Welcome to GD Engineering

Established in 1944, GD Engineering has gained a worldwide reputation for pioneering work in the design and manufacture of advanced pipeline access and pigging solutions. Serving the oil/gas, petrochemical and industrial processing sectors, as well as the emerging biofuels industry, we are instrumental in helping our customers to maximize their investment in pipeline infrastructure by facilitating any necessary maintenance or upgrade work.

Our quick-opening closures enable rapid access (either vertically or horizontally) to vessels once they have been depressurized. This can be done without the need for any special tools, and while ensuring complete safety for field operatives through a series of proprietary protection mechanisms. These state-of-the-art closures are capable of dealing with even the highest levels of pressure.

Suitable for both onshore and offshore deployment, our pig signalling solutions allow the accurate monitoring of pigs/scrapers while carrying out cleaning or inspection activities, so that the precise location of any potential problems can be determined. These are accompanied by high-reliability pig launching systems, which are suitable for both surface level (topside) and subsea application scenarios, and do not impinge on the pipeline flow. All our products can be supported by comprehensive project managed maintenance schemes.
