FSO Case Study

CTU Hydraulic Control System

Fast-track delivery for African FSO


An offshore contractor required a Clevis Tensioning Unit (CTU) for their FSO offshore Cameroon. Thanks to our expertise in hydraulic tensioners, MDL was engaged to provide the hydraulic control system for the CTU.

MDL Solution

Following a "desktop" review, we design engineered the system, integrating into an existing MDL HPU, refurbished for this scope. We manufactured and integrated all the control system components and pipework, followed by performing pressure testing and flushing. We then carried out function testing of the CTU offsite, using the MDL HPU.


This was a fast-track project, with the hydraulic control system being designed and manufactured within a six-week timescale. Following the onshore works, an MDL Offshore Supervisor supported the integration of the CTU on the FSO and operated the HPU offshore Cameroon.
