Corrib Broadhaven Bay Nearshore Pipeline Route – 1-Month Post Construction Survey 2009

RSK Environment Ltd 1 RSK/He/P40036/40/03 rev01

1 Background The Corrib gas field lies in around 350m of water approximately 65km off the coast of County Mayo. Gas from the field is to be brought ashore via a 20-inch subsea pipeline, which makes its landfall at Dooncarton in Broadhaven Bay. From there, the pipeline will be routed onshore to the terminal at Bellanaboy Bridge.

Installation of the export gas pipeline and its landfall were consented under the Foreshore Act. Several conditions were attached to that consent, including surveys of the sediments in Broadhaven Bay, which may be affected by the installation of the pipeline. The first of this series of surveys was a “pre-construction” survey, which was intended to provide baseline conditions prior to the commencement of construction work. Following construction, three monitoring surveys will be undertaken, at 1-month (the present survey) and 6-months post completion of construction, and a further survey at the same time of year as the pre-construction survey (12 months after the pre-construction survey).

Pipeline installation was originally proposed for summer 2002, and a pre-construction survey of near-shore sediments along the proposed pipeline route was undertaken at that time. Thirty-six locations along the pipeline route through Broadhaven Bay were surveyed, with two additional reference stations being located to the north of the pipeline route (one off the coast from Rinnaglana, and one near Benwee Head) at the periphery of Broadhaven Bay. However, construction of the pipeline was delayed for a considerable period after this survey was completed, and it could therefore not be considered a “pre-construction” survey for the revised construction schedule.

RSK Environment Ltd (RSK) has been contracted by Shell E&P Ireland Ltd (SEPIL) to undertake the nearshore environmental monitoring programme (which includes the present 1-month post-construction survey). Following various delays, SEPIL planned to install the pipeline from the landfall out to the Corrib field in summer 2008, and consequently another “pre-construction” survey was undertaken in May 2008.

The installation works for the offshore pipeline were commenced and then suspended during summer 2008, and then successfully installed during summer 2009, with rock armouring of a nearshore section of the pipeline in Broadhaven Bay being completed in October 2009.

This benthic survey report details the first post-construction monitoring survey undertaken in November 2009, approximately 1-month following the completion of offshore construction activities.

It should be noted that future monitoring surveys are scheduled as per the Foreshore Licence conditions. Table 1.1 summarises the nearshore surveys that have been undertaken, and those that are scheduled to take place as part of the pre and post-construction monitoring of the offshore pipeline in Broadhaven Bay.

Corrib Broadhaven Bay Nearshore Pipeline Route – 1-Month Post Construction Survey 2009

RSK Environment Ltd 3 RSK/He/P40036/40/03 rev01

2 Objectives and Rationale The objectives of the 1-month post-construction survey are to monitor the physical and biological characteristics of the seabed of Broadhaven Bay immediately following the installation of the Corrib export pipeline, and to compare the results obtained with the results from post-construction surveys.

Aspects to be sampled, and the rationale for their selection, are as per the pre-construction survey (RSK, 2009) with the exception that samples were not collected for sediment infaunal analysis. The following briefly describes the parameters measured during the 1-month post-construction survey:

• Physico-chemical: Samples to be collected by Day grab, and parameters measured:

o Particle size analysis (PSA); and

o Total Organic Carbon (TOC). • Biological:

o Epibiota (i.e. those organisms living on the seabed surface) sampled using drop-down stills and video photography to provide qualitative, broad-scale data on the presence of larger organisms (e.g. echinoderms, fish) as well as general ecological conditions (e.g. macroalgae, sediment bedforms, presence of bedrock).

The data collected from this and future post-construction monitoring surveys will be compared with the results obtained from the baseline surveys of 2002 (EcoServe, 2002) and 2008 (RSK, 2009) to determine if effects from the installation of the pipeline through Broadhaven Bay are apparent, and if they are, to what distance from the pipeline they extend.

As per the 2008 pre-construction baseline survey, two reference stations were selected that are geographically removed from the pipeline route through Broadhaven Bay, but are likely to be subjected to similar natural environmental influences, as are those sites close to the pipeline route. Any natural changes seen at the stations over the whole survey period will need to be considered in the overall review of whether project-specific impacts are discernible.

This 1-month post-construction survey followed the same work-scope as the previous surveys, albeit with minor revisions, which are detailed in sections 2.1 and 4.1.

2.1 Planned sampling regime Data from grab and photographic sampling were to be collected from six transects crossing the nearshore pipeline route, each with 6 stations. These were selected so that data collected could be directly compared to the results of the May 2008, and 2002 pre-construction surveys undertaken by RSK and EcoServe respectively (EcoServe, 2002; RSK, 2009).

Stations were located at a distance of 25, 50 and 500m away from the pipeline on both sides. These distances differ from the pre-construction surveys, as concerns were raised regarding the proximity of seabed sampling equipment to the pipeline (which throughout much of Broadhaven Bay lies in an un-backfilled trench). As a result, stations 3 and 4 on each transect, originally at 10m distance from the pipeline were set back to 25m distance from the as-laid pipeline centre line.

3 Survey methods

3.1 Vessel As per the 2008 pre-construction survey, the survey vessel used was the Nomad (Figure 3.1) operated by Sinbad Marine Services. RSK provided navigational and survey personnel to undertake the work and all associated equipment. Positions were recorded as both UTM Grid and standard latitude and longitude positions (latitude and longitude in degrees, minutes and seconds, all in WGS84 datum). The target accuracy for positioning at benthic sample stations was within 10m of the proposed position. The specifications of the navigational equipment and the report of the navigation calibration check are presented in Appendix 1.

Figure 3.1: M/V Nomad

3.2 Dates Mobilisation of the Nomad in Killybegs harbour commenced on the 9th November 2009 with the vessel arriving in Ballyglass that same evening. The first survey operations were performed on the 10th November 2009 and the survey was completed on the 13th November 2009. All survey work was undertaken in daylight. Table 3.1 details the survey operations undertaken by date.

3.3 Grab sampling

A Day grab was used for sediment sample collection. Single samples were taken at each station.

Position, date, time, water depth, sediment type and other details (colour, smell, vertical layering, redox discontinuity layer, visible biota, evidence of biological activity) were recorded upon retrieval of the grab; a digital photograph was also taken of the sample, including a sample identification card. Between each deployment, the grab sampler was rinsed thoroughly and scrubbed clean to limit cross-contamination between sampling locations.

3.4 Drop-down photography Seabed photography was acquired using a digital video/stills camera with a lamp and strobe (Figure 3.2). The camera system was deployed within a specially designed stainless-steel frame allowing the equipment to be used at individual drop-down locations or to be towed in a sledge-type configuration. The camera system differed slightly from the 2008 pre-construction survey, where a Simrad-Kongsberg OE14-208 system was used.

Figure 3.2: Underwater camera equipment (BSL 3.4 megapixel system)

The seabed video footage was displayed live on a monitor onboard the Nomad and recorded directly onto DVD. A navigation data string displaying position, date and time was overlaid directly on to the recorded footage. At each photographic location a number of high-definition still photographs were taken and their positions recorded, a log sheet was completed that included position, transect and station, time, date, and water depth.

The camera system could be deployed in a straight up and down “drop-down” capacity in the event that sea conditions meant that towing the sledge along the seabed was not possible. In addition, there was the option to fit a freshwater lens to allow photography under conditions of poor visibility at the seabed. Full specifications of the camera system are included in Appendix 2.

3.5 Sample processing

3.5.1 Physico-chemical The single grab sample collected at each station was sub-sampled for both particle size analysis and TOC from the surface 5cm depth of sediment using a disposable plastic spoon. The samples were double-bagged with a waterproof internal identification label between the two bags, sealed and refrigerated before transfer under pre-established chain-of-custody procedures. Analysis was undertaken using accredited methods (UKAS (United Kingdom Accreditation Service)) by Benthic Solutions Ltd. Descriptive sediment classifications based on proportions of gravel (>2mm), sand (2mm-63µm) and mud (<63µm) were determined based on the Udden-Wentworth grain size classification scheme (Wentworth, 1922) methodology (Figure 3.3).

4 Results

4.1 Samples obtained In general, grab sampling was completed successfully. However, in some locations, the nature of the seabed was such that the Day grab was unable to retrieve a sample. In summary, all grab samples were obtained successfully from their planned location, with the exception of the following:

• No grab samples at 2 stations (B6 and C6) despite repeated grab deployments and subsequent slight relocation of sampling location. It was anticipated that no samples would be obtainable at these locations, from earlier appraisal of the drop-down photography, from the vessels echo-sounder during the sampling, and as a result of a similar failure to obtain samples at the locations during the 2008 pre-construction survey (RSK, 2009). The unsuccessful sampling at these locations is as a result of the presence of harder substrate (bedrock and cobbles), evidence of which is shown in the seabed images captured at these stations by the seabed photography (Figure 4.1);

• No samples from original location at 1 station (reference 2), despite a

number of grab deployments, and despite the fact that successful sampling was achieved at the location during 2008 (RSK, 2008). Successful sampling was achieved from a slightly revised location approximately 500m to the west of the target location, at a point when the vessels echosounder indicated that the seabed was no longer rocky in nature.

(shown on the left) and C6 (shown on the right)

Actual sampling locations are presented in Figure 4.2 and positions of sampled locations, distance from planned target, water depth, time and date are presented in the fix logs (Appendix 3).

Due to the sea/wind conditions it was not possible to accurately tow the video/stills camera sled at the seabed for the full length of each transect. The camera was instead deployed as a more conventional drop-down camera at each sampling station. Where possible the sea/wind and tidal conditions were assessed and the vessel allowed to drift across the station along the transect with the camera on the seabed. Deployment in this manner allowed for accurate positioning for stills photography at each sampling location, while recording as much video footage as possible.

Suspended sediment loads in the water column close to the seabed along transects F and E (those transects furthest to seaward) on 11th November 2009 were relatively high, and a number of adjustments were made to the angle of the camera and lighting on the

frame to compensate for this. These adjustments had the effect of reducing the field of view by moving the camera closer to the seabed. Image quality was markedly increased following these changes, however, sea conditions on the 12th November 2009 were significantly improved and resulted in superior picture quality. As a result of this stations along transects E and F were re-surveyed.

4.2 Physico-chemical Particle size analysis and TOC results for all stations are presented in Table 4.1.

4.2.1 Particle size Sediment from all of the stations successfully sampled can be classified based on the Udden-Wentworth grain size classification (as per Wentworth, 1922) as sand. In the vast majority of these, gravel (>2mm) and mud (<63µm) fractions were absent and samples consisted entirely of sand (63µm-2mm). However, there was some spatial variation in the dominant size of sand grains present over the survey area.

* Based on Wentworth (1922)

Medium (250-500µm) and fine (125-250µm) sand dominated throughout the survey area, and constituted more than 70% of sediment material at all transects. In general, coarser sand (i.e. very coarse 1-2mm, and coarse sands 500-999µm) were more dominant at transects A (near to the shore) and F (furthest offshore). Whilst a lower proportion of coarse and a higher proportion of very fine sand (63µm-125µm) was recorded at transects B, C, D and the reference stations, in the central part of the pipeline sampling area.

In contrast to the medium and fine sand found throughout the majority of the sampling area, a single station fell under another classification. Station A1 (Figure 4.3) was very coarse sand, based on the presence of around 14% gravel (>2mm) and 36% very coarse sand (i.e. 1-2mm).

Figure 4.3: Day grab sediment sample retrieval from transect A, station 1

Mud (<63µm) was entirely absent from two of the six transects, only occurring in very small amounts (0.02%) at a few stations in transects D and E (0.02%), while it was more obvious at station B4 and in transect C and also at reference stations 1 and 2; the greatest amount of mud (2.27%) was recorded at reference station 1. Both reference stations also contained relatively high levels of very fine sand, indicating slightly less mobile conditions than elsewhere in the survey area, with the possible exception of transect C.

Along any given transect, mean grain size and general sample composition was generally similar, with any exceptions to this usually occurring at the end of a transect.

Table 4.2 shows a summary of the PSA data for the 2009 1-month post-construction survey compared with the 2008 pre-construction survey. Overall there is very little variation in the results between surveys. It can be seen that the median grain size and corresponding Udden-Wentworth sediment descriptions are very similar between years.

4.2.2 Total organic carbon (TOC) Table 4.3 shows the Total Organic Carbon (TOC) levels for the 2009 1-month post-construction survey compared with the levels in 2008, prior to installation of the pipeline. TOC levels in November 2009 were generally low, ranging from 0.03% at station F1 to 0.16% at stations B1 and C2. As levels of TOC are often positively associated with the percentage of fine material present, these data are as expected given the almost complete absence of mud in the survey area and the exposed, high-energy nature of this coastline.

The results are comparable with the levels recorded during the pre-construction survey (RSK, 2009), though generally slightly lower in 2009 than in 2008. Given that the two surveys were carried out at different times of the year, these recorded differences are considered to be minor. The 2009 post-construction survey was undertaken during autumn when higher energy conditions predominate, which could result in coarser grained sediments (associated with lower-levels of TOC) being brought to the surface. This is not however supported in the comparison of the PSA results between the surveys, which indicate no significant changes.

4.3 Interpretation of seabed photography The photographic data obtained provide useful qualitative and supplementary information on sediments and larger biota in the survey area.

The majority of the images show a seabed made up of sandy sediments. These results are as anticipated based on the particle size analysis data, and correspond with the results of the 2008 post-construction survey (RSK, 2009). The majority of sites surveyed exhibit evidence of moderate to high energy wave/current exposure. At these sites sediments are well sorted and show wave/current derived ripple bedforms.

Table 4.4 summarises the key physical and biological features of interest at each transect, based on interpretation of the seabed photography.

Seabed ripple bedforms are present at all transects from A-F, although they are less pronounced at those transects furthest to seaward and closest inshore. Greatest uniformity in bedform sand ripples occurs at transects B-D, where water depths are in the approximate range 20-45m.

Fine-grained sands are the predominant seabed substrate, exceptions to this are observed at Station A1, B6, C6, reference station #1 and #2. At Station A1 (Figure 4.4) sediments are coarse-grained sands with gravels and shell fragments. This station is also close to the cliffs and off lying rocks, as such also within 10m of the target position the seabed is a mosaic of rock and coarse sand (Figure 4.5). The remaining stations on transect A have a seabed comprised fine-grained sands, with evidence of high wave and current energy (Figure 4.6). Between stations A2 and A3 an area of cobbles and boulders is present (Figure 4.19). This is potentially the result of the causeway that was built to construct the pipeline landfall, and the cobbles and boulders observed are consistent with those observed while undertaking the 1-month post-construction intertidal survey at the pipeline landfall in October 2009. The photograph shown in Figure 4.19 was obtained at position 54.285ºN / 9.836ºW (approximately 97m south west of the target position of A3).

Examples of sites on transects B, C, and D can be seen in Figure 4.7 – Figure 4.9. These highlight the nature of the wave/current induced rippled, sandy seabed sediments. Also noted at station B4 was evidence of the recent pipeline construction. Figure 4.18 shows the rock armour that was installed by fall-pipe vessel immediately prior to the survey taking place. The photograph shown in Figure 4.18 was obtained at position 54.285ºN / 9.859ºW, approximately 21m from the target position at B4.

Recorded fauna is very infrequent at transects B-D, with the exception of stations B6 and C6, which have a bedrock and boulder bedform. The fine-grained sandy substrate sites with evidence of strong wave and tidal action, which typify the majority of the seabed throughout Broadhaven Bay are characterised by low abundances and diversity of epibenthic species. The photography recorded very few sightings, although it is important to note that the field of view of the seabed camera is small.

Stations along transects E and F in deeper water exhibit less pronounced sand ripple bedforms, due to the reduced hydrodynamic energy at the seabed. Consequently, increased evidence of bioturbation in the form of small-scale burrows and mounds is observed (Figure 4.10). Despite the increased evidence of bioturbation of the sediments (likely caused by polychaete worms, brittlestars, bivalves or amphipod shrimps), visible and identifiable biota was relatively infrequent over much of the sandy sediments throughout the bay, which is characteristic of this environment. Recorded fauna includes a gadoid (possibly poor cod or whiting (Figure 4.10)), hermit crabs, and brittlestars.

Figure 4.10: Station E5: Bedform sand ripples, resulting from wave/current

activity are less pronounced than at shallower water transects. Seabed sediments dominated by fine-grained sand containing obvious mica particles with

small quantities of shell fragments, burrows and mounds providing evidence of bioturbation. Fish is likely a juvenile gadoid, possibly poor cod (Trisopterus

minutus) or whiting (Merlangius merlangus). Evidence of flock/organic debris is further highlighted

Many of the stations sampled in transect D showed examples of a less energy-intensive environment, for example station D2 (Figure 4.11) where the sand ripples are less regular and non-uniform, indicating a reduced-energy environment. Station D2 shows evidence of more obvious epibenthic activity with noticeable faunal tracks shown imprinted in the sand.

In addition to the majority of sites, which were dominated by sand substrate, some sites were characterised by hard substrate, which fell into two main types. In the shallower and well-lit waters at the northern extremes of transects B and C, the bedrock and boulder substrates are dominated by an epibenthic community of encrusting red algae and red macroalgal species as shown in Figure 4.12 and Figure 4.14. as well as a diverse assemblage of fauna (briefly summarised in Table 4.4).

The second type of hard-substrate environment was observed at the reference stations, in water depths in excess of 50m (Figure 4.16 and Figure 4.17).

Although the physical bedforms in these areas appeared similar to those observed at shallower transects (i.e. bedrock and boulders), the increased water depth (and therefore decreased light penetration) prevents significant plant growth. As such, species of flora are significantly reduced, and the epibenthic community is dominated by faunal species. In addition to increased depth, the reduction in hydrodynamic energy is another factor that has implications for the community that develops at these sites. The visible fauna is briefly summarised in Table 4.4.

5 Summary

5.1 Results of Physico-chemical Analyses The seabed throughout the sampling area was largely dominated by mobile soft sediments. This was almost entirely dominated by sand, with only one station (A1) being distinctly different and consisting of very coarse sand. Within the sandy sediments, some variation was seen in the distribution of various fractions: Coarser sands were more in evidence at transect A (near to the shore) and F (furthest offshore), while a lower proportion of coarse and a higher proportion of very fine sands was recorded at transects B, C, D and E, in the central part of the pipeline sampling area. Fine sediment (mud), and consequently total organic carbon levels, were low throughout the area, as expected for a high-energy Atlantic coastline without major riverine input.

A few areas were recorded as being hard substrate, either through video imagery or the failure of the Day grab to collect a sample. These included the area nearest to the Sruwaddacon estuary mouth (transect A), where 3 stations recorded rocky substrates. At either end of the transects hard rock was encountered, while at the centre of the transect over the pipeline itself stones and cobbles were present (possibly the remains of the causeway used to constructed the pipeline landfall). At the northern extremes of transects B and C hard rock was encountered as well as at the reference stations. The rock armour protecting part of the pipeline was evident at the centre of transect B.

The results from the revisited survey locations (2008 and 2009) show no significant differences. With the exception of direct photograph evidence for pipeline construction observed close to sampling stations B4 and A3, no appreciable impacts resulting from the pipeline could be determined in the results from sediment sampling.

5.2 Results of Seabed Photography Video footage provided qualitative evidence of subtidal environments in the area, and the still photographs were of a very high quality (many of which have been included within this report). Sandy habitats ranged from shallow high-energy rippled sand to more settled conditions with extensive evidence of bioturbation, and the biota associated with these included hermit crabs, brittlestars, gadoids and a swimming crab. Hard-substrate areas in shallow water supported a significant encrusting fauna, which included sponges, anemones, hydroids, bryozoans and crinoids, as well as extensive algal growth.

Hard substrates in deeper waters where hydrodynamic activity was significantly reduced, lacked significant algal growth and were dominated by faunal species. An extensive faunal turf covered rock surfaces, and other notable species included sponges, solitary corals and anemones.

The interpretation of the seabed photography during this survey has not highlighted significant differences compared with the pre-construction survey of 2008. During both surveys photographic evidence supports the results of the sediment sampling, and shows an overall seabed of sand throughout Broadhaven Bay, with hard substrates close to the northern and eastern coasts (reference stations, station 6 on transect A, B, and C, and along transect A).

Significant differences from 2008 that show evidence of pipeline construction were observed at two locations: while targeting station B4 (evidence of rock dumped section of the pipeline) and while targeting station A3 (potential evidence of wash-out from the causeway built to construct the pipeline landfall).

Drop-down photography system

The camera system was based on the Benthic Solutions Ltd. (BSL) 3.4 megapixel digital camera system with video streaming operated through a surface controller and recording unit. The system had the capacity to be supplied with a unique freshwater lens system developed by BSL for operating in conditions with low ambient water clarity.

The key acquisition parameters of the system used were as follows:

Standard Features Comment Image Resolution 3.4 megapixel (2,048 x 1,536 pixels) Light Sensitivity setting ISO 100 Automatically Selected Sensor Type 1 / 1.8” format high density CCD sensor

Light source 2 x 250lumen controllable LED lamps Stills strobe TTL controller

Typical settings on this survey Aperture priority at F7.4, Shutter speed typically 1/60th or 1/125th second, Auto flash mode

Framing Video Used 625 Line / 50 Hz PAL Control System BSL trigger and surface monitoring system Other Systems Freshwater Lens system (optional use)

The system was deployed from the stern of the vessel using a vertical drop-down frame technique and lowered to the seabed using the vessel’s winch. Height above the seabed was monitored using the online video to control the frames attitude once at the seabed. The seabed was surveyed using a combination of video (minimum 2 minutes) and digital stills photographs (minimum of 5 shots per site). Positioning of the system was based on an offset centred on a vertical deployment from the stern of the vessel.

All data were recorded to DV video and later transferred to DVD via firewire into a PC. Stills images have been reviewed and positions annotated to a separate survey file (Annex 3). The camera system was particularly useful in recording the heterogenic material found at the reference locations, along with stations A1, B6 and C6, some of which could not be sampled using standard grab sampler due to the nature of the seabed.
