Operation of pipelines implies a high level of supervision in order to minimize
accidents and incidents, so the detections of abnormal operation is paramount.
In the state of the art, there are several developments of pipes structural health
monitoring (strain or crack formation), and also flow monitoring, by acquiring
parameters associated to the transported fluid like pressure, but there are a few
developments comprising both structural and flow at the same time. This work
deals with the design for the manufacturing of a multi-parameter tubular sensor
made on composite material, with optical fiber sensors embedded as well as
other conventional sensors. The aim is the detection of transient signals
produced by events somewhere on the pipeline like closing or opening of valves,
or leakages, and measure axial loads, and bending moments. The design
process is divided in three aspects; the first one is the requirement identification
by the stakeholders, where a Quality Functions Deployment (QFD) technic is
employed, in order to arrive to the engineering specifications and design goals.
The second design stage represents the conceptual design, for which a
functional analysis is done, followed by a phase of concept generation according
to the identified functions; several combinations of concepts are obtained and
then are evaluated in terms of the degree of the requirements satisfaction, in
order to get the global device concept. Finally, the third stage correspond to the
detailed design, where an iterative process takes place of sizing, material
configuration, manufacturing process and calculus, which finishes with the
engineering drawings. Calculations performed evidence that the established
sizing fulfils the requirements.
