From hazard identification and permit systems to emergency response and incident investigation, every topic is built for real offshore conditions. Get certified, stay compliant, and protect yourself and your crew.

Dedika for businesses

What you will learn:

You will cover the full scope of offshore and barge safety, starting with regulatory frameworks, PPE standards, and safety culture fundamentals. From there, you will work through risk assessment methods, permit-to-work systems, and process safety barrier models for hydrocarbon control. Fire prevention, firefighting techniques, and structured emergency response procedures are covered in detail. Marine operations topics include barge stability, mooring systems, and vessel transfer safety. Occupational health, fatigue management, and incident investigation round out the core training. Supplementary modules address working at height, diving operations, environmental compliance, and digital safety tools.

    Introduces leading and lagging indicators used to monitor process safety health. Enables students to interpret data and escalate deteriorating barrier performance.

  • Lesson 4 • Process Safety Barrier Model

    Introduces the bow-tie barrier model applied to hydrocarbon containment and loss-of-containment scenarios. Establishes the conceptual foundation for all process safety topics.

  • Lesson 5 • Hydrocarbon Release Prevention

    Covers pipeline integrity, pressure relief systems, and corrosion management to prevent unplanned releases. Links engineering controls to barrier model concepts.

Chapter 4See details

Fire Prevention and Firefighting

  • Lesson 1 • Structural Fire Prevention Measures

    Addresses passive fire protection, fire and blast walls, and fireproofing standards for offshore structures. Reinforces the layered barrier approach from Chapter 3.

  • Lesson 2 • Offshore Fire Response Procedures

    Outlines alarm response, fire team roles, and coordinated attack and withdrawal procedures. Integrates fire science and equipment skills into a structured response sequence.

  • Lesson 3 • Fire Science and Offshore Ignition Sources

    Reviews combustion chemistry, fire classes, and ignition sources specific to offshore assets. Grounds firefighting decisions in physical and chemical principles.

  • Lesson 4 • Portable Firefighting Equipment

    Covers selection, inspection, and hands-on use of portable extinguishers and hose reels. Builds practical skills for first-response fire control.

  • Lesson 5 • Fixed Fire Suppression Systems

    Explains deluge, foam, CO2, and dry chemical fixed systems installed on platforms and barges. Connects system design to the hazard zones identified in Chapter 3.

Chapter 5See details

Emergency Response and Evacuation

  • Lesson 1 • Emergency Management Structure

    Defines the offshore emergency command hierarchy, roles, and communication protocols. Establishes the organisational framework for all emergency response actions.

  • Lesson 2 • Survival Craft Operations

    Trains students in lifeboat and life raft deployment, boarding, and operation under adverse conditions. Builds on muster procedures to complete the evacuation sequence.

  • Lesson 3 • Muster and Headcount Procedures

    Covers muster station assignments, headcount accountability, and missing-person protocols. Ensures every worker can fulfil muster duties during any emergency scenario.
