The overall purpose of the submarine survey is to identify optimal seabed conditions in the form of a flat bottom with soft sediments and no obstacles along the route. The investigation of seabed conditions is being conducted in preparation for the installation of an undersea cable (note: an optical cable with a diameter of approximately 25 millimeters), with the aim of identifying potential obstacles as well as any cultural heritage remains, ensuring a long-term stable installation. The purpose of the hydrographic survey is to enable an increase in telecommunications capacity to and from Sweden. The survey will make it possible to plan the optimal route that GlobalConnect plan to establish the additional optical cable between Saeby (DK) and Lerkil (SE). The additional cable is planned to be laid parallel to the existing cable. The reason for the planned cable lay is to increase capacity and redundancy.

This application is sent in aim to get permit approved for the survey equipment SubBottom profiling (sub-bottom penetrating sonar) (SBP), Grab Samplar (5-10 test points) and Video/Photo if needed.

One of the types of survey equipments that will be used for survey is SubBottom profiling (sub- bottom penetrating sonar) (SBP) – will be used for survey aimed at facilitating cable burial if the need or requirement arises.

The Survey will be carried out between Lerkil (SE) and Saeby (DK). Appendix 1 showing of planned cable route and coordinate list. Survey corridor width between 100 – 150 meters

Introduction

Application for submarine survey permission by using survey equipment Sub Bottom Profiler in Danish Territorial Sea and Economic Zone (EEZ), to prepare to the application for permission to lay optocable between Seaby, Denmark and Lerkil, Sweden.

CLAIMS

Global Connect AB requests that the Kystdirektoratet grant permission to carry out a submarine survey including Sub Bottom Profiler and Grab sampler as equipment in the Kattegat, within routes/areas according to coordinates specified in Appendix 1 Saeby (DK) - Lerkil (SE). Hydrographic survey permits for the same route is granted by Geodatastyrelsen including survey equipments Multibeam (multibeam echo sounder), SideScanSonar (side- scan sonar), Magnetometer/Gradiometer (registration number/case number GST-300-3513). GlobalConnect AB requests that the permit shall be valid for 2 years from the date of the permit and that the permit be subject to the conditions as proposed below. The claim does not include geophysical surveys where frequency ranges below 200 kHz occur during the period 1 May to 31 August.

Draft terms and conditions

When starting up underwater sound survey equipment, observers are used to scout for marine mammals such as porpoises and seals to ensure that they are not in the vicinity of the survey vessels. When using equipment that emits sound with a frequency below 200 kHz, so-called soft start-up of the equipment must be applied. To avoid the main calving period for porpoises (May-August), surveys with sub bottom profiles are carried out during the period September to April. Instruments or other equipment must not be left behind after the investigations have been completed. Spills of oil and other harmful substances should be avoided as far as possible. All survey vessels are equipped as standard for oil clean-up. Dumping of waste in connection with the work must not take place. Lost geotechnical and geophysical equipment shall be recovered as far as possible and reasonably. Investigations of the presence of ancient monuments must be planned together with maritime archaeological expertise. Information about ancient monuments that emerge during the investigation work must be reported initially to Geodatastyrelsen and Kystdirektoratet, in order to be guided to the supervisory authority. Analysis of survey data shall be carried out in consultation with the authority and maritime archaeology expertise.

About the applicant

GlobalConnect AB is one of the leading providers of digital infrastructure and network services in the Nordic region. The company is headquartered in Copenhagen, Stockholm, Oslo, Helsinki and Hamburg. GlobalConnect employs approximately 2,000 people and provides 30,000 business customers and 800,000 households with network services and fiber connectivity. The company has 235,000 km of its own fiber network. GlobalConnect AB is owned by EQT.

Background and purpose of the application

The company plans to lay a fiber cable with a route between Seaby in Denmark and Lerkil in Sweden. The company has identified a suitable cable route mainly parallel to the company's existing fiber connection between the same land points. The survey distance within Denmark's territorial sea and in Denmark's economic zone is about 49 km + 6 km long with a varying corridor width of between about 100 – 150 m. In order to obtain the documentation required for the assessment of a suitable cable route and the preparation of environmental impact assessments for future permit processes, the company needs to carry out a number of investigations and inventories. A central part of this work is to implement geophysical surveys of the seabed, e.g. to gather knowledge about the seabed area and different sediment types, as well as to identify and position nearby existing pipelines, any wrecks, larger boulders, mountains in the open or unexploded munitions. The information from the surveys will then be used in the further planning and design of the cable route. The company therefore applies to Kystdirektoratet for a submarine survey permit through the current permit application.

Survey route / area

The surveys will be carried out in the northern part of the Kattegat, between Denmark and Sweden, figure 1. The route on which the investigations will be carried out is hereinafter referred to as the planned cable route and is shown in Figure 2 and information in Appendix 1 Saeby (DK) - Lerkil (SE). Permits have already been submitted to Swedish authorities for the Swedish Territorial water and Swedish EEZ.

Figure 1 Planned Cable route between Seaby in Denmark and Lerkil in Sweden. The corridor 100-150 meters for surveying will be around the red line presented on the map.

Figure 2 Planned Cable route between Seaby in Denmark and Lerkil in Sweden. Map showing the part on the Danish Territorial water and EEZ. The corridor 100-150 meters for surveying will be around the red line presented on the map.

After searching databases, no nature protected areas have been found on the planned route and corridor. The same applies to ancient remains and wrecks, none have been found in databases. Military areas have not been investigated, due to the difficulty of finding data.

Planned Survey

The surveys planned are geophysical surveys. The type of measuring equipment, purpose and results of the surveys are shown in table 1. There is also a description of the dominant frequency range and expected sound level of each survey method. The surveys will mainly be carried out from ships and smaller boats. The geophysical surveys cover the entire survey route/area, while any sediment samples are taken at a smaller number of points. The following methods may be used:

• Sub Bottom Profiler: SBP
• Multibeam Echo Sounder: MBES
• Side Scan Sonar: SSS
• Magnetometer
• Grab Sampler
• Video/photo Table 1 Equipments will be used during the submarine surveying.

At the present time, it has not been decided in detail what equipment will be used in each investigation or where the possible sampling points for sediment examination will be. The number of samples has not been decided at this stage either, but it is estimated that there are about 5–10 test points and the examinations will last for a total of about a week. Each sample will be no larger than 3-6 liters. Overall, it can be said that the measurements will emit continuous, non-impulsive sounds, both low and high frequency, and with a sound level of up to a maximum of 209 dB re 1 μPa @ 1 m, (1 m from the sound source centrally in the main lobe's main axis).

Time for when the surveys will be carried out

Investigations are expected to last in the field for a total of about a week. Since all surveys are dependent on prevailing weather conditions, the schedule is an estimate and the surveys may need to be paused or delayed, which may mean that they need to be carried out for longer extended calendar time. In addition, the ongoing investigations depend on the possible cumulative impact of other actors in the area, such as other exploration vessels or commercial fisheries. In view of the difficulties in establishing a detailed timetable when the investigations may be carried out, the company requests a permit period of two years. Equipment, products, etc. The surveys themselves generate limited or no emissions. Dumping of waste in connection with the work must not take place and no instruments or equipment may be left in the investigation area after the completion of the work. Spills of oil and other harmful substances shall be avoided as far as possible and any lost equipment shall be recovered as far as possible and reasonably. All survey vessels are equipped as standard for oil clean-up.

Environmental assessment

In summary, the assessment is that the planned investigations, with proposed conditions and protective measures, will not have a significant impact on the environment or marine mammals, birds, fish or fisheries in the area. No potential significant impacts are expected to occur on plants or mammal’s environment. Any sampling points in regional and national environmental monitoring are also not expected to be affected.
