YM Celebrity leads the new 2,940TEU cellular series.

‘Smart ship’ technologies permeate a new generation of 2,940TEU container vessels built in Taiwan for Yang Ming Marine Transport Corp, writes David Tinsley.

The 210-metre YM Celebrity provided the service debut for the 10-ship series in June, and has since been followed by YM Continent and YM Credential. Contractor CSBC’s Kaohsiung yard is due to complete the programme with the handover of the 10th newbuild in September 2021.

The design has been developed to raise Yang Ming Line’s competitiveness and capabilities in intra-Asia trade, and represents a major advance in both economic performance and environmental level relative to previous tonnage. YM Celebrity and YM Continent have been assigned to a Japan/Taiwan/Hong Kong/China service, while the newly-commissioned YM Credential is to be deployed between Vietnam, Taiwan and Hong Kong.

Each of the 10 vessels has been specified to meet Smart Ship notational criteria of various classification societies. In the case of series leader YM Celebrity, the standards applied are those of American Bureau of Shipping (ABS).

The company claims that the combination of machinery, hull lines, and shipboard systems means that the type promises a reduction of about 33% in fuel consumption compared to “the previous vessels”.

CSBC’s proprietary Sea Sword Bow concept has been adopted, to provide better seakeeping and hydrodynamic efficiency in all conditions relative to more conventional bulbous bow forms. The cellular hold section is complemented by a lattice of weatherdeck lashing bridges, enhancing both cargo handling turnaround times and cargo security at sea, with further protection afforded by a substantial wavebreak on the raised forecastle. Electrical sockets are provided for 353 reefer boxes.

YM Celebrity is powered by a seven-cylinder S70ME-C10.5 diesel produced in South Korea by MAN licensee HSD Engine Co, and rated for a maximum continuous output of 20,500kW at 91rpm. With direct drive to a Nakashima fixed pitch propeller, the installation ensures a design speed of 21 knots. The troika of 1,900kW generators also derives from Korea, being HFC7 models from the Hyundai Electric & Energy Systems range.

Built under the ABS Enhanced Hull Construction Monitoring Program, YM Celebrity carries the society’s SMART notations, as does YM Continent and three of the newbuilds to come (YM Certainty, YM Credibility and YM Continuity). The SmartINF (data infrastructure for smart function implementation) and Smart SHM (structural health monitoring) descriptions denote that the recipient vessels are equipped for ‘big data’ acquisition and ‘cloud’ transmission, enabling structural endurance monitoring and future structural health awareness through ABS’ customised analysis program.

Three of the series under construction (YM Centennial, YM Capacity and YM Cooperation) will be accredited with DNV GL’s SmartShip descriptive notations. The SmartShip OE (operating enhancement) and PE (performance enhancement) terms to be applied signify the use of advanced technologies to achieve, for instance, improved container load flexibility with route-specific container stowage and fuel saving through trim optimisation.

Third-of-class YM Credential has been specified with the SMARTSHIP (Machinery 1) notation of Bureau Veritas, relating to the use of an integrated computer-based system for the control and monitoring of automated installations in periodically unattended machinery spaces. The same arrangements will apply to the forthcoming YM Constancy.

In addition, seven of the vessels in the series are being certified by Taiwan’s own, non-IACS society CR (formerly the China Corporation Register of Shipping) to confirm smart characteristics. The Smartship H, Et and I notations reflect, respectively, smart hull structural health estimation, smart energy efficiency/trim optimisation, and smart integration platform. The recipients of the CR endorsements are YM Continent and YM Credential, to be followed by YM Centennial, YM Capacity, YM Certainty, YM Credibility, and YM Continuity.
