Divers in marine construction are commercial divers who work underwater to support the building and maintenance of structures like bridges, ports, pipelines, dams, and offshore platforms. Their role blends diving with hands-on construction skills.

Core Responsibilities

• Underwater construction work: Assist in building structures such as piers, jetties, seawalls, and bridge foundations.
• Inspection: Check underwater parts of structures for damage, wear, or misalignment.
• Installation: Position and secure materials like concrete forms, steel beams, and pipelines.
• Repair and maintenance: Fix cracks, reinforce structures, or replace damaged components.
• Underwater welding and cutting: Join or remove metal parts using specialized tools.
• Rigging and lifting: Attach cables and guide cranes when heavy materials are lowered underwater.
• Survey support: Help engineers measure and map underwater sites before construction begins.

Types of Diving Used

• Surface-supplied diving: Most common for construction work, with air supplied from the surface.
• Shallow air diving: For less complex or near-shore tasks.
• Saturation diving (less common): Used for deep, long-duration projects.

Work Environment

• Harbors, rivers, dams, and offshore sites
• Often low visibility, strong currents, or polluted water
• Work from barges, boats, or temporary platforms
• May involve long hours and project-based schedules

Skills & Qualifications

• Certification from a commercial diving school
• Skills in construction trades (welding, carpentry, rigging, concrete work)
• Ability to read basic construction or engineering plans
• Strong physical fitness and stamina
• Knowledge of safety standards and underwater communication systems
