Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the fatal incident on the Valaris 121 jackup drill rig on 14 November 2025, whether the Maritime Accident and Investigation Branch (a) registered the UK as a Substantially Interested State and (b) provided assistance to the Liberian Shipping Registry.

The Marine Accident Investigation Branch (MAIB) is aware of the accident on the Valaris 121 jack-up drilling rig that occurred on the 14 November 2025. The MAIB has been in contact with the Liberian Ship Registry and received confirmation that the registry is conducting a preliminary assessment into the incident, which is in the evidence gathering phase.

As Valaris 121 was jacked-up, immobile and carrying out drilling operations, its operations fall under the purview of the Health and Safety Executive (HSE) Offshore. The MAIB has received confirmation that HSE (Offshore) has commenced an investigation into the accident, and HSE’s contact details have been passed to the Liberian Ship Registry.
