This Asset Life Study includes an assessment of the condition Company assets. The study also aims to identify the recommendations and actions as well as estimated costs necessary to maintain the assets for a further years of operation .

The methodology adopted for the life study includes:

1. Review of documentation relating to design parameters

2. Assessment of criticality of the assets

3. Review deterioration and other life-limiting mechanisms

4. Review of inspection / maintenance / RBI records

5. Discussions with operation team

6. Overview visual inspection

The information from these reviews was used to carry out a categorisation of the assets.

Cost estimates for upgrading and replacement works have been produced, taking into account achieved cost data from the plant and the database from Software.

A key part of the study was to determine the physical condition of the Assets.

The study considered materials of construction issues, including assessment of deterioration rates for equipment components. The study is not intended to conduct detail root cause analysis for specific issue. However, as part of the study, any applicable area of improvement observed will be highlighted in the report.

In order to accomplish the assignment, thermal design was conducted by using HTRI and EDR software to estimate weight and footprint of the heat exchangers.

Plate and Shell Heat Exchanger (PSHE) delivers small footprint with efficient heat transfer.

Air conditioning heat load calculation :
The HVAC cooling loads are calculated in accordance with ASHRAE to size up for the following equipment and their characteristics:-
i. ACCU cooling capacity.
ii. ACCU on-coil and off-coil temperatures.
The calculation is performed using Carrier E-20 Hourly Analysis Program
(HAP) and checked by Camel software.

Tie-ins and modifications to existing facilities (e.g. piping, electrical,
instrumentation, structural)

A fired heater is a source of heat at high temperature, above 500°F. It is a high cost item, in terms of
installed cost, operating and maintenance cost, and the amount of operator attention required. Furthermore, it is potentially one of the more hazardous items of equipment in a facilities. Once constructed, it is difficult and expensive to alter. Before a fired heater is chosen for a given application, alternatives should be considered.

A fired heater is a source of heat at high temperature, above 500°F. It is a high cost item, in terms of
installed cost, operating and maintenance cost, and the amount of operator attention required. Furthermore, it is potentially one of the more hazardous items of equipment in a facilities. Once constructed, it is difficult and expensive to alter. Before a fired heater is chosen for a given application, alternatives should be considered.
If the process stream is at a low temperature, it can be preheated by exchange with other streams. If the final temperature is to be in the 450-500°F range, consider available steam supplies. If the required duty is modest, this requirement can be combined with others in a hot oil system. If the duty is very small, electric heating may be attractive.
Fired heaters in producing operations include line heaters for preventing hydrate formation and assisting oil-water separation. These heaters are considerably smaller and cheaper than those in process plants. They may be automated for unattended operation. “Fire tube” designs are common, and heating may be direct or indirect.
The absence of central steam systems frequently justifies the use of these fired heaters. Show less

Mechanical Integrity (MI) provides assurance that physical hardware barriers (Safety Critical Element – SCE) are in place and working:
to prevent initiation or escalation of major incidents or,
if they are not, that risks are appropriately addressed and mitigating action taken

MI program provides assurance that asset integrity is safeguarded for continued service.

This report presents the findings of a predictive noise modelling and acoustically induced vibration (AIV) analysis of high noise-emitting equipment associated with . The aim of this assessment is to provide noise allocation limits to individual items of equipment, in order that the plant meets the occupational noise standards established for the Project and to determine if any pressure reducing device requires design modification due to high acoustic energy with the system.

The objective of this study is to identify the potential critical lines regarding FIV throughout the facilities and to recommend actions to reduce either the sources of turbulence or the response of the critical lines.

Indirect water cooling (PCHE) option offer better cooling performance, less noisy, compact size, higher reliability and lower capital cost.
Recommended cooling for compressor discharge are through indirect water cooling using printed circuit heat exchanger. Main reasons are as the followings:
a- Smaller size with more flexibility for equipment layout.
b- Lower equipment cost with significant cost reduction through savings in structural steels.
c- Improve safety, easy installation, and increase process responsiveness due to compact size and design.
d- Small inventory which lead to savings in design pressure rating, reduce flare capacity and blowdown load.
e- Improve safety, easy installation, and increase process responsiveness due to compact size and design.
