The age of Imo Tier III

24 sep 2015

MarQuip has played a major role in ensuring new superyachts will meet IMO TIER III legislation regarding NOX reduction when it comes into force next year. Our pioneering clean exhaust system is one of the main topics of discussion at our stand (QAB7) at the Monaco Yacht Show.

As a leading designer and manufacturer of superyacht exhaust systems, MarQuip was well ahead of the game with respect to the new IMO emission regulations. In 2014 we introduced an innovative solution that combines a Particle Diesel Burner, silencer/muffler for noise level compliance and, when requested, a Selective Catalytic Reduction (SCR) unit and heat exchanger.

The system was welcomed by owners faced with the conflict between performance and environmental considerations.

While the new IMO TIER III regulations are compulsory for yachts for which the keel is laid in 2016 onwards, owners can choose whether to upgrade their existing yacht.. Environmental awareness is rising sharply, however, as we have seen by the many requests received for information about our clean exhaust system. And IMO TIER III compliance applies fully to refits if the engines are modified or replaced.

The MarQuip R&D team has charted what it takes to make an existing yacht TIER III compliant.

An adjustment of this magnitude requires accurate and efficient work. We first make an on board survey: examining the existing exhaust system, engine room and tank layout, making 3D scans of the engine room and interfaces, and collecting the necessary data on design, engine performance, fuel capacity, quality and operational conditions.

The 3D scan is then transferred into usable drawings and a new exhaust layout is designed incorporating the SCR system. MarQuip provides a report on operational costs, a detailed quotation for design, supply, installation, commission and certification, and the preliminary planning.

By proceeding in a clear and orderly way, we can design a solution that fits the bill in both a physical and budgetary sense. The MarQuip clean exhaust system meets the new requirements of IMO and the high standards of owners.
