“Required<br />
some careful<br />
maneuvering”<br />
Creating Connection<br />
Teamwork<br />
<strong>Mammoet</strong> Deutschland was commissioned<br />
to install a pipe bridge across the harbor<br />
entrance at HKM in Duisburg. The bridge<br />
weighed 290 tons and had a length of 120<br />
meters and a height and width of 5.5<br />
meters.<br />
The bridge was assembled on the quay<br />
and then lifted up by BTS sheerleg the<br />
“Amsterdam” and cranebarge the “Ibis”,<br />
turned around and placed on its supports.<br />
This was quite a challenge as the clearance<br />
to existing plant on site was quite small<br />
and as BTS’ equipment had little space to<br />
work in. However, the preparations paid<br />
off and the work went exactly as planned.<br />

JOB: INSTALLING A PIPE BRIDGE<br />
CHALLENGE: RESTRICTED SPACE<br />
BTS installed a new bridge across the<br />
lock at Terneuzen. This lock connects<br />
the inland waterways to the sea. At the<br />
building yard the bridge (approx. 61 by<br />
18 meters, 472 tons) was loaded onto the<br />
BTS “Krammer” barge by two sheerlegs.<br />
The bridge was then transported to<br />
Terneuzen where it was installed by<br />
the “Amsterdam” and “Ajax” sheerlegs.<br />
The installation required some careful<br />
manoeuvering by the crew as the lock<br />
chamber was quite narrow and provided<br />
little width for the sheerlegs to operate in.<br />
Impressive Lock Doors<br />
BTS was commissioned to replace two vertically moving doors and two ship<br />
impact resisting structures of the Bernhardsluis navigation lock at Tiel. The<br />
scope included transporting the components from the fabricator’s yard to the<br />
site and installing them. The 235 ton lock doors were quite impressive, with a<br />
length of 25 meters, a height of 17 meters and a thickness of 3 meters.<br />
The impact structures had the same dimensions and weighed 150 tons each.<br />
Installing the outer lock door was a fairly straightforward job for the BTS<br />
sheerlegs “Amsterdam” as there was enough space to operate in. However,<br />
to install the inner door the “Amsterdam’ had to work from within the lock<br />
chamber as there were road and rail bridges on the other side of the lock.<br />
BTS completed all the work according to schedule and the customer was very<br />
satisfied.<br />
