A trailing suction hopper dredger[1] (TSHD) is a type of ship capable of maintaining navigable waterways, deepening the maritime canals that are threatened to become silted, constructing new land elsewhere or replacing sand eroded by storms or wave action on the beaches.

Boskalis deploys trailing suction hoppers dredgers for the construction and maintenance of ports and waterways as well as land reclamation and coastal defense and riverbank protection. Trailing suction hopper dredgers are equipped with one or two suction pipes ending in drag heads.

Learn how a trailing suction hopper dredger works. The name trailing suction hopper dredger (TSHD) refers to the fact that this type of vessel dredges while slowly sailing, trailing one or two suction arms off the side of the hull. At the entrance of …

Using extensive in-house and in-depth dredging expertise, our engineers have designed Trailing Suction Hopper Dredgers (TSHD) from the user’s perspective; from 1,000 m³ to 5,000 m³. Efficient in operation and practical in maintenance, they are the most advanced and sustainable TSHDs we have ever built.

We design and build a variety of standardised and custom-built trailing suction hopper dredgers (TSHDs). A hopper dredger is a versatile dredger that unite dredging, transport and discharge in a single piece of equipment. Our TSHDs are ideal for many dredging jobs, such as land reclamation, port maintenance and aggregates dredging.

A trailing suction hopper dredger dredges loose material and soft soils such as sand, gravel, sludge or clay. One or two suction pipes are lowered on the seabed and the drag head is trailed over the bottom. A pump system sucks up a mixture of soil and water and discharges it in the ‘hopper’ or hold of the ship.

A Trailing Suction Hopper Dredger (TSHD) is a sea-going self-propelled free floating vessel that loads dredged material into its hopper well. The TSHD’s dredging process consists of a cycle of a loading (dredging), transporting (sailing) and discharging.

2024年1月5日 · Invested and built by China Communications Construction Company Limited (CCCC), the TSHD is also China's first of its kind to be equipped with a dual-fuel power system, which means the dredger can be powered by both liquefied natural gas and diesel.

2022年6月5日 · Trailing suction hopper dredger (TSHD) is one of the two most mainstream ship types in the dredging industry today, and is widely used in dredging and remediation, channel excavation and maintenance, submarine tunnels and other projects. During the operation, the main working tools of the TSHD are the drag head and the drag arm.
