The MANSLAGT Z1 Platform has been successfully removed from estuary mouth of the river Ems. Within the second project stage the topsides and the jacket have been decommissioned in two steps. The lifting, transport on the hook to shore and set-down on the quay of disposal yard have been performed by sheer-leg Barge “MATADOR 3”. Structural, in-place and rigging analyses for the platform as well as hydrostatic and mooring calculations for the crane barge have been conducted by Overdick.

The Manslagt Gas Production Platform was built in 1993. After platform shut down in 2009 the platform removal was decided in 2012.
The location of the platform in ecological protective area required special solutions for environmental protection.
