🌐 Helicopter Use in Underwater Cable Deployment – 5 Powerful Ways It Supports Connectivity

Helicopter use in underwater cable deployment improves logistics, crew support, and surveying. DreamSafar.in explains 5 powerful ways helicopters assist marine cable operations.

🚁 Helicopter Use in Underwater Cable Deployment – A Crucial Asset for Subsea Infrastructure

The helicopter use in underwater cable deployment is a vital but often overlooked part of large-scale connectivity projects. Whether it’s laying submarine internet cables or power transmission lines, helicopters play a key role in aerial surveying, equipment delivery, and crew coordination—especially in remote or offshore areas where ships alone aren’t sufficient.

In this post, DreamSafar.in explores 5 powerful roles helicopters play in underwater cable deployment projects across India and the globe.


🧭 1. Aerial Route Survey and Coastal Mapping

Helicopters are equipped with:

  • LIDAR systems for coastal elevation scanning

  • Multispectral cameras to identify ideal landing zones for cables

  • Thermal imaging to detect human and ecological activity near shore

✅ Speeds up the process of selecting the safest, least disruptive cable landing sites


⚙️ 2. Transporting Crew and Equipment to Remote Landing Points

Many subsea cable endpoints are:

  • On islands, coastal cliffs, or restricted-access areas

  • Too remote for trucks or conventional transport

Helicopter use in underwater cable deployment allows for:

  • Rapid movement of splicing teams

  • Delivery of lightweight power tools, drones, and cable markers


📦 3. Mid-Sea Support for Cable-Laying Vessels

While vessels lay the cable, helicopters:

  • Deliver urgent equipment or crew changes

  • Drop buoys, signal markers, or communication gear

  • Assist in airlifting injured personnel

✅ Especially useful in shallow waters or during rough sea conditions


🧯 4. Emergency Response & Safety Coordination

In case of:

  • Weather disturbances

  • Ship-to-shore cable tension issues

  • Accidents onboard

Helicopters serve as a safety and evacuation backup, offering:

  • Quick evacuation

  • Aerial situational awareness for ground and marine teams

  • Relay of real-time updates to onshore command centers


🔧 5. Infrastructure Monitoring and Project Documentation

Helicopters assist in:

  • Capturing aerial footage of the cable route

  • Monitoring coastal erosion or human interference post-deployment

  • Supporting regulatory compliance reports for MoEFCC and maritime bodies

✅ Footage is often used in public awareness, environmental audit, and final project delivery documentation


🌏 Real Projects Using Helicopters for Subsea Cables

Project Helicopter Use Highlights
Chennai–Andaman Cable (CANI Project) Coastal LIDAR scan, landing crew drop-offs
Lakshadweep Island Optical Fiber Link Emergency support + island site access
Mumbai–Singapore Submarine Cable Mid-sea supply drops + inspection
AP Transco Offshore Power Link (Vizag) Monitoring and deployment survey

💰 Cost of Helicopter Support in Submarine Cable Projects

Item Estimated Cost (INR)
Helicopter Survey Mission (per hr) ₹1.2 – ₹2 lakh
Equipment Transport Sortie ₹50,000 – ₹1 lakh
Emergency Backup Standby (per day) ₹1.5 – ₹3 lakh
Complete Cable Project Support ₹25 – ₹50 lakh (depending on scale)

✅ Often budgeted under “aerial support logistics” in marine infrastructure contracts


✅ Benefits of Helicopter Use in Underwater Cable Deployment

  • 🚁 Fast access to non-motorable terrain

  • 🌊 Ideal for island and offshore deployments

  • ⏱️ Reduces project delays caused by sea-only access

  • 📡 Enables real-time tracking and aerial surveillance

  • 🛟 Strengthens safety protocol and risk mitigation


❓ FAQ – Helicopter Use in Underwater Cable Deployment

❓ Do all subsea cable projects use helicopters?

Not always. Helicopters are used when the project involves remote access points, environmental monitoring, or emergency logistics.

❓ Are helicopters used during actual cable laying?

Indirectly. They support the vessels and ground teams by delivering equipment and providing aerial surveillance.

❓ Is it more cost-effective than sea-based logistics?

Yes, especially when time-sensitive crew movements, site access, or emergency response is required.
