‘Clamp on Blade’ propeller receives Special Mention at the DAME Awards

Teignbridge Propellers Int. Ltd. is thrilled to announce that its innovative Clamp on Blade propeller has been awarded a special mention at the DAME awards at the Marine Equipment Trade Show in Amsterdam.

The Teignbridge Clamp on Blade (CoB) propeller is an innovative, UK patented and worldwide patents pending, replaceable blade propeller designed for operational flexibility and maximum hydrodynamic efficiency. The CoB propeller has been developed in partnership with the Energy Technologies institute as one part of a 3-year, multi-million pound development and demonstration project focused on improving the efficiency of ship propellers with the aim of reducing fuel consumption and associated greenhouse gas emissions. David Duncan, the Managing Director, said “We are very pleased that our hard work has paid off, to be selected out of 59 entries to receive a special mention, it means so much. We look forward to the continued development of propulsion efficiency.”
With a hub diameter ratio typically only 5% higher than a mono-bloc, fixed pitch propeller, the patented blade clamping design represents the lowest hub to diameter ratio on the market ensuring that as much of the propeller disc area as possible is put to work generating thrust. Unlike alternative, radially bolted solutions, the CoB propeller hydrodynamic efficiency is further improved by minimising the number of bolt heads present on the hub surface resulting in improved flow over the hub.

The Jury at the DAME awards commented: “Teignbridge undertook an extensive design process for its Clamp on Blade propeller. CNC machining ensures exact replica spare blades of the original. The mechanism within the slim hub that permits blade changes is also commendable in its simplicity.”

The component parts of the propeller are fully machined to ensure dimensional accuracy in the initial assembly and interchangeability of replacement blades. This means that operators can carry a single, replacement blade instead of a full replacement propeller, freeing up deck space and significantly improving logistics associated with moving and lifting the lighter, spare components.
