Durable Solutions

For Demanding Conditions

With the very significant duty-cycles that are often seen with commercial vessel operations, it is essential that systems are able to operate for extended periods while giving reliable service and avoiding unscheduled and expensive downtime. Halyard’s approach is to provide robust and durable bespoke, standard or tailored solutions that are aligned to these demanding conditions.

Distinctly Experienced

In meeting your needs

Halyard is uniquely experienced in meeting the needs of the commercial operator, and we supply systems into markets including:



Offshore Crew Boat


Border Patrol


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.

Our products are designed and manufactured to comply with Marine Classification Society rules and Flag State and local regulations. Our composite, rubber and silicone products are Lloyd’s type approved and all Halyard components are produced following ISO 9001:2015 processes.
