UXOcontrol completes final Hollandse Kust Zuid campaign

UXOcontrol has successfully completed a UXO identification and disposal campaign on the Hollandse Kust Zuid 3 & 4 wind farms for Vattenfall. This the final of two campaigns for the Hollandse Kust Zuid wind farm.

Vattenfall selected UXOcontrol as the contractor for two campaigns to clear the Hollandse Kust Zuid offshore wind farm area of UXO’s prior to installation of the windturbines and subsea cables. The first campaign, for Hollandse Kust Zuid 1 & 2, was completed in 2020.

The second campaign ran from early February 2021 until July 2021. The campaign commenced using the Noordhoek Pathfinder as the offshore ID vessel utilising a Triton XLX ROV equipment with a TSS 440 to enable detection of the UXO’s in the area and 6” ROV Dredge pump for uncovering the targets for identification, after a short break in the project the operations then were continued using the EDT Hercules and a Schilling HD ROV equipped with the TSS 440 and 6” ROV Dredge.

During the period of the campaign a total of 1350 targets were successfully investigated with a total of 19 targets being highlighted as UXO’s for neutralisation. During the project UXOcontrol worked closely with the Royal Dutch Navy to assist with uncovering and clearing the UXO’s so the Navy could then conduct the safe detonation of the UXO’s.

Hollandse kust Zuid

Hollandse Kust Zuid is a project of Vattenfall with recently BASF as co-owner. The wind farm was tendered in two rounds: Hollandse Kust Zuid 1 & 2 and Hollandse Kust Zuid 3 & 4. Vattenvall won both subsidy-free tender rounds in 2018 and 2019 respectively. In July 2021, offshore construction began. The wind farm is expected to be fully operational in 2023. It will then be the largest offshore wind farm in the world with 140 Siemens Gamesa 11 MW wind turbines and a total installed capacity of 1.5 Gigawatts. Source: UXOcontrol
