Loss Prevention

Plays a pivotal role in explosion prevention – i.e. the technique of preventing explosions due to flammable gases, vapours, mists, dusts and etc. It refers to the classification of plant into hazardous areas, and the systematic identification and control of ignition sources. The starting point is to identify sources of release of flammable gas or vapour arising from normal/ unplanned operation. Classification of hazardous areas aid the selection of appropriate zone type and equipment, the remainder will be defined as non- hazardous, sometimes referred to as ‘safe areas’, in accordance to industrial standard such as API 505 or EI 15.

Firewater system related studies include firewater hydraulic demand calculation (steady state) and firewater surge analysis (transient) using licensed Sunrise Pipenet software.
The demand calculation will be performed in accordance with international standards (e.g. NFPA), considering the optimal location/ quantity/ coverage and pressure sufficiency of firewater users (i.e. firewater sprays, monitors or hydrants).
The surge analysis, on the other hand, considers the surge pressure involved in plausible transient scenarios, such as the opening/ closing of a deluge valve or starting of the firewater pumps. The anticipated pipe stresses will then be compared against the piping specification to ensure design safety.

The objective of the study is to assess adequacy of the fire and gas detection system based on international codes and standards. The assessment considers the material properties, redundancy provided the F&G detectors as well as blocking of line of sight. Where deemed necessary, suitable practicable recommendations will be made to improve the fire and gas detection system performance.

RAM Study is to be undertaken based on the production profile for full field life, including future expansion of equipment, components, and systems using a life-cycle performance simulation software package (MAROS) to determine Production Availability and Production Efficiency. The RAM model will include definition of the potential constraints on repair activities imposed by restrictions such as flaring limitations, mobilisation delays, shift constraints, resource limitations and capital spares availability. The assessment will also identify the main failure components and if necessary recommend modifications to the design to help improve the overall system availability.

A Failure Modes and, Effects Assessment (FMEA) is to be undertaken as part of the RAM Study to identify potential failure modes and their criticality in terms of impact to operations. The FMEA worksheet will include identification of potential system failure modes. The failure and repair data for each equipment/item will be estimated based on the statistical data applicable to offshore from reputable Contractors, field operators or recognised international bodies, recognised international standards and practices such as OREDA.

Mechanical Integrity (MI) can be defined as the management of critical process equipment to ensure it is designed and installed correctly and that it is operated and maintained properly. Mechanical Integrity encompasses the activities necessary to ensure that equipment/assets are designed, fabricated, installed, operated and maintained in a way that provides the desired performance in a safe, environmentally protected, and reliable fashion. Mechanical Integrity is considered aligning with Engineering asset management (EAM), which means management of engineering assets and provides guidelines on the effective usage of all the physical engineered assets within the organization. Scope of services includes:
– Asset Hierarchy Development
– Maintenance Strategies & Maintenance Plan
– Development of Bills of Material
– CMMS Review
– Maintenance Work Process Review
– Warehouse Stock Holding Review
