Horizon Announces Progress on WZ12-8E Development, China

The standalone self-installing platform (HYSY163) which was fabricated in Qingdao, China was substantially completed. Harbour and jack-up trials of the platform were then finalised prior to towing of the platform to the Beibu Gulf.

During the tow, heavy seas were encountered which led to water damage to some of the platform’s systems. As a precaution, the platform was towed ashore for further inspection and assessment. The inspections have identified the need to replace some of the waterdamaged mechanical and electrical components, such that the platform is expected to remain onshore until December 2021. In order to reduce the impact of the repairs on the schedule, remaining platform fit-out and commissioning works will also continue whilst the platform is ashore.

Since the platform is leased and the drilling rig is not on contract, none of the repair costs are expected to be borne by the joint venture. Therefore, development costs continue to be within budget.

Current expectations are that the platform will be installed in the field during December 2021, ahead of development drilling. Whilst first oil is targeted for 31 March 2022, due to the additional repair work this may be delayed by a few weeks to the first half of Q2 CY2022.

The laying of the 8km subsea pipeline, connecting the platform to the existing WZ12-8W wellhead platform, is largely complete (photo below), with hook-up operations commencing once the platform is at location. Cable laying operations are due to commence shortly.
