1 INTRODUCTION

Nexus Deepwater Engineering Inc. (NEXUS) is a Houston Based engineering company

that has the most innovative independent subsea deepwater / shallow-water

engineering and management consultancy, with a team that brings over 30 years of

experience. Our global team capacity and offices are as following:

The Houston office has been operating since 2008 at 908 Town & Country Blvd

Suite 120, Houston Texas.

The Kuala Lumpur office has been operating since 2009 at Menara Citibank, Level

36, 165 Jalan Ampang KL. We have also opened our new engineering office on

Level 9-1 in Wisma UOAII, Jalan Pinang 50450 KL. The office is located near the

Petronas Twin Towers.

The Perth office was opened in the city center located in the AMP Tower close to

Woodside.

The Vietnam office also opened its doors on 1st October, 2012 in Ho Chi Minh

City’s main business district.

In 2008 NEXUS was formed by the joining of Oceanus S.A., NG Solutions and Rabia

Enterprises (Pvt Ltd) to provide a consolidated Subsea engineering (shallow and

deepwater), floating systems and construction management services. We are backed up

by a full suite of unique in-house specialist software, our comprehensive subsea and

topside capabilities include expertise in Project Management, Project Engineering, pre-

FEED, FEED, Bid Evaluation, Project Execution, Vessel Selection, Pre-Commissioning,

Installation Workover Control Systems, Rig Surveys and Onshore/Offshore Testing

Support.

Flow Assurance is an integral part of FEED study, where steady-state and transient state

for single-phase or multi-phase flow plays a critical role. Well fluid conditions are a key

driver for selection of materials, production control system, system hardware selection

and topside process system design.

Patricia Water

Injection System Murphy

JP Kenny Malaysia was awarded the Patricia and

Serendah Pipeline and Subsea Pre-FEED study for

a Water Injection System. Based on Patricia Gas

Production draw-down by 2013, Murphy would

like a feasibility study that would introduce two

Water Injection Wells that would allow for

increased production. Processed water is pumped

from 13km to the Water Injectors; whereas, the

control system is located 1km away on the

Patricia Platform. The subsea control system

(MCS, EPU, TUTA, Umbilical, SUTA and Flying

Leads) ranges from simple direct hydraulics to

complex MUX systems. Nexus has been engaged

in developing a report that will examine an array

of field architectures, using proven technologies.

The Cost Analysis is to ensure that CAPEX and

OPEX are optimized and if a system is selected,

the well economics is favorable.
