Modular construction refers to prefabricating building units in a factory and transporting them to the job site for assembly. There have been several advancements in modular construction for ships, including integrated hull outfitting and painting (IHOP) where hull construction, outfitting, and painting occur simultaneously; a ship integrated geometrical modularity approach which standardizes hull parameters; modular platform construction which standardizes ship systems and interfaces; and MEKO design which accommodates all components for a system in standardized modules. These advancements allow for reduced construction timelines and costs as well as easier maintenance and modification.

Modular Construction Advancements
- 1. MODULAR CONSTRUCTION ADVANCEMENTS Akhil Saxena 35th Batch Dept Of Ship Tech C.U.S.A.T. Presented By:
- 2. CONTENTS What is modular construction? Advantages of modular construction Conclusion I II III IV Various advancements in modular construction
- 3. • Modular construction refers to factory-built building units completely assembled or fabricated in a manufacturing plant away from the jobsite, then transported and assembled on site. • Also known as prefabricated construction. • Division of the ship into blocks, sections and modules. Definition MODULAR CONSTRUCTION
- 4. • The division of a larger system into smaller parts or components. • The principle of (relative) self‐sufficiency of the individual parts. • The recombination of the parts into multiple end products, according to a set of “rules” given by an overall systems architecture.
- 5. • Purpose is not “mass customization”, but rather a “divide‐and‐conquer” • Division into chunks that are fit for the production facilities (weight and size of crane, docks, ports, production equipment, etc.) • Modules should also fit the production process (planning units, parallel production, procurement units, material management, etc.). PRINCIPLE
- 6. • Better quality product. • More focus on individual operation. • Reduced time of construction. • Reduced cost of construction. ADVANTAGES
- 9. • Traditional method not enough. • Shipyards have to come up with something more innovative. • This gives rise to advanced modular construction.
- 10. • Stand for Integrated Hull Outfitting and Painting. • Simply put, it is hull construction, outfitting and painting – all at the same time. • Stereotypes of building hull before launching and outfitting after launching and by the Outfitting dock completely changed. • Mainly required to reduce the time spent by the ship in the drydock. IHOP
- 11. • Construction of ship on slipway lasts maximum 16 weeks. • Reduced workload while the ship is docked. • Reduced cost of construction. • Better organisation and coordination of work. •ADVANTAGES
- 12. • Design of Damen Schelde Naval Shipbuilding, Netherland to build Frigates and Corvettes. • A set of geometrical parameters defined which are applied throughout the entire product family. • This resulted in an optimal hull form series, ranging from 50 to 150m in length and 9 to 15m width SHIP INTEGRATED GEOMETRICAL MODULARITY APPROACH
- 13. • Allows the client to compose its own vessel. • Much less time required during construction. • Lower engineering cost. • Easy modification and upgradation. ADVANTAGES
- 15. • Based on experience since the 1980s when a replacement programme of German mine-counter measure vessels started. • Strict modularization of all systems and equipments. • Integrated in an improved design of the common platform. • Standard interface connections. MODULAR PLATFORM CONSTRUCTION
- 16. • Equipments easy to assemble onboard. • Replacement/modification much easier. • Better quality of product. ADVANTAGES
- 17. • MEKO is probably the best-known example of modularity in shipbuilding. • All components needed to run a specific system are accommodated in a single modules. • All modules are connected to the power supply, HVAC, and the data network via standard interfaces. MEKO DESIGN AND CONCEPT
- 18. • Ease of maintenance. • Cost reduction. • Less time spent on the drydock. ADVANTAGES
- 19. • Despite certain disadvantages, modularization is increasingly used by successful shipyards and navies. • Indicates that there is still considerable potential for improvement. • With the ever-increasing competition, the more advanced the level of modularization, more success a yard will attain. CONCLUSION
Hinweis der Redaktion
- In today’s international competitive shipbuilding market, success is often based on offering both competitive prices and competitive delivery dates. So basically, you not only require a improved ship design and better engineering, but we also need to deliver the product faster and at a cheaper price.THIS IS WHERE MODULAR CONSTRUCTION COMES INTO THE PICTURE
- Modular construction- definition and principle.Advancements – IHOP, SIGMA, MOPCO, MEKOAnd the final conclusion
- Manufacturing building components off-site provides for more controlled conditions and allows for improved qualityand precision in the fabrication of the component.Since there will be no delay due to various intersections or interference caused between different sections, the time spent by the ship on the drydock will be much lesser.Major cost during construction is directly proportional to the time spent by the ship on the dry dock. Huge reductoion in cost, with all the same architectural aesthetics you would expect from traditional building methods.
- When modular construction was first introduced, we used to divide the ship in various block from fore to aft. Irrespective of the nature and functioning, these blocks were divided, and built independently in the shipyard. The world’s most productive shipyard have come with various modifications and improvements to give rise to something called ADVANCED MODULAR CONSTRUCTION. No fundamentals.. Just creative thinking
- German shipyard Abeking & Rasmussen (A & R)
- Depending upon the particular task they are required to perform, a distinction is made between weapons, electronics and the ship's technical modules.
- Only Containers and mast modules are installed during the construction phase.
