Gas & Flame Detectors Receive DNV-GL and MED Marine Approvals

Gas & Flame Detectors Receive DNV-GL and MED Marine Approvals Our most popular advanced gas and flame detectors now meet the Marine Equipment Directive (MED) for Det Norske Veritas’ (DNV) Offshore Standards as well as DNV·GL Type Approval. They are now approved for a wide range of gas and flame safety applications in marine environments aboard floating production storage and offloading (FPSO) vessels, LNG tankers, offshore production platforms, port loading/unloading stations, offshore refining operations and more.

Designed to support offshore deepwater oil & gas production, FPSO vessels require extensive gas and flame monitoring. The compact shipboard environment is much the same as an offshore production platform, which means that even the smallest of hazards can become a big problem quickly.

FPSO vessels take on oil & gas from subsea production fields where it is processed on the upper decks and then stored below where it is protected by the ship’s hull. The ships are generally moored in place or can return to port periodically. Visiting tankers typically service FPSO vessels for unloading and then return to port with the contents, which from there are transported by pipeline or stored in large tank facilities. Operation precautions are also necessary with LNG tankers to protect their crew and the vessel from hazardous gas leaks and fires.

The various tightly located crude oil & gas processing and storage areas aboard FPSO vessels all require gas and flame detection. The oil processing areas include water separation, gas separation, oil processing, etc. The oil is then stored and can be offloaded to visiting tankers, which allow the FPSO vessel to remain in place. All of these operation areas are hazardous and require an abundance of precaution with fire and gas systems.

The marine environment poses special challenges for electronic devices such as gas and flame detectors. Continuous exposure to humidity, salty air, extreme temperatures, etc., can be corrosive or lead to the build-up of films on detector surfaces unless the proper detector design and materials are chosen. In addition the size, weight, installation space necessary, and maintenance needs are all concerns with every piece of equipment placed aboard marine vessels of any kind. With over 50 years of oil & gas industry experience, we understand these marine industry application requirements and have engineered our gas and flame detectors to meet them.

To this end, we have obtained DNV·GL Type Approval to ensure qualification for use in all marine markets. The following products are DNV·GL Type Approved:
FL4000H MSIR Flame Detector
S4000CH Combustible Gas Detector
IR400 Point IR Gas Detector
IR4000S Single-Point Gas Monitor
IR5500 Open Path Infrared Gas Detector
Gassonic Observer-i Ultrasonic Gas Leak Detector

DNV·GL is the world’s leading ship and offshore classification society, the leading technical advisor to the global oil and gas industry and a leading expert for the energy value chain including renewable and energy efficiency. It is one of the top three certification bodies in the world.

Similarly, MED is the European Directive requiring that gas and flame detectors that are to be installed in marine environments be tested to specific standards. Once suppliers meet these specific standards through rigorous testing, their products are then eligible to be inscribed with the “wheel mark” of approval. The wheel mark indicates that the products have passed testing to industry standards and are deemed safe and certified for use in marine applications/environments.

The General Monitors gas and flame detectors that now carry the MED wheel mark include the following:
FL4000H Multi-Spectrum IR Flame Detector
S4000CH Combustible Gas Detector
IR400 Point IR Gas Detector
IR4000S Single-Point Gas Monitor

The Model FL4000H Multi-Spectrum IR Flame Detector is an advanced multi-spectrum infrared (MSIR) flame detector. It is designed to provide superior false alarm immunity with the widest field of view for superior protection.

The S4000CH Combustible Gas Detector is a microprocessor-based transmitter designed for use with General Monitors' robust catalytic bead sensors. The Model IR400 Infrared (IR) Point Detector is a hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication. The Model IR4000S Single-Point Monitor is a display and user interface for the IR400 IR Point Gas Detector.

The Gassonic Observer-i Ultrasonic Gas Leak Detector instantly detects pressurized gas leaks. It features artificial neural network (ANN) technology that distinguishes real gas leak noise from background noise to prevent false alarms.

These new marine approvals assures customers that our gas and flame detectors have been independently tested and found to meet the highest industry standards while supporting the values of safeguarding life, property and the environment worldwide.
