Tarchon Energy will first need to procure seabed and onshore surveys, which will then be used to inform procurement of the main equipment and services required to design, construct, install, and commission the project. 

These seabed and onshore surveys will provide the detailed technical information that will form part of the requirements specification against which potential equipment and service suppliers will bid. Seabed surveys will have the longest lead time due to the length of the offshore route and the requirement for sufficient windows of good weather. Two separate Official Journal of the European Union (OJEU) notices will be issued for offshore seabed surveys and onshore surveys.
