32-541: The ship was originally the FS A. v. Humboldt , and was in service for the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) until 2004. The vessel underwent a partial refit in 2021; which saw the vessel lengthened to 68 meters, the addition of a crane, additional cabins, and a mission control center. Hercules is the primary vehicle of a two-body remotely operated underwater vehicle (ROV) system. Hercules

64-420: A binnacle and voice tubes to allow the conning officer to direct the ship from a higher position during fair weather conditions. Larger warships may have a navigation bridge , which is used for the actual conning of the ship, and a separate admiral's bridge can be provided in flagships , where the admiral can exercise control over the squadron of ships without interfering with the captain's command of

96-407: A command deck ), or wheelhouse (also known as a pilothouse ), is a room or platform of a ship , submarine , airship , or spaceship from which the ship can be commanded. When a ship is under way, the bridge is manned by an officer of the watch aided usually by an able seaman acting as a lookout . During critical maneuvers the captain will be on the bridge, often supported by an officer of

128-488: A compass , a marine chronometer , two-way radios , and radiotelephone , etc. A flying bridge, also known as "monkey island", is an open area on top of a surface ship that provides unobstructed views of the fore, aft, and the sides of a vessel. It serves as an operating station for the ship's officers, such as the captain or officer of the watch . Prior to World War II, virtually every sailing ship , steamship , monitor , paddle steamer , or large pleasure ship had

160-523: A commercial vessel, the bridge will contain the equipment necessary to safely navigate a vessel on passage. Such equipment will vary with ship type, but generally includes a GPS navigation device , a Navtex receiver, an ECDIS or chart system, one or more radars , a communications system (including distress calling equipment), engine ( telegraph ) controls, a wheel/autopilot system, a magnetic compass (for redundancy and cross check capability) and light/sound signalling devices. The navigation station of

192-560: A fast profiling conductivity-temperature-depth ( CTD ) sensor, an oxygen probe, two high-resolution scanning sonars , a 1.2 MHz multibeam sonar and a high resolution stereo still camera system. The primary manipulator is an arm with force feedback, complemented by a seven-function manipulator for sample collection. Hercules is also equipped with a number of tools, including a suction sampler, sampling boxes with actuating trays, and sediment coring equipment, as well as several other purpose-built tools for different scientific objectives. Using

224-443: A flying bridge above the main bridge. Flying bridges were generally not enclosed at all (although sometimes they were partially enclosed), and often had little equipment—usually just a speaking tube or telephone to allow communication with the helmsman or wheelman on the main bridge. On military warships after 1914, the flying bridge was usually the station for the air defense officer and the gunnery officer. The amount of equipment on

256-454: A flying bridge varies widely with the need of the captain. During World War II, for example, American submarine chaser surface ships had a well-outfitted flying bridge which usually contained a pelorus , signal lamps, telescope , and voice tube to permit the captain to command the ship. U.S. Navy attack transport ships could be outfitted with either 20mm or 40mm automatic cannons on their flying bridges. Flying bridges were almost always

288-784: A geosynchronous satellite, and then down to a ground station in Andover, Maine. The ground station passes the signals to the Inner Space Center (ISC) at the University of Rhode Island Graduate School of Oceanography. From the ISC, the multicast video streams are distributed to the Internet and used in highlight reels and webcasts. During expeditions, Nautilus can send broadcast-quality video streams, associated intercom traffic and data back to shore in real time. All audio components of

320-408: A high-ranking officer such as an admiral could conduct fleet operations, plan strategy, and conduct large battles. Some flying bridges have "bridge wings", open areas which thrust outward from the flying bridge over the sides of the vessel by approximately 10 to 15 feet (3.0 to 4.6 m) to allow an officer to see the side of their ship while docking or working with smaller vessels. A bridge wing

352-407: A navigation system in tandem with ultra-short baseline positioning, Hercules is capable of maneuvering and hovering on a centimeter-scale grid. Argus is a deep-tow system capable of diving as deep as 6,000 meters (20,000 ft). Argus is typically used in tandem with Hercules, where it hovers several meters above the seafloor and provides a view of Hercules on the seafloor, but can also be used as

384-459: A ship may be located on the bridge or in a separate chart room, nearby. It includes a table sized for nautical charts where calculations of course and location are made. The navigator plots the course to be followed by the ship on these charts. Besides the desk and the navigation charts, the area contains navigational instruments that may include electronic equipment for a Global Positioning System receiver and chart display, fathometer ,

416-480: A standalone tow sled. The frame carries a broadcast quality high definition camera, standard definition cameras, and two 1,200 Watt arc lamps capable of producing over 100,000 lumens of light each. Argus also supports a wide range of instrumentation, including a depth sensor, altimeter, CTD, sub-bottom profiler, scanning sonar, and side-scan sonar. Argus uses dual 2- horsepower (1.5  kW ) electric thrusters for heading adjustment and limited lateral movement. Diana

448-546: A telephone number that is bridged into the shipboard intercom system. Leibniz Institute for Baltic Sea Research The Leibniz Institute for Baltic Sea Research ( German : Leibniz-Institut für Ostseeforschung Warnemünde , abbreviated IOW) is a research institution located in Warnemünde ( Rostock ), Germany . It is part of the Leibniz-Association , cooperates with the University of Rostock and

480-412: Is also equipped with a 2–7 kHz sub-bottom profiler that permits identification of sub-seafloor features. The EV Nautilus satellite system uses a very-small aperture terminal ( VSAT ) to enable two-way Internet connectivity between ship and shore. The maximum uplink capability is up to 46 Mbit/s, depending on the ship’s location and the satellite being used. The signal is sent from Nautilus to

512-476: Is limited by cable length to 600 meters (2,000 ft). Diana's transducers can also be installed on the Argus towsled, which greatly increases the maximum towing depth to 2,000 meters. Echo is a five-channel deep tow, side scan sonar system rated to 3,000 meters (9,800 ft) water depth. Echo's operating frequencies are 100 and 400 kHz, which cover a total swath width up to 1,000 meters (3,300 ft). Echo

544-442: Is one of two side-scan sonar systems on board Nautilus . It is used to create maps of the seafloor and to identify targets of interest that ROVs Hercules and Argus investigate in more detail. Diana is a side-scan sonar tow-fish that uses dual 300 and 600 kHz frequencies, with a range of approximately 200 meters on either side of the towfish. The Diana system is capable of being towed to a depth of 2,000 meters (6,600 ft) but

576-463: Is rated to a depth of 4,000 meters (13,000 ft), and is always deployed with Argus. It is equipped with cameras, lights, instruments, manipulators, and a wide array of sampling tools. The primary camera is a high definition system augmented by six standard-definition cameras. Four lights (over 60,000 lumens total) illuminate the forward working area, while smaller incandescent lights provide auxiliary illumination. Standard instrumentation includes

608-422: The pilot , who was traditionally the ship's navigating officer, could issue commands from shelter. Iron , and later steel , ships also required a compass platform . This was usually a tower, where a magnetic compass could be sited far away as possible from the ferrous interference of the hulk of the ship. Many ships still have a flying bridge , a platform atop the pilot house, open to weather, containing

640-406: The rudder ). A wheelhouse was a small enclosure around the ship's wheel on the quarterdeck of sailing ships . On modern ships the wheelhouse or pilothouse refers to the bridge of smaller motor vessels, such as tugs . With the arrival of paddle steamers , engineers required a platform from which they could inspect the paddle wheels and where the captain 's view would not be obstructed by

704-412: The full range of controls of the pilot house. On larger small vessels, the flying bridge may actually be enclosed, in which case it is more properly called an "upper pilot house" or "upper bridge". Warships that were also flagships (had a flag officer onboard) sometimes contained a flag bridge . Also known as the "admiral's bridge", these were a bridge below the main bridge on a command warship where

736-463: The function of the vessels while at the surface. Modern advances in remote control equipment have seen progressive transfer of the actual control of the ship to the bridge. The wheel and throttles can be operated directly from the bridge, controlling often-unmanned machinery spaces. Aboard modern warships, navigational command comes from the bridge, whereas electronically directed weapon systems are usually controlled from an interior compartment. On

768-413: The highest bridge on the ship. They were usually above the flag bridge. Since the 1980s, large pleasure craft may have a flying bridge toward the stern that is used as additional outdoor seating space and a place to store a tender . On the smallest surface vessels, such as a sport fishing boat , the flying bridge may have controls permitting the ship to be piloted from the flying bridge, but will lack

800-547: The institute is fundamental research but also teaching at the universities of Rostock and Greifswald . IOW has direct access to the research vessel Maria S. Merian and can access by request a variety of other medium-sized vessels for longer trips and interdisciplinary tasks from the German research fleet. The institute's facilities are financed by the German Federal Ministry of Education and Research , and

832-434: The intercom audio to be heard in the live video streams on shore and in the recorded video clips. A studio was built on board Nautilus to support live interactions and outreach production. Educators and scientists conduct interactive interviews with partners located at schools, museums, aquariums, and science centers around the world. Shore-based groups are able to communicate with the ship either with an intercom unit or via

864-399: The paddle houses. A raised walkway, literally a bridge, connecting the paddle houses was therefore provided. When the screw propeller superseded the paddle wheel, the term bridge survived. Traditionally, commands would be passed from the senior officer on the bridge to stations dispersed throughout the ship, where physical control of the ship was exercised, as technology did not exist for

896-496: The remote control of steering or machinery. Helm orders would be passed to an enclosed wheel house, where the coxswain or helmsman operated the ship's wheel . Engine commands would be relayed to the engine officer in the engine room by an engine order telegraph that displayed the captain's orders on a dial. The engine officer would ensure that the correct combination of steam pressure and engine revolutions were applied. Weatherproof pilot houses supplanted open bridges so that

928-471: The telepresence network use a centralized intercom system for managing shipboard and ship-to-shore communications. This network provides communication between users working in the control van, the ship's officers on the bridge , and the various labs around the ship, as well as participants on shore. The intercom system is integrated with the Nautilus video streaming and video recording subsystems, which allow

960-426: The vessel. In older warships, a heavily armored conning tower was often provided, where the vital command staff could be located under protection to ensure that the ship could be commanded under fire. On a submarine, the bridge is the highest point on the conning tower , to provide for better visual navigation when on the surface. They became standard on United States Navy submarines after 1917, greatly improving

992-399: The watch, an able seaman on the wheel and sometimes a pilot , if required. There are many terms for parts of a ship with functions similar to a bridge. Depending upon the design and layout of a ship, some of these terms may be interchangeable. Traditionally, sailing ships were commanded from the quarterdeck , aft of the mainmast , where the ship's wheel was located (as it was close to
