Sanmar has pleasure in drawing to your attention the following press release issued by Caterpillar following a signing ceremony which took place at the New Orleans Workboat Show. Sanmar’s Design Manager, Özer İlhan attended the event.
Hamburg, Germany – Caterpillar Marine is pleased to announce collaboration with Sanmar Shipyards in Istanbul, Turkey to build an innovative tugboat with a hydraulic hybrid propulsion system. The Cat Marine Advanced Variable Drive™ (AVD™) is a patented system leveraging Caterpillar’s extensive experience with integrated power systems technology. Sanmar is the largest tug builder in Turkey with over 40 years of experience and known as a market leader at the forefront of the tug building industry.
The Sanmar hydraulic hybrid tug will be a Robert Allan Ltd. designed RAmparts 2400SX harbour tug [Sanmar’s popular Bogacay series] incorporating an integrated Caterpillar AVD™ system.
The AVD™ system provides significant improvements in both fuel efficiency and vessel performance through a fully integrated hydro-mechanical propulsion system.
“Different from a typical Power Take In (PTI) solution, the AVD™ incorporates a planetary gear set allowing seamless clutch engagement of main engines, auxiliary engines, or both to provide a scalable power installation to meet any customer need in terms of maximum vessel speed, power, or bollard pull,” said Nathan Kelly, Caterpillar Marine Product Definition Engineer. “This also allows propeller speed independent of engine speed so optimal engine efficiency can be achieved leading to fuel savings of fifteen to twenty percent. Basically, all the benefits of a variable speed Diesel Electric Propulsion (DEP) system at a fraction of the cost and size,” said Kelly.
