Apollo Completed Decommissioning Job with Success

A storytelling platform about our offshore challenges
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.

Unlocking the full potential of offshore units
There is a tendency to design ever larger jack-ups enabling the installation the ever lager offshore wind turbines. This makes stability and using accurate wind loads prediction even more important. Testing this with a scale model in the early design stage is expensive and time-consuming. Also, separate parts of the jack-up such as the legs, cranes and deck load cannot be accurately tested at model scale because of large scale effects involved. With GustoMSC’s CFD calculation method, it is also possible to calculate the wind loads acting on the components of the jack-up separately for wind loads even at full scale.
Less costs and more efficiency with the CFD method
By accurately predicting the wind loads on jack-ups and its components with the CFD method, the jack-up can be optimized at the beginning of the design phase. This not only results in significant cost savings, but also increases the efficiency of jack-ups. By using the CFD method in the design phase, more space can be created on the deck of the jack-up, allowing more cargo to be transported. In addition, a lighter jack-up also offers an advantage during transport from port to the offshore work location. A lighter jack up consumes less fuel and that results in a smaller industry footprint.
The main advantage of using CFD is that it can provide useful information at the start of the design process.

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.In February 2020, it was one year ago that Bold Tern left the port of Hull in the United Kingdom with the first load of turbines for the world’s largest offshore wind farm installed to date: Hornsea One. 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.
