Controllable pitch propeller(CPP) can move blade pitch angle and change vessel's direction without reversing device Crank pin shear stress of trunnion bearing type assembly is a smaller than collar bearing type assembly. Trunnion bearing type assembly is a stronger than collar bearing type assembly. For improved quality and optimized designing of CPP, the structural analysis is need to compare collar bearing type with trunnion bearing type assembly by various methods. Also the results of it's analysis is necessary to choose type of CPP hub and structure mechanism in connection with vessel purpose.

There are two kinds of hub mechanism on the controllable pitch propeller. One is the collar type and the other is the trunnion type. Pitch variation mechanism of the collar type of CPP is a simpler and cheaper solution, therefore CPP of this type is more applicable for commercial vessels. But the trunnion type of CPP has many advantages compared to the collar type of CPP : There are an ability to install up to 7 blades and a smaller dependency from bolt properties. The blades arrangement of trunnion type does not need bolts and it has a smaller disk factors for the same number of blades compared with the collar type CPP. In this instance, the CPP of trunnion type is an appropriate fit for the naval purposes(explosive shock) and ice breakers.
