Plate Heat Exchanger Cleaning

Heat Exchanger

Heat exchanger is the common equipment you can found in the power plant process. The reasons why I put plate heat exchanger cleaning is to share what is needed to be done on the old or defective plate heat exchanger on my machine.

In order to make heat exchanger function properly, all tubes must be cleaned and free from any debris. Heating and cooling process in the heat exchanger also contribute to debris growth and corrosions, besides dirty water in the pipeline.

Normally what we did on the heat exchanger cleaning is including checking, regasketing, dye penetrant testing, and chemical services and repressing of deformed plates.

Incoterms 2010 (NEW RULES)

A part of procurement knowledges applied in my routine job. Just to share with you all.

The global economy has given business broader access than ever before to markets all over the world. Goods are sold in more countries, in larger quantities, and in greater variety. But as the volume and complexity of global sales increase, so do possibilities for misunderstandings and costly disputes when sale contracts are not adequately drafted.


The INCOTERMS rules, the ICC rules on the use of domestic and international trade terms, facilitate the conduct of global trade. Reference to an Incoterms 2010 rule in sale contract clearly defines the parties’ respective obligations and reduces the risk of legal complications.


Since the creations of the Incoterms rules by ICC in 1936, this globally accepted contractual standard has been regularly updated to keep pace with the development of international trade. The Incoterms 2010 rules take account of the continued spread of customs-free zones, the increased use of electronic communications in business transactions, heightened concern about security in the movement of goods and changes in transport practices. Incoterms 2010 updates and consolidates the ‘delivered’ rules, reducing the total number of rules from 13 to 11, and offers a simpler and clearer presentation of all the rules. Incoterms 2010 is also the first version of the Incoterms rules to make all references to buyers and sellers gender-neutral (adapted from Rajat Gupta, ICC Chairman).

The broad expertise of ICC’s Commission on Commercial Law and Practise, whose membership is drawn from all parts of the world and all trade sectors, ensures that the Incoterms 2010 rules respond to business needs everywhere (adapted from Rajat Gupta, ICC Chairman).


Incoterms rules define the responsibilities of buyers and sellers for the delivery of goods under sale contracts. They are the authoritative rules for determining how costs and risks are allocated to the parties. Incoterms rules are regularly incorporated into sale contracts worldwide and have become part of the daily language of trade.

Incoterms 2010 CONTAINS THE ICC rules for use of the 11 Incoterms trading terms. It takes into account the latest developments in commercial practice and updates and consolidates some of the former rules. All sales contracts should make reference to the Incoterms 2010 rules as the latest version of the Incoterms rules.


The International Chamber of Commerce (ICC) had recently revised the Incoterms rules. The new Incoterms 2010 launced on 27th September is effective worldwide as of 1st January 2011.


Incoterms are interntional rules published by the ICC for the interpretation of trade terms eg EXW, FCA, FAS, FOB, CFR, CIF etc. Importers, Exporters, Bankers, Insurers, Freight Forwarders, Customs Brokers and carries need to be aware of the new changes in Incoterms 2010 which have critical implications to their business especially on the following:

• Carriage of goods between seller and buyer
• Export and Import clearance requirements
• Allocation of costs between seller and buyer
• Acquisition of transit/cargo insurance
• Assumption of risks for loss and damages

The changes in the new Incoterms rules are massive, sweeping as well as practical. Four terms under the current Incoterms 2000 were taken out. Two new terms DAT (Delivered At Terminal) and DAP (Delivered At Place) have been added.

Offshore Oil Rigs Mechanical Completion & Commissioning, Including Construction

Rationale for this Workshop

80% of the world's rig-building market is concentrated in Singapore. Consequently, shipyards in Singapore designs and builds 60% of the rowld's jack-up oil rigs.

• Destruction or damages done to offshore oil rigs due to sucessive hurricanes
• Many of the current oil rigs had reached their life expectancy and required replacing
• Recent BP oil spill - many exploration companies rush to replace their old rigs with new ones so as to meet the stricter regulations and rules governing the construction of oil rigs.

However, many of these new-build oil rig projects are delayed due to the commissioning process. Such delays are a threat to the profits of the project and often involve conflicts between the main stakeholders of the project such as:

• The yard/factory/workshop representing the services company/vendor
• The construction team of engineers
• The commissioning team of engineers
• The operations team and the coming crew of the unit or ship

Reason for Attending

• Equips delegates with the knowledge to understand and implement efficiently the mechanical completion, commissioning and conflict resolution activities of oil rig units
• Provide attendees with a more strategic approach to commissioning, along with numerous tools to use throughout the commissioning process
• Through the workshop, each delegate will improve job performance by attaining
• Better alignment of mechanical completion & commissioning process steps with stakeholder’sneeds
• Better commissioning procedures
• Better mechanical completion
• Fewer disputes and claims
• Better project outcomes
• Essential for all involved parties to understand the entire process, keys to success and what is required of their own roles
• All materials and exercises are particularly specific to the oil rig industry in Asia to be more relevant to the needs of the delegates
• Content is developed from both a rig owner’s and shipbuilder’s point of view.
• Round table discussions are also included so that delegates are actively invited to share their view

Hulu Terengganu Hydroelectric Project

Hulu Terengganu Hydroelectric Project is proposed to Terengganu State Government for electric power supply. The hydroelectric project own by Tenaga Nasional Berhad.

The project is set to commence on 2010 and will be completed 2014. This crucial for TNB where the project need to be completed on time since the demand on the power supply expected to increase in 2013 onwards. One more thing is Bakun Project which expected to supply power to Semenanjung will be not realized due to some problem. Maybe the problem rise on the underground sea cabel issue.

More details: TNB to build another hydroelectric Plant in Terengganu.

Depth Micrometer

Micrometer

What is micrometer? A simple meaning can be thickness measurement, an instrument that measures small distances, angles or objects. A micrometer sometimes known as a micrometer screw gauge, is a device used widely in mechanical engineering and machining as well as most mechanical trades for precision measurement, along with other metrological instruments such as dial calipers and vernier calipers.

Depth micrometer

The depth micrometer is used to measure the precise depth of holes, grooves and recesses by using interchangeable rods to accommodate different depth measurements. When using a micrometer, you must make sure the base of the micrometer has a flat, smooth surface to rest on and that it is held firmly in place to endure an accurate measurement.
