Lifesaving Systems

• Founded in June 2009 after 2 years of development

• Drop-In-Ball and winch system developed with NORSOK R-002 in mind

• First NORSOK R-002 project began around January 2010

• 10 Nadiro employees has been working for a year on NORSOK R-002 development project

• So far app. 50 M DKK has been invested in Nadiro A/S, a majority invested in R&D and

production of NORSOK R-002 compliant equipment.

Lifesaving Systems

• Maintenance and repairs eased by hatches and lifting lugs

• Container rests on each corner with shock absorbers included

• Emergency stop isolates the winch from the rest of the system

• Environmental protection by ventilation and de-humidification

• Structural safety factors according to NORSOK R-002

• Insulated container panels prevents condensation

• Lifeboat is stabilized inside container

NORSOK R-002 system features:

Oil motor for hoisting with over-load protection

Primary brakes: disc brakes. Secondary brake: oil brake

In case of disc brake failure (no braking torque), oil brake

acts as back-up brake (descent continues without

consequences)

Redundancy in hydraulic supply system

Possibility to ascent the system in no power condition

In case of no power and no back-up power descent

activated by “Pull’n’Go” handle performing descent with oil

brake

Disc brakes are hydraulically activated by accumulators

connected to back-up power system

Back-up accumulator to “start ” descent in case of no

hydraulic pressure

Lifesaving SystemsBoat-In-A-Box – Hydraulics

Lifesaving Systems

• Fully redundant release system (single failure)

• Release is not dependent on gravity

• Release can be done with primary or back-up system

• Mode-selector implemented on deck control panel

• Indicator shows when the hydrostatic device is activated and when balls are disengaged
