Cable Operations & the Environment

In the dynamic and ever-evolving field of oceanography, Subsea Marine Services offers expert services AND environmental stewardship. As veteran providers of marine fiber optic cable and survey services, we understand the critical balance between efficient operations and ecological responsibility. In this context, the installation of undersea cables, a backbone of global communication and data transfer, demands not only technical expertise but also a deep commitment and consideration for the environment.

The Importance of Undersea Cables

Undersea cables are the unsung heroes of international connectivity, carrying over 95% of the world's data traffic. These cables, traversing thousands of miles across ocean floors, are crucial for everything from internet and telecommunication services to scientific data exchange. The seamless operation of these cables is integral to our modern, interconnected world.

Environmental Challenges in Cable Installation

The installation of these cables, however, is a complex task that intersects with various environmental concerns. The ocean floor is a diverse and sensitive ecosystem, home to a multitude of species and natural habitats. Disturbance of these ecosystems can have far-reaching consequences. Therefore, it is imperative that companies like Subsea Marine Services approach undersea cable installation with a comprehensive environmental strategy.

Route Planning and Environmental Impact Assessments (EIA)

The first step in mitigating environmental impact is thorough route planning and conducting comprehensive Environmental Impact Assessments (EIA). These assessments evaluate the potential effects of the cable installation on marine life, the seabed, and the broader ecosystem. Factors such as the presence of endangered species, marine protected areas, and sensitive habitats are taken into account. This stage often involves collaboration with marine biologists, environmental scientists, and regulatory bodies to ensure that the chosen route minimizes environmental disturbance.

Cable Laying Techniques and Technologies

Advancements in cable-laying techniques and technologies play a pivotal role in reducing environmental footprints. Subsea Marine Services utilizes state-of-the-art ships equipped with dynamic positioning systems to precisely lay cables without unnecessarily disturbing the seabed. Remote Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs) are employed for accurate placement, especially in ecologically sensitive areas. Additionally, we are constantly exploring innovations in cable design to enhance durability while minimizing ecological impacts.

Sediment Disturbance and Turbidity

The process of laying cables can stir up sediment on the ocean floor, leading to increased turbidity which can affect marine life, particularly filter feeders and coral reefs. To address this, we employ techniques such as jet plowing, which involves using water jets to create a narrow trench for the cable, significantly reducing the amount of disturbed sediment. Moreover, constant monitoring during the installation process allows for immediate adjustments to minimize turbidity.

Electromagnetic Fields (EMFs) and Marine Life

Electromagnetic fields generated by undersea cables have raised concerns regarding their impact on marine life, especially species that are sensitive to electromagnetic changes like sharks and rays. Ongoing research and monitoring are essential in understanding and mitigating these effects. Our approach includes using cable shielding techniques and monitoring marine life behavior in the vicinity of the cables post-installation to assess any long-term impacts.

Noise Pollution

The installation process can generate noise, which has the potential to affect marine mammals and other wildlife. Subsea Marine Services employs noise reduction strategies such as using low-noise equipment and restricting operations to certain times to minimize the impact on sensitive species. Additionally, we engage in continuous monitoring of noise levels and adhere to international guidelines and regulations regarding underwater noise.

Collaboration with Regulatory Bodies and Stakeholders

Collaboration with regulatory bodies, local communities, and other stakeholders is vital. We ensure compliance with national and international environmental regulations and engage in transparent communication with all stakeholders. This collaboration often leads to better outcomes for both the environment and the project.

Post-Installation Monitoring and Maintenance

After the installation of undersea cables, ongoing monitoring and maintenance are crucial. Regular inspections are conducted to assess any potential environmental impacts and to ensure the integrity of the cables. This proactive approach not only helps in early detection of issues but also contributes to the longevity and reliability of the cable network.

Conclusion

At Subsea Marine Services, our commitment to environmental stewardship is as strong as our dedication to service excellence. We recognize that the health of our oceans and the success of our operations are intrinsically linked. By integrating environmental considerations into every stage of undersea cable operations, we not only protect our precious marine ecosystems but also ensure the robustness and reliability of the global communication network. As we move forward, we continue to innovate and adapt, always with an eye towards a sustainable and connected future. Environmental considerations in undersea cable installation are not just a responsibility but a cornerstone of our operations.
