Surge in Snow Catcher Demand

Global interest in Marine Snow Catchers for carbon and nutrient cycle studies has been steadily increasing in recent years, but Ocean Scientific International Ltd are reporting that the level of sales has seen a sharp increase over the past few months.

The Marine Snow Catchers are large volume water samplers which possess separable top and bottom sections. These modular sections allow researchers to collect and characterise suspended and sinking particles in the water column, as the samplers are allowed sufficient time on deck following recovery to permit sinking particles and aggregates to collect in the bottom chamber before the overlying water is drawn off from the top portion. The bottom section can then be removed separately for recovery, study and analysis of the accumulated samples, which is aided by the flat-bottomed design of the chamber.

These samplers can facilitate a greater understanding of the export processes of the oceanic organic carbon and nutrient cycles, and can help to predict how these processes may change in the future. The Snow Catchers can also provide an insight into the extent of oceanic microplastic in the water column, as the internal design of the sampler reduces turbulence and eliminates issues with pressure waves associated with towed net systems which can result in over/under reporting of concentrations.

The Marine Snow Catchers are currently available in three sizes; 50L, 100L or 300L.

OSIL Giant Piston Corer for CSIRO

The Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia have purchased a 24m Giant Piston Corer system for the RV Investigator from global marine sediment coring experts Ocean Scientific International Ltd (OSIL).

The modular deep sea sediment coring system comprises four 6m-long barrels, a stainless steel head with removable lead weights and a mechanical trigger arm with 1m long pilot core. The system has been specified with deck stands, deck storage for the head and barrels and a comprehensive package of tools and spares.

The OSIL Giant Piston Corer systems can achieve recovery rates of over 95% in soft sediments and provides a more complete, longer and less disturbed sample than traditional gravity coring systems owing to the unique integral piston, which reduces internal friction and prevents plugging.

 Piston Corers are one of the most important basic tools used in the study of marine sediments, and OSIL offers customisable systems (including Launch and Recovery Systems and Winches) from 4m to 60m in length. Ocean Scientific International Ltd. have a vast wealth of knowledge and experience in designing, planning and installing customised coring systems, and can pair the system with a variety of different handling systems to suit the existing vessel layout, equipment and available deck space.

OSIL are experts in the manufacture, global supply and operation of sediment corers up to full ocean depth, with particular experience in the oil and gas and marine mining industries and a worldwide customer base that covers a wide range of sectors including offshore renewable energy, coastal engineering, ports and harbours, oil and gas, aquaculture, water and utilities, academia, research and statutory monitoring.

Modified Multiple Corers

The Multiple Corer is universally acknowledged as being the only way of reliably collecting a truly undisturbed sediment sample from the seabed with its ability to consistently collect up to 12 high quality samples simultaneously, including the sediment-water interface and benthic fauna, meaning it is the primary corer for environmental impact assessment worldwide. The sample preservation is achieved through hydrostatically damping to control the speed of descent of the core tubes into the sediment.

 

 

 

 

 

 

 

Variations to the standard multiple corer design are available from Ocean Scientific International Ltd. to accommodate customer requests for longer sample lengths, and to allow for more compact transportation constraints. OSIL can extend the corer frame to offer an increased sample tube length from the standard 600mm, (most recently for a sample tube length of 1200mm to provide a sediment sample 1000mm long and 200mm of overlying supernatant water), and the corers can easily be fitted with core tubes of varying diameters by swapping out the mounting assembly. The frame of the corer can also be split in two to facilitate shipments where height restrictions are a known issue.

 

 

 

 

 

 

 

The system is constructed from stainless steel and features detachable core assemblies, which enables the core tubes (or if necessary the entire core tube assembly) to be removed from the corer for analysis or storage. The core tubes are sealed top and bottom once the sample has been taken, allowing rapid retrieval of the corer without jeopardizing sample integrity. Delivery times for the corers and spares are low, meaning last minute cruises can be catered for and systems can be kept in constant use for many years.

 

 

 

 

 

OSIL have an abundance of global experience in the construction and operation of a wide range of sediment coring equipment, including the industry standard Multi Corer and the unique Giant Piston Corer which is capable of achieving cores up to 60m in length.  OSIL also offer a full design, build and implementation service for all of their heavy offshore equipment.

Complete Oil Spill Monitoring solutions for vulnerable areas

Global environmental monitoring experts Ocean Scientific International Ltd (OSIL) produce oil spill monitoring solutions for remote areas for both aquatic and terrestrial applications where there is a concern over the potential for exposure to hydrocarbons.

OSIL build and install systems including oil spill monitoring buoys that are capable of detecting and monitoring surface sheens, oil in water monitoring buoys that can identify and quantify crude oil and refined fuels present in the water column using submersible sensors, and land-based non-contact oil spill detection systems. These structures can detect a variety of hydrocarbon based substances, and can be set up to ignore other materials that fluoresce in the same wavelength.

Real time data from these monitoring systems can be transmitted via GSM, UHF radio and satellite to a base station and can be displayed online using the OSIL data to web service, or can be integrated into the clients own computer systems, providing users with a variety of alarm options including email and text alerts, audible alarms or visual indicators such as flashing lights.  The systems can also be equipped with additional sensors depending on customer requirements.

The Oil Spill monitoring buoys and land-based systems utilise a real time non-contact hydrocarbon sensor, which is equipped with a pulsed UV LED beam and optical photo-detector with on-board software to enable detection of oil spills autonomously and immediately alert the users to any changes to protect vulnerable areas day and night, even under harsh weather conditions.

The Oil in Water buoy systems are equipped with submersible hydrocarbon sensors that can be positioned anywhere in the water column using the mooring systems themselves.

The systems are available for a variety of platforms, with OSIL engineers providing customers with an installation service complete with full training in the operation and maintenance of the equipment and on-going system support.

Box Corer T-Bar System now available from OSIL

A sophisticated T-bar mini-penetrometer for exclusive in-field seabed strength profiling of box core samples is now available from globally renowned environmental monitoring experts Ocean Scientific International Ltd (OSIL).

 

 

 

 

 

 

The T-bar penetrometer measures the resistance of sediment to continuous penetration at a slow steady rate using a cylindrical rod (T-bar) at the end of a perpendicular push rod or thruster and, uniquely, is small enough to fit on to the top of a box corer sample box immediately on its recovery on-deck to allow for on-site sampling on the back of the vessel.

 

Using axial load, dual axis tilt and friction sleeve sensors the system can provide a real time display that records penetration length, penetration resistance and inclination from the vertical for every millimetre of penetration at 2cm/s, and also stores the data for later analysis. The system can be fitted with a 25cm2 T-bar, 50cm2 T-bar, or 50cm2 Ball, depending on soil conditions.

 

Penetrometer testing is used to characterise the undrained shear strength and residual shear strength profiles of seabed soils, which provides valuable data for the positioning and design of a variety of subsea structures.

Another success for OSIL Giant Piston Corers

OSIL have successfully completed sea acceptance tests aboard the MV Xue Long 2 on an OSIL 22m Giant Piston Corer system in the South China Sea, proving the system with excellent sample recovery rates and ease of handling.  The system was installed and operated over a 10 day period with 2 OSIL engineers on board to provide training to local scientists.

 

The 22m system is installed into and deployed using a MacGregor Triplex handling system.  The corer was successfully deployed in deep water collecting over 85% sample recovery on its first deployment.  With further system tuning scientists are looking towards 95% plus recovery rates which are possible using the OSIL corer.  The unique piston design provides a more complete, longer and less disturbed sample than traditional gravity coring systems.

 

The Giant Piston Corer will be used by the Polar Research Institute of China (PRIC) for marine sediment studies.  The system is modular and easily assembled for rapid deployment in all conditions.  Due to its modular nature systems up to 60m in length are available from OSIL for use in soft sediments.
