Abstract: A method of drilling a bore at a subsea location is provided, the method comprising providing a remotely operated drilling assembly at a subsurface location; providing a conduit extending from the surface of the water to the remotely operated drilling assembly; and drilling the bore at the subsea location using the remotely operated drilling assembly. An apparatus for conducting a drilling operation at the seabed comprises a remotely operable drilling assembly deployed at a subsea location; and a conduit extending from the drilling assembly to the surface of the water.

Abstract: A jack-up vehicle having a hull including at least two hull sections (2, 3) interconnected in such manner as to be positionable in an end-to-end relationship having a first vehicle width and for the purpose of movement of the vehicle from one location to another location and to be positionable in a side-by-side configuration having a second vehicle width when at said another location, wherein the first vehicle width is less than the second vehicle width. A jack-up vessel such as this can maintain stability when elevated with square positioning of supporting legs and yet reposition the hull sections to achieve a preferred hull shape for transit from location-to-location at more than twice the usual speed of known jack-up vessels.
