JP KENNY SW WAVE HUB - METOCEAN DESIGN BASIS

REPORT NO: 2056, REV 01 FILENAME: P1209A / TMAR50_REV1.DOC

SUMMARY This report provides the metocean design basis for the shore export cable of the SW Wave

Hub Project, an offshore facility that will allow wave energy conversion devices to connect to

the National Grid. The Wave Hub will be located north of St Ives in a seafloor depth around

50-60 m. The export cable will come ashore in St Ives Bay, a route of 24.5 km. The Project

is owned by the SW Regional Development Agency (SWRDA), which has commissioned JP

Kenny to manage the design and installation of the cable.

This work is carried out under authorisation of JP Kenny Service Order No 6600-e dated 19

February 2009 and the terms of the General Agreement for Provision of Consultancy and

Technical Services between JP Kenny and Metoc dated 9 August 2004.

Metocean design criteria are provided at 15 locations along the cable route between KP1.25

(chart depth 1 m) and the hub. They include waves, current, water levels and seawater

properties. Values are given in eight directional sectors for monthly cases with 1 year return

period and all-year cases with return periods 1, 10, 50 and 100 years. Operational wind data

(monthly exceedence of wind speeds) are also provided.

Wave criteria have been prepared by wave refraction modelling. For waves approaching

from the ocean, model inputs are extreme sea states at the model boundary, calculated from

Met Office model archive data; the model simulates the transformation of wave properties

due to changing bathymetry with progress shoreward. For sheltered sectors (E, SE, S)

extreme winds are input and the model calculates wave growth. Site specific wave

measurements, collected at the Wave Hub, have been made available to help define wave

characteristics.

Current and water level criteria have been prepared using data from a selection of models

operated by Proudman Oceanographic Laboratory (POL) in conjunction with a hydrodynamic

model that Metoc runs in-house.

The metocean criteria presented here are intended for use in final engineering design of the

cable.

In parallel with this report, Metoc has conducted a cable burial depth study, reported

separately (Metoc Report 2057).

1 INTRODUCTION

1.1 OBJECTIVES

JP Kenny is designing and managing the installation of the export power cable for the Wave Hub Project, an offshore facility that will allow wave energy conversion devices to connect to the National Grid. The Wave Hub will be located north of St Ives in a seafloor depth around 50-60 m. Its export cable will come ashore in St Ives Bay, a route of 24.5 km.

This report provides the metocean design basis for the cable. The work is carried out for JP Kenny under authorisation of their Service Order No 6600-e dated 19 February 2009 and the terms of the General Agreement for Provision of Consultancy and Technical Services between JP Kenny and Metoc dated 9 August 2004.

The Wave Hub is exposed to the Atlantic Ocean and therefore is subject to considerable wave action from the west and southwest; the shore end of the route benefits from comparative shelter within St Ives Bay.

Figure 1.1 sketches the locations of a selection of the metocean data used in this study.

Figure 1.2 below shows the locations for which metocean criteria are provided here. Locations within St Ives Bay are defined by seafloor depth; those outside the Bay are defined by chainage.

1.3 APPROACH

Metoc prepared these design criteria using a mature methodology that is well recognised throughout the offshore industry. It is consistent with guidance published by HSE (2001) and the international metocean standard ISO 19901-1.

Wave measurements near the hub have been examined to provide information on wave steepness and wave spreading.



2 WAVES

2.1 EXTREME WAVE PARAMETERS

Tables 2.1a-d present extreme wave parameters with return periods of 100, 50, 10 and 1 year.

Appendix Tables A1-A12 give monthly extremes with a return period of 1 year. Monthly values are derived from 3-month seasons centred on the desired month (e.g. extremes for July are based on data for June, July and August).

Values are given in eight directional sectors centred on the cardinal points. Wave parameters are as follows:

Hs Significant wave height

Tz Mean zero-upcrossing wave period

Tp Spectral peak period

Hmax Maximum individual trough-to-crest wave height in 3 hours

Tmax (range of) wave period associated with Hmax

Gamma, the spectral peakedness parameter

Table 2.1e shows the wave spreading parameter, s, which may be used in conjunction with these extremes. Separate values are given for winter (Oct-Mar) and summer (May-Sep).

Appendix B shows relevant outputs of the wave refraction model.

2.2 FATIGUE WAVES

Table 2.2 shows the total number of individual waves in a year at the wave hub. The annual number of waves at the wave hub has been derived from the average wave period seen in wave rider buoy data collected at the site. Numbers are broken down by direction sector, inferred from the Met Office model data.

Numbers of individual waves within each height class are calculated by distributing the total number from zero height to 1-year extreme Hmax in a negative exponential distribution.

Table 2.3 shows non-directional numbers of waves in a year at other parts of the route.

2.3 OPERATIONAL WAVES

Table 2.4 shows monthly exceedence of significant wave height at the hub. The values are based on 8 years of data from the Met Office UK Waters model at a grid point close to the hub.

Tables 2.5a-e are joint frequency distribution tables of significant wave height versus wave direction; for all year and by season.



3 CURRENT

3.1 PRESENTATIONS

Tables 3.1.1-3.1.15 each provide a full suite of extreme current criteria for one location along the cable route. The locations correspond to those provided for extreme wave criteria.

Each table shows directional currents at surface and at 1 m height above seafloor; annual values are given for return periods of 1, 10, 50 and 100 years, and monthly values are given for 1 year.

The tables also show location identifiers, tide and surge parameters and the profile shape assumed to apply. The profile follows a 1/10th power law (speed varies as the 1/10th power of variation in height) in the lower 70% of the water column. Above that height, speed is uniform to the surface.

Current roses with each table show the mean spring tidal ellipse, 50-year surge in 8 direction sectors and their combined total (which exceeds the sum of their parts). Tide-and-surge combinations have been derived using factors empirical to the nearby standard port of Newlyn.

3.2 SUPPORTING INFORMATION

Metoc built a high-resolution 2-dimensional hydrodynamic model to simulate tidal streams within the area surrounding the cable route. The model is driven at its boundaries by tidal elevations prepared from Proudman Oceanographic Laboratory’s (POL’s) CS20 model. It is validated at its interior, i.e. several points along the cable route, against CS20 tidal currents. Metoc analysed harmonic constituents from one year of CS20 data at several sites on the offshore boundary and along the cable route.

3.3 COMPARISON AGAINST OTHER SOURCES

Metoc has calculated surface current velocities from observed trajectories of surface drifters in and around the study area. A limited number of data are available; the drifters generally move at around 0.2 m/s and the highest speed seen in the data was 0.65 m/s (values are averaged over 6 hours).

Figure 3.1 below is a sketch map showing the area covered and the reported tracks; the higher speeds were comparatively close to the hub area.

4 WIND

4.1 OPERATIONAL WIND

Table 4.1 shows the monthly exceedence of wind speeds applicable at the wave hub and in the general area away from the shore. The data were measured at Seven Stones Light Vessel over the period Sep 2001- Jan 2009.

Metoc has reviewed the data quality and found the data to be of an acceptable standard for the present study. They show slightly higher speeds than the UK Met Office Model, which is probably due to the model’s spatial averaging.

[The same data have been used to derive extreme wind speeds for input to the wave refraction modelling wind-driven cases].



5 WATER LEVELS

Table 5.1 presents a full suite of water levels at the wave hub. These include all standard tidal heights, storm surge combined (tide and surge) total still water levels, and extreme including wave crests for 50- and 100-year return periods.

Table 5.2 gives the equivalent information near the shore end of the route (KP 1.25). The tide and surge levels show little variation along the route; only wave crest heights differ markedly. Spatial variations of both tide and surge have been checked against, and are consistent with, their disposition as seen in references such as HSE, 2001.

Note that Lowest Astronomical Tide (LAT), which occurs every 19 years, is actually lower than the 100-year extreme low water level. This apparent paradox arises because LAT is substantially (0.4 m) lower than the tidal level (MLWS) assumed to contribute to the joint tide-and-surge extreme. The n-year extremes should be used in conjunction with extreme sea states, whereas LAT is more appropriate when considering water levels in isolation.

Tidal heights are scaled from the nearby standard port of Newlyn to the site in the ratio of their tidal amplitudes. Those for the site are determined by harmonic analysis of data extracted from Metoc’s hydrodynamic model.

Storm surge heights are derived from POL’s Continental Shelf Model, which has simulated storm surges throughout UK waters during a selection of severe historical storms.

Extreme water levels are determined by combining high tide and storm surges in a ratio empirical to Newlyn. Wave crest elevations are derived from wave height, wave period and water depth using a formulation attributed to Tung and Huang, modified by Tucker.



6 SEAWATER PROPERTIES

Table 6.1 illustrates the variation of seawater properties with depth. Note that the data extend beyond the maximum depth of the cable route; assume that values seen at a particular depth are valid at that depth throughout the study area.

Table 6.2 illustrates their variation with time of year (showing all depths together).

Table 6.3 tabulates the monthly variations of seawater temperature. Values are given for separate depth ranges.

The presentations are based on more than 12,000 data collected by scientific institutions during the last century (1909-2007) in a small area around the site (49-51°N, 5-7°W).

The original data comprise temperature, salinity and depth. Metoc has derived seawater density from these using algorithms published by UNESCO.

SW Wave Hub Shore Export Cable - Metocean Design Basis

Notes

Intended for use in engineering design of seabed cableExtreme Hs and Tz are generated by wave refraction model MIKE21The model calculates the transformation to shore of extreme waves input at its offshore boundaryWhere more applicable, it calculates waves using principles of wind-generated wave growth (whole route for sectors E, SE and S, and sheltered parts of route for sectors NE, SW and W)

Other wave parameters are derived from Hs and Tz using industry-standard relationships: Tp = 1.27*Tz Hmax is calculated from Hs and Tz for 3 hr storm duration according to Rayleigh theory; limited to 0.78 depth Lower Tmax/Tz ratio 1.05; Upper Tmax/Tz ratio 1.40; Central Tmax is same as Tp Gamma derived fron Hs, Tp using formulation given in offshore standard DNV-OS-J101Wave boundary inputs calculated from European Wave Model at 50.7°N 5.7°W Nov 1988 - Nov 2008European model data (joint frequency tables) purchased under licence from UK Met OfficeWind inputs calculated from Seven Stones Light Vessel observations 50°6'9"N 6°6'0"W Sep 2001 - Jan 2009

Notes

Intended for use in engineering design of seabed cableExtreme Hs and Tz are generated by wave refraction model MIKE21The model calculates the transformation to shore of extreme waves input at its offshore boundaryFor waves moving offshore (e.g. from east) it calculates wind-generated wave growth

Other wave parameters are derived from Hs and Tz using industry-standard relationships: Tp = 1.27*Tz Hmax is calculated from Hs and Tz for 3 hr storm duration according to Rayleigh theory; limited to 0.78 depth Lower Tmax/Tz ratio 1.05; Upper Tmax/Tz ratio 1.40; Central Tmax is same as Tp

Gamma derived fron Hs, Tp using formulation given in offshore standard DNV-OS-J101Wave boundary inputs calculated from European Wave Model at 50.7°N 5.7°W Nov 1988 - Nov 2008European model data (joint frequency tables) purchased under licence from UK Met OfficeWind inputs calculated from Seven Stones Light Vessel observations 50°6'9"N 6°6'0"W Sep 2001 - Jan 2009

Appendix B Wave Model Plots


REPORT NO: 2056, REV 0 B-2 29/04/2009 FILENAME: P1209A / TMAR50.DOC

Explanatory Note

This Appendix contains images of the spatial distribution of 100-year extreme wave height throughout the model domain for each of the 8 directions simulated.

In each case the model domain is configured to suit the direction sector. Wave height magnitudes are indicated by colour coding while black arrows depict the direction of wave travel at intervals throughout the domain. The proposed cable route is also shown for reference.

Images are as follows:

B1 100-yr from N

B2 100-yr from NE

B3 100-yr from E

B4 100-yr from SE

B5 100-yr from S

B6 100-yr from SW

B7 100-yr from W

B8 100-yr from NW
