ROT

ROTs are defined as dedicated, unmanned, subsea tools used for remote installation or module replacement tasks that require lift capacity beyond that of free-swimming ROV/AUV systems. Complete ROT intervention systems typically consist of wire suspended tools with a dedicated control system and support/handling system. ROTs are typically deployed on liftwires or a combined liftwire/umbilical. Some ROTs are also designed for deployment on drillpipe. Lateral guidance of the tools may be via guidelines, dedicated thrusters and/or ROV assistance.
