Modular design

  • Mission driven requirements
  • Prepared for future upgrades with design margins
  • Easy replacement and standardised interfaces

Operational Availability

  • Focus early on maintainability and Maintenance

access

  • Designed to minimize maintenance time

Cost effectiveness

  • Replenishment effectiveness
  • Low manning requirements – highly automated
  • Planned and budgeted modifications and upgrades

within Life Cycle Costing scope

  • A design method with balanced

requirements stated from operational needs - mission oriented

  • A submarine enterprise, where

stakeholders have complementary competences

  • A design that takes the demands and

needs for production and maintenance into account

Very complex operational environment:

  • Very shallow (50 m in average)
  • Complex hydroacoustic conditions
  • Complex archipelagos, heavy sea traffic
  • Large # (>50 000) of mines and ordnances

Naval technical requirements:

  • Shallow draught, bottoming capability
  • Sensors able to handle a cluttered situation
  • High manoeuvrability - fast reaction times
  • High shock resistance and low signatures

Upgrades & Modifications - Parallell system development Use a verified Baseline of Technology inside projects Minimize project risk through rigorous design and construction tests Development outside the project (independent) Many systems used in Gotland MLU are paving the way for Blekinge cutting edge capabilities.

Blekinge

This makes Gotland a clear step in the evolutionary chain of submarines

Availability in focus early in the design:

  • Systems & Components - Reliability
  • Integration - Maintenance access
  • Modularity - Easy replacement
  • Standardised interfaces - COTS solutions

The purpose of this is to ensure:

  • Balanced life cycle cost - Affordability
  • Optimum reliability and maintainability (R&M)
  • Optimum design for maintenance and supportability
  • Minimum maintenance training requirements

  • No large exclusive MLU. Instead major

capability upgrades will be done during the Full Cycle Docking.

  • Continuous Through Life Support

  • Cost effectiveness is driven by reliability

(i.e. how much performance can you get for your money?)

  • Reliability [R] tells information about the

failure-free interval (i.e. how many failures can you afford?)

  • Operational availability [Ao] tells information

about how you use time (i.e. how much can you afford to spend to avoid failures?)

  • Hydraulically powered with manual back-up for quick,

safe and reliable operation.

  • Central control station with remote control facilities.
  • Low manning requirements – highly automated.
  • The entire system is included on board the submarine.

A simple crane is all that is needed ashore for loading.

  • High reload stowage density.
  • The reload equipment is resiliently mounted for

protection against shock.

  • Low noise signature enables the reload equipment to

be used under silent running conditions.

  • With a mission-oriented approach complemented with

parallel system development it is possible to integrate new and improved technologies at justifiable risk levels

  • The purpose is to increase the number of days at sea

and minimise the number of days at the shipyard.

  • The overall objective is to provide the end user with a

submarine with optimal availability, in the most cost efficient way.
