Operational recommendations

Access our recommendations for best practice node operational management

Please take the time to read our recommended procedures for correct operation of STRYDE seismic systems, listed below.

Your STRYDE field support representative will review these with you before your project, but it is important to take note of these key points before purchasing or leasing STRYDE's seismic equipment.

Nimble System™ siting

You must provide a clean, dry, climate-controlled environment for siting STRYDE’s Nimble Seismic System™ . The site must be provided with an adequate power supply for the System Case and the number of Nest Cases that you are operating (see below). A reliable internet connection must be provided if you require STRYDE to provide remote field support.

Nimble System™ power requirements

The System Case UPS is rated at 2.7kW and can be connected to a circuit protected by a breaker with a minimum rating of

  • 16A (230V input, APC SRT3000XLI)
  • 30A (120V input APC SRT3000XLA)

Make sure you do not exceed the current rating of this breaker e.g. by connecting Nest Cases to the same circuit.

Each Nest Case is rated at 1kW and

  • draws ~5A (230V input)
  • draws ~9A (120V input)

You should ensure that the number of Nest Cases connected to each circuit does not exceed that circuit’s current rating. For example, if your circuit is rated at 16A and 230V input, then up to 3 Nest Cases could be connected.

Unpacking & packing

You should retain all packing materials supplied with the STRYDE system and keep them in dry storage so that they can be reused upon project completion to reduce the chance of equipment being damaged during de-mobilisation.

Node charging

Node batteries will typically be fully depleted when you receive them from STRYDE. It takes 4 hours to charge the battery of a fully-depleted node. You must ensure that adequate time and personnel are allocated at project start-up to allow all nodes to be charged in a timely manner.

STRYDE hardware has built in safety measures to prevent overheating, however systems should not be left unattended during charging and harvesting operations due to the potential risks of events such as a sudden air conditioning failure.

Node storage

Nodes should be stored in a safe location where the risk of physical damage is minimised.

During operations in hot environments, nodes should be stored so their temperature does not exceed 45°C (e.g. avoid direct sunlight).

Node transportation in the field

Nodes should be kept in Magazines during transportation around the project area (e.g. in the back of pick-up trucks), and Magazines should be secured during transportation (e.g. using ratchet straps).

Node planting

Nodes should be planted upright (i.e., with the clear cap pointing upwards) at a maximum angle of 15° from vertical.

In dry environments, it is recommended that Nodes are shallowly buried to optimize coupling and minimize noise.

Where ground conditions are wet, it is recommended that Nodes be planted to the base of the Rope attachment eyelet, to ensure optimum GNSS performance. Complete burial of Nodes in wet ground is not recommended as this may prevent Nodes from acquiring GNSS time-fixes.

Your STRYDE field support representative will be able to discuss options for deployment tools and techniques depending on the specifics of your project.

Node cleaning

STRYDE Nodes™ must be cleaned and dried before loading into Nests for charging and harvesting to prevent ingress of dust, dirt and moisture into the Nest electronics.

  • For our Nimble system, the most common approach is to clean and dry the nodes manually (e.g. using a pressure washer and compressor) when they return from the line
  • For our Pro and Compact systems, we recommend using STRYDE’s dedicated cleaning container

Nas3

Physical media for seismic deliverables

The STRYDE system supports writing of deliverables (gathers and optional continuous records) to NAS drives. You must ensure that enough NAS drives are available on the crew at project start-up to handle the volume of deliverables that your project will generate.

Your STRYDE field support representative can help you estimate the output data volumes for your upcoming survey, and NAS drives may be purchased from STRYDE if required.
