High Performance Couplings for New OSVs
01 Jun 2004
West Yorkshire UK based Renold Hi-Tec Couplings has been awarded a contract to supply high performance DCB 838.0 rubber in compression shaft couplings for marine propulsion systems to be installed in a fleet of anchor handling tug/supply vessels.
The first of the vessels, MV JP Laborde, is under construction at the Yantai Raffles Shipyard Company Ltd in China.
The couplings are to be manufactured under ABS Survey and feature oil injection shaft mounting and a drop out feature which allows access to the motor bearings without the need to remove adjacent machinery.
To be operated by Tidewater Marine of New Orleans USA, each 282ft dynamically positioned vessel will have a bollard pull of over 200 tonnes and the ability to handle anchors at depths exceeding 500ft.
The GPS control will keep the vessel constantly on station.
The load on the coupling is reversible and highly dynamic.
Renold was awarded the contract by Karl Senner Inc, which is responsible for supplying Reintjes DLG 4447U twin input/ single output reduction gears for the five vessels.
The DCB couplings are to be installed in the drive train between each of the Amerimex electric motors and the reduction gearboxes which in turn drive the azimuthing reversible thrusters which provide the propulsion.
