GUMUSUT KAKAP PROJECT
this is one of the giant project that i got involved during my on job training... |
The semi-submersible production system for Gumusut-Kakap field is being constructed by Malaysia Marine and Heavy Engineering’s (MMHE) fabrication yard in Pasir Gudang, Johor, Malaysia. Development drilling commenced in January 2008 and the field will be using 19 subsea wells with oil exported via a pipeline to a new oil and gas terminal, which will be built in Kimanis, Sabah. |

Welding Procedure Specification Example | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
A WPS is a document that describes how welding is to be carried out in production. They are recommended for all welding operations and many application codes and standards make them mandatory What information should they include? Sufficient details to enable any competent person to apply the information and produce a weld of acceptable quality. The amount of detail and level of controls specified on a WPS is dependant on the application and criticality of the joint to be welded. For most applications the information required is generally similar to that recorded on a Procedure Qualification Record (PQR) or Welding Procedure Approval Record (WPAR), except that ranges are usually permitted on thicknesses, diameters, welding current, materials, joint types etc. If a WPS is used in conjunction with approved welding procedures then the ranges stated should be in accordance with the approval ranges permitted by the welding procedure. However careful consideration should be given to the ranges specified to ensure they are achievable, as the ranges given by welding procedure standards do not always represent good welding practice. For example welding positions permitted by the welding procedure standard may not be achievable or practical for certain welding processes or consumables. EN ISO 15609-1 (formally EN 288 Part 2) European Standard For Welding Procedure Specifications EN ISO 15609 Defines the contents of a Welding Procedure Specification in the form of a list of information that should be recorded. For some applications it may be necessary to supplement or reduce the list. For example only in the case of a procedure requiring heat input control would there be a necessity to quote travel speed or run-out length for manual processes. ASME IX American Boiler and Pressure Vessel Code QW 250 Lists the variables for each welding process, all the variables stated should be addressed. The range permitted by the WPS is dictated by the PQR or PQR’s used to qualify it. Typical Items That Should Be Recorded On W.P.S:- Common to all Processes .
A sketch of the joint configuration is required which should include the basic dimensions of the weld preparation. Some indication of the run sequence is also beneficial, particularly if the correct sequence is essential to ensure the properties of the weld are maintained. Production Sequence Whilst this is good practice it is not a requirement of either Non Destructive Testing A WPS is primarily concerned with welding not N D T, this activity should be covered by separate N D T procedures. |

ShiKaRoKiToJi
Friends You have welcomed me into your place and allowed me to make it my home. I will always be grateful for that, which I cannot leave without saying goodbye. This blog has made me into what you think I am. I’ve seen the good in each of you. I’ve seen regular people like you all do extraordinary things. I’ve seen you help each other up after you’ve knocked down. I’ve seen you stand together when times are tough. And I’ve seen the smallest act make the biggest change. If I’ve done anything right, I hope its help you realize one person can make a difference in the lives of others - faith in yourself and you will find hope in each other.
Remember, it’s not the mask that makes the hero. It’s the choices we make and the desire to do what’s right. I’ve seen that desire in all of you. It inspired me to do everything in my ability to protect our relationship. – But I can’t promise that I’ll around forever. One day, we will get to be in our own line, destiny and faith.
But if that day comes, please, keep our friendship remain endless without me to make the world a better place. Be the heroes in friendship I know you are.
