ENGINEERING RECORDS GUIDELINES

Responsibility of Engineering Records Focal point/ Document Controller

Focal point of all issues related to Engineering records/ documents (drawings and reports)

Develop and maintain engineering record database, recording and registering engineering numbers allocated and actually used in the field. The database shall include numbers of all existing drawings, equipments, tags, line, cables; project codes allocated and plants documents number. The database shall include all necessary details, type, location, date installed, etc.

Responsible to allocate/ assign and issue of Numbers for Drawings, Equipment, Line, Cable and Tags (including vendor documents).

Responsible to allocate/ assign and issue of Area Codes and Plant/ Unit Codes Responsible to assign Project codes for new projects Initiate and follow up As built after successful completion of construction work ensuring

that Master drawings are updated to reflect the latest site changes Storage and safekeeping of Master Drawings and engineering documents, maintaining

hard and electronic (AutoCAD files) copies Update engineering numbering database for the actual numbers and drawings used by

a project

Engineering Drawings

These are engineering master drawings produced by and for Daleel Production Station (DAPECO). Drawings could be produced by engineering consultant/ contractor or vendor/ equipment manufacturer. Master drawings should always represent the current facility status, as built status, at all time.

Master Drawing

Master drawing is a drawing, which represents the facility as constructed. Master drawing shall be kept updated whenever a change occurs to the facility. Master drawing should always be updated and as built after any construction, modification or replacement activity.

Project Drawings

Project drawing is a drawing prepared based on the master drawing for a specific project reflecting the proposed new facility or modification/ upgrade to existing facility. The project drawing will have the same master drawing number but in addition a project code is introduced with the drawing number to distinguish between master and project drawings.

When a project is identified and initiated, copy of the applicable existing master drawing(s) requested from the drawing controller/ drawing office. Copy of the master drawing(s) shall then assigned with a specific unique project identification code known as project code. All project drawings shall clearly indicate the project code. After the implementation of the project one set of the project drawing is used to prepare mark up of the actual constructed

of 4/tt/file_convert/5695d4e01a28ab9b02a321bd/document.doc

modification (red line mark up). The red line mark up is then forwarded to project engineer and drawing controller/ drawing office to as built the master drawing.

Identification and Numbering of Engineering Drawing(s)

All drawings will have an identification number. The drawing number consists of the following: 1) Area Code, 2) Engineering Discipline code, 3) Drawing serial number, 4) Drawing sheet number, 5) Project Code, 6) Drawing size, 7) Revision.

1) Area:

Field name i.e. Daleel. Currently Daleel Petroleum Company has only one field (Daleel)

2) Sub area:

Facility under the a particular area, i.e. Production Station, Satellite Manifolds, well heads, etc.

3) Sub area number: A two digit number identifying code number for a particular sub area: Sub area code number 11 is allocated for Daleel Field (Satellite Manifolds, Well Heads

and Water Injection) Sub area code number 12 is allocated for Daleel Production Station Sub area code number 13 is allocated for Lact Unit Sub area code number 14 is allocated for Mazoon Sub area code number 15 will be allocated for the B Block new facilities at Satellite

Manifold 4 Sub area code number 16 will be allocated for Water Supply Well heads

4) Area Code:

The Area Code is a three alphabetic character designation of an area or oil field. It is a short of the area or field. Area Code ‘JPX’ (short for Japex) is currently the area code used on drawings and

documents to represent the Daleel Field. This covers Daleel Production station and Daleel Field (well heads and Sattellite Manifolds-SM). JPX will be maintained on these areas.

For all new areas the new Area Code shall be ‘DAL’. New areas will cover B Block Facilities at SM-4 and Water Injection Facility, Water Supply System and Mazoon Field.

DAL will not used on existing drawings and areas as it will involves a lot of drawings and documents modification.

5) Engineering Discipline Code:

The Engineering Discipline Code is a single numeric character indicating the engineering discipline the drawing belongs to: ‘1’ is for Multidiscipline drawings e.g. Plot plans, PFS, PEFS, etc. ‘2’ is Civil discipline ‘3’ is Piping/ Mechanical


‘4’ is Electrical ‘5’ is Instrumentation ‘6’ is Telecommunication ‘7’ is Cathodic protection ‘0’ is Demolition

6) Drawing Serial number :

The drawing serial number is a four digit sequence number.For B Block drawing numbers shall start from 1001, as the 1000 block will be dedicated for B Block Gathering Station.For Mazoon development will allocated with another block of number i.e. 2000.

7) Drawing Sheet number:

Three digit sequential number related to the main drawing covering the same subject.

8) Project Code

This is a unique identification code (named as Project code) allocated to a particular new facility or modification or upgrade to existing facility within an sub area. The project code is two alphanumeric character code (from A1 to Z9). The project number shall always be included in project drawing numbering and document numbering forming the project drawing/ document identification number therefore the choice of alphanumeric code instead of fully numeric code. Project code is used to clearly differentiate master drawings and documents from project drawings/ documents and it identify the project.

9) Revision number

Each issue of modified drawing shall have a different revision number to distinguish between different issues.

10) Drawing Size

A0, A1, A3, A4

Engineering Numbering

Plant/ Unit number:

A two digit identification number unique to a plant. This number always form the first two digit of the plant engineering numbers i.e. equipment, tag, line, cable and instrument numbers.

Unit Code number 11 is allocated for Daleel Field (Satellite Manifolds, Well Heads and Water Injection)

Unit Code 12 is allocated for Daleel Production Station Unit Code 13 is allocated for Lact Unit Unit Code 14 is allocated for Mazoon Unit Code 15 is allocated for the B Block facility Debottlenecking Unit Code 16 will be allocated for Water Supply Well heads


Equipment/ Line/ Tag/ Cable Numbering

Equipment/ Tag/ Line / Cable numbers consists of three section; plant code, category of the equipment (alphabetic letters), serial number of that particular type of equipment/ instrument, line or cable.

A database will keep record of the used and available numbers.

Change Control

Changes to the as built drawings and documents could be caused by either 1) a project or 2) field change, modification initiated by site operations.

1) Changes by a project

These are planned facilities modifications or upgrade. After completion of a project the Construction Contractor along with the company representative shall prepare as built red line mark up indicating the changes during construction. The redline mark up shall include changes to the coordinates and elevations.

Redline mark up shall be forwarded to the Project engineer and Drawing record controller to initiate as built exercise and update the master drawings.

2) Changes by Field Modification/ Change

These are field modifications or changes due to site problems, integrity or operational improvement. Any such modification shall be recorded and as built mark up on relevant drawings for as built. Any new equipment, tag, line, cable number shall be requested from the engineering record focal point.

The as built mark up shall be forwarded to the Engineering Document Controller/ Engineering Document Office.

Engineering Document/ Drawing Storage

All engineering documents/ drawings shall be stored as electronic files as well as hard copies. Copy of the electronic files (read only) shall be stored on the company server under dedicated directory and on CDs kept in a safe area in the office. Hard copies of all the documents of each document/ drawing shall be kept in a safe area.
