CUI Global technology receives ABS certification

LNG Industry,

CUI Global Inc.’s GasPT2 technology has received certification for use offshore and in the marine industry, specifically for use onboard natural gas tankers, from the American Bureau of Shipping (ABS).

The certified GasPT2 system was designed in collaboration with Cryostar and ABS. It is intended to take a sample of pressurised natural boil-off gas (NBOG) and provide composition data, which is then fed into the ship's Distribution Control System (DCS). The data is used to optimise the performance of the re-liquefaction process, it incorporates specialised cryogenic equipment and CUI Global's subsidiary, Orbital Gas Systems Ltd's (Orbital-UK), in-house bespoke engineering of critical components to satisfy the key challenges for the marine environment, whilst ensuring operator and system safety.

LNG applications

Cryostar is a recognised expert in advanced technologies for industrial gas, clean energy, LNG and hydrocarbon applications. In a recent project, Cryostar was looking to enhance the control of its proprietary EcoRel re-liquefaction plants. These plants are typically used on LNG carriers fitted with 2-stroke slow speed diesel engines, which do not consume the NBOG and therefore require a means to maintain safe cargo tank conditions and re-liquefy the NBOG using the data provided by the GasPT2 to optimise the performance of the re-liquefaction process.

Cryostar was attracted by the robust and ‘fit and forget’ nature of the GasPT2 design, as the ships crews may not have the specialised technical knowledge to maintain other types of analysers, especially those requiring periodic re-calibration.

Orbital-UK is now in the process of delivering to Cryostar the first four systems for use on-board new LNG carriers.


CUI Global CEO, William Clough, commented: "Receiving this certification from such an iconic organisation as ABS, allows the company to aggressively enter yet another market with its unique natural gas technology. Meanwhile, our immediate delivery of units to Cryostar and its adoption of the GasPT2 solution ensure our credibility and viability in the growing marine and offshore natural gas markets."

The certification can be found on the ABS website ( and via Certificate No. 13-LD1105876-PDA.
