A warship or a commercial ship was made out from a shipyard specifically made for such ships. In such a case, it takes longer time just to finish a hull. Here is the step-by-step process as to how a ship was built.

Speaking of the contents of this article, it should be on the Pitz Defense Analysis blog since this was also pertaining to warships. However, for the sake of discussion regarding ships in general, it was deemed worthy to have such post to be here on this site.

In this case, it will be centering to a contract undertaking by the Government and the shipyard where the bid has won. Other details were pertain in this link. And it was also discussed that building warships are different to commercial once in which it was dealing with compartmentalization, purpose, the thickness of the steel in a hull, metallurgy and other factors that differentiate such hulls. Not also to mention the variations as to how such hulls were built.

However, the process are indeed almost similar in production and is worthy to have a separate entry pertaining to it.

Many times those milestones also mark where the partial payments of the ship are done. In this case, we will be talking about the recently-built BRP Tarlac LPD or its project name, SSV-1.

1. Signing of Contract – When signing the contract a ceremony usually will be held at the shipyard and this is a starting point for the shipyard to begin its process for building the ship. Normally the first payment is done when the contract is signed. The ship is also officially given a hull number and an IMO number which is unique identity that will follow the ship throughout its lifetime.

2. Production Design – The production design organizes the design information in the detailed plans into respective component information. The production design enables the field staff to meticulously control a large amount of components on site.

3. Material and Equipment Purchase – At this stage yards starts purchase all material and equipment need to complete the vessel. Since a tremendous volume of materials need to be ordered to build a ship, it is vital to manage and supervise the delivery dates of those materials so that the procurement is timely and accurate.

4. Production Plan – The production plan has a critical impact on manufacturing efficiency due to the enormous amount of components and the large number of workers involved on the job site. It is vital, therefore, to plan thoroughly so as to control and supervise the flow of materials, work volume, job assignments and subsequent progress of the shipbuilding process.

5. Steel Cutting – Steel plates are being cut in to the parts that will form the the hull and deck sections of the ship. The process of heating and bending a steel plate into curved shapes is of great importance in shipbuilding, and requiries sophisticated skill and technique. Normally second payment will take place at this stage.

6. Keel Laying Assembly and Mounting of Ship Sections – The cut steel is assembled into smaller blocks that in turn are assembled into larger sections that mounted together to finally become a complete ship. Third payment is done at this stage.

7. Launching – When all the blocks are mounted and jointed, launching is the next stage. While the launching at a dock simply means filling the dock with water to float the ship, the launching from a building berth is a very impressive and exciting sight to see since the ship slides its way majestically into the sea. This is one of the most thrilling moments for all involved with the shipbuilding process. Fourth payment will normally take place during launching.

8. Finishing of the Vessel – After launching the vessel is finished up at the quay. Starting with finishing work of accommodation and control sections, every equipment and instrument is checked and re-examined in practice. We are now in the final stretch of shipbuilding.

9. Sea Trial – At sea trial the ship and ship equipment performance is tested and the result is kept as a performance record of the vessel.

10. Delivery – A new ship is born. After the delivery ceremony, the captain, chief engineer and crew embark for the ship’s maiden voyage. Final payment is done at delivery.

11. Warranty – Warranty period of a new ship is usually 12 – 24 months depending on the contract.

FACTS ON SHIP COMMISSIONING


Ship commissioning is the act or ceremony of placing a ship in active service, and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to the placing of a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries old naval tradition.

Fact, BRP Tarlac LD-601 has done the commissioning ceremony just recently last June 1st, 2016. So by that fact, BRP Tarlac is Philippines active warship.

CONCLUSION

The process is done in an orderly and legal fashion citing that it was upon the knowledge of the two opposing sides signing the contracts that the finished product must serve the customer well under the assumption that future orders may take place citing that such ship satisfy the needs and wants of the end user. Also with that, ships play the role wither in ruling the seas or connecting shipping lanes and with that shipbuilding industries have a huge responsibility to have their ships strong and sturdy enough to cope with the rolling waves as well as having the quality of the mechanisms used such as the engines in which the ship will have an excellent performance in doing its role. Overall, shipbuilders will definitely never let their customers down.
