Underwater Construction Corporation (UCC), a provider of specialized underwater diving services, announced a strategic investment from Crescentia Capital, in partnership with Graham Capital Investments (GCI). The investment provides UCC with additional resources to accelerate organic growth, expand capabilities and geographic reach, invest in technology, and pursue strategic acquisitions.

The investment marks the next stage of growth for UCC while building on the leadership, people, and expertise that have defined the company for more than five decades. Raymond W. Palumbo will continue to serve as President and CEO, with UCC's experienced leadership team, project supervisors and divers continuing to lead the company's operations.
