Pipe laying

Most of the projects have been executed in shallow waters by means of the submerged pipelay method. With the submerged method a string of pipe is kept afloat by means of buoyancy tanks and towed to the field. When positioned on the exact location in the field the pipe line is installed by ballasting the tanks one by one in controlled manner and sequence.

Besides projects in shallow water NCGS Group is also targeting pipelay projects in deeper water. For these types of projects NCGS Group is developing a pipelay barge which is suitable to install pipelines with the S-lay method.
