English to Portuguese Tech/Engineering Petroleum Eng/Sci PROGRAMA DE RECUPERAÇÃO

Prezados Colegas,

Gostaria de saber a melhor tradução para CONTROL PITCH PROPELLER SYSTEM no seguinte contexto:

"XX will prepare, train and certify technical people and teams to attend ZZ Vessels, according to our fleet attendance parameters, considering also the ZZ fleet incoming new ships;

4.3 XX will have "ready for attendance", according our Contract, enough quantity of teams & specialized people for repairing our Main and Auxiliary Engines; CONTROL PITCH PROPELLER SYSTEMS, and all equipment and systems made by WARTSILA;

4.4 XX will inform for each kind of XX employee (fitters, mechanical, supervisor, Service Engineer, others) involved in our Services Contract, all the XX requirements regarding technical courses, theoretical graduation and practical experience;

4.5 XX Workshop services availability for repairing used and/or damaged parts and components."

Para PITCH PROPELLER SYSTEM encontrei: Sistema de Hélice de Passo. O que me intriga é a palavra CONTROL. Devo traduzir a expressão como Sistema de Hélice de Passo Controlável?

Desde já agradeço sua valiosíssima ajuda!! Abs
