Project Overview

The HALO Maritime Defense System installation at Hamad Port Naval Zone in Qatar represents a high-security marine infrastructure project designed to protect critical naval assets. The project covered full offshore deployment, installation, alignment, and commissioning of an advanced floating maritime security barrier and access control gate system.


Project Location

Hamad Port Naval Zone – Qatar


Scope of Work

The scope of work included the following key activities:

  • Deployment of pre-cast concrete anchor blocks at approved GPS coordinates
  • Installation and alignment of warning and navigational marker buoys
  • Installation of the HALO floating maritime security barrier
  • Installation and commissioning of the retractable HALO security gate
  • Tensioning, alignment, and functional testing of the complete system
  • Final inspection and handover to the client


Mobilization & Preparation

  • Mobilization of marine crew, divers, lifting team, and safety officers
  • Transportation of anchor blocks, buoys, chains, shackles, and barrier units to the naval staging area
  • Pre-installation HSE induction and toolbox talks
  • Weather and tidal condition verification prior to offshore operations


Concrete Anchor Blocks Deployment

Equipment Used

  • Marine crane barge
  • Support vessels
  • Certified lifting slings and shackles
  • Professional diving team

Installation Procedure

  • Anchor blocks were lifted using a marine crane and transported to pre-approved GPS positions
  • Divers confirmed seabed conditions and alignment
  • Blocks were lowered under diver supervision
  • Final positioning was verified using DGPS and diver inspection
  • Underwater chain connections were secured and inspected

Outcome
All anchor blocks were installed within ±0.5m positional tolerance and designed to withstand environmental and operational loads.


  • Assembly of buoys with mooring chains and swivels
  • Deployment to designated positions
  • Diver-assisted underwater chain connections
  • Tension adjustment for correct freeboard and visibility
  • Inspection of reflective markings and navigation lights

Result:
A complete and clearly visible perimeter was established to ensure navigational safety.


HALO Floating Barrier Installation

  • Barrier modules transported by barge and connected section-by-section
  • Underwater chain connections installed by divers
  • Continuous alignment and tension control
  • Buoyancy, coupling, and stability inspections


Retractable Security Gate Installation

Installation & Commissioning

  • Positioning and alignment of the gate frame using a crane barge
  • Mechanical and structural fixation
  • Electrical and control system integration
  • Functional testing under operational load

Commissioning Tests

  • Remote operation test
  • Emergency stop functionality
  • Manual override verification
  • Sensor and limit switch calibration


  • Joint inspection with client’s engineering and security teams
  • Verification of alignment, tension, and system functionality
  • Submission of as-built drawings and maintenance documentation
