RIO DE JANEIRO – Caterpillar Marine reports that Cat power and propulsion solutions have been selected to power four AHTS vessels for Grupo CBO, marking the entrance of Cat Propulsion into the Brazilian marine sector.
Each AHTS vessel will be equipped with 4 x 6 M 32 C propulsion engines rated at 3000 bkW and Cat Propulsion controllable pitch propellers. Additionally, Cat will again power the third PSV in a series for Grupo CBO with 4 x 3512C diesel electric propulsion (DEP) generator sets rated at 1700 ekW, as well as 1x C18 for harbor/emergency power. The 180-ton (163-metric-ton) bollard pull AHTS vessels will be designed by Hayvard Design and Solutions, using an adapted version of its 843 design.
Cat dealer Sotreq led the Caterpillar efforts on this landmark project for the Brazilian market, and will continue to manage the delivery and subsequent service of the Cat solutions.
Cat BCP controllable-pitch main propellers are designed and developed for heavy-duty applications with the pitch setting hydraulic servo cylinder in the hub. The hub lubrication system is a unique oil circulating system with an integrated moisture monitoring system. This is the first hub system in the shipbuilding industry where the moisture content is constantly checked, making it possible to protect the entire propeller system as well as the environment.
