Zusammenfassung. Vorgestellt wird das IBES (Inventar berufsbezogener Einstellungen und Selbsteinschätzungen), das erste publizierte deutschsprachige Verfahren der Gattung “Integrity Test”. Ziel des Instrumentes ist die Vorhersage kontraproduktiven Verhaltens in Unternehmen (z. B. Absentismus, Diebstahl, Aggression). Die Konstruktion erfolgte in enger Anlehnung an Inhalte prominenter amerikanischer Integrity Tests. Das IBES besteht aus einem einstellungsorientierten Teil mit 60 Items, die den vier Skalen “Vertrauen”, “Geringe Verbreitung unerwünschten Verhaltens”, “Nicht-Rationalisierung” und “Verhaltensabsichten” zugeordnet sind sowie einem eigenschaftsorientierten Teil mit 55 Items, unterteilt in die fünf Skalen “Gelassenheit/Selbstwertgefühl”, “Zuverlässigkeit/Voraussicht”, “Vorsicht”, “Zurückhaltung” und “Konfliktmeidung”. Die Anwendbarkeit des Verfahrens in der Praxis wird insbesondere vor dem Hintergrund der Datenbasis und des Itemmaterials kritisch diskutiert.

Abstract Four high-pressure-high temperature (HPHT) and sour gas wells are currently operating at Madura offshore as the only productive assets for Husky-CNOOC Madura Limited (HCML). Each well performance is very crucial to fulfill the demand of the gas customers in East Java, Indonesia. Since starting production in 2017, the wells experienced two main well integrity challenges, high annulus pressure and wellhead growth. Both challenges are very dependent to the well flow rate and the flow duration. A continuous operation monitoring is highly required in order to keep the wells operating safely. To overcome the challenges, HCML established a Well Integrity Management System (WIMS) document that approached several international standards as its basis. As company grows, development plan challenged the WIMS to perform faster and more efficient as compared to the existing manual system. From there, the journey of WIMS digitalization began. The journey started with the alignment of the existing WIMS document to the ISO-16530-1 at Operational Phase with more stringent boundary to operate the wells safely. The alignment covers, but not limited to the organizational structure, well barriers and criteria, monitoring and surveillance, annulus pressure management, and maintenance. The document also covered risk assessment and management of well integrity failure, which was the backbone of the WIMS digitalization. The current digital solutions allow production data to be accessed and retrieved directly from the system for analysis purposes. It compares the recorded data with pre-determined rules and parameters set in the system. It triggers a notification to the responsible personnel to perform the required action should any anomaly occurs. It also can send a reminder to users to schedule and complete a well Integrity test to ensure that a well is always in compliance with the WIMS. All test reports and documentation are stored in the system as preparation for any future audit. A key requirement of the expert software system was access to future developments that can offer enhanced functionality of the well integrity platform through additional near time capabilities such as predictive erosion and corrosion for downhole flow wetted components. This is being developed to enhance workover scheduling for existing wells and material selection for new wells and is planned to update automatically critical well integrity criteria such as tubing burst, collapse and MAASP.

Fondasi harus dibangun di atas tanah keras agar bangunan tetap stabil dan kokoh. Memastikan kekuatan fondasi adalah upaya dini untuk mencegah sudden collapse pada bangunan di kemudian hari. Penelitian ini dilakukan untuk mengetahui kuat dukung tanah pada ujung tiang fondasi dan mengamati sejauh apa kerusakan beton tiang bor pada bangunan yang baru masih dalam tahap pembangunan fondasi. Data penelitian diperoleh dari hasil pengujian PDA (Pile Driving Analyzer) dan PIT (Pile Integrity Test) pada fondasi bangunan jenis bored pile D80. Pada gedung yang berdekatan, yang dikerjakan dengan sistem yang sama dan menggunakan spun pile D50. Data kuat dukung ultimate hasil manometer alat uji hidraulik 175 ton untuk pile D50. Dari analisis uji PDA, diperoleh nilai kuat dukung ijin rata-rata tiang bor adalah 70,25 ton (51%). Analisis ulang terhadap kombinasi beban menghasilkan tambahan spun pile di 44 titik. Pada beton bored pile yang mengalami kerusakan, dilakukan perbaikan seperti penambahan cor pada lapisan luar (concrete-jacketing) untuk menutupi lapisan tulangan yang terekspos, dan penambahan tulangan terpisah di sisi dalam beton untuk antisipasi bila tulangan luar rusak akibat korosi.The foundation must be placed on hard rock so that the building remains stable and solid. Thus, ensuring the strength of the foundation is an early effort to prevent sudden collapse of the building in the future. This research was conducted to determine the bearing strength of the soil at the ends of the foundation piles and to observe the extent of the damage to the drill pile concrete in the new building which is still in the foundation construction stage. The research data were obtained from the results of PDA (Pile Driving Analyzer) and PIT (Pile Integrity Test) testing on the foundation of the bored pile type D80 building. The adjacent building is being worked on with the same system and using a D50 spun pile. With the ultimate bearing strength data, the results of the hydraulic tool manometer = 175 tons for D50 piles. PDA test analysis obtained the average allowable bearing strength of the drill pile is 70.25 tons (51%). The re-analysis of the load combination resulted in additional spun piles at 44 points. In the damaged bored pile concrete, namely by adding cast to the outer layer (concrete-jacketing) to cover the exposed reinforcement layer, and adding separate reinforcement on the inside of the concrete to anticipate if the outer reinforcement is damaged due to corrosion.Fondasi harus dibangun di atas tanah keras agar bangunan tetap stabil dan kokoh.
