Underwater Engineering Services, Inc. (UESI)- formerly known as S.G. Pinney & Associates, Inc. (SGPAI) has provided engineering, inspection, testing and other related services to the power industry since 1977. Responsibilities have included material selection, preparation of specifications, corrosion surveys, nondestructive examination, QA/QC inspection activities, and other related services during both construction and operational phases at power facilities.

Recognizing the need for comprehensive maintenance services in nuclear power plant immersion areas, SGPAI formed the Underwater Engineering Services, Inc. group in 1984 to provide these and other services. Underwater Engineering Services, Inc. (UESI, then a wholly owned subsidiary of SGPAI) was incorporated in 1990. UESI pioneered numerous repair processes in the nuclear industry. Since the inception of our nuclear program, nuclear Safety Related services have been expanded to include underwater welding, as well as underwater demolition and installation of ECCS suction strainers, strain gauge sensors and other mechanical and instrumentation maintenance projects.

The scope of services provided by UESI quickly expanded in 1992 to fill a need for quality services to perform concrete rehabilitation at power production facilities. As the company employed new trades including carpenters, masons, and boat captains UESI developed a reputation for quality workmanship performing numerous tasks as a subcontractor completing restoration of marine structure and erosion control projects. Project owners have included Florida DOT, South Florida Water Management, U.S. Army Corps of Engineers, and Florida Power and Light. Restoration projects have included a wide variety of structures including bridges, water control structures, plant intakes, bulkheads, seawalls, piers, wharves, and small boat facilities. Erosion control projects have included installation of geotextile - filter fabrics, pump-in-place concrete revetments, pre-cast articulating mats and limestone riprap. With the numerous erosion control projects, in-house trades have been expanded to include equipment operators. Other projects have included traveling water screen rehabilitation, mud removal, trash rack installation, pipeline construction and repair, underwater welding and cutting, and removal of hazardous material. UESI has also quickly expanded its geographical range, performing many projects across the entire United States as well as in Japan, South Korea, Cuba, and the Dominican Republic.
In April of 1997, UESI stock was sold to Greenman Pedersen, Inc., a design/structural engineering firm headquartered in Babylon, New York (www.gpinet.com). GPI is ranked number 66 of the top 500 design firms as rated by Engineering News-Record for 2012. The acquisition has served to strengthen and expedite the UESI plan for growth and expansion. UESI has purchased the assets of United Marine, Inc. and Underwater Unlimited Diving Services, Inc.

In 1999 due to the growth of the erosion control projects and marine structure restoration projects, UESI obtained a specialty contracting license for Marine Contracting and began completing projects as a prime contractor. Project owners have included Florida DOT, South Florida Water Management, U.S. Army Corps of Engineers, Florida Power and Light and numerous city and county governments. In addition to marine structure restoration, some structures have been built including boardwalks and culverts. . In response to the growing amount of construction tasks and size of projects completed UESI obtained a state of Florida General Contractor license in 2004. UESI has completed bonded projects valued over $6,000,000.00 and our largest project was valued at $61,000,000.00. Construction Managers and the QA Manager have handled subcontractors and vendors for electrical, metal fabrication, instrumentation fabrication, marine plant – fully founded, environmental services, survey, sod installation and landscaping. In response to the growing amount of construction tasks and size of projects completed, UESI obtained a State of Florida General Contractor License in 2004.
