In July 2023, GERMAN NAVAL YARDS in the north of Germany had the 600-ton hoisting ropes on their shipbuilding gantry crane – one of the biggest cranes in the country – upgraded by Konecranes Port Services. Because this upgrade replaces an older rope, the safety and reliability of the crane has been preserved for the future. GERMAN NAVAL YARDS is specialized in the building, repair, and maintenance of large and technically complex naval defense ships such as corvettes, frigates, and offshore patrol vessels (OPVs) for customers all over the world. Their Goliath gantry crane helps move assembly blocks to different work areas at every stage of the shipbuilding process. It also assembles sections into a finished ship in the mega dry dock. Wear and tear due to regular use require periodic replacement of the rope and comprehensive hoist maintenance, and they decided that a Konecranes rope upgrade would best suit their needs.
The Goliath crane has two 450-ton hoists for a maximum capacity of 900 tons, and a 600-ton hoist for lighter loads. Konecranes changed the two steel ropes, each with a diameter of 42mm and a length of 1,600m, on the 600-ton hoist. Konecranes also changed the rope pulleys in the upper and lower rope blocks of the hoist, and at the same time, serviced the upper and lower rope sheave blocks of the hoist and the overload device in the upper rope block. The performance of a crane depends on its rope Crane equipment usually lasts for decades. But even the best quality steel rope will eventually wear out as it is subjected to high levels of stress on every lift., Routine and systematic rope replacement is therefore essential to ensure maximum safety, maintain performance, and ultimately, extend the lifetime of the crane. “Spanning 157 meters, our Goliath crane is big enough to reach all the relevant halls and docks in our shipyard and is vital to our continuous workflow. So, it was difficult for us to find a time window to replace the ropes and the right supplier with the tools and expertise for this very specialized equipment,” says Gregor Urbanski, Manager Infrastructure, German Naval Yards Kiel. “Our Goliath is not a Konecranes machine, so they worked with us beforehand to develop the safest and most efficient rope change methodology with minimal downtime. We’re very satisfied with the results.” The first hoist is the main challenge All the hoists on the crane will need new ropes eventually, but to change the ropes on all three at once would cause a lot of downtime. It’s not safe or efficient to change the ropes on only one of the two 450-ton hoists that work in tandem. Therefore, Konecranes opted to make the change on the 600-ton hoist first to ensure the methodology was right. With the success of this rope upgrade, the Kiel shipyard has plans to upgrade the ropes on the other two hoists within the next two years, and Konecranes is at the top of the list of likely providers. “By replacing their crane ropes regularly, the Kiel shipyard demonstrates a long-term commitment to safety, reliability and performance,” says Dittmar Klotz, Site Manager, Konecranes Port Services. “Although we’d replaced the ropes on other cranes at the Kiel shipyard, this was the first time we’d worked on their Goliath crane. The technical requirements of the project underline Konecranes’ expertise, innovative solutions, and long experience in the maintenance of shipbuilding equipment, regardless of make, model or type of crane.”

Attacks on commercial shipping coming from Yemen continued on Monday apparently undeterred by the multi-national coalition led by the United States. While no vessels reported being hit, the Houthi rebels reiterated that they are targeting Israeli shipping interests and ships trading with Israel. MSC Mediterranean Shipping Company later confirmed that one of its vessels was among the ships targeted today. There were two more incidents reported by the UK Maritime Trade Organization (UKMTO) both coming from Yemen aimed at...

An MSC containership due to arrive at the Port of Antwerp was held offshore overnight while the Belgium police investigated a bomb threat associated with the ship. While the police now believe it was a hoax, they are still investigating the report which was eerily similar to another threat almost exactly one year ago. The Belgium Federal Police and FPS Mobility received a bomb threat in the afternoon on December 25 reporting that there would be an explosion when the...

Guam's Piti Channel is going to be narrower for a while, the Coast Guard announced last week, because of a ship that went adrift in a hurricane and fetched up on its shores. On May 24, when Typhoon Mawar swept past Guam, local first responders had their hands full with shoreside impacts. The storm also tore loose a quasi-derelict ship, the vessel Voyager, which had been moored at Apra after the owner abandoned the crew. After the storm, Coast Guard...

Construction of Royal Navy’s five Type 26 frigates in Scotland is facing the risk of further delays due to a planned strike early next year over pay and working conditions. The Type 26 frigate program is grappling with delivery delays and cost overruns, and it has been the subject of criticism, including from the Parliament’s Defense Committee. Next year, the program will sail into further turbulence after electricians, laborers and cable hands employed by CBL Cable Contractors at the BAE Systems Govan and Scotstoun...
