Marine aggregate dredgers operate
in licence areas in coastal waters and open seas where other shipping
is present. This introduces a risk of collision between the dredger
(which is generally stationary or travelling at low speeds when
dredging), and passing shipping.
Anatec personnel have gained
first-hand experience onboard a working marine aggregates dredger.
This experience has been applied when chairing and participating
in workshops to define operating procedures for dredging in busy
shipping areas, and to identify measures to reduce the risk of collision,
such as bridge manning and allowable visibility criteria.
Detailed risk assessment work
has been performed using computer modelling to estimate the risk
of collision between dredgers and passing merchant and fishing vessels,
taking into account:
• Historical risk level
• Ship collision causation factors
• Dredge licence areas
• Vessel specification
• Passing shipping (routeing, density and composition)
• Risk mitigation measures
Our experience includes assessing
the risks associated with proposed dredging operations in the English
Channel, one of the World’s busiest waterways, as well as
several other offshore areas in the UK.
