Rigless Remote Intervention: A Case Study of Combo Unit Utilization in Mahakam Offshore East Kalimantan

Mahakam block has been producing for over 40 years and now is in declining phase. Daily drilling and well intervention operations are still actively carried out to sustain and prolong the natural decline curve. Efficiency measures are taken out in each and every aspect of operations to support the diminishing values. One of them is the reduction of offshore platform sizing. Future minimalist platforms have limited top deck space which will further be reduced by the prevalence of: 1. Fixed platform equipment (generators, crane, etc.), and 2. Hazardous area requirement for Zone 0, Zone 1, and Zone 2. The future minimalist platform has a deck space area of approximately 221 m2, not yet taken into account said the reduction factors. The presence of the hazardous area and fixed equipment can reduce the free deck space availability down to 20% from the total deck space. These platforms are not originally designed with well intervention work in mind. However, the past 40 years proves that well intervention should never be left out when extending well’s lifetime is the objective. Well intervention unit, depending on the intervention type, requires top deck space from 26 m2 up to 92 m2 of free space, and an additional 3-4 m2 for lifting, means such as mast unit if the platform does not have a crane. Moreover, in a remote intervention mode, where no supporting barge is present, space requirement above the top deck became crucial as there is no alternative to back load unit to the barge incase the top deck beingover crowded. To support the continuity of remote intervention being more efficient alternative to barge-supported operation, the well intervention team initiates the feasibility study using combo unit as a replacement for conventional slickline and electric line unit. There are three types of combo unit presented in this paper, 1. Split Combo Unit, 2. Combined Drum Combo Unit, and 3. Digital Slickline Combo Unit. These types of unit can reduce the deck space requirement by 30%, reducing number of personnel needed from eight (8) to five (5) personnel in a single shift, improving operation timing efficiency, and improves the contract administration aspect. Despite the seemingly positive results, there are still issues to be resolved, both technical and non-technical, for combo unit to be an all-rounder solution for wireline work. This paper shall provide an early level observation and analysis for the feasibility of combo unit as remote well intervention unit, starting from the methodology to the corresponding results and lesson learnt.

SOCIAL DISTANCING : POTENSI SPLIT LEVEL PADA RUANG ANJUANG DAN GELIGEI SEBAGAI RUANG SEHAT

Design and Analysis of Motor Control System for Wireless Automation

Space availability is one of the major parameter to be considered for structuring a control system. The control system installation occupies space for motors, control circuits, wiring connection and driver units. The motive of this work is to minimize the space requirement for a motor control system by making a wireless communication between the motor driver unit and control unit. The design saves the space requirement for control circuit wiring and control circuit unit. The design is helpful in minimizing the overall space requirement of the motor control system. As the control unit is made with wireless communication, the control unit can be moved anywhere near to the system. This improves the accessibility of the system at fault rectification time and precise operation time. The result indicates the reliability and efficiency of the proposed system with various parametric evaluations.

A novel optimization approach for segmented rabbit chase oriented U-type assembly line design: an application from lighting industry

Purpose Rabbit chase (RC) is used as one of the most effective techniques in manufacturing systems, as such systems have high level of adaptability and increased productivity in addition to providing uniform workload balancing and skill improving environment. In assembly systems, RC inspires the development of walking worker assembly line (WWAL). On the other hand, U-type assembly lines (UALs) may provide higher worker utilization, lower space requirement and more convenient internal logistics when compared to straight assembly lines. In this context, this study aims to improve assembly line performance by generating RC cycles on WWAL with respect to task assignment characteristics of UAL within reasonable walking distance and space requirement. Therefore, a novel line configuration, namely, segmented rabbit chase-oriented U-type assembly line (SRCUAL), emerges. Design/methodology/approach The mathematical programming approach treats SRCUAL balancing problem in a hierarchical manner to decrease computational burden. Firstly, segments are generated via the first linear programming model in the solution approach for balancing SRCUALs to minimize total number of workers. Then, stations are determined within each segment for forward and backward sections separately using two different pre-emptive goal programming models. Moreover, three heuristics are developed to provide solution quality with computational efficiency. Findings The proposed mathematical programming approach is applied to the light-emitting diode (LED) luminaire assembly section of a manufacturing company. The adaptation of SRCUAL decreased the number of workers by 15.4% and the space requirement by 17.7% for LED luminaire assembly system when compared to UAL. Moreover, satisfactory results for the proposed heuristics were obtained in terms of deviation from lower bound, especially for SRCUAL heuristics I and II. Moreover, the results indicate that the integration of RC not only decreased the number of workers in 40.28% (29 instances) of test problems in U-lines, but also yielded less number of buffer points (48.48%) with lower workload deviation (75%) among workers in terms of coefficient of variation. Practical implications This study provides convenience for capacity management (assessing capacity and adjusting capacity by changing the number of workers) for industrial SRCUAL applications. Meanwhile, SRCUAL applications give the opportunity to increase the capacity for a product or transfer the saved capacity to the assembly of other products. As it is possible to provide one-piece flow with equal workloads via walking workers, SRCUAL has the potential for quick realization of defects and better lead time performance. Originality/value To the best of the authors’ knowledge, forward–backward task assignments in U-type lines have not been adapted to WWALs. Moreover, as workers travel overall the line in WWALs, walking time increases drastically. Addressing this research gap and limitation, the main innovative aspect of this study can be considered as the proposal of a new line design (i.e. SRCUAL) which is sourced from the hybridization of UALs and WWAL as well as the segmentation of the line with RC cycles. The superiority of SRCUAL over WWAL and UAL was also discussed. Moreover, operating systematic for SRCUAL was devised. As for methodical aspect, this study is the first attempt to solve the balancing problem for SRCUAL design.

Policy and Attribute Based Deduplication System

Cloud storage is a platform where we can store and access the data through internet. Many Social and business applications are backing up their data in cloud. So, the requirement of cloud storage increases day by day. But most of the files present in the cloud storage are redundant. Removing redundant files in cloud is one way to manage the storage space requirement. For that purpose, we apply File-level data deduplication technique. In this paper, a method for deduplication is proposed which is named as policy and attribute based dedupe system. This system includes access control over files to enhance the security. It also reduces the storage space and increase the security of user data.
