Andy Jefferies is the founder and principal owner of Deep Sea Development Services Inc. (DSDS) and a co-Founder of Integrity Management & Response (IMR). DSDS, founded in 1996, is a Subsea Engineering company focused on field development and subsea operations support. Prior to founding DSDS, Andy was the Engineering Manager at H.O. Mohr Research and Engineering (HOMRE). Prior to HOMRE, Andy worked in various roles at McEvoy Oilfield Ltd. in the UK and US.
Andy’s first subsea project was the Shell Esso Cormorant field in the UK sector, specifically involved in the insert valve development of part of the Underwater Manifold Center (UMC). The UMC was installed and operated in a water depth of approximately 450’. The UMC was an extension of the Exxon SPS project which was a pioneer in the development of subsea technology in the late 70’s.
By contrast, Andy was part of the ground breaking Beacon Shenandoah development which required the development of new technologies to accommodate mudline shut-in pressures in excess of 15,000 psi in a water depth of 6,000 ft.
Over the past 40+ years in the industry, Andy has worked in the development of fluid swivel technologies for FPSOs, fatigue testing of premium threads for sour service, perforating gun shaped charge performance evaluation, reeled SCR design well containment program development and support, as well as multiple key field development efforts. Some of these key projects include:
-
Matterhorn – subsea infrastructure and TLP
-
Independence Hub – subsea infrastructure and FPS
-
Thunder Hawk – subsea infrastructure and FPS
-
Medusa – subsea infrastructure and SPAR
-
Galapagos (Santiago/Santa Cruz) – subsea infrastructure and FPS upgrade
-
Shenandoah – subsea infrastructure and FPS
-
Winterfell - subsea infrastructure tied back to an existing SPAR
In 2010, DSDS was involved in the BP response to the Macondo incident. Following that exposure, DSDS was involved with a number of independent operators in the formation of the Helix Well Containment Group (HWCG). Andy was part of the team that developed the HWCG well containment plan which resulted in the first post moratorium BOMRE drilling permit approval. For the next 9 years, Andy expanded DSDS’s role in well containment support to the industry, culminating in the formation of IMR in conjunction with J. Connor Consulting, Inc. (JCC). IMR now supports 17 operators domestically across both established response equipment programs (MWCC and HWCG) and supports many of these operators internationally with their OSRL based organization programs. This support is in the form of up to 35 trained responders as well as the 24/7/365 availability of the IMR Emergency Operations Center (EOC).
