WTS及NLI共同開(kāi)發(fā)海洋應(yīng)用LNG燃料罐
威爾森技術(shù)解決方案（WTS）和近海石油和天然氣工程專(zhuān)家NLI解決方案（NLI），無(wú)論是挪威的公司，已獲得原則性批準(zhǔn)（AIP）從階級(jí)社會(huì)挪威挪威船級(jí)社（DNV）對(duì)他們共同開(kāi)發(fā)的LNG燃料罐的設(shè)計(jì)。
自2009年以來(lái)，兩家公司曾開(kāi)發(fā)的LNG燃料罐設(shè)計(jì)響應(yīng)從船東使用LNG作為船用燃料越來(lái)越大的興趣。該坦克設(shè)計(jì)IMO-B標(biāo)準(zhǔn)，是一個(gè)棱形，大氣和自收自支的國(guó)家的最先進(jìn)的低溫絕熱LNG鋼罐。零件的坦克系統(tǒng)正在申請(qǐng)專(zhuān)利。
Liquiline的，DNV和Marintek的的LNG油箱開(kāi)發(fā)項(xiàng)目的第一階段共同出資由挪威研究理事會(huì)的的MAROFF程序，威爾森海事顧問(wèn)，參與合作伙伴的發(fā)展。
NLI LNG儲(chǔ)罐設(shè)計(jì)的應(yīng)用程序，包括船上LNG燃油艙，坦克碉堡對(duì)液化天然氣的船只，小型液化天然氣運(yùn)輸船和小中型坦克在陸地上。這首由挪威船級(jí)社（DNV）的AIP是有效的，系統(tǒng)將被用作船用LNG燃料罐。
NLI TS-X坦克系統(tǒng)是基于以下原則：
- 棱光不銹鋼罐
- 大氣壓力，0,7的酒吧或以上，等待不同的規(guī)定;
- 高新技術(shù)隔離具有損耗低（幾乎沒(méi)有汽化）
- 專(zhuān)利的固定裝置
- 綜合排水系統(tǒng)/泄漏處理
現(xiàn)在，這兩個(gè)合作伙伴計(jì)劃，以進(jìn)一步發(fā)展坦克的概念，并在未來(lái)促進(jìn)海洋產(chǎn)業(yè)的坦克設(shè)計(jì)和小規(guī)模LNG分銷(xiāo)部門(mén)。
轉(zhuǎn)向使用LNG船舶推進(jìn)據(jù)說(shuō)是從煤到石油的轉(zhuǎn)變，但額外的環(huán)境效益，降低二氧化碳排放量顯著。天然氣價(jià)格預(yù)計(jì)將保持競(jìng)爭(zhēng)力隨著時(shí)間的推移，與柴油和餾分油產(chǎn)品相比也將有一個(gè)顯著的經(jīng)濟(jì)利益，為船東。
Wilhelmsen Technical Solutions (WTS) and offshore oil and gas engineering specialist NLI Solutions (NLI), both Norwegian companies, have received Approval in Principal (AiP) from the Norwegian class society Det Norske Veritas (DNV) on their jointly-developed LNG fuel tank design.
The two companies have worked on the development of a LNG fuel tank design since 2009 in response to growing interest from shipowners to the use of LNG as a marine fuel. The tank is designed to IMO-B standards and is a prismatic, atmospheric and self-supporting LNG steel tank with state of the art cryogenic insulation. Parts of the tank system are patent pending.
The first stage of the LNG Fuel Tank development project was co-financed by the Norwegian Research Council’s MAROFF program, and Wilhelmsen Marine Consultants, Liquiline, DNV and Marintek participated as partners in the development.
The NLI LNG tank is designed for applications including ship board LNG bunker tanks, tanks for LNG bunker vessels, small LNG carriers and small to medium sized tanks on land. This first AiP from DNV is valid for the system to be used as marine LNG fuel tanks.
The NLI TS-X tank system is based on the following principles:
- Prismatic tanks in stainless steel
- Atmospheric pressure, 0,7 bar or more, pending different regulations
- High-tech isolation with low loss (practically no vaporization)
- Patented fixing device
- Integrated drain system/leak handling
The two partners are now planning to further develop the tank concept and in the future promote the tank design to the marine industry and the small scale LNG distribution sector.
The shift towards the use of LNG for marine propulsion is said to be as significant as the shift from coal to oil but with the additional environmental benefit of lower CO2 emissions. There will also be a significant financial benefit for ship owners as gas prices are expected to remain competitive over time compared with to diesel and distillate products.
