HAZID技术要求与执行要素

1 项目概述

1.1 General

The Zawtika Project is a gas field development project located in the Gulf of Martaban，Myanmar. 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 Location

Zawtika 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.

1.2 Objectives

The 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 ne cessary.

Note that risk ranking will not be conducted for this HAZOP Study.

1.3 Scope of study

The 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.
