Dredging Delivers Denmarks New Container Terminal
Dredging contractor Rohde Nielsen A/S has moved more than 7m m3 of sand in helping to construct new container terminals at Aarhus Harbour in Denmark. The projects origins date to 1998 when a 25 year plan for the development of what is Denmarks largest and busiest port was published. Work in the harbour area was to concentrate on the container port. Phase 1 of the project was completed by 2001, with Rohde Nielsen A/S playing a significant role in shifting 5.5m m3 of sand.
When Phase 2 started last year
,
Rohde Nielsen’s dredgers
Kronborg R
,
Freja R
and
Sif R started work on the new Container Terminal East
,
which would lift the Baltic Sea hub into the ranks of the world’s top 100 container ports. S
and
was pumped from another part of Aarhus Bay
,
where Danish authorities had given permission for winning.
Despite the proximity to the new area thesse areas were not the easiest or most accessible
,
with the s
and
won from some 20m below sea level.
Each round trip from the winning area to the unloading area
and
back took each dredger five hours. Working on a 24/7 basis
,
each vessel made almost five complete voyages per day
,
moving a total of some 6.4m m3 of s
and
. Rohde Nielsen kept within what were perhaps the strictest environmental regulations anywhere in the world.
More than 3.5m m3 was required to create l
and
on which two new container terminals were to be built. Between these two terminals a new artificial basin gradually appeared
,
which was economically filled to a depth of 4
,
5m by the split hopper dredger Sif R
,
operating whilst there was still access to the basin from the rest of the harbour.
Danish contractors MT Højgaard started work on a new pier
,
with Rohde Nielen as subcontractor. After MJ Højgaard had placed the sheet piling
,
dredgers began rainbowing s
and
behind the artificial barrier to create the basis for a new quayside area which was later covered with concrete. Some 900
,
000 m3 of s
and
was delivered or this component of the project.
Rohde Nielsen also undertook environmental works on the south east side of the container terminal
,
filling an area that had been used as a dumping ground or harbour waste material for many years.
