London digs deep
The largest single dredging project to be
undertaken in the UK is shortly to com-
mence with the deepening of the access
channel to DP World’s new London Gate-
way container terminal, previously the site
of a Shell refinery. Shell was able to ac-
cept fully loaded tankers up to 120,000
dwt with a depth alongside the main T-
head jetty of 14.5m. However, the ap-
proach is tide-dependant and tankers
steamed in cautiously on a flood tide of-
ten with as little as 0.5m keel clearance.
This is not practical for container ships.
They require 24h access and departure
and, unlike oil tankers, do not arrive fully
loaded and depart empty.
The northern access channel will be
dredged to a depth of -14.5m below chart
datum and to a width of 300m, requiring
the removal of 2-3m depth of spoil to
