How Does Offshore Stainless Steel Pipeline Installation Work? By yaang.com

Laying pipe on the seafloor can pose a number of challenges, especially if the water is deep. There are three main ways that subsea stainless steel pipe is laid -- S-lay, J-lay and tow-in -- and the pipelay vessel is integral to the success of the installation.
​
Buoyancy affects the pipelay process, both in positive and negative ways. In the water, the stainless steel pipe weighs less if it is filled with air, which puts less stress on the pipelay barge. But once in place on the sea bed, the stainless steel pipe requires a downward force to remain in place. This can be provided by the weight of the oil passing through the Stainless Steel Pipeline, but gas does not weigh enough to keep the stainless steel pipe from drifting across the seafloor. In shallow-water scenarios, concrete is poured over the stainless steel pipe to keep it in place, while in deepwater situations, the amount of insulation and the thickness required to ward of hydrostatic pressure is usually enough to keep the line in place.

Undersea Stainless Steel Pipeline History and Uses By yaang.com

The first major undersea stainless steel pipeline was built during World War II. Nicknamed Operation PLUTO (Pipe Line Under The Ocean), this stainless steel pipeline stretched 70 miles across the English Channel, connecting the Isle of Wight with the coast of France. The construction required 46 tons of building materials per mile. Operation PLUTO was intended to provide a safe way to transport fuel to Allied tankers. To keep the stainless steel pipeline secret, pumping stations along the route were disguised as garages and other inconspicuous buildings.

Use of Subsea Stainless Steel Pipeline By yaang.com

​

One of the first major subsea stainless steel pipeline was built between Great Britain’s Isle of Wight and the coast of France during World War II and since then, their use has expanded exponentially.

Today, undersea stainless steel pipes are mostly used to move oil and gas. Companies mine both from the ocean floor and the stainless steel pipes are used to bring these fossil fuels ashore. After oil or gas has been refined, different stainless steel pipelines are used to move oil, or the liquefied natural gas, to fuel tankers.

Pipe to bring water to Phuket from mainland takes another step toward reality

A stainless steel pipe that would supply Phuket with water from the mainland came a step closer to reality yesterday with the conclusion of the feasibility study and second public hearing.

“With the feasibility study completed, the next step is to run an Environmental Impact Assessment (EIA) and get approval, then we can determine the budget,” said Chamnian Muangchan, director of the Water Resource Department of Provincial Waterworks Authority (PWA) Head Office.

“The 182-kilometer stainless steel pipe would transport water from the Ratchaprapa Dam in Surat Thani to Phuket, Phang Nga and Krabi and is needed because the growing number of tourists in the provinces has increased the demand for water,” said PWA Deputy Governor Somkiat Piriyagolgul last November (story here).

The rate of increase in Phuket is about seven per cent per year, which means that in 30 years a supply of 140 million cubic meters of water will be needed, explained Mr Chamnian.

“Even if Phuket gets a lot of rain, we won’t be able to store that much water, because land prices are too high to invest in enough reservoirs,” he said.

Three options were presented for the stainless steel pipeline at the first public hearing: 

1. Having Surat Thani supply untreated water to Phuket, Phang Nga and Krabi

2. Having Surat Thani supply treated water to Phuket, Phang Nga and Krabi

3. Having Surat Thani supply untreated water to Phang Nga and Krabi, but then have a station in Phang Nga supply treated water to Phuket. 

“The majority of people we canvassed supported option two, so we are going with that,” Mr Chamnian said.

Some Surat Thani residents expressed dissatisfaction with the project.

“At one of our public hearings, a resident said that only Phuket people would benefit, and asked what was in it for Surat Thani,” Mr Chamnian told the Phuket Gazette.

“He had a point, so we offered to use money from our budget to sponsor scholarships for local students. They liked the idea.”

Once the project gets EIA approval and the budget is determined, it will be submitted to the National Council for Peace and Order (NCPO) for approval, Mr Chamnian said.
