About

The Houlder name has been associated with the marine industry since the 1850s when it was formed as The Houlder Brothers’ Shipping Line. Houlder entered the Oil & Gas sector in the 1970s as a drilling and subsea contractor - designing, owning and operating mobile drilling units, dive support vessels and semi-submersibles including the Uncle John, currently operating in the Gulf of Mexico.

Today, the company provides wholly independent design & analysis, engineering & innovation and project management services varying from leading semisubmersible rig upgrades and vessel conversions to supplying new deck equipment and handling systems.
