STEERPROP AZIMUTH PROPULSORS ORDERED FOR RAMPARTS TUG SERIES

STEERPROP AZIMUTH PROPULSORS ORDERED FOR RAMPARTS TUG SERIES

Wednesday, August 18, 2021 

Uzmar Shipyards in Turkey has chosen Steerprop to deliver six SP 20 WD azimuth propulsion units, each rated for a power of 1,610kW, for a series of three Robert Allan Ltd (RAL) designed RAmparts 2300_UZM tugs currently under construction.

To increase the achieved BP and to improve manoeuvrability, the azimuth propulsors have an electrical steering that enables more efficient use of the main engine’s power compared to hydraulic steering.

Donato Agostinelli, Sales Manager, Steerprop, said: “The Robert Allan designed RAmparts 2300_UZM tugs with 50-plus ton of Bollard Pull are very efficient and agile tugs, providing a lot of performance in a compact package. Since the tugs will be operating in challenging conditions and performing very different tasks throughout their life, the propulsion units must be efficient and reliable under all circumstances. For these reasons, the units also come with our Condition Monitoring system as standard. The agile electrical steering system in our Z-drive azimuth propulsion increases overall performance and reduces the running costs of the vessels. The electrical system can also be upgraded with a battery pack to enhance performance even further, while at the same time lowering the environmental footprint of the system.”

The propulsors’ electric steering gear also offers a constant steering speed, considered essential when performing sensitive tasks like escorting tankers.

“Since the steering uses power only when actively turning, it is very energy-efficient. In addition, the electrical steering also produces significantly less noise than hydraulic steering systems and requires little service due to its mechanically simple construction,” said Agostinelli.

The RAmparts tug class is said to be the world's most popular and widely used tug type, thanks to its flexible design that allows different configurations and applications.

“We identified a clear customer need and saw that we could make the necessary changes to our base design in the short time we had at hand. We think this is a great reference to make a re-entry in a segment that is not new to us, but in which we have not been present for a while,” Agostinelli concluded.
