Various advancements in modular construction

• 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.

DefinitionMODULAR CONSTRUCTION

• 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.

• 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

• Better quality product.

• More focus on individual operation.

• Reduced time of construction.

• Reduced cost of construction.

ADVANTAGES

ADVANCEMENTS IN MODULAR

CONSTRUCTION

• Traditional method not enough.

• Shipyards have to come up with something more innovative.

• This gives rise to advanced modular construction.

• 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

• 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

• 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

• Allows the client to compose its own vessel.

• Much less time required during construction.

• Lower engineering cost.

• Easy modification and upgradation.

ADVANTAGES

• 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

• Equipments easy to assemble onboard.

• Replacement/modification much easier.

• Better quality of product.

ADVANTAGES

• 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

• Ease of maintenance.

• Cost reduction.

• Less time spent on the drydock.

ADVANTAGES

• 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.
