1 Scope This chapter provides a general project description and the scope of work covered under this method statement including the requirements.

1.1 Project description Maintenance dredging is required at Malahide Marina for safe navigation of vessels. An estimated 17,000m³ of silt is required to be removed using Water Injection Dredging. Dredging is required over an initial campaign in Nov-Jan 2018/2019. Two subsequent campaigns in Nov-Jan 2021/2022 and Nov-Jan 2024/2025 are required. Volumes of the 2nd and 3rd dredging campaign will be assessed prior to commencement of operations.

Van Oord is the leading contractor in the dredging technique called ‘Water Injection Dredging’ (WID). This hydrodynamic dredging technique uses the natural dynamics of the system where the horizontal transport takes place in the water column. The Tidal and river current, together with the gravitational effect, transport the dredge material out to sea. This sustainable dredging technique developed by Van Oord eliminates the need for traditional dredging techniques and is a lot more cost effective.

The variety and in general small size of these projects still require the Van Oord standard and comply with all Irish laws and regulations.

The Project Management Plan (including all supporting documents) is set up as one overall covering management document. It covers all the running, and future, stand-alone maintenance Water Injection Dredging projects in Ireland executed by Van Oord Ireland Ltd. The scope of works include maintenance dredging in rivers and canals and at locks, docks and jetty’s varying from large Ports and Harbours to small Marina’s.

1.2 Scope method statement This Method Statement is made for the WID activities in Malahide Marina and falls under the overall WID Ireland Project Management Plan. The various dredge locations are outlined below.

November / January • Campaign 2018/19 – total estimated 17,000m3 to be removed • Campaign 2021/22 – total estimated tbc m3 • Campaign 2024/25 – total estimated tbc m3

As agreed with the Harbour Master, various locations within the Harbour will be dredged using Water Injection Dredging. The WID Borr [or equivalent] will be mobilised for the works.

This Method Statement has developed and will be implemented with the health, safety and welfare of all personnel, the public, wild life and the environment being of utmost priority.

The content of this Method Statement is to be verbally communicated to the workforce involved by the Superintendent the day prior to the task commencement, this ensures that the correct personnel, tools and equipment are in place and gives enough time for suggestions or additional control measures identified during the briefing to be included within the Method Statement.

Where required the activities will be re-briefed in the form of a toolbox talk on the day of the activity, to ensure that the requirements are fully understood. Feedback from the workforce is encouraged.

1.3 Requirements For the requirements applicable to the scope of work covered under this method statement reference is made to the following documents:

3 Methodology This chapter describes the approach how the scope of works covered under this Method Statement will be realised and stipulates the preparation works, execution method and planning.

3.1 Preparation The dredger is to be mobilised via road to Malahide Marina in Malahide, Ireland.

On arrival the dredger will be assembled on the quay and lifted in the water in its entirety. The lifting operation will be carried out by a mobile crane. To lift the vessel a heavy crane will be required with the capacity to lift 62T. The lifting process will be planned and supervised by a Van Oord appointed person in close cooperation with the local Authorities. All lift plans, waivers and risk assessments will be put in place before the lift is undertaken. The reverse process will be carried out for the demobilisation of the crane at the end of the job.

3.2 Execution

3.2.1 Principles of Water Injection Dredging

Van Oord Ireland is the operator of the dredging system known as Water Injection Dredging. The Water Injection Dredging system is unique in its design to remove silty material from the seabed. A jet bar is moved over the surface of the seabed while the nozzles inject large volumes of water at low pressure into the sediment layer.

The density of the soil layer is lowered until it shows fluid behaviour. The fluidized sediment layer is then transported horizontally in the lower part of the water column away from the dredged areas. The hydrostatic pressure difference, the gradient of the seabed and the tidal and current flows are the main driving forces for this natural horizontal transport. In most cases the fluidized sediment will finally re-enter the water column in a high energy environment where it will be mixed with other naturally occurring sediment particles. From there on the sediment continues its natural route towards its original destination.

The WID process explained in 6 minutes: https://www.vimeo.com/69300630 [no login required]

3.2.2 Scope of works

Deposited fine silts within the various dredge locations will be dredged on the Broadmeadow River estuary. The dredged material will be transported using flow channels to the deeper area within the Harbour and dispersed over the ebbing tide out to sea. A total of 40 tides of dredging is anticipated, with the aim to remove 17,500m3 of silt.

The flow channels are indicated in red. The dredger will remove the material from in between the finger pier pontoons towards the flow channels. In yellow the movable marina pontoons are indicated. The marina pontoons can be moved to facilitate the ease of dredging and significantly reduce the dredging time required.

3.3 Planning Mobilisation on site will be on a date as agreed with the Client.

Based on the envisaged workload of dredging 40 tides we anticipate to have the works complete within 20 days. The total operation including mobilisation and demobilisation is expected to take approximately 24 days. Operations will be carried out on either tides (consisting of a 6 hour period on the ebb tide, including setup and mooring up).

Our site representative Farrell McCullough or Lizzie Chellew will have a daily meeting with the Port Engineer to discuss progress of the works and planning.

5 Quality This chapter describes all quality aspects directly related to the scope of work covered under this method statement.

For the overall project information on the quality aspects reference is made to the Project Quality Plan <20.0000-VO-VOM-PR-0009>.

A pre-survey will be provided by the Client. This data is used to plan the dredging operations as described in previous sections. The survey data will also be available onboard the dredger, where it is updated with the position and depth of the bar, so that the dredger can keep track of where it has worked.

All dredgers use a contracted online system to receive RTK – Water level information and correction.

Every day a screen dump is made of the dredging tracks to provide both the Client and the project team a visual overview of the works carried out each day. The screen dumps are supported by daily reporting. An example screen dump is shown below.

Upon completion a post dredge hydrographic survey will be organised by Hydrographic Surveys Ltd (by the Client).

As part of this Method Statement an Inspection and Test Plan (ITP) has been prepared in line with the Project Quality Plan. Further reference is made to the ITP (VOMS-2.04-TE-03-09-03) in the appendices.
