Pipe Laying including use of Submersibles
Definition:
Pipe laying is the process of installing pipelines on the seabed or underground. Submersibles are vehicles that can operate underwater. They are used in a variety of tasks, including pipe laying.
Types of submersibles used in pipe laying
There are two main types of submersibles used in pipe laying:
Remotely operated vehicles (ROVs):
ROVs are unmanned submersibles that are controlled from a surface vessel. They are typically used for tasks such as inspection, maintenance, and repair.
Manned submersibles:
Manned submersibles have a crew that operates the vehicle from inside. They are typically used for tasks that require human intervention, such as pipe laying and welding.
How submersibles are used in pipe laying?
Submersibles are used in a variety of ways in pipe laying operations. Some of the most common tasks include:
-
Inspection: Submersibles can be used to inspect the seabed before pipe laying begins to identify any potential hazards.
-
Preparation: Submersibles can be used to prepare the seabed for pipe laying by clearing away obstacles and leveling the surface.
-
Pipe laying: Submersibles can be used to lay pipe on the seabed. This is typically done by using a manipulator arm to attach the pipe to the seabed and then moving the submersible forward.
-
Welding: Submersibles can be used to weld the joints between pipe sections.
-
Inspection and repair: Submersibles can be used to inspect and repair pipelines after they have been laid.
Advantages of using submersibles in pipe laying
There are a number of advantages to using submersibles in pipe laying operations, including:
- Accuracy: Submersibles can be used to lay pipe very accurately, even in deep water and challenging conditions.
- Flexibility: Submersibles can be used to lay pipe in a variety of environments, including on the seabed, in rivers and lakes, and in underground tunnels.
- Safety: Submersibles can provide a safe way to lay pipe in dangerous environments, such as in areas with strong currents or underwater hazards.
Conclusion
Submersibles are a valuable tool for pipe laying operations. They can be used to perform a variety of tasks, including inspection, preparation, pipe laying, welding, and inspection and repair. Submersibles offer a number of advantages over other pipe laying methods, including accuracy, flexibility, and safety.
