Notes : “Investment Cost More Effectively Than Recovery Cost” Its caused recovery assets must re-starting again and Company must begin from down level. Why Did People More Thought To Recovery Cost Than Investment Cost? Hal ini dikarenakan mindset kebanyakan orang lebih menganggap bahwa investasi merupakan hal yang imajiner (bayangan/ andai-andai), dan recovery merupakan hal yang biasa dilakukan dan lebih nyata. So, Hal ini merupakan pemahaman yang kurang tepat, karena dari segi Biaya jelas recovery akan lebih besar defisitnya dibandingkan investment. Oleh karena itu, solusinya adalah dengan pendekatan persuasive dan proses Cultural Change yang berkesinambungan akan dapat membangun budaya Preventive Actions secara perlahan.

RISK : one goal of the risk analysis is to communicate the results in common format that a variety of people can understand. RISK MATRIX or PLOT is helpful in accomplishing this goal. 1.

ISO-Risk Line When more Quantitative consequence and probability detect are being used and where showing numeric risk values is more meaningful to stakeholders. A risk plot (or graph) is used J. CONSEPT OF RISK BASED MAINTENANCE 1. INSPECTION PLAN TRADITIONAL INSPECTION PLANNING RISK BASED APPROACH 1. Inspections were Time Based 1. Inspection performed on Basis of Risk Ex : Pemampatan waktu docking kapal, tidak harus mengikuti rule docking selang 5 tahun melainkan cukup merujuk pada kondisi Kekritisan. Hal ini akan memperkecil biaya. 2. Inspections focused primarily on visual examination. 2. Utilize the most appropriate Inspections technique for the detection of pertinent damage or deterioration. Ex : Pressure Vessel bergantung pada jenis material plat dan ketebalannya. Kemudian disurvey untuk seluruh bagian dalam seluruh parameter, hal ini akan meningkatkan biaya. 3. Hydro-testing was specified in some instances. 3. Consider the likelihood of failure based of the remaining life of the item. 4. Focussed on Vessels 4. Consider TOTAL PLANT; Truthly must choose the High Risk. 2. BIG PICTURE
