BalWin1 (formerly LanWin1) and BalWin2 (formerly LanWin3) are the names of the two new offshore connections that feed renewable energy from wind farms in the North Sea to Wehrendorf in Lower Saxony and Westerkappeln in North Rhine-Westphalia into our transmission grid. For both systems, cables will initially be laid on the high seas, in the mudflats near Norderney, and on the mainland between Hilgenriedersiel on the coast and the two grid interconnection points in Lower Saxony and North Rhine-Westphalia. For the most part, they are to be laid in parallel, safely and as environmentally friendly as possible. Both the closed and the "open" construction methods are possible. Amprion commissioned DAHLEM in a joint venture with the planning of an approx. 135 km long underground cable - direct current transmission system (525 kV) from Bösel to Wehrendorf and Ibbenbüren with the rough and fine routing up to and including the submission of the permit application.

On April 24^th, 2023, as part of the annual series of events of the BIM2Water initiative, a presentation event with an interactive panel discussion will be held on the topic of "BIM in Water Management - Regulations and Practice" at the Hilton Hotel in Düsseldorf, from 11:00 - 17:00h. In addition to numerous practical examples, the participants will gain insights into the current developments of the regulations. Furthermore, the event offers plenty of space for exchanging experience and obstacles in the implementation of BIM in the water industry. DAHLEM is one of the cooperation partners of the BIM2WATER competence initiative, which provides targeted and needs-optimised support to stakeholders in the water industry for digital planning, construction and operation of BIM methodology.

It is the central national and international meeting place for water management experts: the 56^th ESSEN CONFERENCE on Water Management, which will take place from 7 to 9 March 2023 at the Eurogress Aachen. This year's motto of the conference is "Safe water management in times of crisis". A special trademark of this three-day series of events is the broad spectrum of topics offered, ranging from perspective, environmental policy and legal developments to problems and technical innovations in water management. For many years, the conference has been one of the most important events in the field of water management in Germany and has established itself as a meeting place for experts from the water industry for over 50 years. Accompanying the conference, DAHLEM will be represented with an information stand. Here, university graduates and visitors of the conference are welcome to inform themselves about current and future-oriented topics related to our engineering services.

For her bachelor thesis "Calculation of flood areas for the stream in Heppenheim and evaluation of the results in comparison to an existing heavy rainfall hazard map", Ameli Brecht received the sponsorship award from the sponsorship association of the Department of Hydraulic Engineering and Water Management at the Technical University (TU) Darmstadt. Ms. Brecht started her studies at TU Darmstadt in October 2017. Following her 12-week internship in 2020 at DAHLEM, Ms. Brecht wrote her bachelor thesis, which was supervised by DAHLEM employees. Since then, she has been working as a student trainee in project implementation: "The internship at DAHLEM showed me how varied and exciting everyday life at an engineering office can be. I am therefore happy to be able to continue my work here and especially grateful for the great colleagues.“

There were 6,283 running enthusiasts who finished the Essen 2022 corporate run in beautiful weather. This is already the 10^th Essen corporate run for the DAHLEM running community. In glorious running weather, the Essen 2022 corporate run was on the agenda for over 8,800 registered participants on Wednesday, 22^nd June. The runners covered a five-kilometre course, from Huyssenallee at the Philharmonie to the Tummelwiese at the Grugabad. And once again the motto was: “With each other - for each other”. A highly motivated DAHLEM team went to the start again. "Taking part and reaching the finishing line is our motto". From 7:00 p.m. the starting line was filled with running enthusiasts on Huyssenallee. The distance could be covered running or walking. It is not about the competition between the companies, here everyone comes together to enjoy the sporting event with a lot of fun and the highest level of commitment.

Climate change and global warming will continue to increase according to the IPCC report. Heavy rainfall with major flooding and high water have been showing this very clearly for years. To protect against extreme heavy rainfall, heavy rainfall hazard maps are created in the course of hazard analyses. For this purpose, the state of Baden-Württemberg (LUBW) developed a standard reference procedure that assesses the quality requirements of engineering offices with regard to hazard analyses and heavy rain hazard maps, which are described in the guideline for municipal heavy rain risk management. For successful participation in the standard reference procedure, LUBW issues a quality certificate, which is a prerequisite for submitting bids to municipalities. DAHLEM has been active in heavy rainfall risk management for more than 15 years and again received certification for its participation in the standard reference procedure "Determination of heavy rainfall hazard maps". The standard reference already acquired with the software GeoCPM has now been successfully completed again with the innovative software Visdom, so that at DAHLEM two simulation models for heavy rainfall assessments according to the guideline are available - tailored and optimized to the requirements of our clients.
