Use[edit]
Two members only are need for the use of the LR5 but in normal conditions, usually 3 crew members are needed : the pilot, the co-pilot and the system operator. For the operating conditions, the LR5 is able to operate in seastate conditions of 5 m maximum and its safe operating depth is limited to 500 m. Eight trips can be done with LR5 before battery recharge need which makes the LR5 able to save 120 sailors for one full charge of 8 trips. The LR5 submersible is fitted with an integrated navigation and tracking outfit. This system, developed by Kongsberg Simrad, integrates the surface and subsea navigation data.[4]
History[edit]
