Barclay Engineering has decades of experience delivering marine exhaust, HVAC, and ventilation systems for a wide range of vessels operating in demanding marine environments. Our solutions are trusted across Australian offshore patrol vessels, fast ferries, luxury yachts, and specialised commercial craft, where reliability, acoustic performance, corrosion resistance, and compliance are critical.

Engineered for Marine Performance. Proven at Sea

From initial design through to fabrication and supply, Barclay Engineering provides engineered systems that support vessel performance, crew comfort, and long‑term serviceability.

Marine Ventilation Systems

With today’s high‑performance diesel and gas turbine engines, the design of engine room and machinery space ventilation packages is more critical than ever. Effective ventilation is essential for heat management, combustion air supply, personnel comfort, and safe vessel operation.

Barclay Engineering designs and supplies complete turnkey marine ventilation packages, or individual system components, tailored to project‑specific requirements.

Our marine ventilation systems may incorporate:

  • Impingement and moisture elimination filtration systems
  • Supply and exhaust fans
  • Circular and rectangular absorptive silencers
  • Weatherproof ductwork and associated components

Ventilation packages are engineered to maintain required airflow rates while meeting stringent marine noise and vibration limitations. Careful selection of fan and silencer combinations ensures acoustic compliance without compromising thermal or airflow performance.

A wide range of materials is available including polypropylene, galvanised steel, aluminium, and stainless steel, enabling optimal durability and service life in corrosive marine environments.


Marine Exhaust Systems

Barclay Engineering designs and supplies complete marine exhaust systems engineered to suit vessel‑specific layouts, engine types, and operational profiles. Systems can be configured using reactive and/or absorptive silencers, manufactured from mild steel or stainless steel, to meet both performance and acoustic requirements.

Our exhaust solutions are designed to manage:

  • High exhaust gas temperatures
  • Back‑pressure limitations
  • Hull penetration requirements
  • Noise and vibration control

To support exhaust cooling and safe discharge, Barclay Engineering designs and manufactures a range of water injection units. These systems utilise engine cooling water to cool exhaust gases and associated components as they pass through the hull—enhancing system longevity and operational safety.


In‑House Design & Australian Fabrication

All marine HVAC, ventilation, and exhaust systems are designed and drafted in‑house by Barclay Engineering’s experienced engineering team. This ensures full control over system performance, constructability, and marine compliance.

Fabrication is undertaken at our Canning Vale, Western Australia facility, where we manufacture high‑quality components designed to complement marine ventilation and exhaust systems, including:

  • Moisture eliminators
  • Weatherproof and marine‑rated louvres
  • Acoustic personnel doors
  • Engine room ventilation
  • Pressure vessel design and fabrication
  • Exhaust and ventilation silencers
  • DINAK gas turbine exhaust systems

These products are engineered for marine service, with a focus on corrosion resistance, acoustic performance, and ease of integration into vessel structures.


Experience Across Diverse Vessels

Barclay Engineering’s marine solutions have been delivered across a broad range of vessel types, including:

  • Australian offshore and patrol vessels
  • High‑speed and fast ferry vessels
  • Luxury yachts and superyachts
  • Commercial and specialised marine craft

Our experience across diverse marine applications allows us to tailor each system to the vessel’s operational duty, space constraints, and regulatory requirements.


Defence Marine Applications

Barclay Engineering has long‑standing experience supporting defence maritime programs, delivering HVAC, ventilation, and exhaust systems for offshore patrol vessels (OPVs), landing craft, and specialised defence vessels operating in demanding operational environments.

Our defence solutions are engineered to meet stringent performance, acoustic, safety, and durability requirements, with careful consideration given to shock, vibration, space constraints, redundancy, and maintainability. Systems are designed to ensure reliable engine room ventilation, effective thermal management, and controlled noise and signature levels to support both crew welfare and mission readiness.

With in‑house engineering and Australian fabrication at our Canning Vale facility, Barclay Engineering provides trusted, compliant systems tailored to defence specifications and long‑term operational support requirements.


Commercial Marine - Global Experience

Barclay Engineering also delivers marine exhaust, HVAC, and ventilation solutions to the global commercial marine sector, supporting vessels operating across international waters and diverse climatic conditions.

Our experience includes systems for:

  • Fast ferries and passenger vessels
  • Commercial workboats and service vessels
  • Specialist and multi‑purpose marine craft
  • Luxury yachts and high‑end commercial vessels

Commercial marine systems are engineered for efficiency, durability, acoustic performance, and corrosion resistance, ensuring reliable operation and passenger comfort while minimising lifecycle costs. Modular designs support world‑wide deployment, simplified installation, and ease of maintenance regardless of vessel location.

With decades of experience and proven systems installed globally, Barclay Engineering is a trusted partner for commercial marine projects requiring robust engineering, consistent quality, and dependable performance at sea.
