Lapp Assists with Polar Region Marine Project

SAMS Research Services Ltd (SRSL) provides marine consultancy services, supported by innovative science and research. Environmental Impact Assessment (EIA) services are one of the principal areas of business for SRSL.

EIAs evaluate the probable environmental impacts of future developments and projects by researchers. The ‘SIMBA Project’ is a development which SAMS have been engaged with recently.

SIMBA (Sea Ice Balance Buoys) are units which comprise of a platform and sensor which monitors temperatures in snow and water. SIMBA are able to find material interfaces, for example, ice and ocean boundaries, and are able to monitor the thickness of snow and ice.

The SIMBA unit being used

The apparatus is easy to deploy, compact and inexpensive. SIMBA units also come equipped with an in-built GPS which tracks the movement of sea-ice, a barometer, magnetometer and an external sensor for air temperature readings.

SIMBA units offer a reliable means for constant monitoring of ice thickness in the Polar Regions, and provide time development across annual rotations.

The data gathered from SIMBA units is suitable for process model evaluation, weather forecasting in Polar Regions and the monitoring of sea-ice thickness for shipping and transport purposes.

Lapp Group UK was asked to consult on the potential improvements to the existing SIMBA design. In particular, they focused on how the units electrically connected to the stationary probes.

The customer targeted specific improvements to the flexibility and reliability of the cable being used, especially at low temperatures (-35°) and damp environments. Additionally, the cable integrity during exposure to UV rays was targeted for improvement.

Working alongside the customer to recognise the correct components required for the improvement criteria, Lapp offered samples for assessment within their state of the art lab conditions.

After extensive testing, the OLFLEX® ROBUST 215C and EPIC® HA housings with the EPIC® STA-6 insert were selected as the final prototype.

The final requirement, minimising damage by UV rays was achieved by adding a white heat shrink to the exposed OLFLEX® ROBUST 215C. This allowed for a fast and reliable ‘plug and play’ system once fixed in place and on the pole.

Due to the success of the improvements made by Lapp, we are now continuing to work with SRSL on a second generation solution for extended data monitoring.

The OLFLEX® ROBUST 215C is an all-weather control cable which has been extensively screened to a wide range of chemical media. This cable is flexible in extreme conditions, down to -40°. The 215C is resistant to contact with oils, greases and waxes, with good resistance to bio-gases and ammonia.
