A Trailing Suction Hopper Dredger is a vessel that is suited for deep-sea navigation with the ability to load
material into its own hopper by means of centrifugal pump(s) and suction pipe(s). Figure 1 shows a possible
layout of a TSHD.

Co

ns
en

Trailing Suction Hopper Dredgers belong to the type of non-stationary dredgers. This means that TSHD are
required to sail during dredging operations.

Figure 1 Typical TSHD layout
When the Trailing Suction Hopper Dredger approaches the dredging area, at the start of a new dredging cycle,

the TSHD will reduce its speed and will put the trailing suction pipes overboard.
During the approach the suction heads at the end of the trailing suction pipes will be kept a couple of metres
above the seabed until the indicated dredging area has been reached. Once close to the indicated dredging
area the dredge pumps will be started. The dredge pumps will start taking in seawater through the trailing

suction pipes. The seawater that will be taken in prior to the suction heads touching the soil, will be pumped

overboard again or in some cases remains in the hopper.
As soon as the suction heads touch the seabed and bottom material is sucked through the suction heads and
trailing pipes, the dredger operator will divert the soil mixture into the hopper by closing the pump overboard
valve, thus avoiding spillage of dredged material.
During dredging the TSHD will sail with a speed around 1 to 3 knots, depending on the dredge location,
surrounding marine activities, sea conditions and soil parameters. Due to the speed of the TSHD the suction
heads will loosen the bottom material. In this way a mixture of soil and water is created that than can be
sucked trough the suction heads, into the TSHD's own hopper. Water jets or teeth (or both), which may be
constructed in the suction heads, can assist in loosening the soil, hence optimising the production.

se

.

The material to be dredged will be stripped of the bottom in layers over the full width of the dredging area.

The position of the suction head and the trailing suction pipe can be monitored by checking the following
measurements:
- Measuring the pitch, heave and roll of the vessel in combination with the draught and trim of
the vessel;
- Measuring the angles of the different parts of the trailing suction pipes and suction heads
relative to a horizon with angle metres;
- Measuring the depths of the different parts of the trailing suction pipes by using pressure
readings from specially installed sensors.

Co

ns
en

As a backup system an open end thin tube from the start of the trailing suction pipe down to the suction head
is installed, through which air can be pumped under pressure. The air pressure at the exact moment bubbles
appear gives an indication for the dredging depth.
The measurements as mentioned above make that the TSHD is more or less able to determine how deep and
under what angle the suction head is used while dredging. These measurements will also give an indication to
the dredging operator in which way the profiles and depths already have been reached.
The production of a TSHD depends on many factors, among which: soil characteristics (in-situ density, particle

distribution, SPT and/or CPT values, etc...), dredging depth, weather conditions, sailing distances, marine traffic,
tides, currents, etc
A dredging cycle manly exists of the following 4 consecutive operations
Loading
Sailing Full
Unloading
Sailing empty

Average trailing speed 1 to 3 knots, depending on the soil type;
Average speed from 1 knot to maximum sailing speed, depending on wind, swell, current,
weather conditions, keel clearance and sailing distance;
Average speed from 0 knot to 3 knots sailing speed, depending on the soil type, wind,
swell, current, weather conditions and keel clearance;
Average speed from 1 knot to maximum sailing speed, depending on wind, swell, current,
weather conditions, keel clearance and sailing distance;

The different steps in the dredging cycle are further elaborated in paragraphs 4.2.1 to 4.2.4
The time to complete on full cycle depends on:

The dredging time required for filling up the hopper and the load per trip will vary depending on
soil parameters, dredging depths and other circumstances.;
The sailing time, both full and empty, depend on traffic speed limits, currents, tides, weather
conditions, sailing distances and route to the unloading area, etc...;
The unloading time depends mainly on soil characteristics.

TSHD operates 24/7.

The maximum volume of dredged material a TSHD can load in its hopper depends mainly on the size of the hopper
and the soil characteristics of the dredged material. The same volume of dredged material can differ in weight
depending on the dredge location, caused by different soil characteristics. Due to the limitations in volume and
weight a TSHD can carry, the maximum volume of dredged material that can be loaded depends on the volume
weight of the dredged material. The TSHD will start loading dredged material into its hopper until the maximum
volume or the maximum weight has been reached, whatever comes first.
To control the dredging position, the TSHD is equipped with a RTK-DGPS system. The TSHD is also
equipped with an automatic suction head control system to ensure a correct dredging depth.

During dredging generally, in soft materials the drag head sinks into the soil and with a slow forward movement a
high concentration of materials can be lifted. In firmer materials the penetration depth is less and a greater forward
speed is required to maintain a sufficient high concentration of material.

Co

ns
en

Since the dredge pumps feeds the hopper with a diluted soil / water mixture, the soil will settle in the hopper and the
excess water will be discharged via an overflow. Loading can be continued until the vessel's draught reaches the
load mark or until other circumstances do not allow for further loading. When dredging light materials, such as silt,
difficulties may arise in the settling of the dredged material in the hopper. Under these circumstances, the hopper
capacity is usually increased by raising the overflow.
When the hopper is fully loaded, the suction head is lifted from the bottom and the pumping system is turned
off. The suction pipes will be hoisted on deck and secured onboard.

4.2.2. Sailing Full
After loading, the TSHD leaves the dredging area and proceeds to the area where the load will be unloaded.
During sailing the hopper remains closed with all valves shut.

4.2.3. Unloading the TSHD through bottom doors / valves
On arrival, at the discharge location, the speed of the TSHD is reduced and the vessel is carefully positioned in the
middle of the disposal area. When the TSHD is positioned in the correct position the bottom valves are opened. All
material is now discharged from the hopper in a very controlled short period.
Unloading trough the bottom doors / valves of the TSHD can only be done if the water depth at the unloading
area surpasses a minimum depth. When the required minimum depth is not available or has been reached the
water depth will be too shallow for the TSHD to sail / unload its next load through the bottom doors / valves.

4.2.4. Sailing Empty
When the hopper of the TSHD has been emptied the TSHD will set course again to the dredging location. When
the dredger arrives at the dredging location, the entire dredging cycle can start over new.

This dredging campaign, due to the spread of the material, the TSHD will turn when the vessel is fully loaded.
This can be a problem in certain places where the width of the channel is limited. Therefore the dredging
sequence will be governed by tide and ship movements, e.g.: If the TSHD is going to be fully loaded half way
up the lock, inbound, then it will need sufficient water to turn around in the channel wherever the TSHD will be
at that moment. This will need to be on a flood tide. If there are shipping movements ongoing maybe the
TSHD will have to go all the way up to Tivoli to turn as there is insufficient room to pass in the channel. The
officer of watch will need to make the decision each time they return form the dumping area as to where the
vessel can commence dredging.

To be advised by client based on the in-survey to be done prior to the works.

Prior to start dredging Van Oord UK will meet with the Client to discuss points of concern, e.g. removal of
channel buoys to allow unrestricted access for the dredger.
4.4.2 Weather Conditions
The dredging operation can be carried out during fair weather. Limiting sea states for dredging and sand
supply works are defined as Hs (significant wave height) of approximately 1.50 metres and wind speeds of
approximately 6 Beaufort.
It should be noted that wave direction, wave period, wind direction, presence of currents and combinations of
these will influence the limiting sea states significantly.
The Master of the Vessel will determine when conditions are such that the works have to be suspended or can
be recommenced.
During periods of weather delay the TSHD can decide to go for anchorage. This anchorage can be outside the
work site and not necessarily be in a harbour. Weather forecasts will be available on a daily basis.

Assisting equipment for the TSHD

Van Oord Ireland Ltd is the operator of the dredging system known as Water Injection Dredging. The Water
Injection Dredging system is unique. The silt is in this case partially- re-liquefied by low-pressure injection of
water. The layer thus formed is a liquid denser than water, which flows under the forces of nature present in
the area, and for the works above, the gravitational force of the bed slope. Within the confines of the area, the
layer formed will flow principally under the gravitational force of the bed slope only. For the works above the
WID technique will be used for areas which are difficult to access by the TSHD, the WID will dredge the
material towards an area where the TSHD can collect this material.

se

.

5.1 Scope of Works:
To clear accumulated silts and fine sands in conjunction with the TSHD from the - by TSHD - difficult to reach
dredge areas and towline dredging by use of our Water Injection Dredger Jetsed to the required depths.
