• Back pressure limits
• Outlet positions and pipe runs
• Noise levels needed
• Design, delivery, installation and launch schedules
Our team will support you through this process and all have extensive experience of projects large and small, refit and new build.
We’ll agree a timetable working backwards from a charter commitment with a complex refit in the meantime, or forwards on a new build where the keel has yet to be laid. Your timetable becomes our priority.
We will sit down and understand the priorities of the Crew, the Yacht Managers, the Designers, the engine and generator suppliers and their warranty needs, exhaust system running hours and lifetime needs, the Shipyard involved, and the Classification Society. We understand the need for balancing all these requirements at this early stage, to ensure that everyone’s views are reflected as the specification and design emerges.
From this consultation we will develop a project plan, a design brief, and the beginnings of an exhaust system.
• Pipe runs and main water injection components
• Silencers and outlets
We will liaise with you as questions emerge during this phase, be they engine requirements or vessel layout points. Agreement of the initial system layout is a key gateway in the process – a plan to which we all commit, and one which enables development of a specification against which a system can be agreed.
• Pipe runs, back pressures and safety against water-line risk
• Water injection spray head design and positioning
• Bypasses where below water outlets are involved
• Water separation on generator systems
• Silencer attenuation, and the way this fits to the overall objective
• Silencer design, wet or dry, inlet and outlet positioning and dynamics
• Vibration control and the need for heat resilient mountings, stabilizers, bellows and insulation
• Exhaust gas cleaning for generators
Design sign-off – the detail of every component – releases the entire system to Halyard facilities for production.
• Completing manufacture of the entire system
• Liaising on delivery, understanding and agreeing the fitting process
• Supporting the installation team solving questions as they emerge
• Inspecting the completed work as agreed
• Attending sea trials to assess function and fulfilment of warranty criteria as agreed
Manufactured components feed into our central despatch and packed as an entire exhaust system. Each item is checked finally for dimensional accuracy and quality before being palletised for shipping by road, sea or air to the timetable agreed with the vessel or yard.
Our project management team then work with the Shipyard or Crew to an agreed level of involvement through the installation. Frequently we’re asked to visit during the installation process to oversee and check in a more detailed manner- you choose. We agree the level of involvement at the outset, giving support which will vary with the complexity of the project but is designed to ensure success from the moment the engines are first started.
On sea trials we work alongside Shipyard, Crew, engine and generator suppliers and any classification society surveyors to check through the function of the exhaust, monitoring back pressures, temperatures and assessing noise levels.
Our aim is to ensure the installation is fully functional and to specification; and will be the foundation of service and support into the future.
• Email and phone support over the first few months
• Advice and help with any problems should they emerge
• Support with rapid replacements of service components
• Drawing archives giving us immediate access to every component on board
We started our business in 1979 and we have grown with our market and customers during this time. We have an extensive list of customers that we have built long lasting relationships with based on our ability to understand their requirements and our ability to deliver the solution on time and to budget. Not only are our customers supported by Halyard, but also an increasing number of distributors that are spread world-wide.
We recognise that service is everything and Halyard delivers this.
