LIFELINE AND LIFE RING SUBSYSTEM
The lifeline subsystem is installed along the sides of the RRDF platform to protect personnel from falling overboard.
The stanchions for the lifelines are installed in the turn-tube fittings and ISO corner fittings of the modules. Chain is
used to span the gap between section openings. The lifeline arrangement will vary depending on RRDF
configuration. The life rings, nylon rope and strobe lights are attached to the lifeline stanchions.
The components of the lifeline subsystem consist of stanchions (two types), deck fittings (two types) and chain to
span the spaces between sections. The components of the life ring subsystem consist of a donut shaped flotation
device, nylon rope and strobe light.
EMERGENCY ANCHORING SYSTEM (EASY)
The EASY is housed in a 20 ft ISO container which is placed and secured on the upstream end of the RRDF near the
forward edge. The anchor end of the EASY container should be located 24 in. from the upstream deck edge to allow
enough room for opening of the anchor-end container doors and to allow the anchor to deploy properly.
The EASY is provided to anchor the RRDF platform in the event that the sealift vessel departs the operating area due
to weather or some other contingency. It is designed to hold the RRDF platform in its anchored position through
Sea State 4 conditions. In more severe conditions, the EASY will control the drift of the platform. Major components
of the EASY system, in addition to the container, are the mooring, the stowage and deployment frame that is secured
within the ISO container, the mooring box, two manual hydraulic pumps for actuating the moving parts of the
stowage/deployment frame and flexor receiver adaptors that are used to secure the mooring bridle to flexor receivers
on end rake modules.
