Engineering

Engineering service is the technical foundation of all services provided by ISSAC E&C.

ISSAC E&C utilizes theoretical knowledge and field experience in a complementary manner to create improvements that can save time and costs in familiar types of construction, and to develop methodologies that can solve complex technical challenges in new and challenging construction projects.

Noise/Vibration Measurement & Analysis

Basic Design

We provide basic design for small to medium-scale onshore/offshore plant projects. Based on conceptual designs that can meet customer requirements, we review feasibility, analyze potential risk factors in advance, and reduce the possibility of design changes.

Basic design mainly checks the following items.

Conceptual process studies (material balances, process flow sheets,…) and preliminary plot plan

Preliminary piping and instrument diagrams

Definition and sizing of main equipment resulting in process specifications

Specification of effluents

Definition of control and safety devices

Thermal rating of heat exchangers

Preparation of tender packages for the main equipment

Development of process and utility piping and instrument diagrams released for detail engineering

Development of detailed plot plans and hazardous areas

Elaboration of the main piping, instrument, electrical and civil works layouts

Maintenance &
Inspection Engineering(MIE)

Maintenance and Inspection Engineering (MIE) refers to a series of technical management systems that analyze and document all information necessary for operation and maintenance prior to the operation of onshore/offshore plants. Based on data produced through the MIE process, maintenance and inspection work management is computerized (CMMS) to ensure efficient and safe plant operation.

Main service items of MIE (Maintenance and Inspection Engineering)

RAM(Reliability, Availability and Maintainability) analysis

RCM(Reliability Centered Management) analysis

RBI(Risk Based Inspection) analysis

Spare parts analysis

M&I plan

CMMS and CIMS implementation

Organization management and procedures development

Commissioning
Engineering

Commissioning engineering refers to a series of preparatory work that plans, analyzes, and documents in advance the elements necessary for commissioning to proceed in a manner that meets certification conditions and is safe, efficient, and systematic.
Harmonious collaboration of highly specialized commissioning engineers is essential, and if this process is faithfully carried out, subsequent commissioning can also proceed efficiently. This process is divided into Pre-commissioning and Commissioning stages, similar to commissioning, and the general work and deliverables performed at each stage are as follows.

Pre-commissioning Engineering

The work and deliverables performed in the pre-commissioning engineering stage are as follows.

Activities

Population of the pre-com database in PCS

Review and update of the pre-com check and test sheets

Preparation of the pre-commissioning planning

Preparation of the pre-commissioning dossiers to be filled in during the Pre-com execution phase

Prepare and issue the pre-com management procedures

Prepare and issue the pre-com procedures

Prepare and issue the pre-com progress report format

DOSSIERS

RFC certificate and RFC punch list

Sub-system limit marked-up drawings (ie P&IDs, SLDs, loop drawings)

Pre-commissioning status index and check/test sheets per discipline

Pipe work flushing, cleaning, drying, leak test testing and inerting reports

Equipment inspection and survey reports

RFC preliminary check reports per discipline

First fill chemicals schedule

Preservation schedule

Vendor report

Commissioning Engineering

The work and deliverables performed in the commissioning engineering stage are as follows.

Activities

Validation of the subsystem breakdown and sub-systems limits

Definition of the commissioning databases

Population of the commissioning database in PCS

Definition of the punch list database format

Prepare and issue the start-up sequence

Prepare and issue the commissioning planning

Preparation of the commissioning manpower (including assistance by vendors and construction contractor)

Preparation of the commissioning mobilization plan

Preparation of the management procedure

Preparation of the procedures

Preparation of the operational tests procedures

Noise/Vibration Measurement & Analysis

Excessive noise and vibration generated during ship operation reduce the performance and durability of ship systems and are harmful to the human body.
ISSAC E&C performs services to measure and analyze noise/vibration to identify the cause of occurrence.

Main service items
