DNV awards TADC to China’s CMES-Tech for new 35m tilting rotorsail design

Classification society DNV on Wednesday (3 December) said it has granted a Type Approval Design Certificate (TADC) to CSSC Shanghai Marine Energy Saving Technology Co., Ltd. (CMES-Tech) for its new 5m × 35m Tilting Type Wind Assisted Rotor System. 

This is the first domestically developed rotor sail system in China to achieve this recognition under DNV’s WAPS rules (ST-0511). 

With this certification, the classification society said the system is confirmed ready for installation on DNV classed commercial vessels and marks a major milestone for China’s green-shipping technology industry.

As shipping faces mounting pressure from fuel costs and emissions regulations, the demand for reliable and efficient wind-assisted propulsion systems is rising globally. Recent years have seen a growing number of WAPS solutions certified by DNV, including fixed or tiltable rotor, wingsail, and suction sail systems from providers around the world.

The CMES-Tech tiltable rotor system features a retractable and adjustable design, enabling the rotor to adapt to varying draft and clearance conditions, and retract during cargo operations to avoid interference with deck/hatch operations or port infrastructure. The system also integrates intelligent sensing and automatic control to adjust rotor operation based on real-time wind conditions, maximizing wind propulsion efficiency, while maintaining safety.

Dr. Huang Guofu, General Manager of CMES-Tech, said: “Receiving the DNV TADC is a landmark for China’s green-shipping industry and a strong validation of our design’s maturity, structural integrity and operational practicality. It demonstrates that our 5 m × 35 m tilting rotor design meets the highest classification and validates our commitment to driving maritime efficiency. We look forward to working with DNV as we continue to innovate and deliver solutions that can deliver economic and environmental value to shipowners worldwide.”

As part of the TADC process, DNV’s classification experts reviewed all mechanical, structural, and electrical design documentation, and assessed the system’s suitability for shipboard application under realistic operational and environmental conditions. The review confirmed that the design of the CMES-Tech system meets the requirements of DNV’s WAPS technical standard (ST-0511).

Mr. Chen Keng, DNV Vice President and Area Manager China South, said: “With increasing demand for energy-efficient and emission-reduction solutions, WAPS technologies offer immediate, tangible benefits to shipowners. 

“The awarding of this TADC to CMES-Tech means we add another option to the growing portfolio of WAPS systems that have been assessed to the industry’s leading rule set, building further confidence in their readiness for real-world use. We congratulate CMES-Tech on this achievement, which underscores our strong collaboration on enabling the broader deployment new energy enhancing technologies.”

The rotor sail prototype has also successfully passed a rigorous 120% overload structural test, demonstrating its robustness under extreme load conditions. Looking ahead, CMES-Tech will proceed with detailed installation planning and sea-trials to validate the in-service performance of the new system.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
