So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

21st Century Shipbuilding Fuels Steel, Engine Industries

By Timothy Posh


Shipbuilding is one of the world's biggest industries. The world's largest shipyard is found in Ulsan, South Korea. Other nations in Asia are growing to be foremost competitors in shipbuilding as well.

Some 60,000 years ago when man first constructed a ship, the process of building a ship only involved handiwork, stones for carving, and wood to build the ship's body. Today, ships are among mega structures that are considered an engineering feat.

21st century systems make shipbuilding expeditious. The method utilised today entails block construction, which implies, superstructures of the ship are pre-fabricated by sub-contractors. In placing a ship together, therefore, numerous other industries are in action, including the engine producers, the steel producers and also the sub-contractors for pre-fabricated components just like the hull, decks, among others.

To start with, a maritime architect is commissioned to design the ship. He carefully reviews the state of the ship as it sets to sea. As an example, he analyses the hydrostatics, which is the state of the ship while resting on the water and its ability to remain floating. The naval architect also designs the ship in keeping with stability, which is its capacity to restore itself back to place in cases where the wind, wave, or the water inclines it or tips it over.

The naval architect also studies hydrodynamics, which is the ship's capability to propel itself on the water. Part of hydrodynamics is the consideration for ship movement and maneuvering, which is the capability of the ship to maneuver amidst waves.

Formerly, the naval architect will build a model vessel to evaluate both hydrostatics and hydrodynamic properties. Contemporary equipment has the naval architect using computer software programmes that simulates the ship's performance on the water through a representation ship created on the computer.

Shipbuilding is a vital industry in any world wealth since it makes viable the installation of sea vessels for passengers, cargo, war-time use, and scientific explorations.
