Chinese Oceanographic Research Ship Zhang Jian
Chinese oceanographic research ship ''Zhang Jian'' is a Chinese research ship designed by Shanghai Ocean University and built by the civilian-owned Zhejiang TianShi Shipbuilding Co., Ltd. (浙江天时造船有限公司) in Wenling, instead of government-owned enterprise, as in most cases of the ships in Chinese service. ''Zhang Jian'' is the newest research ship in China (as of 2015), and it is designed to have an endurance of 60 days before needing resupply. The ship is designed to be a multifunction ship capable of carrying out various missions that previously had to be performed by separate ships. The ship primarily functions as an oceanographic research ship, but it can also act as a dive tender, a salvage ship, a rescue ship, a tourist ship, and a mother ship for a deep-submergence vehicle. The ship will be used as a mother ship for a . The ship also carries other equipment for deep sea exploration, including an unmanned underwater vessel and three benthic landers. Design ...

Zhang Jian (politician)
Zhang Jian (; 1 July 1853– 24 August 1926), courtesy name Jizhi (季直), art name Se'an (啬庵), was a Chinese entrepreneur, politician and educator. He is known as a "new gentry" and official-entrepreneur. Biography Zhang was born in Haimen county, Jiangsu province in 1853. He initially served as a staff member under the general Wu Changqing. After Wu's death, he returned to his hometown where he studied agriculture while preparing for further examinations. In 1894, he achieved the highest score in the Palace Examination, earning the prestigious title of '' zhuangyuan''. Subsequently, he served at the Hanlin Academy. Zhang was obliged to return to his hometown for mourning his father in the same year. After the First Sino-Japanese War, he ventured into investing in and establishing modern enterprises. He later founded Dah Sun Cotton Mill in Nantong, financed by both the imperial court and local merchants. Additionally, he diversified into land reclamation, river conservanc ...

Mother Ship
A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft. Examples include bomber aircraft, bombers converted to carry experimental aircraft to altitudes where they can conduct their research (such as the B-52 carrying the X-15), or ships that carry small submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atlantis II carrying the DSV Alvin, ''Alvin''). A mother ship may also be used to recover smaller craft, or go its own way after releasing them. A smaller vessel serving or caring for ''larger'' craft is usually called a tender ship, tender. Maritime craft During World War II, the German Type XIV submarine or ''Milchkuh'' (Milk cow) was a type of large submarine used to resupply the U-boats. Mother ships can carry small submersibles and submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atla ...

Research Vessels Of China
Research is creativity, creative and scientific method, systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, Discovery (observation), discovery, interpretation (philosophy), interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemology, epistemologies, which vary considerably both within and between humanities ...

Benthic Lander
A benthic lander is an autonomous observational platform that sits on the seabed or benthic zone to record physical, chemical or biological activity. Benthic landers have deployment durations from a few days (for biological studies) to several years (for physical oceanography studies). In these studies they conduct a variety of underwater measurements, and thus different lander configurations exist to meet differing needs for different measurements. Purpose Samples that are brought up from the seabed undergo large changes in temperature and pressure, thus changing their physical and chemical composition and properties. This change in properties means that any measurements taken from samples brought to the surface do not provide accurate data. In order to avoid this, it is best that the measurements are taken directly at the seabed level, without moving the samples. Initially, to prevent altering samples, divers would go to the sea bed and carry out the experiments. However ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Underwater Vessel
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. It has been reported that the armed forces of more than 100 countries have approximately 170 different types of drones in service. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) **Self-driving truck **Driverless tractor * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft, either fixed-wing or rotorwing, commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium ...

Deep-submergence Vehicle
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs ( deep-submergence rescue vehicles), which are intended to be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions (primarily installing wiretaps on undersea communications cables), or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole. Strictly speaking, bathyscaphes are not submarines because they have minimal mobility and are built like a balloon, using a habitable spherical pressure vessel hung under a liquid hydrocarbon filled float drum. In a DSV/DSRV, the passenger compartment and the ballast tank functionality is incorporated into a single structure to afford more habitable space (up to 24 people in the case of a ...

Salvage Ship
A salvage tug, also known historically as a wrecking tug, is a specialized type of tugboat that is used to rescue ships that are in distress or in danger of sinking, or to salvage ships that have already sunk or run aground. Overview Few tugboats have ever been truly fully dedicated to salvage work; most of the time, salvage tugs operate towing barges, platforms, ships, or performing other utility tugboat work. Tugs fitted out for salvage are found in small numbers around the globe, with higher concentrations near areas with both heavy shipping traffic and hazardous weather conditions. Salvage tugs are used by specialized crew experienced in salvage operations (salvors). Their particular equipment includes: * extensive towing provisions and extra tow lines/cables, with provisions for towing from both bow and stern and at irregular angles * extra cranes * firefighting gear ** deluge systems ** hoses ** nozzles * mechanical equipment such as: ** common mechanical repair parts ** ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first transatlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dive Tender
A diving support vessel is a ship that is used as a floating base for professional diving projects. Basic requirements are the ability to keep station accurately and reliably throughout a diving operation, often in close proximity to drilling or production platforms, for positioning to degrade slowly enough in deteriorating conditions to recover divers without excessive risk, and to carry the necessary support equipment for the mode of diving to be used. Recent offshore diving support vessels tend to be dynamically positioned (DP) and double as remotely operated underwater vehicle (ROV) support vessels, and also be capable of supporting seismic survey operations and cable-laying operations. DP makes a wider range of operations possible, but the platform presents some inherent hazards, particularly the thrusters, making launch and recovery by diving bell widespread. They may use a moonpool to shelter the position where the bell or ROV enters and exits the water, and the launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State-owned Enterprise
A state-owned enterprise (SOE) is a business entity created or owned by a national or local government, either through an executive order or legislation. SOEs aim to generate profit for the government, prevent private sector monopolies, provide goods at lower prices, implement government policies, or serve remote areas where private businesses are scarce. The government typically holds full or majority ownership and oversees operations. SOEs have a distinct legal structure, with financial and developmental goals, like making services more accessible while earning profit (such as a state railway). They can be considered as government-affiliated entities designed to meet commercial and state capitalist objectives. Terminology The terminology around the term state-owned enterprise is murky. All three words in the term are challenged and subject to interpretation. First, it is debatable what the term "state" implies (e.g., it is unclear whether municipally owned corporations and ente ...
