US NEWBUILD RELIES ON SCHOTTEL PROPULSION SYSTEMS

Monday, March 18, 2019 

‘Paul Candies’, a new Inspection Maintenance Repair (IMR) vessel built by Candies Shipbuilders and owned by its parent company Otto Candies, is equipped with three different Schottel propulsion systems.

Two Combi Drives, two transverse thrusters and one retractable rudderpropeller ensure maximum manoeuvrability and a high free running speed for the US-flagged IMR vessel.

The two type SCD 560 STP Schottel Combi Drive azimuth thrusters help the diesel-electric vessel to reach a speed of 14 knots. The 2600kW SCD 560 STP features the Schottel twin propeller concept. By sharing the load between two propellers, this increases propulsion efficiency and reduces fuel consumption in comparison with single propeller systems. Two type STT 5 FP bow thrusters (each of 1,050 kW) and one 800 kW type SRP 260 R FP retractable bow thruster ensure precise and high manoeuvrability in DP mode.

“We have relied on Schottel products for many years. Several of our vessels are equipped with propulsion systems from Schottel – some even with the electric Combi Drive,” said Otto B. Candies III, Vice Chairman, Otto Candies. “As a result of the very good performance of the azimuth thrusters and the reduced service and maintenance efforts, we have once again decided in favour of Schottel’s Combi Drive.”

Otto Candies deploys the MT6020 Marin Teknikk design vessel in the worldwide offshore industry. The 101.25m long and 20.60m wide vessel is named after Paul Candies, the long-time President of Otto Candies. Paul Candies joins 42 other vessels in the company’s fleet.

With the SCD L-Drive design principle, the electric motor is integrated vertically into the rudderpropeller, resulting in a high efficiency variant of the SRP and STP propulsion units. The elimination of the upper gearbox has several advantages such as reduced mechanical losses, low noise and vibration levels as well as fewer maintenance requirements. The SCD therefore features a very compact thruster, offering about 20% space savings compared to a Z-Drive installation. This gives additional room for further equipment and allows reduced deck height.
