A Deep Understanding

Of Customer requirements

Having designed and manufactured exhaust systems for both motor and sailing yachts: for propulsion engines, generators and other auxiliary engines approaching 40 years, we have developed a very detailed understanding of superyacht customer requirements. Each project is approached with the same robust methodology resulting in optimised, high quality solutions providing the customer with the reliability and peace of mind that the superyacht market requires.

Water-cooled and Dry Exhaust

For Legacy or Modern Engines

We specialise in water-cooled and dry exhaust systems and as the distributor for market leading aftertreatment solutions can also provide DPF and SCR packages for the reduction of soot and NOx. These solutions can provide IMO Tier III emission compliance as part of a certified engine package.

For environmental reasons, a DPF can also be installed for the elimination of soot as can a SCR for the reduction of NOx. Both systems are available for either legacy or modern engines.

With our significant market experience our products are designed and manufactured to comply with Marine Classification Society rules and LYC and PYC regulations. Our composite, rubber and silicone products are Lloyd’s type approved and all Halyard components are produced following ISO 9001:2015 processes.

We offer a wide range of standard and bespoke components, designed and manufactured by our in-house teams, where our scope of supply covers complete exhaust systems down to individual components. So, whether the requirement is a sophisticated bespoke water-cooled or dry complete exhaust system including aftertreatment package or a replacement spray ring, silencer, separator, hose or bellows, Halyard has the solution.
