Schottel will supply thrusters for tug newbuildings for at least two more years within a framework agreement with Sanmar
Sanmar Shipyards signed the contract with Schottel to exclusively supply azimuthal thrusters with controllable pitch (CP) propellers for Bigaçay-class tugs built to a Robert Allan design by Sanmar. These tugs will have bollard pulls up to 90 tonnes.
“The agreement puts Sanmar in a position of a contractual partner offering the latest propulsion technology with Schottel exclusively providing our shipyards with two 2,700-kW rudderpropellers type SRP 560 CP for each vessel of the Bigaçay tugboat class,” explains Sanmar head of procurement Hakan Tunc.
Schottel chief executive Stefan Kaul said this “trusted partnership is going from strength to strength” follow the contract signing.
Sanmar has installed Schottel propulsion on its tugs since 2004. Milestone orders include Schottel rudderpropellers for the Sirapinar-class azimuth stern drive terminal tugs, 17 of which are already in operation.
A recent example was a contract for the supply of SRP 560 CP configuration thrusters for two tugboats Sanmar is building, with 90 tonnes of bollard pull, for the Turkish Directorate General of Coastal Safety.
Schottel is also pencilled in to supply rudderpropellers for tugs Sanmar plans to build with hybrid propulsion.
Sanmar’s experience with hybrid propulsion passed a milestone in Q1 2020, when it completed Boğaçay XXXVIII to a Robert Allan design. This tug had the world’s first advanced variable drive (AVD) and hydro-mechanical hybrid propulsion in the marine segment.
Caterpillar supplied an AVD for continuously variable transmission, which can modulate propeller speed down to zero revolutions by a slipping clutch.
Earlier this month, Sanmar redelivered 1985-built and 24.75-m long tug Ozgur to Cyprus Turkish Safety & Salvage Co after extensive modernisation and restoration work at the Altinova shipyard. Ozgur achieved a top speed of 11.1 knots and reached a bollard pull of 9.7 tonnes after the refit. After its delivery, this tug will restart operations in the eastern Mediterranean.
Propulsion technology will be discussed in depth during Riviera’s series of webinar weeks and virtual conferences during November and December 2020 - use this link to access more details and register for these events
