COST MANAGEMENT IN SHIPBUILDING
Case Studies Software System "CostFact"
NSRP Joint Panel Meeting
San Diego, CA, USA
December 8, 2015
Develop new ships at competitive costs. Combine engineering know-how and costing experience to ascertain the real costs of new vessels and generate reliable quotations very quickly.
2
CostFact is the number one in maritime specialized costing software.It is developed in close cooperation with several of the world’s leading shipyards, which means that a number of best-practice methods have been incorporatedinto the system, covering all of a shipyard’s calculation demands.

Efficiency & Quality
Cost estimations based on existing calculations allow to generate reliable quotations very quickly.
“CostFact reduces the time until a first cost indication is available from 14 days to 4 hours.”
Oliver Andresen, ThyssenKrupp Marine Systems (Hamburg, Germany)

Company “SSI” and Software Product “ShipConstructor”
SSI develops autodesk based solutions for the shipbuilding and offshore industry
ShipConstructor:
Suite of software products designed for engineering and construction in the shipbuilding industry.
With AutoCAD providing the underlying CAD engine, the user environment is a globally recognized CAD/CAM standard
31
Utilization of CAD model data in CostFact
By the interface to ShipConstructor, the corresponding attributes of technical parameters can always match the current data of the CAD model.
32
CAD changes are shown in the project overview
If model data in the CAD system change due to decisions in the design department, CostFact checks whether these changes affect the calculation. In case of identified cost impact, CostFact shows an alert in the project administration.
33
In-depth information on the impact of CAD data changes
After selecting a parameter in the list on the left, this list on the right shows the utilization of its attribute for parametrical calculation.
The column “Usage” shows the number of different cost items, calculated based on the respective parameter.
The parameters with changed CAD values are highlighted
34
Updating the project automatically
By clicking the alert, a context menu appears that enables the user to:
Update the project, according to the current CAD attributes
Update the project, according to the current CAD attributes while the previous version is automatically saved as a project revision
Create a new project, which is based on current CAD attributes

Capability Costing at ThyssenKrupp Marine Systems
36
ThyssenKrupp Marine Systems, Operating Unit Surface Vessels
One of the leading system providers for high-end naval vessels with more than 3,200 employees in Germany (including operating unit submarines).
Development of a new product family:
Addressing changing future requirements
Simultaneous optimization of costs and technical value
Consistently oriented along target costing
37
Cost management starts with the definition of a cost target

Sales Department:
1. Defining capabilities
2. Analysing the value of each capability
Contrasting Cost and Value
Target Costing strives for a balanced relation of value and cost
Cost cutting activities have to focus on capabilities with low value and currently high cost
