OSIL Dredge Monitoring Buoy Network for Van Oord
Ocean Scientific International Limited (OSIL) supplied a network of 1.2m data buoys to offshore construction company Van Oord to monitor turbidity and dissolved oxygen levels in the location of dredging operations. A total of nine data acquisition systems have been produced for Van Oord, and the fully integrated multi-discipline data buoy networks will support dredging operations by providing continuous real-time information about the dredge plume and surrounding environmental conditions.The buoys are equipped with water quality sondes provided from Van Oord’s existing equipment pool, and relay
Improved Sample Preservation via OSIL Multiple Corers
Multiple Corers from Ocean Scientific International Ltd (OSIL) are able to overcome the traditional difficulties associated with benthic sampling and collect undisturbed sediment samples. The multiple corers are landed on the seabed at slow speed which, in combination with the minimal footprint of the corer, prevents a bow wave from forming and driving away the delicate flocculant material that forms on the surface layer of the seabed.Image courtesy OSILThe penetration speed is controlled by a hydrostatically damped piston & central weight system which enables up to 12 core tubes to be slowly
OSIL Releases New Midi Vibrocorer
Ocean Scientific International Limited (OSIL) has launched a new hybrid vibrocoring system, fitting between their traditional Vibrocorer, and their Mini Vibrocorer which was added to their equipment list in the last 12 months.The Midi Vibrocorer is a lightweight coring system that is supported by a traditional deployment frame, making deployments easier in unstable conditions. The Vibrocorer is designed for sampling dense or compacted sediments, and the lightweight nature of the new system enables deployment in off-grid areas or from vessels of opportunity with restricted handling capabilities.The
OSIL Buoy for Dublin City University Project
A multidisciplinary data buoy platform manufactured by Ocean Scientific International Ltd (OSIL) has been installed in Dublin Bay as part of the PREDICT multidisciplinary project. This project will provide a coordinated program of coastal ocean observations that will be used to validate, calibrate and extract as much information as possible from satellite earth observation data as an experimental proof of concept with the aim of generating AI models that can be used to predict environmental change in a range of environments.The 1.9m OSIL Fulmar buoy is recording and transmitting a variety of
OSIL Oil Spill Buoys protecting Desalinisation Plants
Ocean Scientific International Ltd (OSIL) have manufactured a large number of oil spill buoy systems that are now installed in multiple locations to protect the water intake systems of desalinisation plants.If hydrocarbons enter a desalinisation plant’s intakes the filters are rendered ineffective, and it can lead to the closure of the entire plant while the complete filter stack is washed. The lengthy and costly cleaning process also causes additional complications related to the disposal of the wastewater.The OSIL buoys provide an early warning system for the presence of hydrocarbons, providing
Rare East Antarctic Expedition for OSIL Multiple Corer
Ocean Scientific International Ltd (OSIL) reported that its Multiple Corer has recently been employed on the Antarctic Expedition NBP 23-03 which, unusually, had been focussed on biodiversity studies in the East Antarctic.The East Antarctic is a significantly under-studied region (no visits from US vessels in 22 years & very limited contact from other countries), so the results of these studies will be crucial to increasing our understanding of the area. The cruise, which ran from on board the RVIB Nathaniel B. Palmer, focussed on Antarctic Marine Nematodes with the aim of evaluating their biodivers
How AI Can Aid Coastal Water Quality Monitoring
Ocean Scientific International Ltd (OSIL) are investigating improvements to cost effective real-time marine water quality monitoring solutions, using AI modelling to help visualize and predict events.With the aim of improving predictions for high coliform events OSIL have manufactured and deployed a self-contained 1.2m Tern data buoy platform equipped with multiparameter water quality instrumentation, met sensors and GSM data telemetry system. The buoy is monitoring local conditions for a range of parameters including coliforms, providing feedback on sedimentation, low oxygen levels, excess nutrients
OSIL Vibrocorer Plays Role in £600M River Thames Flood Defense Scheme
The OSIL Vibrocorer has been in use on the early works for the River Thames Scheme, a £600 million project to develop two new flood channel sections for the River Thames.The River Thames Scheme aims to reduce the risk of flooding for approximately 15,000 homes and businesses along the River Thames involving a series of measures, including new flood walls and embankments, improvements to existing flood defenses, and flood storage areas and diversion channels to temporarily hold excess water during times of heavy rain.The OSIL vibrocorer has been used to obtain sediment samples in dense or consolida
Deep-Sea ROV Mounted Niskin Arrays Contribute to Sediment Plume Monitoring
Ocean Scientific International Ltd (OSIL) have released a dedicated deep-sea turbidity and water quality monitoring system for remotely operated underwater vehicles (ROV) and subsea vehicles to aid with the accurate modeling of sediment plumes and their wider impact.Certain deep-sea activities such as the collection of polymetallic nodules can generate large sediment plumes that affect the entire marine environment (seabed, water column and marine organisms) over great distances, and The International Seabed Authority (ISA) is shortly due to finalize “The Mining Code”, which will provide a
