Jørn Bo Larsen Phone number: 516186 63 Email: [email protected] Project description Note: A full project description is provided in Chapter 4 of attachment 1: Project description and environmental screening, Denmark The cable The cable type to be used is an Alcatel OALC 4 cable, which is a resilient cable type designed specifically for repeatered systems. A ‘repeatered system’ is a cable system typically longer than 350-400 km. To prevent the optical signal deteriorating from the point of origin to the destination, the signal is boosted approximately every 70 km in a repeater. The cable itself is between 25 mm and 40 mm in diameter, depending on the level of cable armouring. At the heart of the cable is the fibre unit structure, where the optical fibres are set in a steel tube and are protected by a jelly from water penetration and hydrogen. The cable is insulated with high-density polyethylene; the insulation also provides abrasion resistance. In shallow water (normally <1000m water depth), the fibre unit and insulation sheath are protected by galvanised steel wires and layers of black polypropylene yarn for additional protection against external threats (known as armouring). The entirety of the cable within Danish waters will be fitted with armoured protection. Reason for establishing the cable The Havhingsten cable project will create a diverse connection between Denmark and the UK, along with an additional connection in the Irish Sea between the UK, Isle of Man and Ireland. The cable system will provide ‘carrier neutral’ access to the EU and UK telecoms networks, which allows interconnection between multiple telecommunication carriers and/or providers bringing competitive access from large telecoms providers. The cable will support the needs of the web-scale providers that underpin today’s international cloud industry. The route will enable connectivity for global carriers, cloud-based networks, data centres, information technology (IT) companies and the global media. There is increasing demand for high-capacity connectivity linking Northern Europe, and the Havhingsten project will facilitate this in combination with existing fibre optic routes. Havhingsten will deliver a reliable and resilient connection to support the rise of the European digital economy. It therefore will benefit the socio-economic conditions within each of the countries in which it lands, including Denmark.

The cable route has been engineered to avoid potential hazards, reduce impact to seabed users such as disruption to marine resources and operations, and secure long‐ term protection of the cable. The cable route and project design are developed and refined through two main stages: • A Cable Route Study – detailed review of all factors affecting the routing of the cable, including physical, environmental, socio-economic, and regulatory aspects • A Cable Route Survey – surveys of the inshore and deep-water sections of the route. The whole offshore cable route is presented in Figure 1, while a zoom on Danish waters is presented in Figure 2. The marine elements of the cable route are proposed to cross the Irish Sea from Loughshinny (north of Dublin in Ireland) to Squires Gate Lane (south of Blackpool on the west coast of the UK). The marine cable route will then continue across the North Sea from the Seaton Sluice (on the east coast of the UK, north of Newcastle), to Houstrup (on the west coast of the Jutland peninsula in Denmark). Two marine cable route branches from the Irish Sea section to the Isle of Man are included to landing points at Port Erin and Port Grenaugh. An additional stubbed cable route is included north of Houstrup (landing at the parking area at Gammelgab) out to the Danish TW boundary for future extension. The stubbed route will be installed to provide an alternative landing in Denmark. This additional landing will offer diversity from the main cable route by means of a future extension. In order to facilitate the future extension, the installation of the stubbed route out to the Danish TW boundary is planned at the same time as the installation of the main cable route. This approach will improve efficiency of installation, provide a more economically viable future extension, and reduce the level of disruption that two separate installations would cause. The additional stubbed route will provide further high-capacity connection to Denmark and Northern Europe. The landing point for the stubbed route has been selected as it is a sufficient separation from the main route to provide a viable alternative in the case of cable damage. Both cables in the same trench and at the same landing point would not offer a viable diverse route in case of cable damage or failure. A route to the south of Houstrup was investigated but was ultimately not considered to be viable as there is existing and future wind farm development in this area. The additional stubbed cable route landing at the parking area at Gammelgab (north of the main cable), will consist of a BMH and a cable installed out to the Danish TW boundary. The stubbed cable will remain in the seabed outside of the TW boundary at the end of the installation operation, ready to be recovered at the time of future extension. It is intended that this stubbed route will be extended in the future to provide additional connection to Denmark. The options for this cable extension are under review, but the provisional plan is that this stubbed route would be extended within 10 years from completion of the Havhingsten project. The length of the main data cable within Danish waters is approximately 315 km, while the length of the northern stubbed cable within Danish waters is 25 km. The length of the fibre optic cable from shoreline to the BMH is approximately 0.44 km for the main cable route, and 0.43 km for the additional subbed cable route. Cable lengths in Danish waters are presented in Table 1. A depth profile along the cable route in Danish waters is presented in Figure 3.

Study on international Internet connectivity in sub-Saharan Africa Foreword It is my pleasure to introduce this report on International Internet Connectivity (IIC) in sub-Saharan Africa; this is part of a series of regional reports that address the present situation of Internet connection as well as future developments and challenges. These reports have been developed through collaboration between the ITU Telecommunication Development Bureau (BDT) the Telecommunication Standardization Bureau (TSB) in view of supporting policy makers, national regulatory authorities and operators in understanding the many aspects of international Internet connectivity. The digital revolution of the 21st century is being underpinned and in many cases driven by the growth, access and use of the Internet, but it has also led us to a modern indicator of division and poverty: exclusion from this revolution, from access to the Internet or telephone, and from the benefits of today's information society.

    The Socio-Economic Impact of Broadband in sub-Saharan Africa: The Satellite Advantage The Socio-Economic Impact of Broadband in sub-Saharan Africa: The Satellite Advantage By the Commonwealth Telecommunications Organisation Page 1 The Socio-Economic Impact of Broadband in sub-Saharan Africa: The Satellite Advantage Executive Summary Broadband is not just a consequence of economic growth, it is also a cause. Sub-Saharan Africa has succeeded in the last decade in bringing voice services within the reach of some three quarters of the population, but the vast majority of the region is falling further behind the rest of the world in terms of broadband connectivity. There are two main reasons for this: supply is limited, and prices have been very high.1 Broadband is the delivery of Internet IP bandwidth (at speeds of 256 Kbps or more), and all of the content, services and applications which consume this bandwidth. The essential underpinning of broadband therefore is the need for a high capacity transmission backbone network capable of delivering this bandwidth. Providing an entry level 256 Kbps broadband service to hundreds, thousands or millions of customers requires a backbone transmission network with sufficient capacity to do so. And each time an operator increases its broadband service from 256 Kbps to 512 Kbps, 2 Mbps, or even 100 Mbps, this in turn escalates the capacity requirements of the transmission backbone network. The evolving broadband geography of sub-Saharan Africa reflects changes in the underlying level and pattern of supply of this trunk transmission capacity, and the pricing of that capacity. All of Africa’s international Internet bandwidth is supplied by satellite, submarine cables or terrestrial networks connected to submarine cables.

    Developing Rural Mobility A CASE STUDY OF ALSELV By Mia Lodberg Vibe-Hansen, 20191883 MSc4 Mobilities & Urban studies Group: Ma4-urb19 Submitted 26.05.2021 Developing Rural Mobility A CASE STUDY OF ALSLEV BY MIA LODBERG VIBE-HANSEN SUBMITTED 26.05.2021 _________________________________________________ Student: Mia Lodberg Vibe-Hansen, 20191883 _________________________________________________ Supervisor: Claus Lassen 1 I Abstract Today there is an imbalance between the cities and the rural areas in Denmark. Many of the municipalities placed in rural Denmark are struggling with an increasing opt-out of their cities, which affects many areas within the municipality. The challenges of shrinking cities in rural areas are often seen in a generalizing and overall perspective, making it difficult to see the potentials within the individual city. Approached by a cross disciplinary mobilities perspective that is included in the new mobilities paradigm (Urry 2000), this project aims to explore the city of Alslev in Varde Municipality, in relation to the challenges of shrinking cities in rural Denmark. To see, if by adding a mobilities perspective, could unfold the city in a new perspective, which could give rise to new potentials and extend the knowledge upon which urban planners explore a city, and hopefully bring something new to the discussion of developing the rural areas within the municipality. By analysing the rural mobilities of Alslev, it will be studied how Alslev performs as a ‘place’ to identify what are the strengths of Alslev, and what could have potential for improvement. With a focus on everyday life, the citizens of Alslev’s everyday activities are used as a focal point for the mobilities perspective.

GENERAL DESCRIPTION OF THE AREA 1.1 Physical process level 1.1.1 Classification The Danish coastline is 7400 km long. There are three different types of coast in Denmark: 1. Tidal coast protected by sea dykes; 2. Highly exposed North Sea coast; 3. Less exposed coasts of Baltic Sea and Kattegat. The Western coast of Jutland belongs to the highly exposed North Sea coast. The typical Danish coast facing the North Sea is a sandy beach, in front of dune ridges. The west coast of Jutland is a shoreline of adjustment controlled by promontories and with embayments protected by offshore bars. It is typified as a highly exposed micro tidal sandy coast, according to the typology in the scoping study: 3a. Wave dominated sediment. Plains. Fig. 1: Location of case area. Dune coasts in micro-tidal zones. 1.1.2 Geology During the Pleistocene glaciations, Denmark was an area of peripheral accumulation in contrast to Norway and Sweden, which mainly constituted an erosion area. The Scandinavian ice sheet did not cover the whole of Denmark during the Weichselien; it’s western margin stopped in northwestern and central Jutland. The surface of southwest Jutland is dominated by sediments of the Saalian glaciation, while deposits of the Weichselien glaciation form the surface layers in the northern and eastern Denmark.
