Schottel Propulsion System for New Coastal Transport Vessel

MV Coastal Standard is the new addition to Coastal Transportation’s fleet. The Seattle-based company owns and operates a fleet of cargo vessels sailing from Seattle to ports throughout Western Alaska and the Aleutian Islands, delivering cargo such as construction equipment, fishing supplies, household goods and refrigerated perishables. For these services, fast and reliable vessels with excellent manoeuvring properties are essential.

The Coastal Standard was built at Dakota Creek Industries Shipyard in Anacortes, Washington with a design developed to maximise cargo carrying capacity while minimising construction and operating costs. The 2200 DWT freighter vessel is 242 feet long with nine single cabins for crew and one cabin with four crew berths for extra crew or guests.

The Schottel propulsion system is an important part of the vessel’s concept. The robust Schottel Controllable Pitch Propeller (SCP) type SCP 77/4-XG (2.300 kW) provides a high free running speed and excellent manoeuvrability and operability, with no need for a reversing gear – contrary to conventional shaft line solutions. The pitch of the propeller blades can be adjusted for manoeuvring and to adapt to changing operating conditions. The SCP is supported by two Schottel pump Jets (SPJ) 85 RD (360 kW each). The two SPJs are fully capable azimuth thrusters, enclosed completely in the vessel’s hull. They are manoeuvring aids and, at the same time, redundant take-home devices. For the customers and employees of Coastal Transportation this means the utmost in safety and reliability.
