PERCEPTION Shipyard Features
Planning & Production Management Software Systems to Shipyards

The PERCEPTION database is customized to facilitate the use of most modern concepts of ship building technology, including Integrated Hull Outfit Production (“IHOP”).   IHOP is characterized by hull block fabrication and erection that is integrated with zone outfitting to provide precise zone-by-stage control at four basic stages of construction:

1.     On-unit,

2.     On-block and

3.     Onboard outfitting, and a sub stage for

4.     Down hand outfitting on overheads when blocks are upside down.

 The benefits from IHOP include the following:

1.     Reduce outfit time

2.     Minimize outfit onboard, a more expensive stage of construction.

3.     Simplify outfit planning.

4.     Increase efficiency in use of facilities like lifts and cranes

  IHOP results in

1.     Reduced overhead cost

2.     Improved lighting/ventilation for outfit work

3.     Reduce work at high places

4.     Improved safety/working environment.

5.     Higher productivity.

6.     Better quality.

The overriding goal for IHOP is to increase productivity for the entire shipbuilding system.    The underlining principal of IHOP planning is not to make production work harder but smarter.
