Odyssey's efforts in the shipwreck business concentrate on the six major steps necessary for successful projects: research, project development, search, recovery, conservation, and marketing.

RESEARCH

The foundation of any shipwreck search and recovery expedition is research behind the project. Not only is the research necessary to evaluate the potential value, location and viability of finding a shipwreck, but it is also necessary to establish the historical significance and the archaeological requirements of the excavation.

Odyssey hires and maintains relationships with many of the top shipwreck researchers in the world in order to scout out any potentially viable projects. Data from these researchers is brought in and checked against Odyssey's own database and resources, compared with information from other experts, and then reviewed in exhaustive detail before further money is spent on the project.

PROJECT DEVELOPMENT

Even after the research has been assembled for any given shipwreck, the data is relatively useless without legal rights to the shipwreck and/or the actual aid and cooperation of the government that has jurisdiction over the shipwreck. In the case of shipwrecks that lie beyond any government's jurisdiction, how and where the artifacts or cargo from the shipwreck is brought ashore could determine whether the cargo may be claimed legally by the salvor.

It is critical to develop a working relationship with the government or company that holds the rights to a given shipwreck. Developing these relationships is often time-consuming and requires tremendous patience. Many foreign governments have had bad experiences with "treasure hunters" in the past, and are wary and skeptical of any mention of commercial salvage.

Odyssey's principals, employees and consultants have developed a great deal of credibility in the archaeological, political and historical community surrounding shipwrecks. In the past they have successfully diminished a government's concerns about their potential embarrassment by failed projects. Odyssey's agreement with the government of the United Kingdom is an example of official relationships that demonstrate the confidence placed in Odyssey's scientific, technical and professional expertise.

In some cases, other parties may have an interest or ownership claim in a shipwreck or cargo, such as an insurance company. Odyssey thoroughly researches potential claims and determines a strategy before large expenses for search and recovery are incurred. Odyssey's recent agreement with Atlantic Mutual Insurance allowed the company to obtain the full rights and title to the SS Republic shipwreck in a very short amount of time.

SEARCH

The search phase begins with a side-scan sonar survey of the target area. A sonar "fish" is pulled behind a research vessel, sending data back to shipboard computers. The fish has transducers on both the port and starboard sides. These transducers send out pulses of sound or "pings". After the ping is sent out, the fish listens for an echo. Hard objects reflect the sound back - metal is best, but rock, pottery and other relatively hard objects reflect well , and soft materials show up the least.

In some cases, a magnetometer is used in concert with the side scan sonar to identify areas with a high concentration of ferrous metals.

Every anomaly on the ocean floor is recorded, and then analyzed by Odyssey's specialists. The most promising anomalies (based on size, shape, location and other factors) are then considered targets.

The targets are then visually inspected using a remotely operated vehicle (ROV). Controlled from the research vessel, the ROV sends real time video images of the targets to the control room for analysis. In some instances an artifact will be recovered for further identification.

Based upon the need for confidentiality during the search phase of our projects and the reduced operating cost, Odyssey owns the 113' research vessel R/V Odyssey equipped with state of the art search and identification equipment. The R/V Odyssey is our primary search vessel and can recover small artifacts that aid in identifying our targets on a very cost-effective basis. This vessel operates with a ship's crew of 5 and a technical crew of 4. This vessel located the wreck of the SS Republic.

RECOVERY

Recovery operations combine high tech ROVs, robotics, cameras and specialized computer hardware and software to carefully record the location of artifacts in situ and throughout the recovery and conservation process. ROV pilots and archaeologists work in concert aboard the recovery vessel, directing robotic operations taking place hundreds and sometimes thousands of feet below.

Work generally begins with an archaeological pre-disturbance survey which includes a detailed photomosaic of the site. Once complete, the archaeological excavation and recovery of artifacts can begin.

The Odyssey Explorer, a 251-foot Class II dynamically positioned (DP) ship and state-of-the-art deep ocean archaeological platform, is used for Odyssey's recovery work. The ZEUS remotely operated vehicle (ROV) is the centerpiece of Odyssey's advanced robotic archeology system. The 200HP vehicle is the size of an SUV and weighs 7 tons. ZEUS is rated to operate at depths to 2,500 meters (8,200 ft) and is driven by eight powerful hydraulic thrusters. The ROV has two Schilling seven - function Conan spatial correspondent manipulators which provide for exceptional dexterity and fine control required for delicate archaeological procedures.

The system's cameras feed high-resolution video signals through advanced fiber optic telemetry to the surface.

CONSERVATION AND DOCUMENTATION

Every item recovered from a shipwreck site must go through a conservation process. The goal of conservation is to stabilize the artifact. The conservation process may take weeks, months, or even years, depending on the artifact.

During conservation, the artifacts are also being studied. Photos, archaeologists' descriptions and other data are recorded and documented. Findings are then published and shared with the archaeological community.
