TSHD Swalinge renovation
Familiar and good
The Swalinge was built as a coaster in 1977 and rebuilt into a trailing-suction hopper dredger after being purchased by Den Herder Seaworks in 1996.
The extension of the Swalinge with 37.1 m will be realized in the spring of 2022. This will increase the current hopper volume from 1800m³ to 3000m³.
The dry-unloading installation with unloading crane, conveyor belts and shore belt have been developed and built according to our own insight. The unloading time of the Swalinge will be 2.5 hours on average. The ship will be equipped with a specially designed hydraulically adjustable sieving installation.
With the help of spud poles, mooring operations are limited to a minimum.
Extension and modernization of the TSHD Swalinge
In order to be able to better serve customers in the future, the shareholders of Den Herder Seaworks BV have decided to extend and modernize the Swalinge.
This improves the deployment options within our fleet for the Swalinge and allows transport movements/deliveries to be better coordinated and optimised.
The hull of the Swalinge is still very suitable for an extension and the ship will retain its ice class after the renovation.
The main components of the conversion of the TSHD Swalinge are:
- extension by 37.1 m, increasing the loading capacity by 1200 m3 to approx. 3000 m3.
- Installing two extendable spud poles to shorten mooring and mooring times.
- The construction and design of a completely new hydraulically adjustable sieving installation.
- Fitting a second 450 kW bow thruster for better manoeuvrability.
- Fitting a nozzle around the propeller.
- Installing a newly designed bulbous bow.
The total conversion and supply of all necessary components is done in and by Dutch companies.
