New: Compact gas valve train for safe and efficient propulsion

Stepping on the gas on the world’s oceans with SAACKE

For a long time, the use of natural gas for ship propulsion was considered very impractical compared to heavy fuel oil. The risks of leakage and lack of space for the required infrastructure seemed too great. In the meantime, shipowners and operators of tankers, FPSO systems, cruise giants and other ships with dual-fuel boilers are now increasingly investing in the clean fuel. On the one hand, this is attributable to tightened emission guidelines, and on the other hand to falling prices and increasingly intelligent technical solutions for safe and efficient gas storage and use. For example, a Gas Valve Unit (GVU) is a clever alternative to intricate gas treatment in a facility specially designed for this purpose. SAACKE has developed such a compact valve assembly “Made in Germany”, thus enabling the use of natural gas on ships and offshore facilities in accordance with the latest regulations.

The trend towards gas as a propulsion fuel led the IMO and the classification societies to adopt new rules: The International Code of Safety for Ships using Gases or other Low-Flashpoint Fuels (IGF) for dual-fuel applications on cruise ships or container ships as well as the International Code for the Con-struction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC) for LNG tankers, for exam-ple, have made explosion protection measures a compulsory part of ship equipment in gas operations and define their design criteria. The SAACKE GVU completely fulfills these requirements.

Comfortable plug-and-play product
The GVU includes zone 1 explosion protection according to ATEX 2014/34/EU. Even the slightest risk of explosion is therefore de facto eliminated. Gas quantity measurement can be performed in different ways (by turbine meter, thermal flow meter, or mass flow meter) and thus be adapted to the individual needs of the customer. In addition to the optimally adapted exhaust fan, this SAACKE development features gas detectors that can be integrated into the vessel‘s higher firing and gas system. As a convenient plug-and-play product, the gas valve train is delivered completely pre-assembled – both for new vessels and retrofits. In addition, SAACKE also supports the perfect gas-fired operation of ships and offshore systems by means of global and around-the-clock after-sale service.
