Subsea Sampling
Subsea Sampling Units
Kraken Subsea offers a comprehensive range of sampling systems, from reliable conventional setups to our groundbreaking SmartASS (Smart Autonomous Subsea Sampling) system.
Designed to eliminate the need for ROVs, divers, or extra vessels, our autonomous units are perfect for dewatering applications, capturing MEG/water samples with precision. With customizable trigger parameters and built-in fail-safes, we deliver seamless, hands-free sample collection tailored to your field’s needs.
Wherever your operations take you, Kraken Subsea ensures your sampling is smart, safe, and efficient.
Features
Autonomous Systems
With a bit of added electrickery, we can provide sampling units that are capable of taking samples autonomously without any intervention from diver or ROV. Simply deploy the unit, install and turn on. The vessel is then free to leave the worksite to perform other operations.
Our autonomous systems are also capable of continuously logging multiple system parameters such as: date, time, pressure, density, temperature of fluid and samples collected/triggered.
Modular Design
Our sampling skids are modular allowing for modifications to be made with relative ease to ensure compliance with our client’s needs.
All our units are rated for up to 250barg operating pressure and 2,000m water depths as standard. This can be increased to 20k psig and up to 4,000m water depth upon request.
A closed system by design, there is no risk of accidental discharge to sea.
Diver & ROV Interface
Our sampling units come in both diver and ROV operable configurations. This gives us added flexibility and our clients peace of mind should there be any changes to vessel availability and selection.
In addition to this, our skids can be adapted with an appropriate interface to seamlessly connect to your system.
Whether you have a specific tie-in fitting or a simple hot stab connection, we can ensure our units are a perfect fit.
Our autonomous sampling skids can be programmed to trigger sample capture based on a number of different parameters such as: time, total volume, density, or a combination of the above. The unit can be reprogrammed at any time using the provided Toughbook with simple to use software to allow for flexibility and versatility during offshore operations.
The autonomous system has been designed to be modular with removable sample cartridges providing up to 10-off samples each. By having a modular system, Kraken can provide as many sample cartridges as necessary to allow for all sampling to be completed without the need to flush and purge the system prior to redeployment – removing this from critical path and streamlining operations.
More Features
Sample Capacity
Our subsea sampling unit has been designed to allow up to 8-off individual samples to be collected within dedicated sample cylinders. Sample cylinder capacity can range from 100ml to 500ml depending on sample size requirements.
All our sample cylinders are certified for transportation directly to a fluid analysis laboratory. Portable, handheld OIW analysers can be supplied separately to support offshore analysis upon request.
Easy to Deploy
Our subsea sampling units have been designed to fit within a standard dive basket and can be deployed in a single lift.
Forklift pockets are incorporated into the basket design to allow for extra manoeuvrability. Required rigging for basket lifting is supplied with the unit as standard. The units have also been configured to optimise space and minimise overall footprint.
Waste Inventory
In addition to the sample cylinders stored within the unit, we can also include larger flushing cylinders.
The purpose of these cylinders is to draw in system inventory prior to collecting samples. This is required in order to clear any tie-in hoses, connection points etc and ensure that all samples collected are therefore representative of what is in the system and aren’t contaminated.
