Abstract
Various aspects include devices, systems, and methods for securing an anchoring element to a seafloor. The methods may use a subsea anchorage installation system that may include a subsea grout supply assembly. The subsea grout supply assembly may include a variable volume grout storage chamber, a paddle, and a subsea grout pump. The variable volume grout storage chamber may be configured to transport dry grout to a seafloor. The variable volume grout storage chamber may include a water injection port configured to receive water for mixing with the dry grout on the seafloor. The variable volume grout storage chamber may also be configured to expand from a collapsed configuration as water is injected.
Claims21
A subsea anchorage installation system, comprising:
- a variable volume grout storage chamber configured to transport dry grout therein;
- a water injection port configured to enable water to be injected into the variable volume grout storage chamber for mixing with the dry grout to form a grout mixture after the variable volume grout storage chamber is under water, wherein the variable volume grout storage chamber is configured to expand from a collapsed configuration as water is injected through the water injection port;
- and
- a paddle disposed in the variable volume grout storage chamber, wherein the paddle is configured to mix the dry grout and water received through the water injection port into the grout mixture.
A subsea anchorage installation system, comprising:
- a variable volume grout storage chamber configured to transport dry grout therein;
- a water injection port configured to enable water to be injected into the variable volume grout storage chamber for mixing with the dry grout to form a grout mixture after the variable volume grout storage chamber is under water, wherein the variable volume grout storage chamber is configured to expand from a collapsed configuration as water is injected through the water injection port;
- and
- a subsea drill rig comprising:
- a drill mast configured to be raised to a select drill angle;
- a drill head coupled to the drill mast, wherein the drill head is configured to drill an anchoring element into the seafloor at a drill location;
- and
- a plume hood coupled to the drill head, wherein the plume hood is configured to collect sediment generated in association with drilling the anchoring element into the seafloor.
A method of installing anchoring elements in a seafloor, comprising:
- transporting dry grout to the seafloor in a variable volume grout storage chamber, wherein the transported dry grout is maintained dry at the seafloor within the variable volume grout storage chamber;
- and
- mixing the transported dry grout and water to form a grout mixture within the variable volume grout storage chamber at the seafloor.
