The offshore production of oil and gas plays a vital role in the energy infrastructure of many countries. However, operations relating to this production can be extremely energy intensive, with on-site power requirements ranging as high as several hundred megawatts for larger and more complex platforms.
We can provide a comprehensive suite of HVAC and HVDC cables and products for the transmission of onshore electricity to offshore platforms via submarine cable systems.
These connections are efficient in enabling a constant and reliable supply of power to offshore oil and gas platforms creating an environmentally favourable solution by avoiding the local power generation, typically diesel-based, on the platforms. As the power from the national grid is cheaper than diesel generated electricity in comparison, it’s also seen as an economically preferable option. With our end-to-end service, utilising our range of manufacturing, installation and engineering assets, we are a single source provider offering full EPCI turnkey cable system solutions to meet our customer requirements. Our full value chain sets us apart, giving our customers a hassle-free single point of contact for all their project needs.
In 2013, Prysmian was awarded a contract for the supply and installation of submarine cables for a section of ExxonMobil’s existing offshore operations in the United States. The scope of work involved the replacement of approximately 50 km of submarine power cables with increased capacity 40 kV EPR submarine cables, designed for water depths of up to 450 metres. The cables will supply electric power from the existing shore-based generating plant to offshore platforms. Installation has been undertaken by our Cable Enterprise laying vessel. The Cable Enterprise underwent significant modification work in 2014 to be converted to a full Dynamically Positioned (DP) vessel in readiness for these installation works.
