The first rock placement campaign is expected to commence on 15 September the earliest, with works planned to be completed by 5 November.

Rock placement vessel Heimdal R will be carrying out the activities, while coaster vessels Hagland Carrier and Hagland Boss will transport rock from Norway to Sinclair’s Bay to complete the ship-to-ship transfer of rock to Heimdal R.

The start and end dates are subject to weather and operational uncertainties that could extend the overall duration to 19 November, with the potential for further extension to the work duration.
