An order for a set of nitrogen systems to be installed on an LNG-powered cruise ship has been placed with Maritime Protection, a brand of global survival technology solutions supplier Survitec, as reported by Offshore Energy.
Adoption of Inert Gas(IG) systems
Two nitrogen generators, feed-air compressors, valves, and control cabinets are included in Survitec’s scope of supply.
The business praised the deal as essential and welcomed the chance to assist the cruise sector in switching to alternative fuels, in particular by providing expertise on the adoption of Inert Gas (IG) systems as a crucial safety measure.
According to Survitec, the 51,950gt newbuild, which is expected to be delivered in 2025, is the first cruise ship for the unnamed Japanese owner to be built in Europe; a second ship is also an option.
Managing Director of Fire Systems at Survitec, Mark Clegg, stated: “This order establishes Survitec as a reliable partner for the cruise sector. The passenger ship industry has only recently started to investigate the technology, even though our IG systems have already become widely used in other ship types.
From our perspective, a cruise ship is the same as any other vessel. But, as more passenger ships switch to greener fuels, this most recent contract victory allows us to grow our market. As a result, we anticipate receiving additional orders.
Alternate fuels
A total of 25 LNG-fueled cruise ships are expected to enter the worldwide fleet over the next five years, according to Survitec, and in that context, the company noted that engines using LNG, ammonia, and methanol, in particular, need an N2 system for safety reasons.
“Nitrogen is utilised to purge the fuel gas system before and after engine start-up or when any maintenance work is done out,” explained Rune Moseidjord, sales manager at Maritime Protection. It produces a setting that is safer and more stable.
Every passenger ship using alternative fuels must have a low-maintenance, dependable, and reasonably priced N2 system. Our IG systems have the advantage that each one is custom-engineered to match the needs of each ship.
The nitrogen systems from Maritime Protection are simple to install and completely automatic with PLC control, according to Survitec. Also, the brand’s remote help programme, which enables support services like technical support and troubleshooting to be delivered remotely, can be used to support the systems.
LNG bunkering
On the acceptability of LNG bunkering in the cruise industry, David Welch, Shipyard Sales Manager (World Cruise), Survitec, stated: “We’re witnessing an increase in passenger ship operators specifying vessels with engines capable of running on LNG. But, shipowners must take the fire danger into account. The industry is promoting the green agenda since several destinations are now restricting the size and number of ships burning heavy fuel oil.”
“These alternate fuels can have serious consequences in the event of a fire. To prevent fires from spreading, inert gas systems must be used, along with monitoring of gas pressures and temperatures for extremely early detection.”
“Our Head Start project was created with this in mind: we support ship owners and work with them from the earliest designs to scope their requirements and design a complete fire protection and safety management solution. We can assist them in preparing their boat so that they can sail safely for a very long period.”
Survitec added that it had received orders from shipyards in Turkey and Poland for nitrogen IG systems to be used on cruise and ropax ships using LNG as a marine fuel.
Survitec’s fire fighting system and safety gear on board Yara Birkeland, the first completely autonomous containership in the world, successfully finished its first annual servicing before the 3200 dwt ship’s first loaded journey in 2022.
