Challenges Navies have to meet today

3

� Sufficient capability and reliable function of Naval vessels & their systems

� High safety level for crew on board andall embarked persons

� Latest technology exploitation

� Readiness for changed operational profiles e.g. special forces, higher autonomy, integration of unmanned systems

� Environmental Responsibility

Budget limitations

Shrinking personnel

numbers

Mismatch of available in-

house expertise for

shipbuilding & design

Increased public

awareness for safety

and the environment

What about military requirements?

What makes a naval ship different from a commercial vessel?

Study shows: Large common basis

Some Generic differences

DNV GL © 2013

What regulations apply to a Navy vessel ?

� For naval vessels, no unified and obligatory set of regulations exists or is in force.

Further, the responsibility for the safety and security of this vessel is usually not

the responsibility of the "civil" flag administration of the country. In most cases

the function of the flag state is executed by a special department of the ministry

of defense. This authority is the so called "Naval Authority" or "Naval

Administration" (NA).

� The NA's are not globally organized as known from civil shipping (e.g. IMO); no

common understanding of safety and security exists with respect to naval vessels.

Only within a combat league, e.g. NATO, a common basic understanding of safety

and security as well as common basic regulations as STANAG; STANREC and

ANEP exist. In principal, the NA of each country could decide which level of safety

and security as well as which standards will be applied to the vessel.

Why is it a good match?

Service experience from more than 60 000 vessels over a period of more than 150 years is a benefit for both commercial and naval vessels

Smoother execution of newbuilding projects by using a Class naval services

Providing there is willingness to accept the terms of the game

Use of Class improves project execution

Limiting factors for the Yard:

� Special solutions

� Detailed specification

� Fixed alternatives

� Unknown factors

� Rigid specifications

Improvement factors for the Yard:

� Known standard and solutions

� Flexible specification, however, freedom to optimize

� Access to global best practices

� Consistent quality

Case Studies– OPV and Frigates Hull Lines Optimization

Offshore patrol vessel

� Hull optimisation for new OPV for Latin American navy

� 6 weighted combinations of speed & draft; 14,000 design variants

� Power requirements reduced by >20%

Frigate

� Hull optimization for German Navy F125 frigate

� Optimization for minimum power (keeping displacement and stability in calm water and waves); 27,000 design variants

� Power requirements reduced by 7%

Hull extension for frigate

� Hull optimization of German Navy F123 aft hull extension

� Optimization for power and stability at 18kn and 30kn; 10,000 design variants

� Requirement elucidation lead to stability improvement for constant power

Future challenges for the Naval industry building an OPV

� What are the challenges for Naval designers and yards?

– Increase of operational availability of vessels

– Doing more with fewer ships by enhancing flexibility

– Extended operational use before returning to base

– Remote condition monitoring

– Condition based maintenance

– Virtual Training

– Flexible design with a high degree of modularity

– Non-hardened / non-combatant multi-role designs

– Common spare part concepts

– Naval Ship Code, Naval Submarine Code, SubSafe or national standards as Safety Regimes
