Apollo Completed Decommissioning Job with Success

Operating in its Element

Back to Overview

In January 2019 Apollo successfully completed its third job: decommissioning of the Halfweg Platform in the North Sea. The Halfweg platform is a three-well unmanned gas production facility in the North Sea, installed in 1995. The 500-tonnes topside of the Halfweg gas platform, including the four foundation legs, has been removed in between stormy weather and brought to shore for recycling.

The project is illustrative of the growing market for dismantling in the North Sea. In the Dutch sector alone, 77 of the 150 remaining platforms must be removed by 2025. The Uljanik Shipyard delivered the Apollo to DEME subsidiary, DEME Offshore, in mid-August 2018. The Apollo is a GustoMSC NG-5500X self-propelled jack-up design capable of undertaking autonomous transit and positioning offshore. The jack-up is equipped with well-balanced DP2 capability and VSD driven jacking system. Its 106.8m legs allow it to operate in a secure and fast way in water depths of up to 70 meters.

It is great to see all our ideas now put into practice, and work with so many great people who are all very excited about this ground-breaking project. Malte Roeder, Foundation Installation Manager Vattenfall

Approximately one year later, the wind farm became fully operational.

The Apollo was designed as a green vessel with solar panels and wind turbines on board, use of biodegradable grease and oil and heat recuperation, in order to operate it with the lowest possible fuel consumption while also keeping CO2, NOx, and SOx exhaust to the minimum. Take a look at the design page of the NG-5500X.
