China: Dealfeng New Energy completes rotor sail installations on oil tanker, deck carrier

Dealfeng New Energy Technology on Friday (24 November) said it completed the installation of Dealfeng Rotor Sails on a 5,000-tonne class product oil tanker and a 25,000 DWT deck carrier.

This is following a partnership deal between Dealfeng and Haiyue in October 2022.

The delivery of the rotor sails took three months following the approval of drawings by the Classification Society.           

The Dealfeng Rotor Sail is made of lightweight and strong composite material. With a fully automatic Dealfeng control system, they generate forward thrust as the wind causes pressure difference around the rotating rotor while a vessel is sailing. 

“When using this technology, a vessel is expected to achieve a reduction of around 8% fuel and GHG emissions, resulting in the possibility of lowering the power and energy consumption of a vessel’s main engine when wind conditions are favorable, saving fuel and maintaining speed and travel time,” Dealfeng said in a statement. 

As such, the application of Dealfeng Rotor Sail technology enables significant advancements of China’s fleet towards national decarbonisation goals.

Additionally, following the signing of a retrofitting contract with Offshore Oil Engineering Co., Ltd. (COOEC), Dealfeng has installed two sets of Dealfeng rotor sails on a 25,000 DWT deck carrier classed by China Classification Society (CCS). The vessel will be delivered on December 20, 2023 and is expected to achieve fuel savings of around 10%.                                                 

Dealfeng will continue to work towards both the energy saving innovative technologies and the reduction of GHG emissions, helping domestic and international ocean vessels to meet the efficiency and emission-reducing policy requirements of EEDI, EEXI, CII and EU ETS. The technology will also facilitate the maritime industry to early reach carbon peaking and carbon neutrality, achieving green & sustainable development.

Baleària arranges three LNG bunkering operations on same day in Barcelona

Spanish shipping company Baleària on Thursday (15 May) said it broke an all-time record for the supply of liquefied natural gas (LNG) with the bunkering of three of its vessels in the port of Barcelona.

The occasion marked the first time three bunkering operations were carried out on three different ships on the same day at the same port in Spain.

The company said the three vessels were fuelled with a total of 2,320 MWh of LNG by eight tankers. 

Fast ferry Margarita Salas was fuelled by three tankers simultaneously. Ferry Martín i Soler was fuelled by two tankers and ferry Bahama Mama was bunkered by another three tankers also. 

“Our commitment to LNG grew by 184% in 2024. Combined with electric propulsion and other eco-efficiency measures, we have managed to reduce our carbon footprint by almost 10% per passenger,” it said.

Cosco-controlled Piraeus Container Terminal offers biofuel bunkering services

Cosco Shipping Europe, the regional management company of China Cosco Shipping Corporation in the European Region, on Friday (16 May) said biofuel bunkering is now available at Piraeus Container Terminal (PCT) in Greece. 

PCT, a fully controlled subsidiary of Cosco Shipping Ports, has officially introduced biofuel bunkering services for vessels calling at the Port of Piraeus – supporting customers in achieving greener, more sustainable supply chains.

After listening to customer needs, Cosco Shipping (Europe) said PCT swiftly moved into action to re-evaluate legal foundations for biofuel bunkering under ISO 8217:2024 and new Greek regulations.

It added that PCT also partnered with suppliers to provide full-service bunkering options.

Classification society American Bureau of Shipping (ABS) on Thursday (15 May) published its report to bring together the findings of its advanced research into the performance of ammonia on board.

Critical safety questions such as “how does ammonia behave when it leaks in an engine room?” and “how does a cloud of escaped ammonia disperse during bunkering operations?” are addressed in the latest ABS research.

ABS performed computational fluid dynamics (CFD) simulations using advanced tools to quantitatively assess the risks associated with ammonia dispersion in accidental leakage scenarios. 

ABS engineers examined realistic bunkering situations such as ship-to-ship, terminal-to-ship and truck-to-ship, as well as ammonia dispersion from the vessel due to a leakage incident in the engine room.

“This publication provides a comprehensive report of ABS’ efforts to address the challenges and opportunities presented by ammonia as a marine fuel,” said Vassilios Kroustallis, ABS Senior Vice President, Global Business Development.

“Through detailed analysis of ammonia dispersion studies and emergency evacuation protocols, ABS is contributing to the discourse on safe and supportable maritime fuel alternatives, fostering a culture of preparedness and resilience.”

In addition to CFD simulation analysis, ABS leveraged the latest industry best practices and advancements in software and hardware – including acoustic cameras for detecting and visualizing ammonia leakage – to provide a thorough, three-part framework for owners and operators evaluating ammonia as a cleaner fuel source:

  • Proactive regulatory engagement and risk anticipation
  • Development and implementation of a multifaceted safety framework, combining qualitative and quantitative risk assessments
  • Real-time monitoring and optimized emergency response
