Jun 2018System TestingStale
Within the same "Offshore Cable Repair Vessel and Universal Joint" project for which TC Ormonde OFTO Limited is the funding licensee, successful high-voltage testing of universal joint test articles to specified standards, followed by a sea trial of the joint, is planned to be completed by June 2018. These tests are intended to qualify a universal repair joint for offshore transmission cables that can be used by Ormonde OFTO and other network licensees.
~May 2017Cable Repair
In summer 2017 Transmission Capital, on behalf of TC Ormonde OFTO Ltd, carried out export cable repair works on the Ormonde OFTO transmission link using the cable repair vessel STEMAT 82, with associated Notices to Mariners describing active repair and diving operations around the export cable corridor off the Ormonde offshore wind farm.
Sept 2017Construction OtherStale
As part of the Ofgem-funded "Offshore Cable Repair Vessel and Universal Joint" innovation project led by TC Ormonde OFTO Limited, the project plan requires that modifications to the vessel Wave Sentinel needed for offshore power cable repairs are completed by September 2017. These vessel modifications are intended to enable an industry-wide offshore cable repair capability accessible to OFTOs and transmission owners, including Ormonde OFTO.
20 Dec 2016Regulatory Other
Authority: Ofgem · Licence: Requirement to submit application on continuation of NIC Offshore Cable Repair Vessel and Universal Joint project
Following completion of the initial feasibility phase of the Offshore Cable Repair Vessel and Universal Joint NIC project, TC Ormonde OFTO Ltd submitted its recommendation to Ofgem on 20 December 2016 on whether to proceed to the construction phase, satisfying the Project Direction condition to apply by 31 December 2016.
19 Dec 2014Capital Support Awarded
On 19 December 2014, Ofgem issued a Project Direction to TC Ormonde OFTO Limited confirming that the "Offshore Cable Repair Vessel and Universal Joint" innovation project had been selected for funding under the Electricity Network Innovation Competition. Ofgem approved an NIC funding amount of £9,016,330 towards a total project budget of £10,329,000, with TC Ormonde required to provide a Network Licensee Compulsory Contribution of £1,032,900 and to deliver the project, including vessel modification and universal joint development, by 31 July 2018.
25 Jul 2014Capital Support Applied
On 25 July 2014, TC Ormonde OFTO Limited submitted the "Offshore Cable Repair Vessel and Universal Joint" project to Ofgem for consideration under the Electricity Network Innovation Competition (NIC). The application sought NIC funding to support development of a dedicated offshore cable repair vessel and a universal high‑voltage cable joint, with TC Ormonde acting as the Funding Licensee.
13 Sept 2013Inspection Survey
On 13 September 2013, a post-construction survey of the Ormonde offshore wind farm infrastructure, including the export cable route and route position list (RPL), offshore substation, inter-array cables and turbine locations, was reported. Commissioned by Vattenfall, the survey by EGS used a detailed line plan based on the provided infrastructure and export cable RPL to acquire bathymetric and side-scan sonar data, producing turbine-area charts, export cable alignment and difference plots (comparing 2013 data with a 2008 survey), and an overall bathymetric and seabed-features overview of the site and export cable route. These works served as an operational integrity and condition survey of the Ormonde transmission assets and associated seabed.
Jun 2013Geophysical Survey Complete
In June 2013, Vattenfall Wind Power Ltd commissioned EGS (International) Ltd to carry out a detailed post‑construction hydrographic and geophysical survey of the Ormonde offshore wind farm site, including the 30 wind turbine generators, the offshore substation and the single export cable route in the NE Irish Sea. Using the survey vessel Otarie equipped with multibeam echo sounder, side‑scan sonar, magnetometer and precise positioning, EGS ran approximately 341 km of survey lines to assess bathymetry, seabed morphology, cable burial and potential scour along the export and inter‑array cables in order to meet Marine Licence monitoring requirements.
Jul 2012Stake Transaction
In July 2012, International Public Partnerships (INPP), through TC Ormonde OFTO Limited, reached financial close on the long‑term ownership and operation of the Ormonde offshore transmission link, marking the start of its 20‑year regulated revenue term as the Offshore Transmission Owner connecting the 150 MW Ormonde offshore wind farm to the UK grid and enabling transmission of green electricity for around 100,000 homes.
12 Jul 2012Maintenance Other
Transmission Capital Partners, the Offshore Transmission Operator for the Ormonde transmission link, contracted Global Marine Systems Energy Ltd under a long-term cable maintenance agreement to provide subsea power cable repair, maintenance, and related engineering services for the Ormonde OFTO assets. The framework covers repairs, surveys, and re-burial activities, designates Global Marine as preferred subsea cable repair contractor with a 24/7 call-out facility, establishes agreed incident-response procedures, and includes creation and management of a site-specific cable system database for the transmission link.
