With decades of natural gas measurement and control experience, Honeywell has developed an advanced gas valve unit with axial, high-capacity regulators and safety valves housed in a gas-tight enclosure. This Enclosed Gas Valve Unit (E-GVU) is a compact plug & play solution, adaptive to any marine engine control system and enables full utilization of the vessel’s engine room with significant space and cost savings.

Compact Design. Robust Performance.

The marine gas business is demanding. Service organizations need a proven solution to control, regulate and measure liquefied natural gas (LNG) for vessel propulsion. Stringent environmental regulations on emission control and an expanding LNG-infrastructure are driving a market shift towards gas as an alternative to marine diesel oil (MDO) and heavy fuel oil (HFO).

Easier Installation

Honeywell’s innovative E-GVU enables marine operators to design a gas train with significantly reduced space requirements. It provides a gas-tight enclosure around process components, including valves, regulators, actuators and sensors. This solution allows the unit to be installed close to the engine, similar to other auxiliary equipment. No dedicated GVU room is necessary, reducing costs for both the yard and owner. Savings are also achieved in the control system architecture.

Precise Pressure Control For each gas-fueled engine on a marine vessel, the gas supply pressure has to be adjusted within a narrow, load-dependent pressure range. The ability to locate the E-GVU next to the engine reduces the gas volume between the pressure control valve and the engine itself, which improves the response time of the system during transient conditions such as engine load fluctuations.

Improved Ship Safety

The E-GVU can improve the safety of LNG-powered vessels, as stipulated by the Interim Guidelines on Safety for natural gas-fueled engine installations on ships (IGF code). The main functions of the device are to regulate gas-feeding pressure to the engine, and to ensure a fast and reliable shutdown of the gas supply.

With Honeywell’s approach, ventilation requirements are significantly reduced, compared to large dedicated GVU rooms, enabling faster and earlier detection of even the smallest gas leakage. Users also benefit from smaller hazardous areas and easier class approval.

Greater Confidence

The complete E-GVU system undergoes a factory acceptance test (FAT) with the marine engine control system before delivery, thereby providing the confidence of a high-quality and trouble-free commissioning.
