Classification society DNV on Wednesday (6 December) said it has awarded an Approval in Principle (AiP) certificate to China Merchants Jinling Shipyard (Nanjing) Co., Ltd. for its 11,000-CEU capacity LNG-fuelled pure car and truck carrier (PCTC) design at the Marintec China trade fair. 

Recognized as the world's largest PCTC, the 234m long and 40m wide ship will have 14 decks allowing 11,000 car equivalent units (CEUs) to be stored simultaneously, which not only increases efficiency but also reduces the transport cost per vehicle.

By implementing a combination of decarbonization measures, the so-called “Super Large Smart Green 11,000” design will result in a significant reduction in carbon emissions, in line with the stringent requirements of the Energy Efficiency Design Index (EEDI) Phase 3 and NOx Tier III. The PCTC will use LNG as its primary fuel and will be equipped with a 4,200cbm LNG storage tank.

With the assistance of ship designer Deltamarin, the hull line of the vessel has been optimised through numerous CFD calculations and ship model tests. Additional energy-saving features include a stern flow optimization device and an air lubrication system, which effectively minimise resistance and reduce the required propulsion power. The integration of hybrid propulsion systems and solar power further underlines the commitment to reducing energy consumption.

"We expect the market for electric vehicles to continue to grow, driving demand for PCTCs. Scale, energy efficiency and low carbon fuel are key to reducing emissions from the transport of these vessels. As a leading class for car carriers, DNV is honoured to be entrusted with the assessment of this next generation of car carriers and we look forward to working with China Merchants to bring these vessels to the water," said Norbert Kray, Regional Manager Greater China at DNV Maritime.

According to China Merchants, the shipyard is already in discussions with potential customers for the 11,000 CEU PCTC.

Classification society ClassNK on Wednesday (6 December) said it has issued Approvals in Principle (AiPs) for three vehicle carrier designs developed by Shanghai Merchant Ship Design & Research Institute (SDARI) at Marintec China 2023.

The first AiP acknowledged an ammonia ready, LNG dual-fuel vehicle carrier with a capacity of 7,000 CEU, a significant first in China’s independently developed design. SDARI integrated the GTT MARK III Flex containment system for LNG and ammonia fuel storage to maximise the cargo capacity efficiently.

ClassNK also granted AiPs for both methanol dual-fuel and ammonia dual-fuel vehicle carriers, each with a capacity of 10,000 CEU, which is envisioned to lead the development of ultra-large vehicle carriers.

‘SDARI has created these three models exemplify the new generation of green vehicle carriers, adaptable to various alternative fuel options and catering to future market demands,” ClassNK said in a statement. 

“ClassNK has engaged in SDARI’s development projects, and carried out its review in accordance with the relevant standards, including its latest structural rules Part C and Guidelines for Ships Using Alternative Fuels.”

“Marking the AiPs as the milestone, ClassNK is committed to further providing expertise to assist the design firm’s initiative in expanding the industry’s pathway for the transition to decarbonisation.”

Swiss marine power company WinGD on Tuesday (5 December) said it has concluded a four-party agreement underwriting Belgian bulk carrier operator CMB.TECH’s order of X72DF-A ammonia-fuelled engines. 

CSSC Qingdao Beihai Shipbuilding (QBS) and engine builder CSSC Engine Co (CSE) were the other signatories in the joint undertaking to power a series of 210,000 DWT bulk carriers to be delivered from Qingdao through 2025 and 2026.

Following confirmation of the engine order, the agreement advances the project between WinGD and CMB.TECH announced in January to develop the 72-bore ammonia-engine. The close cooperation and shared responsibility reflected in the agreement highlights the groundbreaking nature of the order: the vessels will be the first ammonia-fuelled bulk carriers to be built; the WinGD engine designs will be the first of their size for ammonia; and they will be the first ammonia engines built in China.

CMB.TECH CEO, Alexander Saverys, said: “CMB.TECH sees green ammonia as one of the big solutions to decarbonise long-distance shipping and this order brings to fruition our active commitment to develop this pathway. The gathering of expertise under this agreement will ensure that our first ammonia-fuelled vessels are built and powered in a safe and sustainable way, as well as helping to decarbonise our business and our customers’ logistics.”

WinGD CEO, Dominik Schneiter, said: “Having progressed the engine design and vessel integration concept rapidly with CMB.TECH over the past nine months, enlisting the mutual cooperation of the shipyard and engine builder is a critical next step. As well as safeguarding the successful entry into operation of these innovative engines, this collaboration will also accelerate the spread of ammonia capabilities across key stakeholder groups, placing the whole industry on surer footing as it explores a vital decarbonisation pathway.”

QBS Executive VP, Gu Kechao, said: “CMB.TECH’s decision to have its first ammonia-fuelled vessels built by CSSC Qingdao Beihai Shipbuilding underscores the company’s faith in the quality and value of our work. It also highlights growing acknowledgement of the wider Chinese capability in complex shipbuilding projects. Building among the first ammonia-fuelled vessels in the world will place QBS in a strong position to support further customers with their maritime decarbonisation projects.”

CSE Chief Engineer, Zhang Guangwei, said: “Bringing a new engine design into commercial operation is always the result of strong joint effort between engine and vessel designer, engine builder, shipyard and owner. CSE is honoured to be the first engine builder in China to deliver ammonia-fuelled engines to the maritime market, and to take an early role in what will become a significant market as ammonia fuel is used more widely in shipping.”

WinGD’s X-DF-A engines operate using high-pressure fuel injection with a small portion of pilot fuel, and will have performance and fuel efficiency comparable to the company’s diesel-fuelled X-Engines. No aftertreatment is required for N2O emissions, while selective catalytic reduction is used to ensure Tier III NOx compliance in both ammonia and diesel modes.

Safe operation and maintenance of ammonia-fuelled engines and vessels has been a key undertaking of the project to date. The hazard identification (HAZID) studies, followed by an Approval in Principle from Lloyd's Register of the X-DF-A engine concept were pivotal to WinGD and CMB.TECH verifying that ammonia-fuelled engines built, commissioned and operated to the approved design have equivalent safety to conventionally fuelled engines.
