Survitec reports significant increase in orders for IG systems following high orders for LNG vessels

Engines running on LNG would need to be fitted with an inert gas system to prevent the build-up of highly flammable gasses, according to Survitec’s Maritime Protection brand.

Survitec’s Maritime Protection brand recently said it has registered a significant increase in orders for Inert Gas (IG) systems over the past two years, following a surge in orders for newbuild vessels with LNG-burning engines.

The increase is partly attributed to the global shipping industry seeking to meet decarbonisation targets by moving away from high polluting heavy fuel oil (HFO) towards alternative, cleaner marine fuels.

About 35% of the current world order book accounts for dual-fuelled and gas ships running on either a combination of liquefied natural gas (LNG) and conventional fuel or LNG alone. These engines need to be fitted with an inert gas system to prevent the build-up of highly flammable gasses.

Bernt Øhrn, General Manager, Maritime Protection, explained: “If the ship doesn’t have any oil or gas cargo tanks, which require a fixed CO2-based system to deal with the higher volume, a small N2 inert gas system is needed to make the fuel system safe.”

Demand for natural gas as a marine fuel is expected to continue over the next twenty years, with the industry viewing the energy source as a vital step towards decarbonisation.

“This is demonstrable in the increased orders for IG,” said Øhrn. “We are seeing a significant push for alternatively fuelled newbuilds capable of handling the new emissions requirements. But we also see an increase in engine conversions and retrofits, with shipowners converting topsides to accommodate LNG fuel tanks.

“Although LNG only accounts for one-in-three newbuilds, shipowners of all types are beginning to see the dual-fuel or gas engine as the way forward.”

According to Øhrn, analysts predict a 25% increase in orders for dual-fuelled ships in 2023, increasing to 50% by 2025.

“With the need to further reduce the impact of ship operations on the marine environment, the speed of technological development will see the adoption of other alternative fuels, particularly ammonia and hydrogen,” said Øhrn, adding that Survitec is involved in several industry and university-based research projects investigating ways to make such fuels safe.

Øhrn predicts ammonia will become increasingly important but will require much larger fuel tanks, while the safety of a hydrogen-fuelled ship is likely to prove a challenge.

“High rates of hydrogen mixing with oxygen can be dangerous. We are developing ways of inerting the exhaust side of a hydrogen fuel cell outside the ship. It may not be possible to use nitrogen as this could evaporate on contact with the colder hydrogen, so helium may be the only inert gas we can use. The problem with helium is it’s a scarce resource and expensive.”

Whatever the fuel of the future fleet, Survitec is supporting the industry on its sustainable maritime journey. Survitec’s new Head Start initiative was created with this in mind to support vessel owners and operators navigate these new challenges safely.

“We recognise the opportunities and challenges the industry will face in the coming years as significantly increasing numbers of vessels will be built or retrofitted to run on alternative fuels,” said Øhrn. “We are designing solutions to ensure operations remain safe no matter the fuel.”

Ammonia

Singapore: EMA, MPA shortlist two consortia for ammonia power generation and bunkering

Chosen consortia are Keppel’s Infrastructure Division and Sembcorp-SLNG, and the bunkering players in these consortia are Itochu Corporation, NYK Line and Sumitomo Corporation.

RESIZED bunker tanker singapore

The Energy Market Authority (EMA) and the Maritime and Port Authority of Singapore (MPA) on Thursday (25 July) said they have shortlisted two consortia that will proceed to the next round of evaluations of proposals to provide a low- or zero-carbon ammonia solution on Jurong Island for power generation and bunkering. 

The two consortia were selected from a total of six that were earlier shortlisted in 2023 to participate in a restricted Request for Proposal (RFP), following an Expression of Interest (EOI) called in 2022. The bids were assessed based on the technical, safety and commercial aspects of their proposals. 

The two consortium leads are Keppel’s Infrastructure Division and Sembcorp-SLNG, and the bunkering players in these consortia are Itochu Corporation, Nippon Yusen Kabushiki Kaisha (NYK Line) and Sumitomo Corporation. The two consortia will proceed to conduct engineering, safety and emergency response studies for the proposed Project.

At the next phase, we will select one of the two bidders as the lead developer of the project. The lead developer will develop the end-to-end ammonia solution comprising (i) generating 55 to 65 MW of electricity from imported low- or zero-carbon ammonia via direct combustion in a Combined Cycle Gas Turbine; and (ii) facilitating ammonia bunkering at a capacity of at least 0.1 million tons per annum (MTPA), starting with shore-to-ship bunkering followed by ship-to-ship bunkering. 

Given the nascency of the technology and global supply chains, the Government will work closely with the appointed lead developer to implement the Project. We aim to announce the lead developer by Q1 2025.

The project is part of Singapore’s National Hydrogen Strategy launched in 2022, which outlines Singapore’s approach to develop low-carbon hydrogen as a major decarbonisation pathway as part of the nation’s commitment to achieve net zero emissions by 2050.

A key thrust of this strategy is to experiment with the use of advanced hydrogen technologies that are on the cusp of commercial readiness. Ammonia is currently one of the most technologically-ready hydrogen carriers with an established international supply chain for industrial use.

“If successful, the project will position Singapore as one of the first countries in the world to deploy a direct ammonia combustion power plant and support the development of ammonia bunkering for international shipping, EMA and MPA said.

“This will help to unlock the potential of low-carbon ammonia as a low-carbon fuel.”

China: River-sea LNG bunkering vessel named and delivered in Shanghai

China’s river-to-sea LNG bunkering vessel, which was built locally, was named and delivered in Shanghai on Monday (19 July), according to the Shanghai Association of Shipbuilding Industry (SASIC). 

The 14,000 cubic metre (cbm) ship, Huaihe Nengyuan Qihang, was independently developed, designed and built by Hudong-Zhonghua Shipbuilding (Group) Co., Ltd for Huaihe Energy Holding Group as part of China’s "Gasification of the Yangtze River” project.

The ship is capable of travelling through the Nanjing Yangtze River Bridge all year round and has been dubbed a “Customised Yangtze River” LNG refuelling and transportation ship.

The ship is equipped with the B-type LNG containment system independently developed by Hudong-Zhonghua and authorised by a national patent.

According to SASIC, this was the first time such a system has been applied to a domestic LNG  refuelling and transportation ship, marking a major breakthrough in the B-type LNG containment system developed by China with independent intellectual property rights.

Singapore: EPS takes delivery of LNG dual-fuel bulker “Mount Ossa”

Singapore-based shipping firm Eastern Pacific Shipping (EPS) on Wednesday (24 July) said the last vessel in its series of six 210,000 dwt dual-fuel LNG Newcastlemaxes chartered to Rio Tinto, was successfully delivered.

The delivery of Mount Ossa marked the 21st vessel being delivered by New Times Shipbuilding to EPS.

“Despite global challenges, Rio Tinto and EPS have shown unparalleled resilience and a strong commitment to decarbonize shipping,” it said in a social media post.

“Over the past three years, these LNG-powered vessels have proven to be a sustainable choice, emitting 30% less than their conventional counterparts. We have successfully completed over 200 LNG bunkering operations, significantly reducing emissions across our fleet.”

“We celebrate our strong partnership with New Times Shipbuilding on this 21st milestone delivery to the EPS fleet, grateful to have 43 world-class vessels built and delivered, including those on order from New Times, which means we are only halfway through our esteemed collaboration.”
