Solutions for Methanol operations
The methanol system is equipped with complete automation
Auramarine Methanol Supply System supplies methanol to the Master Fuel Valve whilst and at the same time regulating the flow, pressure and temperature of the methanol. All this, combined with filtration, ensures the system is suitable for most type of engines and other methanol consumers. The system actively maintains the supply pressure within the specified tolerances during load changes and is designed to meet the strict safety requirements.
The system supplies methanol all the way from bunkering station to the engines and other consumers. And it is designed to support efficient onboard arrangement and to fit the space available. Auramarine methanol system is suitable for both two-stroke and four-stroke engines.
Combining the best of nature and technology
Our systems are based on clean and renewable fuels. Auramarine's state of the art methanol fuel supply systems are modular and efficient, ensuring safety, reliability and continuity by combining the best of nature and technology.
A viable option for decarbonisation
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.
Auramarine methanol fuel supply system includes:
- Fuel supply to consumer
- Fuel consumption measurement
- Pressure control
- Temperature control
- Filtration
- Shut-off valves for safe maintenance
- Automatic draining and inerting
- Fuel valve train and water injection as option.
Methanol fuel supply system 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 all components and electric equipment will be specially selected for use in a hazardous area.
In order to minimize the electrical equipment in a hazardous area, the electrical cabinets, control panels and variable frequency drives are designed to be fitted separately to a safe area.
Seamless backup for methanol operation
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.
Because Auramarine HFO and MGO units are built to always maintain the engine-specific fuel temperatures and other requirements. These units are suitable for backup purposes and they are already trusted and proven in current LNG-operated vessels.
When selecting both the methanol fuel supply system, backup fuel system and pilot fuel system from same supplier brings the following synergies and benefits:
- Smoother project administration for shipyard at the shipbuilding stage
- The design can be optimized for the exact space available
- All documentation is from one supplier at the same way
- One contact point for all the equipment
