What we do

Challenge

This project entailed the transport and installation of a natural gas processing offshore facility to treat the gas from the Q10-A field, located 26 km off the coast of Ijmuiden with the HGLJV 'Apollo'. The Q10 platform is a Minimum Facility Platform of Tulip Oil, which is designed to extract gas and perform basic processing such as water removal.

With three windmills, a wall of solar panels and battery pack, the platform is entirely self- sufficient. Furthermore, the platform is unmanned and equipped with all the technology required for full remote control.
