MAN Energy Solutions' retrofit concept consists of a broad range of solutions where our PrimeServ after-sales division applies the latest technologies to propulsion systems - in the process bringing them up to current standards and meeting modern emission levels and lowered running costs. The concept applies to all MAN Energy Solutions engines (both marine and stationary), propellers, aftship and turbochargers. It can even be applied to propulsion systems from other manufacturers and has multiple benefits for vessels and shipowners.

    Propeller Upgrade

    The propeller and aft ship are attractive areas for retrofit and upgrade investments - with very short payback time, which will clearly optimise your operational economy. Based on state-of-the-art CFD analysis, design and optimisation tools MAN PrimeServ offers a wide range of fuel-saving solutions covering FPP’s, CPP’s and Efficiency Improving Devices.

    Slow Steaming

    You can achieve substantial fuel oil savings by reducing vessel speed from e.g. 25 to 20 knots. Even greater savings can be made with an engine load of just 10%. MAN PrimeServ offers a range of retrofit solutions for efficient low-load operation of two-stroke diesel engines that also allow the flexibility of full-speed operation when required.

    Efficiency Improving Devices

    In connection with retrofit and upgrade solutions, the propeller and propulsion efficiency can be further improved by means of selected Efficiency Improving Devices. MAN PrimeServ offers a wide range of solutions, which translates directly into a reduction in fuel consumption, emissions and operational costs.
