Allseas Engineering – Making Single Lift Possible
Presenter: Michael Jeffrey – Lead Heavy Lift Engineer Ninian Northern Platform topsides removal
Allseas is known for her flagship vessel the Pioneering Spirit and her single lift technology, the Topsides Lift System (TLS).

The main focus areas will be:
- The challenges dealing with aging offshore assets
- Completing preparations amid competing plug & abandonment activities
- Creative solutions for separating and lifting separating topsides from their jackets
- Executing a single lift
- Transferring an asset onshore with a transport barge and heavy lift skidding system
