Deep Ocean Search

Deep Ocean Search, a deep water survey and salvage company, provides worldwide subsea solutions across shallow, deep, and ultra-deep water environments. It operates from the surface to full ocean depths, with work reaching as deep as 11,000 meters for survey, positioning, salvage, and related offshore support. Its activities cover a broad range of underwater operations, including nearshore industrial work, remote under-ice expeditions, deep trench exploration, and complex missions for research, industry, government, and defense-related clients. The company works around the clock and worldwide, using a combination of adapted survey vessels, robotic systems, and experienced offshore personnel to carry out technically demanding work in difficult environments. Survey forms a major part of the business, covering seabed and hydrographic-style data collection with autonomous underwater vehicles, side-scan sonar, multi-beam echo sounders, magnetometers, photogrammetry, and high-resolution imagery. Those survey capabilities support exploration, research, operations, and special projects in both shallow and ultra-deep water. Positioning forms another core activity, where the company offers high-precision subsea positioning and metrology using USBL, LBL, INS, and imagery-based methods for tasks such as rig moves, spool metrology, and construction-related work. Deep Ocean Search carries out salvage operations ranging from lightweight recoveries to heavy-duty missions, covering recovery of structures, wrecks, planes, debris, sensors, cargo, submerged infrastructure, and vessel sections. Its work in this area extends from coastal waters to full-ocean-depth environments, and it supports clients needing recovery of valuable or critical assets from the seafloor. The company provides project management and client representation, along with strategic consulting, procurement support, and the drafting of specifications, scopes of work, and procedures. It handles broader subsea fleet management too, including maintenance, mobilization, inventory control, spare parts management, and skilled personnel provision. A distinctive element of the business, the Mariner XL, a 6,000-meter work-class ROV, forms part of its equipment and capabilities. Overall, the company concentrates on highly specialized deep-sea operations for scientific, maritime, industrial, defense, and offshore energy markets.
