4th week internship

Before I proceed for the 4th week of internship, i would like to update the last week task perform by me.

On last friday(23/4/2010), I've been working from 9a.m till 9.30p.m because i'm assisting Mr. Azlan to complete the tender. I've been assign to do the photocopy of the tender and organize the tender based on the partition given. During completing the task, I had noticed the tender is regarding the pigging. All the priced and the specifications is explained in the tender. All the principles and procedures also being briefed in the tender.

On monday(26/4/2010) this week, I had a medical leave due to my illness and unavailability to go to work.

On Tuesday(27/4/2010), there aren't much to do because of my illness. I just read the article regarding trenching operation from the previous tender to understand the principle of the trenching machine. I also had accompanying Pn. Noraini(logistic) to the commissioner of oath at kelana jaya to get the chop and signature for declaration of our barge is able to be used in the next project.





Here is the drawing of the trenching machine of our company. Our trenching machine is using the water to blow the seabed for the trench activity.

On Wednesday(28 April 2010), I feel very diligent. I just finished my research on the trenching activity with supported photos for trenching activity. All the info have been filed to prepare to do the report after finish the internship. Here are the photos;

1)



Here is the baby barge that will be used to place the equipments for trenching activity. We called it baby barge due to its size that it smaller than the standard barge. All the equipments will be welded on this barge.

2)


This photo shows the equipments is being installed on the baby barge. The blue box is the hydraulic pump and winches is installed to each edge of the barge. The silver colour behind the air compressor is the water jetting pump to pump the water into the trencher during trenching.

The baby barge is being installed and ready for the work.


Tomorrow I will proceed the explanation on the trenching work...

to be continued......

3rd week of the internship.

Begin from monday 19 April 2010, I've been assigned to submit the quotation for the trenching project (Sapangar, Sabah) at the Sapura building@mines. This quotation is proposed for the bidding session with other contractors to compete for the tender. The lowest price proposed and very good reputation of the company is the criteria to win this bidding.

In the evening, I've been attending the meeting for purpose of postmortem from the previous project in MIRI, Sarawak. There we discussed the weakness of the previous project to be improvised. We proceed the meeting till 9.30p.m for the coming project that is Sapangar project. We discuss the method to implement in that project before proposed it to our client (Petronas carigali SDN. BHD or PCSB) on the next day.



On the Tuesday (20 April2010), We as OMBAK MARINE GROUP team consist of 7 people including me had been attending the meeting with our client, PCSB at KLCC meeting room. There we have a lot of discussion regarding the coming project. En. Anwar from PCSB is the person in charge for the project. He will monitor our working procedures and the project will done within the schedule period. The issue during the meeting is either use concrete collar method or grouting method for the pipeline installation before we proceed to do trenching work.

The meeting end during the lunch hour. Then, we had a lunch and met with the supplier for the grouting method at mutiara Damansara to have a deep knowledge for that method. After got a lot of info, we decide to proceed with the concrete collar method which is practicable compared to grouting method.

On 21 April 2010, I've been assign to complete the organization chart for the Sapangar project. I also compile their CV before submit it to the PCSB for the prove we could manage this project.

ISO project for 2nd week intership

Suddenly, today I got ISO project to be done due on june. This morning we had a meeting regarding this project. The task should be start now... This project will replace all my Internship period in OMBAK, perhaps my experience in OMBAK is doing the ISO project but not being exposed in oil and gas industry... For me, it is okay but I will steal my time to expose my self in oil and gas because I don't wanna loose my opportunity to get along with the experienced engineer in this company. I want to know every scope of the company projects until I could explain to the others by my self regarding the projects done in this company because during presentation soon, we need to explain to the lecturer about our role in the company and understanding of the company vision and mission. Today, I've get through the requirements for the task and tomorrow I will ask my Manager Representative(MR) to start the task given..

si semalam....

kali ni dalam versi bahasa melayu pula. Yes, mmg semalam kitorg dpt 1 task sal research in upstream line. hahaha musti korg ternganga ble dngr term tu kn. Sebenarye, upstream ni melibat kn exploration and production lam oil and gas ni. apekah exploration dan apekah production kn? ok2, exploration tu mcm satu company akn search sesuatu tempat tuk buat projek minyak nih. production pulak, set up equipment n mcm2 lagi kt site yg dah berjaya di temui tuh la...cmtu la basic research kitorg.


En. Zamri yg bg tugas ni. yela, dia general manager kt sni. so dia bole bg pape tugasan kt kitorg. memang la x sibuk ble dpt 1 task je, da bese ngn projek belambak kt uniten tuh. tp disebabkn xsibuk ni la jd mls...haduiiii, perangai yg xley di ubah. ok la, xperlu menulis panjg sbb kj pon xsiap nih. due date selasa dpn, kami kne struggle sbb bnd ni leceh...ok la, tu je...bye2....

Hot tapping and Pigging

Yesterday, I had learned about the HOT TAPPING and PIPELINE INSPECTION GAUGE (PIG). This method is used in oil and gas industry and it is definitely under piping work. I will explain a little bit for both methods later. For recap, my previous post is about the barge, davit (crane frame), trencher and trenching method (video). Those were a few things that is related to the offshore work. Now, let us get familiar with another method.

The method is

Hot tapping, or pressure tapping. It is the method of making a connection to existing piping or vessels without the interruption of emptying that section of pipe or vessel. Hot tapping is also the first procedure in line stopping, where a hole saw is used to make an opening in the pipe, so a line plugging head can be inserted. You don't need to be confuse because my video here will explain every things about the process.

(hot tapping video)….

Hot tapping can be performed on pipes carrying natural gas, water, sewage, steam, petroleum products, and chemicals, and on any type of pipe.

Second thing is pigging. A pipeline inspection gauge or pig in the pipeline industry is a tool that is sent down a pipeline and propelled by the pressure of the product in the pipeline itself. There are four main uses for pigs:

1. physical separation between different liquids being transported in pipelines;
2. internal cleaning of pipelines;
3. inspection of the condition of pipeline walls (also known as an Inline Inspection (ILI) tool);
4. Capturing and recording geometric information relating to pipelines (e.g. size, position).

Pig is been made with several of material. One kind pig is a soft, bullet shaped polyurethane

foam plug that is forced through pipelines to separate products to reduce mixing.

There are several types of pigs for cleaning. Some have tungsten

studs or abrasive wire mesh on the outside to cut rust, scale, or paraffin deposits off the inside of the pipe. Others are plain plastic covered polyurethane.

Pigs cannot be used in pipelines that have butterfly valves but it can used in the ball valves. Butterfly valves have a plate inside it that can block the movement of the pig.

Inline inspection pigs use various methods for inspecting a pipeline. A sizing pig uses one (or more) notched round metal plates that are used as gauges. The notches allow different parts of the plate to bend when a bore restriction is encountered. More complex systems exist for inspecting various aspects of the pipeline.

Intelligent pigs, also called smart pigs, are used to inspect the pipeline with sensors and record the data for later analysis. These pigs use technologies such as Magnetic flux leakage (MFL) and ultrasonics to inspect the pipeline. Intelligent pigs may also use calipers to measure the inside geometry of the pipeline.

Get familiar with the oil & gas term and project

Yesterday, I put my full effort to understand the term used in the oil and gas sector and also i have learned their procedure and analysis of their project by read through their previous projects. Basically, OMBAK marine practicing the pipe line work at the site. In order to do the work, certain machinery and equipment should be recognized and their procedure and analysis should be done before going to the site work.

As an example, OMBAK got the project at Terengganu Crude Oil Terminal (TCOT) to do the pipeline from ANDR-A to TCOT. The first thing they need to do is prepare the procedure and the analysis. It is also containing the equipment should be brought or rent,person in charge, calculation and the arrangement of the equipment from the older site the the new project site.

For this time, I will introduce to you (readers) the machinery used to do the project on the site practiced by OMBAK.



This is a BARGE (I got from internet). In OMBAK, we used type POE Giant 7 (PG7). We used this barge as our big crane on the sea. All the lifting and lowering activities is done by this huge vessel. On the barge, we can do the welding activity. In order to do the mid-point tie-in activity (welding/merging within two pipeline), the two different pipeline will be lifted by the davit(like a crane on the barge) and it will bring it on the barge to weld it together. Then, it will be lowered down back to the seabed.




This is one of the type of trencher (OMBAK used the other type). It is functioned to trench the seabed in order to lay down the pipeline under the seabed. Below shows some trenching activity.







This is also kind of oil and gas activity. OMBAK just doing the pipeline activity for now and perhaps will expand their business scope later.

There are also many things should be consider when doing the project and also many equipment should be recognize but I will explain those later....

Enjoy reading, byeee!!!

The whole Yesterday

Yesterday was my first day in OMBAK marine. This company is located at Kelana Square, Kelana Jaya. Yesterday morning, I arrive there early to show a better image in front of them. Then, in the waiting area, I saw another uniten students also have an industrial training here. They were Juares Rizal and Firdaus. But actually Firdaus is doing part time there. He had doing intern at OMBAK sometime ago.

After we got to know each other, we have been brought to the entire office to introduced our selves. It just take a few minutes, then we got our own cubical. There were our place to do the job for this entire period of internship.

We have been mentored by Mr. Fahidin. He will be our supervisor for this training. Yesterday, he gave us the task to be done. That will be our first task in OMBAK. The task is about subsea production system (SPS).

That's all for now....bye bye!!
