First introduced in 1998, the HDU was developed by Deep Down as an alternative to industry-accepted vertical drive units to specifically enable substantially quicker, safer and more cost-effective installations of steel flying leads and specialty cables. The HDU eliminates the undesirable, and potentially hazardous, uneven tension experienced by steel flying leads and specialty cables during deployment and retrieval operations, as well as spooling, with vertical drive units.

Ron Smith, Deep Down CEO, said, "Our Horizontal Drive Units have made a significant contribution on subsea projects throughout the Gulf of Mexico. Installation contractors expend large amounts of capital to outfit their vessels with dedicated, high-tension deployment and recovery equipment required to put major systems in deep water. Ease of deployment, floor-space and safety are key considerations for these contactors. Our proprietary RDCs, SDBs and carousels can each be independently attached to the HDU. These additional components, including the HDU, can be stacked, thereby, saving valuable deck space on installation vessels.
"All these benefits combine to make our HDU, and its complementary, detachable RDCs, SDBs and carousels very attractive to our customers."
