Technology firm Wärtsilä Tuesday celebrated the 100th order of its fuel gas supply system, also known as LNGPac, with the latest order from Singapore based AET Tankers to install LNGPac systems in its two new shuttle tankers using Wärtsilä 34DF dual-fuel auxiliary engines running primarily on liquefied natural gas (LNG) fuel.

The Wärtsilä LNGPac was first introduced in 2009 and has played an important role in establishing the viability of LNG as a marine fuel.

The system comprises a bunkering station, the LNG fuel tank and related process equipment, as well as the control and monitoring system. The LNGPac fuel system can be offered as a standalone product, or as part of a complete propulsion system.

“A major reason for the global acceptance of LNG fuel for shipping is that Wärtsilä realised at an early stage that more than just a dual-fuel engine and a stand-alone LNG system was needed,” says Mathias Jansson, General Manager, Fuel Gas Supply Systems, Wärtsilä Marine Solutions.

“LNG fuelled ships require a complete fuel handling system, and the innovative LNGPac system very successfully meets this requirement.”

According to Wärtsilä, the first LNGPac installation was for the chemical tanker Bit Viking owned by Swedish operator Tarbit. The vessel was converted for LNG fuel operation in 2011, and its success paved the way for the rapid acceptance of the Wärtsilä solution.

Since the original introduction of the LNGPac, Wärtsilä has continued to develop the system. The company has, for example, pioneered the utilisation of the cold energy stored in LNG by using it to cool the onboard HVAC and galley system.

Another achievement has been the development of a compact LNGPac with an integrated gas valve unit (GVU) and airlock. The inline tank connection space for single shell tanks has been developed, as has been a dedicated LNG fuel pump based on the well-proven deepwell pump technology.

Today the LNGPac is installed on some 12 or more different types of vessel, including passenger ferries, tugs, dredgers and offshore vessels.

DNV awards AiP to China Merchants Jinling Shipyard for world’s largest PCTC design

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.

China: ClassNK AiP issued to SDARI for three vehicle carrier designs with alternative fuel propulsion

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.”

KPI OceanConnect, Titan, and SFL join forces on milestone LNG bunkering operation

KPI OceanConnect, on Tuesday (5 December) said it has collaborated with Titan Clean Fuels, and shipowner SFL to successfully complete the company’s first LNG bunkering operation for the newly built car carrier, Emden, taking place in the Port of Emden.

Michael Schaap, Commercial Director, Titan, said: “Demand for LNG is rising as it is becoming a mainstream fuel since it is widely available today and enables ship operators to reduce emissions now. This operation highlights our commitment to consistently serve our clients as a trustworthy provider of cleaner fuels and we look forward to continuing to enhance our LNG and bio-LNG bunkering capabilities as the market grows, enabling us to supply (bio)LNG to even larger vessels.”

Jesper Sørensen, Global Head of Alternative Fuels and Carbon Markets, KPI OceanConnect, said: "We are incredibly proud of the trust displayed in us by a forward-thinking owner such as SFL, and delighted to have partnered with a world-class supplier, Titan, to complete this supply of 3,000 CBM of LNG. This significant achievement underscores KPI OceanConnect's unwavering commitment to supporting the growing role of LNG in the shipping industry's energy transition. The operation marks our inaugural LNG deal for a car carrier – testament to the company's dedication to advancing sustainability through partnerships up and down the supply chain.”

“Partnership plays a key role, not just in the development of future alternative fuels, but also in the delivery of those already available in the market. Cooperation between fuel providers and buyers in the market is essential to supporting capacity growth and, crucially, immediately reducing greenhouse gas emissions from the industry.”
