Shipyard
A shipyard (also called a dockyard) is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.
Ship management
Ship managers are companies who accepting the commission of the shipowners or charterers and the ship operator engaged in ship management. This includes the narrow technical management of ships, registration of vessels, operations, service, technical maintenance, as well as management of crew, among other. It can also include the business and commercial management of a vessel, such as its chartering and financial administration. As long as companies who comply with the characteristics above, they can classified as a ship manager and their duties are based on the pre-agreed and trust relationship with the ship owners.
