“Dynamic positioning (DP) is a computer-controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors, and gyrocompasses, provide information. To the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position. Examples of vessel types that employ DP include ships and semi-submersible mobile offshore drilling units (MODU), oceanographic research vessels, cable layer ships, and cruise ships.” (Wikipedia, Dynamic positioning)
The nuclear system can be based on small modular reactors (SMR)
Nuclear-powered ships are also coming. Into the hands of commercial operators. The nuclear-powered ships are effective tools. Their operational range is virtually unlimited. And those ships can travel far away from places. Like Somalian coast, where pirates cause very big troubles. These pirates pose a great threat. The nuclear-powered ships. Can use new types of reactors that use molten salt moderator. The new small-sized portable reactors can give energy to the large-sized ships. The nuclear-powered ships can have dual-purpose roles. The DP technology is an interesting tool that can be integrated with the lighter aboard ship (LASH). That makes it possible to drive smaller ships on board smoothly and effectively.
Those dual-purpose ships can offer. An electric supply to the coastal cities. And maybe. Those ships can also. Make it possible to advance the hydrogen-powered aircraft and other hydrogen technologies. The hydrogen-powered aircraft can operate without limits. If they can get hydrogen from somewhere. Nuclear power can be. An answer to that kind of problem. The ship that plays many roles is one of the things that can revolutionize marine technology. In the future. It is possible that the larger ships. The use of the LASH technology can carry smaller freighters on board.
Above: The lighter aboard ship, LASH ship
The next-generation ship system. They can base the LASH-megaship. And smaller ships that they take on board. Those smaller ships carry the cargo to that megafreighter.
“The lighter aboard ship (LASH) system refers to the practice of loading barges (lighters) aboard a bigger vessel for transport. It was developed in response to a need to transport lighters, a type of (usually but not always) unpowered barge, between inland waterways separated by open seas. Lighters are typically towed or pushed around harbors, canals, or rivers and cannot be relocated under their own power. The carrier ships are known variously as LASH carriers, barge carriers, kangaroo ships, or lighter transport ships.” (Wikipedia, Lighter aboard ship)
The system can use two-port technology. The LASH-ship takes a smaller ship inside it from the bow port. And the ship can leave from the LASH-transporter from the bottom of the ship. This allows for loading and reloading those smaller vessels without stopping the LASH freighter. The cargo travels onboard those smaller freighters.
So the nuclear-powered vessel can carry other vessels in its dry pool. When the ship comes near the harbour, it can release those lighter vessels. That can transport. That cargo to the harbour, and then take other lighter vessels onboard. The idea is that the smaller vessels are loaded in the harbour, and then the larger LASH-ship can wait far from the harbour. The nuclear-powered ship must not even stop. It can release the smaller ships and take the other ships on board, even if it moves. That makes those systems more effective than other systems. If those large nuclear-powered ships wait far from the coastline. The harbours will not limit their size. Those smaller freighters can use hydrogen as fuel, and during the trip, the LASH megaship loads those ships’ tanks that it carries.
