THE BEGINNING – STEERING COMMITTEEBACKGROUND : Organisation of Defense in France

•President of Republic is responsible for

• Defense Policy

• Decisions in case of emergency situations

•Chief of armies reports directly to him

• Chief of Navy –is responsible for the

• definition of Navy needs including technical specifications for new equipment

• operational evaluation of prototypes

• use of equipment by the navy forces

•Minister of Defense –under supervision of Prime Minister- is responsible through

• DGA of :

• prospective analysis of needs

• bringing proper equipment to the forces

• defining and monitoring technology and industrial strategies


BACKGROUND : Request for BV involvement

•Starting several years ago, but in a more comprehensive way for military units from early 2000:

• Navy –expressed the wish to involve classification society (BV) to

• better comply with Solas, Marpol,…

• use more « commonly used in Merchant Marine» equipment and technologies

• define «commonly agreed technical standards » for discussions with DGA, Yards, …

Later:

• provide structured process for regular inspection for vessels in service

• DGA confirmed the wish of French Navy and emphasized the interest for the use of BV

• to benefit more, starting at design stage, from experience of non military best standards;

• allowing easier purchase, and more competitive offers from yards and equipment suppliers;

• with understanding miltary specificities (crewing, weapons, …) through « adapted » rules

• DCN understood that BV could bring:

• benefit through good guidance for design, and more « common » equipment requirements,

• more clarity in all discussions between DGA and yards military or non military.


BV EXPERIENCE

� INVOLVED IN NAVAL SHIP BUILDING SINCE 1978Patrol ships - Watch frigates - Landing ships- Replenishment tankers – Vehicle carriers

� STEEL SHIP RULES APPLIED TO NAVY SHIPS

Parts of BV & IMO rules were applied to French navy ships

� STRONG CO-OPERATION WITH

THE FRENCH NAVY/MINISTRY OF DEFENSE (DGA)

At pre- design stage

After building contract signed

-approval of drawings

-survey of buildings

-attendance to tests, trials and delivery

After delivery follow up of vessels with regular inspections, reports,…

New request from DGA: certification/conformity assessment for vessels builtabroad.

Confidentialiy procedure is strictly followed in here above processes.

BACKGROUND : BV Experience

� Survey Regime is not constrained by International Conventions

� Survey Cycle over 6 years (against 5 yrs for merchant ships)

� Use of planned maintenance scheme taken into consideration

� Option to qualify chief engineer/naval technicians for survey of engineering systems

Part A : Survey regime

BV MILITARY SHIPS RULESSPECIFIC NAVAL REQUIREMENTS


STABILITY STABILITY -- SURVIVABILITYSURVIVABILITY

� Stronger wind conditions than for merchant ships

� Subdivision determined by damage stability criteria

� Max angle of heel larger than for merchant ships

� Additional notation FFS Flooding Fighting Systems

BV MILITARY SHIPS RULESSPECIFIC NAVAL REQUIREMENTS


• Yielding check : increase of vertical wave bending moment by 10%( only for « frigate » and for « aircraft carrier » )

• Ultimate strength : increase of PSF* from 1.1 to 1.2

• Fatigue criteria for design life over 30 years ( up to 40 years )

HULL GIRDER STRENGTHHULL GIRDER STRENGTH

* PSF : partial safety factor



PROPULSIONPROPULSION

Insertions :

- continual operation with a partially flooded machinery compartment

- increase of admissible heel angles for damage stability verifications

- constraints with respect to NBC openings protection

- Increase of safety coefficients for gearboxes
