The prelude is supposed to locate off shore Northern Australia , its to avoid a mountain of regulations , local taxes , hassles with the land rights and quite expensive labor costs ,
being able to be re located elsewhere quickly is interesting , we've had a self contained floating hotel
last time I heard about it it was in Saigon , they needed a luxury hotel and this one came all ready

on the Frigg field off Norway , like two hundred others , I was commuting twice a day from one platform to another , one miles away .
Later , the "live- in " platform was brought closer , a footbridge was connected , that was much better

helicopters and the oil industry have a long , intense and sometimes tragic history together

What I was actually looking forward to, was a discussion of how appropriate this technology was.

I have no doubt, fleets of like vessels will be effective at collecting gas from the ocean floor, concentrating it, and sending it to remote markets to burn. I have no doubt, the overall energy output will only release about half the carbon dioxide that would be spewed by coal plants producing the same amount of power.

No doubt, it will also leak a fair amount of methane directly into the atmosphere from the production wells themselves. Since methane is an even more potent greenhouse gas than carbon dioxide, hundreds of these Southern Hemisphere gas production vessels, unencumbered by any form of environmental regulation because they do not produce anything within the waters regulated by any country, may well warm the Southern Hemisphere even more than burning such huge amounts of gas warms the Northern Hemisphere energy markets.

Here is the Kewaunee Nuclear Generating Station, which I recently encountered while scouting the Lake Michigan shoreline for a potential home site:

This power station has a perfect operating record, but was closed in 2013 because it could not compete with the cost of electricity generated from fracked natural gas.

Some of you no doubt approve. However we replaced electrical power generated by nuclear energy (15% of the carbon dioxide produced by coal) with natural gas (50% of the carbon dioxide produced by burning coal). Thus carbon dioxide emitted by electricity generation increased 333%. Multiply that by all the idled nuclear stations in the USA, and this country has gouged a large wound into the globe - as did both Germany and Japan, when they both stopped using nukes. NONE of these three large energy consuming countries replaced nuclear with renewable energy, gas and coal pretty much made up the difference.

I cannot help thinking that this was not a good change.

Perhaps the Mods could merge these two threads.

Please allow me to ruffle some feathers, as I continue to ignore the panic-mongering about oil & gas running out.

Expansion of oil & gas infrastructure continues, regardless of any narrative to the contrary.

So let's have a look at Norway, and what they are planning to do to increase their exports of their natural gas resources in the Arctic.

Natural gas pipelines are generally cheaper than conversion to LNG.

This article does a good job in breaking down the numbers for the costs of natural gas pipeline expansion vs. LNG for Norway's Arctic natural gas resources.

=======================================

Rystad Energy: Gassco’s pipeline option far cheaper than LNG alternative

$this->bbcode_second_pass_quote('', 'A') Rystad Energy cost analysis of the Norwegian pipeline operator Gassco’s proposed options to export the country’s Arctic natural gas resources, shows that the expansion of Norway’s pipeline infrastructure is a more viable solution compared to boosting the capacity of the existing Hammerfest liquefied natural gas (LNG) plant. However, at least 40 billion m3 of additional resources from new discoveries would be needed in order to justify such an initiative.

At present, the Hammerfest LNG terminal only has 7.4 billion m3/y of LNG export capacity, and this limit is expected to be reached in 2026 as gas production in the region will exceed export capacity. The terminal was built to accommodate the gas discoveries of the 1980s, but since then new discoveries have added up. Rystad Energy estimates the remaining discovered natural gas resources in the Barents Sea at around 90 billion m3.

If Norway’s gas resources in the Barents are to be further developed and exploited, there are two main options to reach markets: either build a major new gas pipeline as a link to existing infrastructure in the Norwegian Sea or increase LNG capacity at Hammerfest. If export capacity limits are not increased, projects will have to be phased so as to fill pipeline capacity as it becomes available, destroying substantial value. ...


... The winner:

A new pipeline export route wins out in terms of offering the lowest cost, on a per unit basis, for additional gas export volumes.

Assuming the pipeline were to utilise the simpler processing or even the more expensive expansion of an existing processing plant, this project would still realise gas costs of around US$1 per million Btu, a lower cost export solution with any capacity up to 30 million cmd. This would allow for a further 5 million cmd of yet-to-be discovered and developed resources to be sent through the conduit.

Greetings, Mr. Kirkman.
Always great to see informative contributions and I hope that you are able to continue with your excellent data postings on this site.

As Groningen's 1 Bcfd contributions will cease after 2 more winters, it will be interesting to see how all this market jockeying will pan out.
France's nuclear plants expect a curtailed output this fall, raising concerns about electricity pricing this coming winter.
Adequate supply of natty - whether piped or in LNG form - may assume greater attention amongst the European markets when/if the people wake up one day and it is simply not there.
Best regards to you and hope things are going well.
