[0043] Step 3: Lower the steel pipe pile into the water.

[0044] Step 4: Lower the steel pipe pile into the seabed guide device, which can be processed according to the actual construction needs.

[0045] Step 5: Release the connection between the lowering device and the steel pipe pile.

[0046] Step 6: Use hydraulic hammer to pile underwater.

[0047] Step 7: Pile to a certain depth, use ROV underwater robot to release the guide device, and pile the steel pipe pile to the designed height.

[0048] Step 8: Use ROV underwater robot to pull and hoist the seabed guide device.

[0049] 3. Seabed precast base positioning and container module installation, main construction steps: ​
