GTS Secures Engines with Common-Rail, Methanol-Ready Features for Tanker Quartet

Fujian Mawei Shipbuilding and Xiamen Shipbuilding Industry, both prominent shipbuilders in China, have secured an order for four MAN 10L32/44CR main engines, marking a significant development in collaboration with the Bremen-based shipping company GTS. The order encompasses the construction of four 41,000 deadweight tonnage (dwt) tanker newbuilds designed by Swedish Fartygskonstruktioner AB, with Xiamen Shipbuilding set to commence construction and delivery scheduled from mid-2025 onwards. Notably, the order includes options for an additional two vessels.

The chosen engines, integral to MAN's common-rail engine series, are versatile, capable of utilizing conventional fuels such as Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Marine Gas Oil (MGO), as well as biodiesel options like Hydrotreated Vegetable Oil (HVO) and/or Fatty Acid Methyl Ester (FAME). Furthermore, these engines are designed with the flexibility for retrofitting to methanol operation, aligning with evolving environmental considerations in the maritime industry.

Each MAN 10L32/44CR main engine will exhibit a robust power output of 600 kW per cylinder and will be responsible for propelling a MAN Alpha VBS1260 CP propeller through a Flender GUCK-1560 gearbox. This strategic combination aims to optimize vessel performance, ensuring alignment with the International Maritime Organization's (IMO) Energy Efficiency Design Index (EEDI) regulations.

Importantly, these engines integrate seamlessly with MAN Energy Solutions' low-pressure selective catalytic reduction (SCR) system, showcasing NOx-reduction rates of up to 90%. Christian Kamm, MAN Europe sales manager, emphasized the high efficiency maintained by the MAN 32/44CR engine at all times, without incurring any fuel penalty or derating when operating the SCR system, particularly with Heavy Fuel Oil (HFO). He highlighted the lower operating temperature of MAN SCR solutions, ensuring compliance with the most stringent emissions standards.

The SaCoS 5000 engine automation system embedded in the 32/44CR engines enhances cybersecurity compliance and facilitates remote technical support. This feature reflects MAN's commitment to advanced technology and digital solutions to meet contemporary industry demands.

In addition to the main engines, each vessel will incorporate MAN auxiliary engines, featuring two 8L23/30H Mk2 900 rpm and one 6L23/30H Mk2 720 rpm gensets. The engines will be manufactured in China by MAN licensee CSSC Marine Power Co., Ltd.

Notably, the ships will be equipped with water-lubricated stern tubes, a testament to MAN's dedication to environmental sustainability. This design choice ensures the elimination of any 'oil-to-water interface,' thereby mitigating the risk of oil leaks.

In conclusion, the collaboration between Fujian Mawei Shipbuilding, Xiamen Shipbuilding Industry, and GTS, coupled with the selection of MAN 10L32/44CR main engines, signifies a significant stride towards innovative and environmentally conscious solutions in the maritime sector. The integration of cutting-edge technologies and the adherence to stringent environmental standards underscore the commitment of all parties involved to shaping a more sustainable future for maritime transportation.
