The development area covers Block M9 and small portion of Block M11， owned by Myanmar Oil & Gas Enterprise (MOGE). The field lies approximately 300 km south of Yangon and 290 km west of Tavoy on the Myanmar coast and the average water depth is approximately 140-150 meters.Figure 1.1: Zawtika Field LocationZawtika field development is planned in three phases 1A (existing facilities)， 1B and 1C as per Figure 1.2 Zawtika Field Layout. Phase 1A development consisting of Zawtika Processing integrated with living quarter platform (ZPQ)， WP1， WP2， and WP3 is currently being developed. Commercial production is expected to commence in the first quarter of 2014. Phase 1B and 1C (remote wellhead platforms) will be developed in order to sustain production plateau through the field life.Figure 1.2:Zawtika Field Layout1.2 ObjectivesThe intent of the HAZOP review is to systematically review the design and operations of the WP4/5/7 and WP4 facilities and Brown Field modifications of existing platforms ZPQ， WP2， and WP3 to identify any safety and operability problems associated with the processes.The risk management objectives of the HAZOP Review are to: Identify safety related hazards and operability concerns related to the process; Determine the consequences for the identified hazards and operability concerns; Identify engineering safeguards and future procedural controls already incorporated into the design that will reduce the likelihood， or associated consequence， of the identified problems; Evaluate the adequacy of existing engineering safeguards and future procedural controls in place for the facilities; and Recommend additional engineering safeguards and/ or future procedural controls， where necessary.Note that risk ranking will not be conducted for this HAZOP Study.1.3 Scope of studyThe scope of the HAZOP study includes review of topsides design associated with the following facilities: Four new remote wellhead platforms (WHP) named WP 4， 5， 6， and 7 with pre-installed risers. WP4， WP5， and WP7 are 20-well slot type platform. WP6 is 12-well slot type platform. Four associated pipelines (IP4， IP5， IP6， and IP7) with their dog leg tie-in. The telecommunication and control systems integration WORK into existing facilities in ZAWTIKA field. Brown Field modifications of existing platforms ZPQ， WP2， and WP3.The HAZOP review will mainly address normal operating conditions.SIMOPS activities are not included in the scope of work.Vendor packages are excluded from the scope of the study.HAZOP will be conducted based on WP6 and WP4/5/7 Piping and Instrument Diagrams (P&IDs)， Issued for Approval Revision， provided by COOEC.Future facilities such as the Booster Compressors on WPX are excluded from the scope of this HAZOP review as the information available for these facilities are still at the preliminary stage.2 执行计划、参与人员及流程介绍2.1 时间和地点HAZID计划执行2天，将于2014年X月XX日开始，2014年X月XX日完成。审查时间是每日9：00至17：30，其中包括1小时的午休时间。表2.1 HAZID会议执行计划表（第一天）Time Activity9.00 am HAZID组成员自我介绍9.15 am 推选HAZID组长9.30 am 工程方案分析10.30 am 休息10.45 am 制定HAZID引导词12.00 am 午餐2.00 pm 逐项细化风险识别与记录（1）3.45 pm 休息4.00 pm 逐项细化风险识别与记录（2）5.30 pm 结束当天会议Table 2.2 HAZID会议执行计划表（第二天）Time Activity9.00 am 昨日成果回顾9.15 am 逐项细化风险识别与记录（3）10.30 am 休息10.45 am 逐项细化风险识别与记录（3）12.00 am 午餐2.00 pm 主要风险HAZID汇总3.45 pm 休息4.00 pm
