Site clearance
Overview
Boulders and debris can pose a significant challenge for developers, potentially leading to extensive layout alterations and rerouting; adding considerable time and expense. Our industry-leading techniques offer a highly efficient solution to the challenge of boulder relocation and debris clearance on site. 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.

Subsea multi-tool (SMT) ROV
The SMT ROV offers a highly versatile and cost-effective solution to the challenge of boulder relocation and debris removal. Its modular design supports 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.
With the ability to accommodate various inspection and survey sensors simultaneously, including the PanGeo SBI, the SMT-ROV can perform post-removal confirmation surveys to potentially remove the need for a survey vessel mobilisation.
System deployment
The system can be deployed using one of three methods:
- Vessel AHC crane deployment with tagging tower (30t can be accommodated)
- Dedicated A-Frame LARS deployment (15t SWL)
- When deployed through the moonpool, increased operational wave limits for launch and recovery are achieved.
UXO clearance services
We are the market leaders in providing UXO Identification and disposal services and have been involved in these operations since 2009.
Our expanded capabilities include UXO search and identification, UXO disposal and relocation, as well as Free From Explosive (FFE) and As Low As Reasonably Practicable (ALARP) Certification Services.
