Cleaner, greener, quieter: new bypass soot filter

Manoeuvring in closed-in locations, like marinas, a yacht’s engines operate in part-throttle mode, with the exhaust system emitting gases above the waterline via a bypass. This inevitably leads to the emission of particulates into the air and onto the hull, while the noise levels are higher than those generated below the waterline. Our engineers have been looking into a solution for tackling these challenges with some very promising results.

MarQuip has developed a smart new solution that will make owners and captains a little more popular when their yacht is manoeuvring without having to fit a large soot filter to the main engines. This concept for a significantly smaller and more cost-effective bypass soot filter will neutralise above-the-waterline diesel particle pollution and be much quieter, offering a win-win situation for people and the environment alike.

This solution can be integrated onto existing yachts as well as new builds. The system can even be combined with custom-built third-party Selective Catalytic Reduction (SCR) installations. The Diesel Particle Filter (DPF) system is fitted with a smart control unit that can act on various parameters such as the backpressure, speed and RPMs of the engines.

The DPF can be kept relatively small as the amount of exhaust gases when manoeuvring – usually at a maximum of 20% throttle – is significantly less than when going full speed ahead. But it will offer an impressive amount of protection against fouling your hull as well as radically reducing any fume inhalation by crew members on deck. This solution is also impressively quieter than a traditional bypass, removing the rise in noise levels experienced when switching from below to above the waterline.
