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)…

Robot Lasers Prolong Engine Pistons’ Lifespan

New robotized laser cladding technology aims to revolutionize the reconditioning of large bore pistons in two-stroke engines. A new reconditioning process from Wärtsilä Services’ maintenance and repair services business Line QuantiServ minimises welding, causes less thermal shock to the base material and replaces the old chromium layer’s galvanic application. “In addition to its environmental efficiency, the new coating extends the piston head’s lifespan and time between overhauls (TBO), compared to conventional chromium layers.

Tech File: Propelling Hybrid Electric Solutions

Growing interest in hybrid-electric power systems is expanding the search for new propulsion and energy-storage systems in the workboat sector, where compliance with emerging environmental regulations and a relentless pursuit of operational efficiency are driving change. To meet demands for cleaner more efficient power, owners are examining the potential for less conventional methods of energy generation and storage – such as fuel cells, lithium-ion batteries, super-capacitors, flywheels, wind and solar – to propel their vessels.

It’s Electric: Charging Asia’s First E-ferry

Innovative charging technologies connect Asia’s first e-ferry to electrical power, eliminating emissions and dramatically reducing operating costs. The retrofitted passenger ferry, which operates between the island of Cijian and the port of Kaohsiung in Taiwan and that entered service last year, is fully electrically powered. This follows the introduction of a hybrid ferry earlier in 2017. The charging solution was supplied by Swiss based engineering firm Cavotec, who said the technology ensures safe, fast and efficient connection of the ferry to electrical power at the Kaohsiung berth.

Cal Maritime Installs Massive Ship Propeller Display

On August 26 Cal Maritime received and installed 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.

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.
