Products

At Kappa Offshore Solutions, we combine deep marine seismic engineering expertise with hands-on field operations experience gained across more than 200 projects in over 30 countries since 2012.

This unique dual perspective — designing on the drawing board and proving performance at sea — enables us to create equipment that truly works: reliable, robust, and perfectly adapted to the toughest offshore conditions. Our products eliminate common pain points, reduce mobilization time, simplify operations, and deliver superior data quality from day one.

KappaSpark delivers cleaner, higher-quality broadband seismic data with unmatched reliability in demanding marine conditions. Engineered from real offshore experience, this innovative ghost-free sparker platform combines exceptional hydrodynamic stability with precise depth control and centimetric GNSS positioning, ensuring consistent performance even in varying sea states.

Compact, lightweight (~130 kg), and requiring modest power, KappaSpark mobilizes quickly on vessels of opportunity, integrates seamlessly with commercial sparkers like the SIG PULSE (700–2000 J), and minimizes downtime, mobilization costs, and operational risks—all while maximizing survey productivity and data quality from the first line.

 

KappaHub

The Turnkey Containerized Distribution System.

KappaHub

KappaHub transforms deck operations by delivering immediate, reliable hydraulic and electrical power to up to eight pieces of equipment—winches, tools, or any consumer—with just a single 400 V connection. Housed in a standard 20″ ISO container, this all-in-one solution eliminates the hassle of on-site sourcing, custom rigging, and complex setup, allowing your team to mobilize faster and start productive work from day one.

Its robust double hydraulic power unit, featuring two 37 kW air-cooled motors, load-sensing piston pumps, 200 bar pressure, and a 600-liter tank with eight precise PVG32 proportional outputs, operates independently without external cooling or ventilation. Pre-terminated main power cables (up to 31 m) and a full set of high-pressure hydraulic hoses ensure secure, plug-and-play connections, while practical interior features—a workbench with tool organizer, storage cabinet, internal fire detector, and oil retention tray—support safe, efficient daily use even in harsh offshore conditions.

Compact and portable at just 2,250 kg gross weight yet capable of handling 28,000 kg loads, KappaHub deploys seamlessly on any vessel or site. It reduces logistical complexity, cuts mobilization costs, minimizes downtime, and guarantees dependable power and fluid transfer, making it the confident choice for demanding marine projects.

We are here to help.
