Understanding the world of sand and water
This book is derived from chapter 2.2 + 9 of the main book: "Dredging Technology Book 1". It is a compact reference to the Trailing Suction Hopper Dredger (TSHD) for Civil Project Engineers involved in Dredging Projects. A broad description of the vessel is given and a lot of practical guidelines for the optimal use of the TSHD.
It is the 2nd sailing workhorse of the Dredging Industry, just beyond the CSD, having multiple discharge modes among them the unique self emptying capacity that enables the nowadays very large reclamation projects. Dragheads and suction tube and pump installation are being discussed.
Working methods and loading and unloading systems are being discussed and also the limitations and international loading rules are described.
