Seismic ocean bottom node acquisition without ROV

Allton has developed an innovative Drop & Pop vehicle solution for cost-effective seismic node acquisition which enables the deployment and recovery of seismic ocean bottom node (OBN) without the use of remotely operated underwater vehicles (ROV)

Guided by industry demand for improved efficiency and reduced costs for the acquisition of sparse node grid seismic and 2D transects, Allton was led to research and develop an innovative solution – a seismic OBN Drop & Pop vehicle.

The tool, which does not require the use of ROV, can be deployed at a speed of 5 knots and also be utilised with other environmental measurement tools designed for use on the sea poor, such as water temperature, pH and salinity.

The Drop & Pop unit can host any standard seismic OBN available on the market. The system was designed to be modular and containerised for logistical efficiency and easily fits on a standard back deck on a vessel of opportunity.

As one of Allton’s cutting-edge Multiphysics Solutions, the Drop & Pop vehicle’s mechanisms are based on the same laws of physics and similar technology to that used to build its Multiphysics Nodes (EM + Seismic OBN). Patents to protect the intellectual property were filed in early 2024.
