D. Loading Operations

D.1 Purpose of the Operation

The Port of Waterford Company was originally known as Waterford Harbour Commissioners and was established in 1816. In 1999, the organisation was incorporated as the Port of Waterford Company, and now operates in the commercial semi-state sector in Ireland, reporting to the Department of Transport. Since its foundation, the organisation has played a vital role in the development of the city and the region.

In the 1990's, commercial shipping operations moved to Belview, some 5 miles downstream of Waterford City, and closer to the sea. The Port now offer facilities for bulk and breakbulk, liquid bulk and container cargoes and is the closest Irish multi-modal port to continental Europe.

The River Suir catchment, which comprises dry mineral soils, is subjected to varying degrees of runoff and soil erosion. In the lower reaches of the river there are vast quantities of sediment being eroded, held in suspension and deposited through the ebb and flood tides in the estuary. Thus when a channel is deepened by dredging there is an immediate and natural response as sedimentation takes place to restore equilibrium. These high spots, river and tidal deposits bring the bed levels of the navigation channel and berths above the advertised depths, which gives rise to repeated requirement for dredging in order to maintain the required minimum depths.

The navigation channel into Waterford Port has for the most part good water depths but there are sand bars at Duncannon and Cheekpoint that restrict navigation into the Port. These, in conjunction with the berths at Belview, are the primary dredging areas and require dredging at least twice a year Reference Attachment D.1). Maintenance of the navigation channel through these bars is essential to maintain and improve the competitiveness and efficiency of the Port.

A disposal at sea permit is required to allow for the regular disposal of the maintenance dredged material from the navigation access channels and berths within the Port’s harbour limits. Maintenance dredging ensures the safe navigation of trade, commercial and recreational vessels in the area.

D.3 Details of Operation

D.3.1 Dredging Requirements

This permit application requests that date of commencement be the 1 st January 2014 and run for a period of 8 years until the 31 st December 2021. It is requested that the maintenance dredging required be allowed to be undertaken at any time during this period as identified by hydrographic survey.

The total volumes of material to be dredged, and the anticipated schedule, are outlined in Section D.3.3.

The maximum volume of material disposed of per day at the designated disposal site has been variable over the past 20 years, with the figure selected dependant on the size of the dredger being utilised. We would request that the daily volume of material be set at the previously specified limit of 35,000 tonnes. No negative environmental impacts were noted during the period when this limit was in place. This would allow the Port to avail of larger dredgers within the Irish and UK marketplace and therefore achieve the best value for money though economies of scale. Please refer to Attachment D.3(i) for previous correspondence on this matter.

The current dumping at sea permit does not allow dredging between the start of March and the end of June, with the exception of Duncannon Bar which was excluded after a consultation process in 2011. This seasonal restriction has been referred to as the ‘closed period’ . However, based on reports and monitoring undertaken, at the request of the EPA, we would request, based on the evidence collected (Attachment F.1(viii)) that all areas downstream of Cheekpoint Upper are also excluded from this restriction.

Dear Mr. Grant,

Following our conversation earlier today, on behalf of the Port of Waterford we would like to formally apply for an alteration to the Port of Waterford’s Loading and Dumping Permit No. 396. The alteration we seek is to the daily disposal limit, which is current given as 20,000 tonnes.

There is significant variation in the daily disposal limit in recent years. Table 1 below outlines the varying daily disposal limits between 1999 to 2010.

Year Dredger Name Daily Disposal Limit (tonnes) 1999 Lesse/Amazone 25,000 2000 Lesse 25,000 2001 Lesse 21,000 2002 Lesse/Seine 21,000/12,000 2003 Seine 12,000 2004 Seine/Amazone 21,000 2005 Bluefin 35,000 2006 Bluefin 35,000 2007 Bluefin 35,000 2008 Bluefin/Dolphin 35,000/20,000 2009 Bluefin/Dolphin 20,000 2010 Bluefin/Dolphin/Orca 20,000 Table 1 The Port of Waterford’s Daily Disposal Limits between 1999 to 2010

We understand that your department were not responsible for Loading and Dumping permits during most of the above time period and might not therefore have access to the logic behind the varying quantities stated on the historical permits presented above. We, as the port’s dredging consultants for the past 16 years, are of the opinion that the daily disposal limit has always been governed by the dredger named on the licence and its associated anticipated production rates.

The present limit of 20,000t/day has not been an issue recently due to the chosen approach of the last dredging contractor. However, due to the present ongoing difficult financial climate the type of contract adopted has had to be changed to a time charter basis. As you will no doubt be aware the cost of dredging plant is very high and as such it in vital that it is used efficiently. When work is stopped for any reason, that is not the contractors responsibility, they continue to receive payment for the plant. This will be the case with the current daily disposal limit as it is likely to impede the dredger from achieving its optimum productivity. Depending on the dredger selected, this could lead to up to 67% of each day’s productivity being lost, which will result in significantly higher dredging costs to the Port. In sites where full productivity can be achieved this can lead to considerable savings.

In conclusion, we would respectfully request reconsideration of the daily disposal limit condition stipulated to the Port of Waterford’s Loading & Dumping Permit being increased to 30,000 tonnes daily. This is the maximum quantity we have estimated that could be deposited in any one day. Please note that this does not represent a daily disposal of 30,000t, the average disposal is expected to be lower than this. However, when dredging at the South end of the Duncannon channel, where transit distances to the disposal site are short, the productivity of the dredger may reach 30,000t on occasions

If you have any questions or require any additional information, do not hesitate to call or e- mail ([email protected]) and we will try to resolve them.

Yours sincerely,

Colm Sheehan Anthony D Bates Partnership LLP

D.3.2 Dredging Methodology

Due to the specific logistics of the Port of Waterford a Trailing Suction Hopper Dredger (TSHD) is the primary dredging method used to maintain the design depth of the navigational channels (6.5mBCD) and the outer accessible areas of the Port’s berths. The areas to be dredged will be identified regularly by hydrographic survey. To start the dredging operations, the TSHD will sail to the area to be dredged. Once in the vicinity of its dredging area, the TSHD will lower the draghead(s) to the bottom and dredging can commence. The centrifugal dredge pump, installed inside the dredger, takes up a mixture of water and soil through the draghead and suction pipe and pumps the mixture into its hopper. The soil will settle in the hopper and the water is discharged through an adjustable overflow system. When the draught of the vessel reaches the dredging loading mark or when circumstances do not allow for further loading, dredging will be ceased and the suction pipe hoisted on deck. The dredger will fill its hopper in each of the identified dredging areas as efficiently as possible.

Upon filling its hold the dredger will sail to the licensed disposal site and slows to approximately one to two knots. The dredger will then open bottom doors or split along its hull to allow the release of its contents over several minutes. During the disposal operation the dredger is travelling at between one to two knots within the disposal area. Due to this the material is placed over a substantial portion of the disposal site and ensures against accumulation of material within an isolated area (e.g. the centre of the disposal site). This process is repeated for each disposal operation with the master of the vessel referring to the previous disposal areas used within the on-board tracking system and selecting a new disposal area (within the licensed area) not previously used in that campaign. By using as much of the disposal site as possible any impacts from the disposal activity are minimised.

This process is continued until interim hydrographic surveys show that the required safe navigation depths required have been achieved and dredging can cease.

In conjunction with the TSHD a plough dredger may also be used. Ploughing is a method of moving bottom sediments over short distances to level an irregular bed (normally left by a TSHD); to move sediment from a location where it causes a restriction or obstruction; or to move sediment from an area that is inaccessible (such as a quay wall) to other larger dredging plant to a location where it can be accessed safely, dredged and removed. Sediment movement is achieved by towing a bottomless rectangular box shaped fabricated steel implement behind a powered vessel, usually a small workboat or tug. If used correctly, the plough is suspended at a controlled height from an A-frame mounted over the stern of the towing vessel. Height, or depth of submergence, is controlled by a deck mounted hoist winch. The cutting blade at the leading edge of the plough slices the surface sediment which is then contained within the sides and rear of the following plough until reaching an area where the bed level is lower than the suspended level of the plough, whereupon the contained sediment falls from the open bottom of the plough. The plough is then raised above the general seabed level and the towing vessel returns to the area from which sediment is to be moved and repeats the cycle. This method is commonly used in conjunction with a TSHD.

There is also the potential for utilisation of a mechanical dredger. As stated above the plough dredger is used in areas that the TSHD cannot access. However, in some instances the inaccessible material cannot be displaced by the plough dredger and an alternative item of plant is required. This is normally

a mechanical dredger such as a grab or backhoe dredger. These dredgers use a bucket lowered to the seabed to excavate the targeted sediment material which is then raised to the surface. However, these dredgers do not have any means of transporting the dredged sediment so ‘hopper barges’ are required to be filled and transit to the licensed disposal site. The areas that may require the use of a mechanical dredger are limited to quay walls and berths where material has been compressed and has consolidated to a degree that it cannot be removed by the use of a plough dredger. This option is not favoured by the Port as it is significantly more expensive that the use of a TSHD/plough and it is only utilised as a last resort when conditions dictate the standard processes are technically unfeasible.

D.3.3 Dredging Volumes and Anticipated Schedule

The dredging programme of the Port of Waterford for the requested 8 year permit is set out below in the following table. Dredging will be carried out on an as required basis, with a degree of over dredging to provide sedimentation capacity and maintain minimum depths.

The areas and predicted quantities of material to be dredged are tabulated. The dredge volumes include for an overdredge of approximately 0.5 metres to ensure that the advertised depth of the channel will be achieved. These quantities also take account of slopes to the sides of the channel. The total volume requested over the 8 year permit to the end of 2021 proposes to dispose of less material annually than the previous permit.

Quantities can vary considerably depending on the severity of weather conditions, river flow and prevailing wind direction but the experience gained during the recent maintenance contracts at Duncannon and Cheekpoint has helped in predicting the quantities for the next eight years.

The contingency quantity is provided in order to allow for unpredictable future changes in weather patterns, which may cause a significant increased dredging requirement. Severe sedimentation has occurred in the past after a storm event and this contingency is included to ensure that the port can act immediately to reduce the build-up and allow trade to continue.
