Sediments

Marine sediments in the estuary:

Sands: 2.5 million m³ immersed into the sea

Inner part of the river:

Sandy materials: 3.5 million m³

Silty materials: 1.5 million m³

Sand and gravels manufacture building material

Finer sand backfill

Clay filling water bodies of old quarries

2.3 Public communication

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

The objectives of the public consultation are:

1) Allow everyone to learn and understand issues and characteristics of the project

2) Promote the expression of opinions and viewpoints

3) Understand the concerns and expectations of the participants

4) Draw useful lessons of the project

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

3. THE ROLE OF THE HARBOURMASTER IN THE DESIGN AND THE PROCESS

Before the project: statement of the problem

During the studies: consulting and project evaluation

During the realization of the project: support

After te realization of the project: adaptation to the new configuration of the fairway

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

3.1 Statement of the problem

The harbourmaster is in the forefront managing the problems due to insufficient available draught:

- concentration of traffic in a small time window

- availabilty of tugs

- risks for navigation safety: crossings, poor ukc…

- claims of ships’ captains

Consequencies:

- Lay-by berths, waiting times, delays, extracharges…

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

3.2 Consulting and project evaluation

Interface between terminal operators and port management

Nautical advisor

Facilitator in the conduct of the project

Believable voice during the public communication

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

3.3 Support during the project realization

Harbourmaster manages navigation safety on the river:

- presence of dredgers in the fairway

- explosions

- soundings on a regular basis

- communication about dredging works to established continuously on the river

The VTS has a key role in the dredging in progress

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

3.4 Adaptation to the new configuration of the fairway Time windows for entering and leaving the port will

change

New procedures for traffic regulation are required

Accurate soundings follow up must be done for keeping the new draughts

Safety berths must be available along the river for vessels with new maximum draught

A reflexion must already be done for the adaptation of the port to the vessels of the future

8th IHMA Congress - 14/18 may 2012 - Cork, Ireland

4. CONCLUSION

The dredging project will give to the port of Rouen the oppportunity to perpetuate its development

It will permit to:

- reduce maritime transport costs

- reduce logistic chain costs

- increase number of employments in the port area

- reduce the environmental impact of transport

In this challenge the role of the harbourmaster is essential, from the beginning to the end of the project.
