JBS Fabrication Ltd subsea excavation services provide controlled flow excavation (CFE) subsea excavators and auxiliary equipment using our patented Sea Axe. The equipment is available for lease and sale complete with a full complement of experienced operational personnel available 24 / 7 to support Sea Axe operations globally.
Sea Axe CFE equipment is the best available technology for subsea and pipeline excavation in the oil & gas, renewable energy and decommissioning sectors.
Sea Axe subsea trenching capabilities have evolved from the traditional mass flow excavation subsea technology. Sea Axe is set to lead the market in subsea controlled flow excavation.
The Sea Axe excavator is easily adaptable and can excavate a wide range of seabed materials up to 200kPa shear strength using the in-built auxiliary jets.
Sea Axe will meet specific project requirements such as rock, sedimentary displacement or seabed preparation.
Sea Axe can remain in the water for up to 72 hours and requires minimal maintenance.
Sea Axe is a non-contact and non-intrusive mass flow excavator, making it ideal for offshore windfarm subsea cable work or reducing stress on live cables via high-spot subsea excavation.
