    Subsea Wellhead Systems

    Subsea wellhead systems are made up of wellheads mounted on the seabed that are connected by piping systems. Considering the environment in which these systems are installed, they are comprised of highly reliable hardware components to ensure the integrity of the systems. Subsea systems also require high integrity power systems which ensure that the proper levels of energy are provided to operate the subsea wellhead hardware. This course will provide participants with the necessary knowledge to demonstrate the principles of subsea wellhead systems and associated equipment.

    Course attendees will learn how subsea wellhead systems are developed and how the hydrocarbons are gathered and brought to the surface for collection. They will become familiar with the power and control systems used in subsea wellhead systems and will be exposed to the various parts used to connect multiple subsea wellheads.

    Participants will learn about the operation of the subsea wellhead and the christmas tree, as well as learn about managing risk and making subsea wellhead systems more reliable.

    Day 1

    Subsea Wellhead Systems

    • Subsea field development
    • System architecture
    • Subsea distribution system
    • Component design parameters

    On day one, participants will learn about how a subsea field is developed and the requirements needed to determine if development is a viable option.  Once a field is established as viable the requirements for the subsea field are determined.  Participants will be exposed to the makeup of the gathering and distribution system required to collect the hydrocarbons and the process of bringing them to the surface for treatment and storage.

    Day 2

    Subsea Wellhead Control

    • Types of control systems
    • Topside equipment
    • Subsea control module
    • Subsea power system

    Participants will learn about the control system, as well as the safety and protection systems required to operate a subsea wellhead system.  Participants will gain knowledge of the interface between the subsea wellhead system and the topsides where the control functions are performed. Then the focus this day will be directed towards the reliability and integrity required from the hardware components, as well as power systems given the nature of the operating environments.

    Day 3

    Subsea Equipment

    • Subsea manifolds components
    • Manifold design and analysis
    • Installation of subsea systems
    • Pipeline ends and in-line structures
    • Subsea connections and jumpers

    Participants will learn about the different types of hardware found in a subsea wellhead system on the third day. The equipment that makes up the subsea wellhead, piping manifolds, piping connections, and jumper lines will be covered. The participants will also learn about the hardware required to bring the hydrocarbons to the topside facility.

    Day 4

    Subsea Wellhead Completions

    • Subsea completions
    • Subsea wellhead system
    • Subsea christmas tree
    • Subsea risk and reliability
    • Safety considerations and environmental impact assessment

    Once the participants have an understanding of the required hardware components, they will learn about the installation and connections required to build a subsea wellhead system.  The participants will be made aware of installation procedures required for subsea completions which involve securing the equipment to the sea floor.  The course concludes with a discussion of the risks and safety considerations of installing and operating subsea wellhead systems and operations of these systems in a reliable manner.

    This course is mainly targeted to process operators, process technologist laboratory and maintenance personnel, immediate supervisors to the working technicians, as well as employees working with equipment and materials purchasing, equipment procurement, and job planning.

    Participants should have some recent exposure to subsea wellhead terminology.
