From the NST – Explosion at Labuan PETRONAS plant

February 28, 2010

Taken from the NST, dateline 2010-02-22:

LABUAN: There was a large explosion at the Petronas Methanol Labuan (PML)’s S1001 controlled natural gas Flare Tip that caused operations at the RM511 million methanol plant to cease today. Eighty-two PML contract workers and 46 of its staff were working there when the explosion occurred at 11.37 am but no one was hurt.

Two fire engines from the Labuan Fire and Rescue Service and the PML rescue unit rushed to the scene and controlled the situation within 30 minutes.

Speaking at a news conference, PML production chief, Mohd Kamis Abdul Manap, said a detailed investigation will be conducted to determine the cause of the explosion.

“We will conduct a comprehensive investigation before operations can continue. We will identify if there was weakness in the safety aspect,” said Mohd Kamis

Offhand, I would say failure of the Permit to Work System, opening up the process, air ingress into the vent, improper molecular seal vent, too low design pressure of the vent…

Wow, and I’m making all this up from the news clip above. Synergy would be most pleased in leading the 3rd party safety inspection. You know where we are.

When is an AND Gate an OR Gate? When you DTS

February 27, 2010

Here’s an interesting tidbit I picked up during my FS course in Bangkok.

There are two building blocks used in logic  programming:

And logic associated with these is:

Input Output
0 0 0
0 1 0
1 0 0
1 1 1


Input Output
0 0 0
0 1 1
1 0 1
1 1 1


Now, think in terms of ‘energised’ as Boolean value 1, and ‘non-energised’ as Boolean value 0, then go through the logic of a “de-energise to safe” (DTS) system. Assuming that A and B are sensing elements of a one out of two (1oo2) voting system, then if A or B trip (de-energise), the logic output of an AND gate is 0, i.e. non-energised.

Hence, an AND gate acts as an OR gate in a DTS system. And an OR gate acts like an AND gate.

And Synergy can give you more from where that came from

From the NST – USM Trio turns Waste to ‘Gold’

February 26, 2010

Taken from the New Straits Times, dateline 2010-02-20:

Universiti Sains Malaysia is introducing its award-winning ViscoLigno, a chemically modified biopolymer that functions as a drilling mud gelling and viscosifying agent. Standing out from other more commonly used additives in mud drilling, the ViscoLigno is made of oil palm waste.

Its inventor, USM Chemical Sciences School lecturer Associate Professor Mohamad Nasir Mohamad Ibrahim, said ViscoLigno would prevent the soil from collapsing during the drilling process.

He said the substance would also allow soil residue to rise to the surface, allowing the drill to go deeper into the earth without getting stuck.

ConocoPhillips exec dies in Alaska avalanche

February 25, 2010

Before I start, lets put things into perspective:

From the 2008 annual report, E&P Production:

  • Alaska contribution – 15%, 244kbd
  • Asia Pacific contribution -12%, 91 kbd

From Reuters:

ANCHORAGE, Feb 14 (Reuters) – The president of ConocoPhillips Alaska was killed in an avalanche and a colleague who was part of his snowmobiling party was missing and presumed dead, Alaska State Troopers told Reuters.

The body of Jim Bowles was recovered near Spencer Glacier by rescue workers around lunchtime on Saturday, trooper spokeswoman Megan Peters told Reuters late on Saturday.

“Bowles was pulled from the avalanche debris and CPR was given for about 30 minutes before they stopped the effort,” Peters said.

IEM Shout Out – Welding Requirements for Pressure Vessels

February 23, 2010

This is a shout out for the IEM. My Technical Division will hosting a course on the 2nd and 3rd March, 2010. You’ll get to visit TNB’s Intergrated Learning Solution – ILSAS at Bangi in additiion to getting 13 CPD points.

The course provides basic knowledge and understanding of design requirements to engineers in selecting proper welding technology for pressure vessel manufacturing and structural design. In the course participants will gain basic understanding of the following: –

  1. welding symbols in accordance to AWS A 2.4 and BS EN 22553 (ISO 2553)
  2. behaviour of welded structures under different types of loading
  3. factors affecting fatigue and types of fractures failure
  4. design principles for static pressure vessels and aluminum structures

The Presenter, Ian Partridge, is Principal Project Leader, Equipment Risk Consulting, Structural Integrity Technology Group, TWI. He is a Chartered Engineer (CEng) and Member of the UK Institute of Mechanical Engineers (IMechE), Admitted to the Int. Register of Prof. Eng (IntPE).
