South Korean shipbuilder Hyundai Heavy Industries has developed a new system for loading and securing containers that it says is both faster and safer with the potential to radically change container shipping. The shipyard reports it has received design approval from both the American Bureau of Shipping and the Liberian Flag administration for its new concept for lashing-free transport of containers.

The challenge of container safety and reducing the loss of boxes overboard gained increased industry attention in 2022 after several high-profile, large losses of containers. The World Shipping Council highlights that there are currently 6,300 ships moving cargo around the globe calculating that approximately 241 million containers are moved annually. Accidents such as the ONE Apus and Maersk Essen late in 2020 drove the average box loss to 3,113 in 2020-2021, far above the previous average which was at nearly 800 boxes annually. 

While the losses overboard draw the most attention, Hyundai highlights the dangers and time spent loading and unloading boxes. No definitive data exists on how many dock workers or crewmembers are injured each year handling and lashing containers in ports around the world. 

“The lashing-free containership is a new concept technology that can fundamentally eliminate lashing-related work, which is a major challenge in the containership industry, and cargo loss,” said Wonho Joo, head of Hyundai Heavy Industries’ technical division.

The lashing-free container ship design developed by Hyundai Heavy Industries uses a new concept device called a “portable bench” (trade name SkyBenchV2) that receives the load of the containers as they are stacked on deck and transfers it to the hull. The Cell Guide, a device that allows the vertical alignment and stacking of containers often 10 or more boxes high, has been extended above the deck. As the container is loaded on deck it is fixed by the expanded cell guide meaning there is no need for the lashing of individual boxes.

The traditional method of loading containers on deck uses a transverse-mounted lashing bridge. Containers are secured to the bridge with twistlocks. This lashing process serves as a support to prevent the containers from moving during operation.

According to Hyundai, the SkyBench structure traps the container on the deck in the cell guide. The system makes it possible to fix the container more stably than the existing lashing bridge structure, which they said will prevent accidents from collapsing or losing the container in rough seas, and also fundamentally preventing safety accidents that occur during lashing work.

“Lashing-free container technology is a groundbreaking technology that increases the safety and efficiency of container ship operation,” said Darren Leskoski, CEO of ABS Far East Asia. 

Hyundai Heavy Industries has completed domestic and foreign patent applications for lashing-free containerships and portable benches.

Norwegian oil major Equinor announced Tuesday that it will be investing $1.3 billion in upgrading its Hammerfest LNG liquefaction plant, located on Norway's far northern Barents Sea coast.  The project will install new onshore gas compression capacity, ensuring enough flow to the plant to keep exports running at current levels through 2030. In addition, electrification will reduce the plant's emissions by about 850,000 tonnes of CO2 annually - about two percent of Norway's total yearly emissions.  "Electrification will allow us to...

The EU's energy ministers have agreed to a European Commission plan to limit natural gas prices, an effort intended to limit escalating bidding wars for LNG cargoes going into next winter. In August 2022, Europe's wholesale gas prices soared to an all-time high of more than €300 per megawatt-hour as EU nations scrambled to fill storage. The surging energy costs have driven up the annual rate of inflation to a damaging 11.5 percent, and Europe has every intention of preventing a...

Robotic hull-cleaning is a burgeoning field, with half a dozen new tech firms competing with traditional diver services in a bid to make shipping more efficient and environmentally friendly. Massachusetts-based Armach Robotics joined the market in March 2022 as a spinoff of marine software company Greensea Systems, and it is expanding its reach using remote operations.  Armach's robotic hull cleaner can be deployed by two people in a harbor, without cranes for handling, and it can be operated from company headquarters....

Spanish renewables developer Avangrid has announced that it is seeking to walk away from the current contracts for the Commonwealth Wind project planned for Massachusetts, saying that after months of negotiations the project is not economically viable in its current form. After two months of back and forth with the state and regulators, the company made a filing on December 16 proposing that the project be rebid in a competitive solicitation scheduled for April 2023. “Despite unprecedented challenges in the...
