Trenching with a TSHD is not new, but when using a standard draghead, this is not efficient:
 

• the width of the head is a multiple of the product that will go in the trench
   

• ​the track keeping of the head is reduced

​

​

​

This means that a trench is much wider than the product that has to be laid in the trench. This results in:
 

• long execution times i.e. high cost
   

• ​important disturbance of the bottom
   

• large backfilling volumes​

​

​

Therefore, the design of a trenching head can reduce the execution cost and environmental impact drastically
