Design and Analysis a Harvesting Mechanism of Swiftlets Nest

Industry swiftlets nest is not a new industry in Malaysia. It gets very high demand from China. Harvesting swiftlets nest is one of the processes to produce any products that made from swiftlets nest. Currently, they are using manual harvesting equipment to harvest swiftlets nest without using any auxiliary equipment. It is the first step in process flow and very important role before cleaning process. The objectives of this project are to design mechanism harvesting equipment to harvest swiftlets nest and to decrease the time of harvesting swiftlets nest process in a swiftlets house in a day. The methodology of research is including collect data, brainstorming, design concept generation, concept selection and simulation analysis. The design of harvesting equipment is using CAD software and analyze using FEA analysis. At the end of this project, this research will give understanding about design using CAD software and analysis that improved the harvesting equipment.

Success Story of First Malaysia Flare Tips Decommissioning in Sarawak Offshore Field Platform

The project was for part production enhancement project which to cater for brownfield & greenfield project. To cater to the production (oil) increment for the brownfield project, the existing flare tips and separation system need to be upgraded with higher capacity. The inclusive project was upgrading existing. Part of the scope was decommissioning the existing flare tip and associated system, e.g., ignition panel and ignition pipe. The project will decommission the current flare tips and replaced it with new higher capacity flare tips with Low Pressure (LP) & High Pressure (HP) connection. The existing flare panel was a single-type ignition system. The existing flare tip had LP & HP tip with 8″ inch size; the weight for both tip was estimated at 300 kg. The concept selection was discussed on the suitable method to lifting down the decommissioning flare tip at the offshore platform. There were 2 suitable techniques selected at the initial of the concept selection. One was lifting down the decommissioning flare tip directly from flare boom to vessel. Another method was manual rigging of the flare tips from the flare boom to the lower deck. After several discussions and workshops, it was decided to proceed with manual rigging of the decommissioning flare tip to the safe deck area. The removal of the decommissioning flare tip was performed during turnaround. The total days for the overall activity of the decommissioning & installation of the new flare tip was 3 days, 2 days ahead from planned duration 5 days.

Collaborative Engineering and Design Leads to Optimized MPD Land Rig Concept

This paper presents a land rig concept optimized for managed pressure drilling (MPD) service deployment, achieved through close partnership between an MPD technology provider and a drilling contractor. An initial scoping phase identified high-level requirements based on the Operator's planned drilling plans. After the initial concept selection engineering teams continued to optimize MPD rig integration. The engineering teams collaborated closely on optimal placement and configuration for maximum operational efficiency. The system was designed to facilitate fast rig moves and walking within each pad with minimum disruption to other processes. Safety and handling issues were identified in the detailed design stage and allowed optimizing field deployment and operability. The equipment was paired with an MPD control system that was fully integrated in the rigs’ drilling automation platform, enabling consistent, reliable, and repeatable performance. This paper will outline the concept selection process, the design and deployment phase, and further optimization that was implemented after initial learnings.

Connecting Design Actions, Reasoning, and Outcomes in Concept-Selection

Final concepts are often not the most creative or innovative design within the solution space. The purpose of this research is to gain insight into the decisions made in concept selection. In particular, we studied how designers link multiple decision-making elements together, including: actions (what people do), reasoning (why they do it), and design outcomes (an objective measure of engineering performance). Fifty-seven participants were tasked with solving a design challenge relating to a robotic gripper by selecting a design within a predefined design space. Each design had a corresponding measure (termed “success rate”) which enabled each designer’s performance to be quantified and compared against other designers. The task was hosted on an interactive interface in which design actions were collected. A post-task survey probed for the reasoning behind design actions. Characterization of decision-making behavior and reasoning was rooted in prior design literature. Design actions were quantified concerning the degree of design space explored and the decision-making strategies employed. Key results include design strategies such as manipulation techniques, the impact of maximum observed success rates, and a willingness to submit an alternative solution which influenced design outcomes. Although designer preferences validated the design strategies identified, there was no correlation between the decision factors considered and improved outcomes. The methods and findings from this work assessed the underlying dynamics when engineers selected less innovative or creative solutions and recommended decision-making strategies that should be considered to improve design outcomes.

The World Deepest Electrically Heat-Traced Flowline

Electrical heat tracing technologies for flowline applications have been in development phase for some time. Yet in recent years, the efforts to deploy this technology on real life applications have intensified, leading to several projects in the industry simultaneously adopting this solution. As often seen with technology development, implementing the serial number 1 of a technology requires one project with favorable conditions and parameters, but also the stakeholders willingness to face the challenge associated to being first, and having to cross the final gap between the qualification program and this real life application. This paper presents how a specific project met all the conditions to be the first to select and implement a deepwater EHTF® (Electrically Heat-Traced Flowline) solution. This paper presents the Project from the concept selection phase, to the execution and offshore installation of the final product. This provides an overview of why this technology was selected, and how the Project was executed, with a focus on the main challenges encountered and the associated solutions. The concept selection phase for this two-well development consisted of comparing subsea tie-in architectures to tieback architectures using one or several new risers. The EHTF® emerged as the highest value solution, offering the best compromise between technical, economical, risk and schedule criterion, as it enabled single line tieback, while significantly reducing the operational risks associated to such architecture. A FEED was launched to further define and accurately estimate the concept, in order to reach FID. Close collaboration between the Operator and the Contractor at every step of the process allowed the solution to be selected and developed in a fast track manner while enabling the Contractor to provide an optimized, tailor-made solution. The project execution involved many work sites, including the Vigra spoolbase in Norway for EHTF® fabrication, as well as the Seven Vega, which was a brand-new addition to the pipelay vessels fleet at the time of the Project. Many challenges arose during the project execution, as the qualification program was being completed, but adequate solutions were developed, allowing the Project to continue its course. Obviously, there were many lessons learned along the way, which will feed into further product development plans, in order to improve its technical performance and competitivity. Heat tracing solutions offer great opportunities for single line long tieback development which often come with elevated operating risk profile due to complex wax and hydrate management. Enhanced thermal performance of resistive heating systems makes it possible to operate with low power consumption, which is a key in today's world of energetic efficiency.
