Schottel Supplying Harbor Tug Propulsion Units

By Jack Burke19 February 2020

Schottel will supply propulsion units for an escort and harbor tug built by Turkish shipbuilder Med Marine.

The main propulsion for the RAmparts 3200 tug consists of a pair of Schottel Rudderpropellers type SRP 460 CP – each driven by a diesel engine with 2350 kW. The four-bladed controllable pitch propellers with a diameter of 2.70 m are designed to ensure maximum vessel maneuverability as well as top propulsion efficiency. This thruster configuration will enable an expected bollard pull of about 75 tons and a free running speed of approximately 12.5 knots.

The Robert-Allan-designed tugboat is under construction at the Ereğli Shipyard in Northern Turkey. It will be used for harbor and terminal operations as well as for coastal towing.

“Schottel is a company which proves itself in the marine business through its technical understanding and quality,” said Recai Hakan Şen, CEO of Med Marine. “Equipping our tugs with their propulsion solutions contributes to the sailability of our vessels. Working with Schottel, which is very professional and successful in technical issues, is quite easy and enjoyable.”

To date, more than 1000 Schottel Rudderpropellers types 460 and 490 have been delivered. Rudderpropellers with a maximum power rating for tug duties between 2350 and 2550 kW per engine – such as the SRP 460 and the SRP 490 – are among those Schottel azimuth thrusters that have received several technical updates in order to offer customers state-of-the-art design, construction and economical operation. The SRP 460 (formerly SRP 1515) was first delivered in 1999.

The new tug is scheduled to enter service in the fourth quarter of 2020.
