    About this ebook

    When working on oil and gas offshore projects the 3D layout is one of the most essential parts according to Jacques Daubian, author and engineering and construction specialist. The objective of the company during the engineering and construction phases is to deliver the project on time and safely to the field operators and to ensure everything will be maintained safely, during the life of the offshore operations. 
    All major oil and gas companies and contractors use 3D software for the design, layout, drawings and procurement of their projects. Each 3D model must be perfect during the detail engineering to be able to extract all the information necessary for the construction. The layout of offshore oil and gas projects start day one of the basic engineering and everything must be fixed before the completion of 50% of your detail engineering to avoid any engineering problems and delay during construction.The layout using 3D software is today an obligation. 
    Jacques Daubian latest book The New 3D Layout for Oil & Gas Offshore Projects will aid projects struggling with their 3D model layouts as well as those simply looking for a new and more effective approach. The book includes a checklist, listed by discipline, of what must be done to ensure the success of your project. Jacques Daubian draws on personal experience within the engineering and construction industry to provide an informative and helpful guide. For 12 years Jacques Daubian examined the huge degradation of the layout aspect of offshore projects and has since re-evaluated this, as demonstrated in The New 3D Layout for Oil & Gas Offshore Projects.

    The New 3D Layout for Oil & Gas Offshore Projects - Jacques Daubian

    Glossary

    Introduction

    The layout is probably one of the more essential parts of offshore oil & gas (O&G) projects and can impact everything and all disciplines during engineering and construction as well as the CPY field operations (OPS) during offshore operations. The principal reason is the very tight space available on offshore oil & gas (O&G) projects.

    The objective of the company (CPY) during the engineering and the construction (CTR) phases is to deliver the project on time and safely to the field operators (OPS) and ensure they will be able to maintain everything safely during the life of the offshore operations.

    The layout has schedules, rules and steps and if you start too late to review the layout you will have major risks during all of your engineering and construction phases. There may also be problems for the CPY field operations (OPS) and high cost for the company (CPY) and the contractor (CTR).

    The layout of offshore oil & gas (O&G) project(s) starts on day one of the basic engineering and everything must be fixed before the completion of 50% of your detail engineering to avoid any engineering problems and delay during construction.

    The layout using 3D software is today an obligation. Oil & gas (O&G) major companies (CPY) and the contractors (CTR) are all using 3D software for the design, layout, drawings and procurement.

    The 3D model of the project must be perfect during the detail engineering to be able to extract all the information necessary for the construction and must be approved by the company (CPY) in the same manner as official documents. The 3D model is deliverable from the contractor (CTR).

    Implemented in the information you will find in my book in the company (CPY) specifications and in the contractor (CTR) are the internal 3D procedure(s) that will help your projects. You will have a checklist by disciplines for what you must do and must not forget for the layout of your projects.

    I consider the CONTRACTOR as the ENGINEERING Company in this book.

    The layout is a long job that needs to be followed closely during the detail engineering by the company/contractor (CPY/CTR) and where all must be methodical.

    Chapter 1

    CPY Contract, CPY Specifications and CPY & CTR Organisation

    1.1 – CPY Contract

    I am not a contract specialist, but I advise you to add or to be sure that you have the points below in your contract with your CTR.

    1.1.1 – Basic Engineering

    The CTR will use the 3D software requested contractually by the CPY (PDS, PDMS or SM3D).

    The software NavisWorks will be used for all 3D model reviews official or specifics and without exception.

    3D model review every week with the CTR and the CPY including comments and closeout will be managed using the software NavisWorks.

    3D model for internal CPY reviews (NavisWorks file) will be given to the CPY every week by the CTR and more often if necessary the first week after the CTR starts the 3D model.

    Mechanical handling (MH) will be modelled in the 3D model and show all volumes like access ways, turning radius, handling equipment for the major valves and equipment or skids or packages.

    Clear and comprehensive management of change (MOC) must be used from day one and be able to keep the history.

    1.1.2 – Detail Engineering

    The CTR will use the 3D software requested contractually by the CPY (PDS, PDMS or SM3D).

    The software NavisWorks will be used for all 3D model reviews, official or specifics and without exception.

    Permanent 3D model review with the CTR and the CPY and during the full detail engineering if necessary including comments and close out will be managed using the software NavisWorks.

    The 3D model for internal reviews (NavisWorks file) will be given to the CPY every week by the CTR and more often if necessary the first week after the CTR starts the 3D model.

    The CTR should use one unique and same database for engineering and construction (sometimes, it is impossible depending on the CTR, eg., Samsung Heavy Industry in South Korea. They use two databases and different software between the engineering and construction. You can understand that without perfect control of these different systems it can be a major risk for the project).

    MH will be modelled in the 3D model and show all volumes like access ways, turning radius, equipment, valves, handling equipment, etc.

    All necessary volumes will be modelled in the 3D model, like doors opening, gas detection between receptors, cones for sprinklers (deluge system for equipment, skids or packages), all access ways (primary, secondary, operation), etc.

    Clear and comprehensive MOC must be used from day one and able to keep the history.

    1.2 – The CPY Specifications

    VERY IMPORTANT AND THE CPY NEEDS TO BE VIGILANT. If you specify in the CPY specifications a minimum access way with a value, please remove this information from your specifications.

    I saw in different specifications a minimum access way of 700mm used generally for the CPY OPS. This information does not mean ANYTHING, and the CTR will use this specification to make everywhere 700mm clearance and it will not work!

    If you want to write in your specifications the minimum distance for an access way, you should follow my advice and definition:

    A minimum distance in between items for an access way is the clearance the CPY will need for the mechanical or valve handling (MH or VH) of the bigger item in this way, including 150mm clearance for items equal to or less than five tonnes and 300mm clearance for items more than five tonnes in each side of the handling equipment will need the CPY to transport this item (you can modify the clearance 150mm for items maximum 5T and 300mm clearance for items more than 5T but try to keep these distances and weights).

    If the CPY does not have any MH or VH in this way, the minimum distance in between items will be 800mm clearance (this is an example for the distance but try to keep this value. Remember that for oil & gas offshore projects an access without MH or VH does not exist; you always have something).

    Example:

    Two piping lines parallel where the bigger item is ESDVs with actuators and less than five tonnes. The minimum distance in between these piping lines will be the size of the trolley OPS will need to remove the larger ESDV + 150mm each side (considering you will use a permanent monorail(s) above the ESDV to pull down this valve on the
