Leadvent Group brings the subsea power industry together to address cable reliability, installation challenges, interconnection development and the future of offshore energy infrastructure.
LONDON, UNITED KINGDOM | 28 October 2026 — As offshore renewable energy projects expand and cross-border electricity connections become increasingly important, reliable submarine power cable infrastructure remains essential to the development of resilient energy networks. Against this backdrop, Leadvent Group announces the return of the 6th Annual Submarine Power Cable and Interconnection Forum, taking place on 18–19 November 2026 at the Radisson Blu Hotel, London Heathrow, London, United Kingdom.
The two-day event will bring together professionals from across the submarine cable and interconnection sectors to examine the technical, operational and commercial challenges shaping subsea power transmission. Discussions will focus on cable design and technology, installation procedures, route engineering, fault detection, cable protection, asset management and strategies for improving reliability while managing project costs and risks.
As the energy transition continues to drive investment in offshore wind, high-voltage direct current (HVDC) transmission and international electricity interconnectors, the industry faces growing demands for dependable infrastructure, effective maintenance strategies and long-term asset performance. The forum will provide a platform for industry stakeholders to exchange technical knowledge, examine practical approaches and explore developments influencing the future of submarine power cable systems.
Building on the Success of the Previous Edition
The 6th Annual Submarine Power Cable and Interconnection Forum builds on the previous edition, held in London, United Kingdom, in 2025. The event attracted more than 140 industry professionals, providing opportunities for speakers, delegates, sponsors and exhibitors to connect, exchange perspectives and strengthen professional relationships across the submarine power cable sector.
The fifth edition reflected the importance of bringing together stakeholders working across cable engineering, offshore energy, installation, maintenance and interconnection development. The continued need to improve cable reliability, manage installation risks and protect critical subsea infrastructure makes industry collaboration particularly important as energy networks evolve.

Addressing the Challenges Shaping Submarine Power Cable Infrastructure
Submarine power cables are critical to connecting offshore renewable energy generation with onshore grids and enabling electricity exchange between countries. However, delivering and maintaining these systems involves complex engineering requirements, challenging marine environments and significant investment.
The 2026 forum will address important areas across the submarine cable lifecycle, including survey and route selection, cable design, manufacturing, installation, protection, inspection, fault detection and repair.
Particular attention will be given to the importance of reducing cable failures, improving asset integrity and identifying practical approaches to managing the risks associated with subsea infrastructure. As cable systems become increasingly important to offshore energy and international grid connectivity, effective monitoring, maintenance planning and protection measures remain central to operational reliability.
The event will also explore developments in HVDC transmission, digital monitoring, predictive maintenance and cable technologies supporting the expansion of offshore renewable energy projects and cross-border interconnections.
Connecting Industry Expertise and Practical Experience
The development of reliable submarine power cable infrastructure requires cooperation across the entire value chain. Utilities, transmission system operators, offshore wind developers, cable manufacturers, installation contractors, engineering specialists and service providers all contribute to the successful delivery and operation of subsea systems.
The forum will provide opportunities for participants to exchange experiences, discuss shared technical challenges and explore approaches to improving project delivery, operational performance and risk management.
Alongside technical discussions and presentations, the event will facilitate professional networking among stakeholders seeking to strengthen industry relationships, explore business opportunities and develop a clearer understanding of the challenges facing the submarine power cable sector.
By bringing together professionals with complementary expertise, the 6th Annual Submarine Power Cable and Interconnection Forum aims to support continued dialogue on the technologies, strategies and industry practices needed to develop dependable subsea power infrastructure.
