Hotel Update for Spring 2025 Meeting

Reservations for the ICC meeting hotel (Louisville Omni) have closed and the ICC-discounted hotel room block has been sold out.

We typically have some ICC hotel reservation cancellations as we approach the meeting.

If you would like to stay at the ICC hotel at the discounted group rate, please contact Jennifer Quandel by email and provide your check in/out dates to be put on the wait list. She will try to accommodate you as rooms become available.

If you no longer need your existing Omni hotel reservation, please do not cancel your reservation with the hotel directly. Instead, send Jennifer your reservation confirmation and she will cancel it on your behalf and assist another attendee that is on the waiting list for a room at the Omni. 

Jennifer Quandel can be reached via email at: JQuandel@hpnglobal.com

ICC Overflow Hotel Information:

We have arranged for a nearby overflow hotel at an ICC discounted group rate of $179.00/night (plus taxes) from May 16 (Friday) thru May 22 (Thursday). The hotel is approximately a three-minute walk to the Omni.

Discounted rate reservations will be accepted until May 8 (Thursday) or until the overflow room block is sold out. When making reservations, please pay careful attention to the reservation and cancelation policies as they are different from the ICC hotel.

Important Reminders for the Spring 2025 ICC Meeting

Hotel Reservations:

Advance hotel reservations discounted for ICC attendees will close on April 25 (Friday).

ICC Meeting Registration:

Advance ICC meeting registration will open on April 14 (Monday) and will close on May 9 (Friday).

In addition to minimizing time at the registration desk so you can quickly start enjoying the meeting, there is a much lower cost for Advance Registration.

Registration for the “Tabletop” exhibit space will also open on April 14. Spaces are limited so early registration is recommended.

C37D Submarine Cable Spring 2025

Discussion Group C37D on Submarine Cables will have several presentations at the spring meeting. These include:

“Inter array cable size optimization case study / CAPEX vs Total Ownership Cost” by George Georgallis, Hellenic Cables

Abstract: “In recent years Offshore Wind Farms have grown rapidly in power- some exceeding 1 GW-  and wind turbine number per farm – 40 to 80+ –  and their numerous configuration possibilities have motivated the use of optimization techniques. This presentation considers a case study using such an optimization formulation to find the techno-economic optimum for the cable sizing in string feeders. This is succeeded by minimizing the sum of capital and operational costs, with the latter being calculated by more accurate loss estimation formulae compared to the relevant IEC standard. In the base reference case, the cables are initially dimensioned to optimize CAPEX by just fulfilling the ampacity requirement. It is concluded that a more cost-effective solution by the end of service life can be achieved by the proposed method.

Title To Be Determined, by Dr. G.J. Anders

Abstract: When a 3-core submarine cable enters the land portion of the route, the armor is stripped and grounded. From that point until a transition joint, the three separate single core cables are laid in the ground, usually in a flat formation. The distance between the armor grounding point and the transition joints is usually short, up to 5 m. In the standard cable design procedure, it is assumed that the great length of the submarine cable limits the sheath circulating currents throughout the entire run of the circuit. However, since the single-core cable in the land section have increased spacing between the phases, the currents which are generated in this part of the route are much larger than in the section of the submarine cable far away from the shore. Combination of the 3-core submarine cable with semiconducting jackets around the cores and the three single core cables in the land portion results in a substantial increase of the circulating sheath currents in the submarine cable as well. These currents and their effect on the cable temperature will be presented on an example of a 220 kV 3-core export cable..

Since this effect results in a significant temperature increase, general recommendations for a reduction of the end effects in submarine installations will also be discussed.

Spring 2025 ICC Hotel

Hotel reservations for the Spring 2025 ICC meeting in Louisville, KY are expected to open Friday February 21st. More details will follow soon.  Check the Spring 2025 meeting webpage for further information.

C37D – Submarine Cables Fall 2024


C37D – Submarine Cables, meeting Monday, October 21, 2024 from 3:30 – 5:30 PM, will include the following presentation:

Challenge of TDR and Murray Bridge Fingerprint on world’s longest HVDC cable, by Manfred Bawart, BAUR GmbH

The presentation highlights the application of TDR fingerprints on the Viking Link, which spans an impressive 761 km. This marks the first time TDR has been employed on such an exceptional cable length. A comprehensive analysis of the joint positions once again revealed non- linear pulse propagation, which could significantly impact the accuracy of distance measurements for fault location.

To address this challenge and enhance the preparedness plan, numerous cable joints were measured along the entire length of the cable, enabling the individual assessment of pulse propagation characteristics. As a result, future fault locations can be identified with greater precision using TDR.

Also for the first time, a Murray Bridge fingerprint has been created for the Viking Link. This case study highlights the potential of utilizing Murray Bridge techniques to measure both low and high resistance cable faults over this extensive cable length. The results from the measurements were fast and with impressive measuring accuracy. The integration of the Murray Bridge technique complements the TDR test, providing a means to validate measurement results through an alternative method in the event of a cable fault.


C39D – Seismic Performance Assessment of Transmission Cables – Fall 2024

C39D, meeting Wednesday, October 23, 2024 from 8-10 AM, will include the following presentation:

Seismic Design for Underground Transmission System

Wei Zheng, Kiewit, USA

Abstract: Seismic design of underground transmission systems is critical for ensuring the resilience and reliability of essential infrastructures during earthquake events. However, there are no well-established guidelines on seismic design of underground transmission systems. This presentation will describe the seismic design of entire electrical power system and identify major seismic hazards and design challenges for the underground transmission systems. Underground cable performance during the Christchurch Earthquakes will be reviewed to identify key considerations in seismic design. Seismic design guidelines for water pipelines will be reviewed to explore how design earthquake is determined based on water pipeline function classes and levels of redundancy. Finally, a design process is recommended for a safe and resilient seismic design of underground transmission system.

October 14 Update for Fall 2024 ICC Meeting:

!!! ICC HOTEL POWER HAS BEEN RESTORED !!!

I’ve received confirmation from the ICC hotel that power was restored late last night and as of this morning, all hotel systems are operating normally.  The ICC will be meeting in Bonita Springs as planned.

For nearby restaurants, shopping, attractions, etc., I’m told that the ICC hotel was last to be restored so I would expect these venues to be open unless prevented by storm damage; however, I recommend calling to confirm.  

The two overflow hotels (Hyatt Place and TownPlace by Marriot) are also open but I would still confirm that you have a reservation.

I’m looking forward to seeing you soon in Bonita Springs.
