Caterpillar Marine announced that Cat power and propulsion offerings have been selected to provide complete propulsion solutions for four ocean-going towing vessels designed by Ulstein Design and Solutions. Each vessel will have four 9 M 32 C propulsion engines, rated at 4,500 bkW at 600 rpm. Also onboard each vessel will be three Cat C32 auxiliary generator sets rated at 940 ekW at 1,800 rpm as well as one Cat C9 generator set to provide emergency power. All four vessels will be equipped with two AEM shaft generators rated at 3,150 ekW at 1,200 rpm. Each vessel has two Cat BCP1330F main propellers, two BTT625 tunnel thrusters and two BTT419 tunnel thrusters. The MaK and Cat power and propulsion solutions will be delivered over the course of the next year.

Designed to tow large structures such as offshore drilling rigs, ULSTEIN SX157 design vessels offer a 300-ton bollard pull and are capable of operating at full loads for 45 days without refueling. The vessels will be constructed at the Niigata Shipyard in Japan. Cat dealer Pon Power led the Caterpillar efforts on the sale in conjunction with Cat Propulsion. Upon completion of construction the vessels will be owned and operated by ALP Maritime Services, which was recently acquired by Teekay Services.

Cat BCP controllable-pitch main propellers have been specifically 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.

Cat tunnel thrusters feature a modular design with modern transmission layout and custom-designed blades to suit each individual application. The complete thruster can be mounted and dismounted in the tunnel (swing-in/swingout design) and can be driven by electric motor or diesel engine. Built to meet the demands of the major classification standards, the thrusters offer customers maximum reliability with minimum downtime and good serviceability.
