2-15. Controlled bunch of Bay. (figure 2-15) Controlled launch (off-loading) of either the ramp or interior bay
into water is performed as detailed in the following steps. The crew required will consist of an operator and an assistant.
When an assistant is not assigned to stay with the transporter, a temporary assistant maybe designated from the staging
area crew or shuttle crew for duties to be performed at the launch site. This will generally be the case in rapid bridge
construction. The operator will drive and be responsible for operation of the boom and winch. The assistant duties will
be to handle the winch cable and give hand signals to the operator during controlled launch. Both operator and assistant
will prepare the bay and transporter for launch, with the operator responsible for the completion of the tasks. Steps ((l))
through ((9)) may be accomplished at staging area site to reduce launch time. A minimum depth of 30 in. (76.2 cm) of
water is desired for launching a bay, but a bay can be launched in 17 in. (43.2 cm) of water if care is taken.
No personnel or equipment will be allowed to operate upstream of the ribbon bridge. All launching of bays
and boat operation will be downstream of the bridge line.
A safety boat will be used during all water operations.
(1) Ensure all bilge plugs are installed.
