Abstract (en)

[origin: WO2017058005A1] A method and waste disposal system is provided for disposing a waste into a drilled borehole in a subtending tectonic plate. Herewith, waste can be disposed in a safe manner. The waste is transported from sea-level to the seabed by a carrier and introduced into a drilled borehole by using a docking station. The docking station allows a riser to remain connected to a wellhead during the introduction of the waste. Advantageously, the riser can be used as a guidance for the carrier. Additionally, the riser can be used after introducing the waste e.g. to seal the borehole or to introduce a dart to push waste further into the borehole. A further advantage is that the borehole is drilled along a curved path including a substantially horizontal section which contributes to an increased length of the borehole which advantageously allows an increase in storage of waste.
