The Auramarine Methanol Supply Unit supplies methanol from the service tank to the Master Fuel Valve whilst and at same time regulating the flow, pressure and temperature of the methanol. All this, combined with filtration, ensures it is suitable for engines and other methanol consumers. The system actively maintains the supply pressure within the specified tolerances during load changes.

decarbonisatio可行的选择n

Methanol is one of the most viable clean fuels to cut greenhouse gas emissions and help meet global decarbonisation targets. Indeed, full carbon neutrality can be achieved by using “green methanol”. Methanol also reduces other emissions such as SOx, NOx, and particulates compared to diesel oil.

With the energy efficiency design (EEDI) and emissions reduction requirements in mind, the use of methanol as a maritime fuel is likely to gain momentum.

Safety

All fuel supply system materials and manufacturing procedures need to be suitable for methanol service and for the specifications of a particular application. The unit is designed to fit on closed and Ex rated hazardous areas.All IECEx and Health and Safety Guidelines (HSE) have been taken into account.

This level of safety is achieved by using self-draining mechanical design in conjunction with the nitrogen inerting process and double block and bleed configurations to any serviceable methanol line segments. Also allcomponents and electric equipment will be specially selected for use in a hazardous area.

In order to minimize the electrical equipment in a hazardousarea, the electrical cabinets, control panels and variable frequency drives aredesigned to be fitted separatelyto a safe area.

Seamless backup for methanol operation

Critically, for dual fuel engines operating on methanol there is always a backup system that kicks in immediately if a disturbance is detected in the methanol combustion.

开云体育在线登录入口官网下载 HFO and MGO units are suitable for backup purposes and they are already trusted and proven in current LNG-operated vessels. 

These units are built to always maintain the engine-specific fuel temperatures and other requirements.

Selecting both the methanol fuel supply system, backup fuel system and pilot fuel system from same supplier brings the following synergies and benefits:  

• It is straightforward to buy and administrate from a shipyard perspective at the shipbuilding stage 
• The design can be optimized for the exact space available 
• All documentation is from one supplier, which brings benefits in operation
• There is one contact point for all the equipment 
• If a service is needed, our service engineer can check the status of all equipment at the same time for safe and reliable operation.
