Pipe Laying Barge Market: Barges used for shallow water pipeline construction. 

The term "pipe-laying barge" often refers to vessels used for laying pipelines, but it can also specifically describe non-self-propelled vessels that require tugs to move. They are often used in shallower waters where a fixed anchor spread is sufficient for positioning. The pipe-laying barge market is an essential part of the industry, particularly for projects closer to shore.

Types: There are S-lay barges and J-lay barges, each designed for specific installation methods and water depths.

Cost-Effectiveness: Barges can be a more cost-effective option for certain projects compared to expensive, self-propelled pipe-laying vessels, especially when working in less complex environments.
