Abstract

A BOP device is disclosed which has two pairs of opposed rams located in a single plane with the pairs of rams being disposed in the plane so that the pairs of rams move in directions orthogonal to each other. This means that the same number of rams can be deployed in a BOP device half the height. One BOP unit can have two sets of pipe rams, with the pipe rams being by having pipe ram heads sized to accommodate different diameters and a second BOP unit can have a set of pipe rams and a set of shear or blade rams for being actuated to seal off the BOP. Thus, four sets of rams can be disposed in a height approximately 50% of that formerly accommodated by four sets of rams thus minimising the weight of the BOP structure and significantly reducing the bending moment by around 50% on the wellhead. Embodiments of the invention are described.
