As part of the Dual Gradient Drilling retrofit of a new Ultra Deepwater Drillship operating for Chevron on the US Gulf of Mexico, a dedicated tower was required for access, maintenance and testing of the Mud Lift Pump (MLP). Hampco designed, supplied and supervised the installation of the modular system which also incorporated handling aids and all the test piping to interface between rig systems and the MLP. This part of the overall project also included the development of a unique elevating and alignment system for the large test flange under the MLP.
