Seabed Preparation

Combining expertise with the latest remote technology to offer powerful, cost-effective, and flexible deployment platforms

Boulders and debris can pose a significant challenge for developers, potentially leading to extensive layout alterations and rerouting; adding considerable time and expense. 

Our expanded capabilities include UXO search and identification, disposal and relocation, as well as Free From Explosive (FFE) and As Low As Reasonably (ALARP) Certification Services.

Our industry-leading techniques offer a highly efficient solution to the challenge of boulder relocation, UXO search and identification, and debris clearance onsite.

Boulder Relocation and Removal

Subsea Multi-Tool (SMT) ROV

Applying our years of experience, we created the Subsea Multi-Tool (SMT) ROV; a powerful, cost-effective and flexible deployment platform capable of satisfying various subsea requirements.

The modular design allows for interchangeable tooling, including a 6-tine grab, clamshell grab, mass flow excavator and survey skid. The system offers superior productivity in comparison to a WROV, operating effectively even in high-current environments. With flexible deployment options, the SMT-ROV is capable of relocating 140+ boulders in a 24hr period, depending on the boulder density and deployment method. 

Deployment Methods

  • Vessel AHC crane deployment with tagging tower
  • A-Frame LARS deployment (20T SWL)
  • Vessel A-Frame system

Benefits

  • SMT-ROV is powerful and versatile
  • Ideal for large-scale debris clearance
  • Capable of relocating 140+ boulders in 24hrs
  • 0.3m to 2.0m boulder relocation capability
  • 30T maximum lift capacity

Our UXO Services

Subsea EOD projects present a considerable challenge, even under the best of circumstances. We thrive under the pressure of operating in these challenging conditions, and we provide clients across the globe with an EOD capability second to none.

Our expanded capabilities include UXO search and identification, disposal and relocation, as well as Free From Explosive (FFE) and As Low As Reasonably (ALARP) Certification Services.

Search and Identification

Using the latest innovative search techniques to find metallic anomalies and then to positively identify whether it is UXO or not. We have the skills, expertise and technology to locate and positively ID no matter what the challenge, whether black water or buried at depth in the seabed.

Disposal

If required disposal can be conducted utilising a range of EOD techniques to remove the site of any explosive hazard, therefore, allowing the project to continue. We have the technology and expertise to offer high-order, low-order or relocation techniques by both diving and ROV.
