Offshore renewable energy

Helix is committed to supporting the responsible transition from a carbon-based economy, increasing offshore wind and reduced emissions technology.

Offshore renewable energy covers a diverse range of technologies and include the fundamentals of harnessing wind, wave and tidal power and turning it into useable electricity. This power is then taken ashore for domestic use. Excess power is now being traded between counties via a network of subsea power cables.

Offshore wind currently dominates the renewable industry, covering all aspects of marine construction and will involve more and more offshore contractors to support the industry’s growth requirements as these wind farms move into deeper waters.

Helix is applying the techniques and technologies proven in offshore oil and gas fields to the needs of this rapidly growing industry.

Bespoke burial ROV systems like the T1500, T1200 and i-Trencher provide seabed jet trencher from state of art support vessels like the Grand Canyon II and III which are optimized for work in the relatively shallow, fast-moving waters typical of offshore wind farm fields.

These bespoke assets are delivering new levels of operational performance in wind farms throughout Europe, reducing project time and enduring harsher environments than previously possible as well as burying the cables associated with such infrastructure deep into the varying soil condition present at an offshore site.

The capabilities of these installation support systems are continually evolving with the industry, ensuring Helix can continue to provide a high level of renewable energy development expertise and performance to support its clients and the developers of offshore renewable projects.

The Offshore Renewable Sector is split into 3 distinct areas:

  • Offshore Wind Farms (OWF inter array cables)
  • Power Transportation from OWF to Shore (Export Cables)
  • Power Sharing between countries (Inter-Connectors)

Helix has an excellent reputation for providing burial and construction support solutions in all 3 areas.

We are exploring the expansion of our niche burial offering to add other complementary services, additional subsea services now being delivered are;

  • Near shore and offshore UXO survey/clearance
  • Near shore and offshore Boulder relocation/removal
  • Mattress installation/removal
  • Scour protection
  • Wet & dry inspection testing for corrosion & fatigue
  • Installation support, both inshore & offshore
  • Route preparation
  • Engineering (embedded & consulting)
  • Cable repair
  • Decommissioning

Our experience runs deep

At the end of field life, your primary goal is to leave behind a clean seabed, so that our seas and oceans are safe to be sustainably used by others for centuries to come.

We’re here to support you, to the letter.

We understand the challenges posed by subsea construction and diving operations in the harshest conditions and with the most complex subsea assets.

Our modern, DP3 Grand Canyon class fleet means you have access to nimble, flexible services.

Our class-leading trenching assets and advanced subsea robotics services means you can trust in getting the best and most efficient service.

The understanding and experience you need

Combined with our deep, global knowledge of seabed soil conditions, you access the understanding and experience you need.

From cable trenching and burial to subsea architecture removal, we will complete your seabed clearance projects safely, efficiently and cost effectively,

In every project we do for you, we combine our engineering and program development support with our offshore operational expertise.

We bring the in depth knowledge of local and global regulations and best practise, so that your operations are completed on time and without incident.
