached Jo Tankers in regard to installing its then-new TCA77 turbocharger.
