Abstract: Disclosed herein is a fuel oil composition comprising a renewable fuel or a blend of petroleum based fuels with renewable fuels, also containing an additives composition to enhance the base and combined fuel's resistance to forming insoluble particulates upon storage at diminished operating temperatures. Further described is the additive package used to inhibit particulate formation.

Abstract: A method is disclosed of controlling a ground engineering apparatus including an elongate member for creating a bore at a predetermined position and orientation. The method includes receiving a plurality of positional information signals relating to the apparatus, processing the positional information signals to generate positional data including a representation of the position and orientation of the elongate member relative to the predetermined position and orientation of the bore; and outputting a control signal for aligning the elongate member with the predetermined position and orientation of the bore. A ground engineering apparatus, computer apparatus, drilling rig and piling rig are also disclosed.
