Reinstating Vital Power Infrastructure in the Philippines Under Challenging Conditions

雅各布的整改工作在地震后恢复Mahanagdong B发电厂的努力提供了强有力的安全和可持续性的成果,赢得了两个着名的奖项。

当地震6.5级scale struck the island of Leyte in the Eastern Visayas region of the Philippines in mid-2017, it caused multiple fatalities, injuries and significant damage to critical local infrastructure. The Mahanagdong B 60 MW geothermal power plant sustained severe damage, and power supply to the whole of the Eastern Visayas region and nearby Bohol island was interrupted.

根据电厂运营商,能源开发公司(EDC)的要求,我们在亚太地区的电力咨询团队立即调动现场,以评估植物损害的程度。我们的初步评估表明,持有植物在山顶的挡土墙的重要部分被山体滑坡损坏,主要的220kV海湾慢慢滑下山上。

一旦初始条件评估完成,我们的工作范围被扩展为包括对修复工程,详细的电气和岩土工程设计,以及补救项目的项目和建设管理服务的选择评估和可行性研究。项目和施工管理阶段混合专家电力工程,采购和建设管理(EPCM)来自我们的珀斯办公室的经验,其中包括当地的项目工程,提供了一个综合的项目交付团队,提供了适用于EDC的合适解决方案。

Remote location hinders access to vital materials and equipment and challenges timeline

该网站的远程表现为团队呈现了许多挑战。位于岛上,位于山顶,只能通过泥土道路访问,刚刚获得卑鄙的壮举。有限的本地选项可用,难以使用,在某些情况下,难以提供的利用和运输材料和设备。例如,没有办法进入现场的混凝土卡车;而是通过当地劳动力手动混合混凝土。

由于将材料运输到现场,该团队修复了现场的并回收材料,在可能的情况下,可以在本地采购材料。这种方法在采购阶段节省了很大的时间,并对修复工作的整体可持续性大大贡献。

具有挑战性的场地条件需要强烈的安全焦点

现场条件呈现了显着的结构和安全风险。在初始网站评估阶段,团队持续大风,余震和进一步地震的风险。在靠近失败的坡度工作,稳定对变电站挡土墙的剩余部分的损坏以及两个大型劳动力在建立新变电站的同时进行补救斜坡的损坏,还有固有的风险。

我们的网站团队实施了强大的安全文化,为EDC及其承包商提供了强大的指导影响。设计团队通过设计原则将安全性完全嵌入到项目中,有助于克服挑战。最终,该项目报告零事件和72,387个安全工作时间,这是鉴于条件的杰出成就。

独特的情况驱动创新解决方案opebet专业版

发电厂的远程位置,损坏的程度以及要进行修复工作的条件意味着该团队必须超越传统的解决方案。opebet专业版该团队提供了多种以标准做法的创新。其中包括将顶部循环生成加压变压器重新定位到发电站点并构建新的230kV变电站;使用钢杆代替传统的着陆龙门,这需要大的基础;在线通电时改装两个损坏的传动塔。

The immediate and demonstrated value of innovations delivered to EDC during the project were over $2.3 million USD.

解决方案核心的可持续性和恢复力

靠在我们的超越可持续发展原则的计划, the team implemented a range of sustainability measures as part of the solution. Reusing and repairing materials that were already on site helped reduce waste and minimize the overall impact of further construction works. Rather than constructing two new transmission towers, the team repaired the damaged ones. This removed the need to clear more land and retained and preserved the existing vegetation. Native vegetation was also protected and maintained through innovative geotechnical designs, enhancing slope protection for the future. Getting the plant back-on line promptly restored green geothermal energy back to the grid, minimizing the use of thermal diesel and coal generation.

Outcome

在该项目的过程中,来自全球11个不同的Jacobs办事处的86人聚集在一起资源项目。尽管有多项挑战,但项目交付是快速追踪的,最终截止到2017年底,符合EDC的侵略性“返回服务”日程表。

The successful project delivery was underpinned by the positive working relationship between Jacobs and EDC, shared sustainability values, and a shared commitment to working towards a zero-carbon future through the delivery of renewable energy projects.

自该项目已完成以来,我们继续使用EDC,为2018年成功完成和委托的顶级周期开关项目提供设计和项目管理服务。

承认和奖项

The team overcame significant challenges and has been recognized for its work and achievements on the project by the Jacobs business, receiving both the Joseph J. Jacobs Reinventing Excellence Award – Category 2 Multiple Services and a Building, Infrastructure & Advanced Facilities (BIAF) Performance Excellence Award for 2019.

As part of the award we’re delighted to have donated $10,000 to the Keitech Foundation. The foundation teaches technical/vocational skills to underprivileged youth in the community of Kananga in Leyte, where EDC’s plant is located, opening the door to new employment opportunities and helping prepare them for a bright future.
