Have you ever wondered what’s underwater or who takes the pictures of all the sea animals and broken ships well it's these machines that are called ROVs which stands for Remotely Operated Vehicles.These underwater vehicles have been around for a long time.These vehicles also discovered most of the shipwrecks like the Titanic the ROVs have been sent by scientist to find and discover things like shipwrecks and other artifacts.This is why I think ROVs are valuable.They can see lost treasure that we cannot they can discover more and they can also last longer underwater. The First reason why ROVs are valuable is that ROVs can last longer underwater like what if some people went down into the sea in the oxygen has a hole in it they has to come up
used by the boat was essential for communication and the safety of its passengers. The Titanic,
Throughout the years submarine technology has advanced throughout the years from the original military submarine the turtle to the German u boats during WWII modern nuclear power submarines that we have today. These developments have required a lot of technological improvements. To make the u boats work the Germans need better battery and electrical motor technologies and the nuclear submarine obviously needed nuclear technology. Submarines have always been an innovative way to win the navel war.
Personal Watercrafts or "jet skis" are basically Personal Watercraft (PWC) are basically small inboard boats able to travel at high speeds due to large amounts of power and very light weight. Alomst all PWC's are under 600 lbs and most of todays PWC's have at least 90 hp.Not only are PWC's some of the fastest water vehicles they are also some of the most maneuverable water vehicles. This is because PWC's propultion is based on a jet that also is it's turning mechanism. When the driver turns the handlebars the jet (via cables) turns in the direction of the handlebars so the stern is pushed in the opposite direction. This allows the driver to turn at a much tighter angle than traditional boats with keels and rudders.The main drawback to this maneuverability is the fact that if there is no thrust coming from the engine the ability to turn is effictively zero meaning that anytime the driver presses the kill switch (a large red button) they lose all ability to steer. This is extremely dangerous whenever an inexperienced person may drive the PWC back to dock or into shore. PWC's have no brakes and have no ablilty to stop other than turning around. They have an extremely efficient ability to hydroplane (when most of the PWC is above water) and it takes most PWC's a few hundred feet to come to a stop after being at full throttle. This is because 600 lbs + a rider is traveling at a very high speed with only minimal friction to slow them down (since PWC's are made to travel with very little friction).

The titanic was a ship that was huge and extremely advanced. The ship took 3 years to be completed and over 3, 000 people worked on it. Although the final product could not be fully used it was a well built ship. This ship was well equipped with the best and
“A ship in the harbor is safe, but that is not what ships are built for.” A wise quote from John A. Shedd. A boat is secure inside the harbor, but it is useless. Inside a harbor, a boat can’t traverse oceans, set wars in motion, or discover new lands. Figuratively, we, the people, are the ships, and our safe haven is our comfort zone. Without reaching out of your comfort zone, you can’t conquer your world. You can’t make a difference. You need take a risk. Leave your safe haven and explore.
The tragic history of the Titanic, the sinking of the “unsinkable” giant of a ship shocked the entire world and contributed to important shifts in the mass consciousness of the people who lived at that period and assessed the achievements of new technologies and their role. However, one would have been hardly able to predict in 1912 that this tragedy, no matter how significant and meaningful, would leave such a deep imprint on the history of human civilization. The continuing interest in the fate of the great vessel has taken the form of various narrations and given rise to numerous myths enveloping the true history and, in this way, often obscuring the facts related to the tragedy. In recent years, this interest has been emphasized by the dramatic discovery of the wreck and examination of its remains. The recovery of artifacts from the Titanic and the exploration of the site where it had sank stimulated new speculations on different issues of the failure to rescue the Titanic and the role of different factors contributing to the disaster. These issues have been traditionally in the focus of discussions that caused controversies and ambiguous interpretations of various facts. They also often overshadowed other parts of the disaster story that were confirmed by statistical data and revealed the impact of social realities. The social stratification of passengers that reflected the social realities of the period and its class interests determined the chances of survival, with most of those perished in the Titanic disaster having been lower class individuals.
Archaeology is a continuously evolving field where there is a constant stream of new branches and excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor. Underwater archaeology’s role has increased in recent years as it allows archaeologists to more accurately interpret the past by supplementing information gained through traditional land excavations.
Several military robotic automation systems already operate at the level where the human is still in charge and responsible for the deployment of lethal force, but not in a directly supervisory manner. The Phalanx system for Aegis-class cruisers in the Navy is designed to be the last line of defense against anti-ship missiles. The gun mount moves with rapid precision. The system takes a low amount of input from the ship, making it capable of functioning despite potential damage to the ship. There are several settings for the Phalanx system, with the final fail safe setting of “casualty” that will defend the ship from air attacks without human selection of targets. The MK 69 encapsulated torpedo (CAPTOR) sea mine system was the U.S. Navy's standard anti-submarine mine during the Cold War, having enough computer power t...

More than forty thousand merchant ships, and countless number of smaller coastal craft, ply world oceans which comprise nearly seventy percent of the earth’s surface. Each year approximately ten million containers of cargo, containing raw materials to finished goods are transported by seas. The ships are owned by different states, private companies or individuals and manned by mixture of seafarers from different countries, mixed together from various nationalities. These ships are perhaps the most autonomous entities on earth as rule of law allows frequent change of their allegiance or identity by choosing a flag to suit their requirement.
Salvage and Towage are two concepts widely known in the maritime world, nowadays offering employment to many specialized professionals.
But it is also a fact that this century is also trying to use this UAV technology in a different perspective, away from war or destruction and is hoping to create a new series of real achievements by deploying it. Especially, it goes true for Business sector which can add quality service badge on its shoulder by using it in a way more productive, economic and fruitful for mutual benefits.
