Hyundai Heavy Produces 5,000th Propeller

Hyundai Heavy Industries (HHI) has announced that it held the production ceremony of the 5,000th propeller at its Ulsan factory. The 5,000th propeller measuring 10.6 meters in diameter and 77 tons in weight is scheduled to be installed on a 300,000 DWT VLCC ordered from Athens-based Thenamaris by the end of this month. HHI is not just the only Korean propeller manufacturer capable of churning out large-sized ship propellers heavier than 40 tons, it also has the biggest pie in the global ship propeller market with the market share of 31% as of 2015.

MPS Holds Open House

There was record attendance at the Maritime Propulsion Services BV (MPS) open day on May 23 when more than 200 delegates from shipyards, classification societies and workshops around the world gathered together in Drunen. Apart from the four propellers which were in the workshop for repair, on display were some of the latest developments in quality control as well as repair procedures and technology. These included state of the art nondestructive ultrasonic techniques to inspect either for porosities in bronze castings or weld repairs on propeller blades.

MPR Relocates to Drunen Workshop

Maritime Propeller Repairs (MPR) moved to new premises in Drunen, the township in The Netherlands which is fast becoming a center for propulsion expertise. After Wärtsilä moved production outside The Netherlands the workshops and foundry vacated by the engine builder have developed into becoming the perfect base for a number of propeller specialists. Now located at Drunen are MPR (propeller repair specialists), MPS (propulsion specialists providing service and components), the foundry Gieterij Drunen (one of the largest in Europe)…

Landmark Propeller Delivered to Cal Maritime Campus

On August 26, Cal Maritime will receive and install a massive 18-ton, 18 ft wide brass ship’s propeller which for many years was a landmark of San Francisco’s downtown business district. For several decades, the entrance to the San Francisco office building at 100 Spear Street has been graced by an eye-catching display…..a highly-polished brass ship propeller. This 18-ton piece of “commercial art” was a natural, as the building was home to many offices of ocean carriers serving the West Coast. With industry consolidation, the number of maritime-related offices in the building dwindled.

Wärtsilä to Manufacture Propellers at Zhenjiang CME, China

Wärtsilä has signed an agreement with Zhenjiang CME Ltd, a subsidiary of China State Shipbuilding Corporation (CSSC), to begin the manufacture of controllable pitch propellers (CP propellers) at the two companies' joint venture unit, Wärtsilä CME Zhenjiang Propeller Co Ltd, located in Zhenjiang, Jiangsu province. The inauguration of the new factory and the first deliveries are planned for the second quarter 2011. Wärtsilä CME Zhenjiang Propeller Co Ltd will invest $16.4m in a state-of-the-art facility for manufacturing CP propellers.

Inspection Features Added to PropCad Premium

It is common practice to inspect marine propellers to ensure the manufactured product meets the thickness and pitch specified by the design. PropCad Premium now introduces a tool for propeller builders and manufacturers - Inspection Maps, which allows users to create customized layout templates for measuring blade coordinates, blade thickness and local pitch. HydroComp’s Inspection Maps is a tool to aid in the measurement and inspection of marine propellers during the manufacturing process.

Ultrasonic System Detects Defects in Ships’ Propellers

During the casting of ship propellers small pores and tiny cracks may often arise within the material, which can lead to failure if not repaired. Testing for defects has typically been carried out manually, though it is difficult to achieve consistent and reproducible results with such manual processes. To overcome this problem MPR, in collaboration with a specialized systems office, has developed a new automated ultrasonic system for inspecting marine drive components, such as ship propellers. A small lightweight measurement system is used with a mobile scanning device.

DNV GL White Paper Assesses Alternative Fuels

Classification society DNV GL has issued a new white paper which assesses a range of alternative fuels and technologies. The white paper “Alternative fuels and technologies for greener shipping” examines the price, availability, regulatory challenges and environmental benefits of alternative fuels and technologies, including LNG, LPG, hydrogen, fuel cells, and hybrid and battery technologies, and comparing them to the use of conventional fuel with scrubbers and new low sulphur alternatives.

Creating Patterns with PropCad Premium

HydroComp announced its PropCad software for the geometric modeling of marine propellers has receieved an upgrade. Now, PropCad Premium introduces another powerful feature, the Pattern Corrections tool. HydroComp’s Pattern Corrections tool reduces manipulation of the propeller design within a 3D CAD tool. Pattern Corrections allows users to directly specify machine stock and shrinkage to create machining models, casting patterns and mold geometries. An advantage is that these corrections are applied directly to the propeller parameters…
