Engineering Techniques

Quality and compliance with international standards are of paramount importance in nautical engineering.

Engineering Techniques

MarQuip designs and systems fulfil all the requirements of the major class bureaus. Ours are the first and only exhaust systems to bear a Design Appraisal from Lloyd’s Register. Moreover, all MarQuip’s internal procedures are compliant with NEN-EN-ISO 9001-2015 and ISO14001:2015.

Back pressure controlBack pressure control
An essential part of our underwater exhaust systems is the ‘scoop’ or ‘cowl’. Designed by MarQuip, this special cap incorporates insights from tank tests and advanced computer models to optimise back-pressure control.

Noise attenuation controlNoise attenuation
Noise is always an issue onboard a yacht. Our acoustic experts are continuously working on optimally balanced and super-quiet systems within the parameters set by the involved parties. MarQuip offers tailor-made solutions based on the data received.

Anti vibration controlAnti vibration control
Once the layout of an exhaust is designed, we focus on reducing the vibrations transferred from the exhaust system to the vessel’s structure. This is done by placing anti-vibration mounts, compensators and rubber bellows in key positions.

Exhaust cooling controlExhaust cooling control
MarQuip fits special nozzles inside exhaust pipes to improve control over the size of water droplets, boosting the exhaust gas cooling and eliminating hot spots from the pipe. Many existing wet exhaust systems are made of the wrong materials and vulnerable to corrosion: MarQuip deploys its extensive knowledge of various types of saltwater-resistant, high-grade stainless steel to design a relatively lightweight system that is highly resistant to wear.

Emision controlEmission control
MarQuip is renowned for its green exhaust solutions. Our diesel particle filter units and Green Line Silencer (with integrated catalytic converter) unit are well integrated in most of the exhaust systems provided. Our latest innovation is the combined SCR/silencer. This new product will help ensure you are ready for IMO TIER III without any major impact on layout.
