The SERPENT Project carried out two visits to the Transocean Sedco 712 at Hurricane Energy’s Lancaster Horizontal appraisal well in summer 2014. This was the latest in a series of SERPENT missions to this area, west of Shetland in collaboration with Hurricane Energy. These studies documented the fauna inhabiting the seabed at Lancaster before and after drilling. The study included a pre-drilling and post-drilling component. This work is the latest in a series of visits to three of Hurricane Energy’s drilling locations to study biodiversity and disturbance. The results are also important as part of a wider effort to study of deep sea ecology in the areas west of Shetland and the Norwegian Sea.
