FPSO Case Study

Swivel Module Handling Frame

Bespoke solution fitting into FPSO schedule


A North Sea operator required a new solution for handling both existing and replacement swivel modules, as the default transportation solution using a packing crate within a container was too heavy for the FPSOs cranes to handle.

MDL Solution

To minimise costs associated with POB, MDL performed a "desktop" review and concept development to understand the client's requirements, prepare an execution plan and story boards. Next, MDL in-house team design engineered a bespoke mechanical handling device, as well as additional units: a handling frame for storage of existing swivel once removed and a crane hook block cradle interface. This was followed by complete in-house manufacture of all units.


MDL also delivered a complete work pack and job cards for the swivel stack project, which included deck layouts, logistics storyboards and offshore planning, structural assessment of deck loadings and swivel module cleaning support frame. MDL's fit-for-purpose solution, delivered on time and to budget, allowed the client to perform the swivel replacement ahead of schedule.
