Query – Simple Modelling of FPSO Vessel Rocking?

December 7, 2008

I’m curious whether anyone bothers to model the roll of a FPSO inside a process simulation package.

  1. I know that you can build vessels where you insert baffles to minimise the sloshing of liquids (does sloshing approximate to a simple harmonic motion system?), and Hysys allows for re-entrainment in the outlet (is there a simple formula which can approximate this?).
  2. Does a properly built vessel dampen the sloshing effect such that it’s not worth even thinking about vessel roll? What’s the largest vessel roll anyway?
  3. You can simulate the sloshing using computational fluid dynamics, but is that overkill?

Your answers and pointers would be interesting

IEM Jurutera Nov 2008 – Interesting Articles

December 4, 2008

The bulletin of the IEM for the month of Nov, 2008 was themed Chemicals and Petrochemicals.

Articles which might be of interest to the oil and gas industry are:

  • Issues on Natural Gas Distribution in Malaysia
  • IEM Kerteh Chapter Activities April-July 2008.

Okay, it’s only 2 articles, but the other articles are on petrochem topics. And the front cover shows two semisubs (okay, I’ve been on a fetish for the past couple of weeks).

Petrol Prices Drop in Malaysia

December 3, 2008

From the New Straits Times Online (change of loyalty here)

JOHOR BARU: Pump petrol prices will be further lowered before Hari Raya Aidiladha next week, Domestic Trade and Consumer Affairs Minister Datuk Shahrir Abdul Samad said yesterday.
He, however, declined to reveal the exact quantum of the price reduction, only saying that it would not be greater than the previous reduction of 15 sen per litre.

Shahrir was speaking at the closing of a business development seminar for traders and small enterprises at a hotel here.

The minister said there was a possibility that the price of diesel would be higher than that of petrol after the price revision.

“Now, we are facing an extraordinary situation, where diesel may be priced higher than petrol at the pump, and that’s the reason for the continued 43 sen subsidy for diesel as the price of diesel has become almost at par with petrol,” he said.

I’m curious when exactly gas prices will start following market prices.

New HAZOP Tool

November 27, 2008

I facilitated a HAZOP for Uzma on Sunday, 23rd November, 2008, in Kerteh Terengganu (yes, I was doing it under the Poyry ticket).

Anyhow, I found that the following tool is extremely useful in:

  • pointing out items on the projection screen.
  • Demonstrating heights and lengths.
  • Just feels cool.

I suggest using one about 4 1/2″ long, an inch thick.

I wonder when we’ll make t-shirts like these, ‘OLGA power user inside,’ or ‘dyn sim maestro inside’.

NOEX – Celebration of 5 years SK10 Production

November 25, 2008

On Nov 20 (Thursday), Nippon Oil celebrated 5 years of SK10 Production (that’s Helang field to you and me) at the Oriental Mandarin. It was a colourful night, where I represented Poyry. It was nice of NOEX to mention that they donated RM333,000 to the Miri General Hospital. Is it no coincidence that the PSC NOEX had recently been awarded is called SK333, and it covers part of Miri town?
