A vehicle (10) for performing operations on a subsea pipeline, such as a riser (2), carries one or more interchangeable modules (18) and is configured to translate along the riser (2). The vehicle (10) comprises an elongate support structure (12) for carrying the modules (18). Gripper arms (14, 16) hold the support structure (12) a predetermined distance away from the elongate body and cause translation of the vehicle (10) along the riser (2) using a hand-over-hand action, so as to allow the vehicle (10) to pass protuberances or obstacles, such as a clamp (8), on the riser (2).
