SoftwareBackground
Kappa Offshore Solutions has delivered business intelligence services to major actors of the seismic industry since 2013.
Our company first proposed the concept of vessel safe towing capacity, defined as the maximum number of streamers a specific vessel can tow safely for a given seismic configuration (streamer length and separation).
KEOS
The survey cost optimization software
KEOSWe first proposed this concept and defined it as the maximum number of streamers a specific vessel can tow safely for a given seismic configuration.
We designed proprietary algorithms to assess the safe capacity for each seismic vessel, based on the vessel’s deck arrangement and the propulsion plan capabilities versus hydrodynamics forces induced by the seismic towed equipment.
We developed a thorough vessel and seismic configuration cost model: this gives Keos users access to overall survey cost estimations with unmatched accuracy.
We also computed a variety of key performance indicators such as cost per square kilometer of 3D seismic data or total CO2 emissions.
Keos relies on a unique proprietary database developped by Kappa Offshore, which encompasses the main technical and economic characteristics for each vessel of the global 3D seismic fleet. It includes the precise hydrodynamic properties of an extensive library of different seismic towing configurations.
