Vibration Analisis
|
|
|

Secara umum, getaran akibat unbalance memiliki ciri antara lain: didominasi oleh getaran dengan frekuensi 1XRPM (sama dengan frekuensi putar poros) dan arahnya radial (horisontal dan vertikal). Getaran akibat misalignment memiliki ciri antara lain: getaran dengan frekuensi 1XRPM dan/atau disertai dengan 2XRPM yang relatif besar, dan getaran dalam arah aksial relatif tinggi. Namun, pengalaman lapangan dan beberapa riset menunjukkan bahwa ciri getaran akibat misalignment juga dipengaruhi oleh jenis kopling.

Saya mohon bantuan sekiranya ada kawan kawan yang bisa menjelaskan di forum ini tentang ekspansi gas alam: Study Case: Kondisi Process : Pressure (14.7 psig); Temperatur (83degF); Flow rate (25MMSCFD); Mol Weight(18.73); Spec Gravity (relative) to air (0.6467); Cp/Cv = 1.284. Jika misalkan Gas tersebut saya choke, menjadi 1 psig, apakah flowrate standardnya (MMSCFD)akan menjadi bertambah?

Tender Pengadaan Barang
|
|
|
|
Pada saat Tender diumumkan kualifikasi ditetapkan "Menengah", namun pada saat open bid ternyata OEnya masuk golongan "Kecil" (dibawah 500jt) dan pada tender ini "Prebid Meeting" ditiadakan, apakah menurut penafsiran PTK-007 hal ini dibenarkan? Sebab menurut kami dg penetapan kualifikasi menengah pd saat diumumkan, bidder dalam memilih merek barang sesuai spek dengan estimasi harga pasti akan merujuk ke gol menengah (diatas 1 milyar). Penentuan kualifikasi peserta tender ditentukan oleh Panitia Pengadaan/Bid Com dengan mempertimbangkan beberapa faktor yaitu: jumlah kekayaan bersih (modal kerja), atau omset penjualan perusahaan tersebut dalam satu tahun sebelumnya.

| Taqa to enter Morocco reneweable tenders |
|
The Abu Dhabi National Energy Co (Taqa) has established a division to invest in renewables, and will take part in Moroccos upcoming tenders for wind and solar. The company, which already has a power division in Morocco, is part of a consortium that will bid for a 150MW wind farm in the country within the next few weeks. It will also bid for a 165MW concentrating solar power project, and will consider bidding for one of the five wind farms totalling 850MW for which the government invited tenders last month. The new unit has also begun a feasibility study into an energy-from-waste project in Abu Dhabi, to reduce the emirates burgeoning landfill problem and help meet its growing electricity needs.

| Iran criticises Opec members offering to replace its oil |
|
Iranian oil minister, Rostam Qasemi has criticised some Arab countries for suggesting they could replace Iranian oil in case of disruptions in crude supplies, Reuters has reported. "Some Opec countries should adopt reasonable policies," Qasemi said in a letter to Opec President Abdul-Kareem Luaibi. "The interests of regional countries depend on joint cooperation," Qasemi added. Saudi Arabia, the world's top oil exporter, said last month it could pump more oil at a moment's notice after Iran warned Gulf oil producers not to compensate for any disruption to Iranian output.

| Iran says oil ban would not disrupt nuclear work |
|
Rostam Qassemi, Iran's oil minister has said the Islamic Republic would not retreat from its nuclear programme even if its crude oil exports grind to a halt, and called on the European Union to review its decision last week to ban Iranian oil imports from July 1, Reuters has reported. "We will not abandon our just nuclear course, even if we cannot sell one drop of oil," Qasemi told reporters. Iran would cut oil exports to some nations in Europe in retaliation for the 27-state EU's decision to stop importing Iranian crude, he added.

| Saudi nominates Opec governor for top post |
|
Saudi Arabia has nominated its Opec governor, Majid Al-Moneef for the groups next secretary general, in a move that may reignite a quarrel over influence in Opec between Gulf Arab nations and Iran, Reuters has reported, citing a Gulf Opec delegate familiar with the matter. "There is a lot of support for Moneef. He's well respected and an experienced economist," the delegate said. The current secretary general, Abdullah al-Badri of Libya, completes his second and final three-year term at the end of 2012. Opec will seek to select a replacement, to start in 2013, at its next meeting in June.
