Chelsea sensors to be fitted to French ferry to progress WaveSentry sea-state forecasting

2012-01-08T09:14:00.000-08:00

Chelsea Technologies sensors to be fitted to French ferry to progress WaveSentry sea-state forecasting project Novel sensors, provided by the Chelsea Technologies Group are to be fitted to a cross-channel ferry to collect vessel motion data as part of the WaveSentry project which is being managed by Marine South East.

This motion data will be processed to derive certain indirect sea-state measurements which will be merged with a range of other data feeds within the WaveSentry sea-state measurement and forecasting system.

Chelsea Technologies Group are specialists in the production of a range of innovative sensors & systems for use in the oceanographic environment.

As part of the WaveSentry project the sensor box, provided by Chelsea Technologies, will be fitted to a Transmanche ferry, the Seven Sisters, which crosses the channel daily. The data collected from the ship will be relayed to the shore and analysed using software from WaveSentry collaborators, QinetiQ to infer the sea state from the ships motion throughout the crossing.

The data collected will be logged against the GPS position of the ship and will be merged with additional data streams by HR Wallingford, to enable much more accurate 'nowcasting' and forecasting of sea state including wave height, period, direction and steepness.

This information should greatly assist the many marine operations (such as shipping companies, offshore oil platforms and renewable energy projects) who are dependent on high quality information on sea-state for both economic and safety decision making. Sea-state information currently available, is based only on atmospheric/ocean models and lacks sufficient temporal and spatial resolution.

The real-time ship data being collected by the Chelsea Technologies sensor on the Transmanche ferry should substantially enhance the data sources available to give more accurate sea-state predictions to multiple end-users.

The sensor box fitted to the Seven Sisters ferry and will collect data for a period of around a year.

WaveSentry was conceived and developed through Marine South East's MEREX Knowledge Network and has secured co-funding from the Technology Strategy Board. The aim of the project is to develop a new information and forecasting tool for managing the risks of marine operations in adverse sea states.

Businesses and organisations can participate in the project through the WaveSentry Knowledge Network which aims to identify and exploit new technological solutions and market opportunities.

Water quality monitors for ship exhaust gas cleaning systems

2011-11-23T07:14:00.000-08:00

What do you think of our new advert? It will be featured in December edition of European Oil and Gas.

Chelsea Tecnologies Group supplies robust water quality sensor systems for monitoring hydrocarbons, turbidity & pH for use in exhaust gas cleaning systems. We have recently supplied Hamworthy Krystallon with sensor systems to monitor their exhaust gas cleaning system as part of the Messina shipbuilding programme.
Each system comprises sensor cabinets monitoring the seawater intake and out-take so comparison data can be used to determine that the cleaning systems operate within acceptable emissions limits. Each cabinet monitors polyaromatic hydrocarbon levels, turbidity, temperature and pH and incorporates a flow switch. Data from the sensors is relayed to a main control system via an Ethernet connection.

Chelsea’s new low cost UviLux hydrocarbon sensor has been re-configured for the specific requirements for both the PAH and turbidity measurements.

The work we are doing with Hamworthy Krystallon expands Chelsea’s existing capability in the supply of in-line monitoring systems to the maritime sector. This is a natural extension to our business supplying FerryBox environmental systems for commercial vessels and ships of opportunity.

For more information or to discuss your particular application, please contact Ellen Keegan, Communications Manager, Chelsea Technologies Group, Tel +44 (0)20 8481 9019 or visit our website.

Detection and early warning of algal growth

2011-09-01T05:57:00.000-07:00

The new Chelsea FASTflow Fast Repetition Rate fluorimeter has been designed to monitor in real-time the ‘health’ of algae and is ideally suited for toxicant detection and bloom prediction. It gives the best indication of the water quality and can give early warning of toxic blooms.

The FASTflow fluorimeter utilises the active chlorophyll a fluorescence from water-borne algae and provides a non-destructive and minimally intrusive method of probing oxygenic photosynthesis. It provides an immediate detection of a wide range of contaminants that attack the photosynthetic process. It is typically used to monitor pre-treated water supplies in pumping stations.

Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is an increasingly common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste.

Data obtained from the FASTflow can address both these issues within the one sensor. By probing the efficiency of photosynthesis of the algae, signals can be obtained that directly relate to growth potential and also provide indications of damage to the algae by contaminants effecting the photosynthetic process. The Fast Repetition Rate fluorimetry (FRRf) technique used allows accurate measurements to be made even whilst the sample is moving past the sensor head. Early warning of algae growth, potentially resulting in a bloom, allows the asset manager to assess options on how to minimise subsequent impact to a processing plant.

Chelsea oil spill sensors for immediate delivery

2011-08-24T06:10:00.000-07:00

Due to the unprecedented demand for its hydrocarbon sensors, Chelsea Technologies has increased production to ensure products are available for immediate delivery.

Chelsea's range of in situ fluorimeters have been used in the offshore industry for many years. Originally developed for military applications the UV AQUAtracka remains unique in its ability to detect very low levels of hydrocarbons to depths of 6000 metres. Many operators are selecting the UV AQUAtracka as the UV fluorimeter of choice for in situ hydrocarbon measurements. The newly released UviLux is designed for shallower depths (600 metres) but maintains high performance levels of detection. Both instruments are capable of detecting crude and refined oils in the marine and freshwater environment and are in use worldwide.

A large batch of instruments was mobilized in response to the Macondo incident in the Gulf of Mexico. One year on they are still in regular use monitoring the dispersion of the oil and the effect it is having on the marine environment.

The recent development at Shell's Gannet Alpha Oil Platform in the North Sea illustrates the importance of having oil spill monitoring equipment ready for use at short notice. Chelsea can mobilize oil spill and pipeline leak detection equipment very quickly with delivery to the incident site within hours.

Water Intake Protection using the new FASTflow FFR Fluorimeter

2011-07-13T04:34:00.000-07:00

Chelsea's Justin Dunning will be presenting on "Water Intake Protection using the Chelsea FAST^flow fluorimeter" during the Managing Risk session at the Sensing in Water 2011 Conference on 21st September.

The FAST^flow fluorimeter is the successor to the successful FAST^trackaII, which had demonstrated detection of a wide range of potential contaminants, and had successfully confirmed its ability to detect contaminated water in the field.

The FAST^trackaII and FAST^flow fluorimeters both operate by utilizing active chlorophyll a fluorescence from water-borne algae (Fast Repetition Rate fluorescence, FRRf), which provides a non-destructive and minimally intrusive method of probing oxygenic photosynthesis. Information from these instruments can provide immediate detection of a wide range of contaminants that attack the photosynthetic process. Of equal relevance is the information gained on the 'health' of the algae present, and its growth potential, which can provide early notification of onset of an algae bloom.

A key benefit of the FRRf technique is its rapidity in taking these readings, which occur in orders of microseconds, which allow robust measurements of photosynthetic ability in flowing water systems.

Justin's presentation will focus on the FAST^flow fluorimeter, which offers three channels of differing wavelengths (as opposed to the single chlorophyll a channel of the FAST^trackaII). The operation of all three channels within the FAST^flow instrument, together with the new FAST^pro 3 software, provides improved estimates of primary productivity. The FAST^flow also provides complete flexibility of control of individual channels allowing interrogation of different algae groups within the sample, i.e. green algae, blue-green algae, diatoms.

Need early warning of algal growth?

2011-07-05T02:28:00.000-07:00

The factors (physical, chemical and climatic) that lead to blue-green algal growth are complex and although most follow a predictable annual cycle, rapid algal growth can happen at any time. Continuous monitoring is key to early detection of harmful algal blooms. Blue-green algae can pose a serious threat to water quality, ecosystem stability, surface drinking water supplies, and public health through toxin production. Chelsea has worked with several water & process control companies to provide sensors for the early detection of algal growth. Our highly sensitive systems can monitor water supplies in real-time either for online applications and in situ measurements. Learn more.

A passion for science and sailing – a great combination

2011-03-18T23:12:00.000-07:00

Imagine if all the sailboats in the world had oceanographic data gathering systems fitted which transmitted data about the oceans they travelled through. In no time we would have an amazing wealth of information about the oceans.

A number of small steps have recently been taken to make this dream a reality. The Yacht Global Ocean Observing System (YachtGOOS) is an initiative designed by MyOcean Resources, with the participation of Environmental Ocean Team, Chelsea Technologies Group and NOC Southampton. The YachtGOOS concept enables oceanographic data to be collected by yachtsmen and women as they sail the oceans.

As a first step, Chelsea Technologies’ MINIpack CTD oceanographic data gathering system was installed on board the Lo Spirito di Stella catamaran. The catamaran is unique in itself, in that it is the first wheelchair accessible catamaran in the world. It has been specially equipted for skipper Andrea Stella who survived being shot by criminals in Miami in 2000. Andrea, who is sailing to defend the rights of the disabled worldwide, set sail from La Spezia, Italy just before Christmas and is now in the middle of the Atlantic enroute to Miami.

During the transatlantic crossing Andrea and his team are taking continuous surface measurements of salinity, temperature and fluorescence using the Chelsea MINIpack oceanographic data gathering system. This data is being fed into the National Oceanographic Centre’s database. Science students and researchers will analyse and interpret the data producing an added value product for improved weather forecasting, satellite data assimilation, marine ecosystem forecasting and coastal and fisheries management.

“The amount of data which can be made available to scientists through the Yacht Global, Ocean Observing System is huge,” said Emilio Tesi, General Director of Ocean Team.
“It is our intention to pilot a second system onboard the Ocean Team boat (Kaitek) which is due to sail around the world for 2 years in September 2011”.

During the transatlantic crossing Andrea and his team are taking continuous surface measurements of salinity, temperature and fluorescence using the MINIpack oceanographic data gathering system kindly loaned to them by Chelsea Technologies.

To find out more about this amazing initiative, please visit us on Stand T8, Ocean Business 2011 (5-7 April 2011, Southampton Oceanography Centre); www.chelsea.co.uk/OceanBusiness2011.htm

Massive step forward for Fast Repetition Rate Fluorometry

2011-03-03T12:12:00.000-08:00

Dr Kevin Oxborough outlined how using
multi-wavelength Fast Repetition Rate fluorometry
can improve the accuracy of primary productivity studies.

Chelsea's Dr Kevin Oxborough gave a talk on Fast Repetition Rate fluorometry (FRRf) at the ASLO meeting in San Juan, Puerto Rico (13th to 18th February), entitled 'Using multi-wavelength Fast Repetition Rate fluorometry (FRRf) to improve the accuracy of primary productivity measurements within diverse natural phytoplankton communities'.

Dr Oxborough's talk included a new method for estimating the number of photosystem II complexes per unit volume from FRRf data (developed with colleagues at NOC, Southampton and the University of Essex). This method represents a massive step forward for FRRf, as it allows for the direct estimation of primary productivity from FRRf data alone. The method currently is being fully integrated within Chelsea Technologies' FAST^pro software, to allow for real time, fully automated estimation of primary production from the FAST^tracka II sensor and FAST^actlaboratory system. Software tools for the analysis of in situ data also are being developed.

The Chelsea team will be demonstrating their new Fast Repetition Rate Fluorimeter system on board RV Callista during Ocean Business (5-7th April 2011) at Southampton Oceanography Centre. Applications for this system now include primary productivity measurements, coastal monitoring, iron fertilization experiments, algal bloom detection and the protection of water supplies against accidental or deliberate contamination.

Chelsea collaborates with Oxford University to a develop single molecule biosensor

2011-02-19T04:16:00.000-08:00

"We are delighted that Sam has chosen to work
with us over the next 3 years on his PhD",
said Dr John Attridge, Technical Director.

Sam Roots, a doctoral student from the SABS IDC programme at Oxford University, will be working with Dr John Attridge at Chelsea Technologies for the next three years as part of his PhD project in fluorescence-based biosensors.

Building on the expertise in the Gene Machines group, led by Dr. Achillefs Kapanidis in Oxford's Biophysics department, and the industrial know-how of Chelsea Technologies, Sam's project aims to build a compact device for single-molecule biosensing and then to develop its novel applications.

Single-molecule biosensing is a very exciting area with potentially wide-reaching effects on the clinical, environmental and food testing markets. Because single-molecule assays can detect analyte molecules one by one, they can have extremely good sensitivity. Combine that with the specificity of some biological molecular interactions, such as the complementary base-pairing of DNA, and you can build very specific, very sensitive testing platforms.

Currently these tests are carried out in Oxford on a large, custom-built platform that requires special training to use and maintain. The purpose of the collaboration between Oxford and Chelsea is to design a compact, user-friendly device of similar capability, initially for the research market.

"Chelsea has a long tradition of working with academic centres of excellence and we strongly support the aims of Oxford University's programme," said Dr John Attridge, Technical Director at Chelsea Technologies. "The collaboration will fuse Oxford University's expertise in single molecule detection techniques with our commercial experience in the development of fluorescence based analytical instrumentation."

Chelsea's UniLux dye tracing fluorimeter used in effluent dispersal study in Darwin Harbour

2011-02-19T04:12:00.000-08:00

50 litres of Rhodamine WT dye were discharged into the
the East Point of Darwin Harbour to determine where
the tide carries waste water pumped into the harbour.

Internationally recognized expert and Charles Darwin University's Professor of Civil Engineering, Eric Valentine is leading a research project tracking the flow of waste from sewerage outlets as part of a modelling study for a new outfall into Darwin Harbour.

The UniLux fluorimeter along with other sensors were attached to an aluminium frame and profiled behind a small diving boat. The boat did transects through the dye plume and measured the concentrations of the dye at a variety of GPS-mapped locations over a number of hours. Real-time information was provided directly from the UniLux to a laptop on the boat.
Ruth Patterson, Research Fellow at Charles Darwin University said, "We were very grateful to Chelsea for supplying the UniLux fluorimeter at such short notice. The data will now be used to validate the hydrodynamic and water quality model and determine better waste water management in Darwin Harbour".

Justin Dunning will be demonstrating Chelsea's range of miniature, multi-wavelength Lux fluorimeters on board RV Callista during Ocean Business. So, if you'd like to see the fluorimeter in action please contact Ellen Keegan to reserve a place.Professor Valentine chose the Chelsea UniLux fluorimeter to conduct Rhodamine WT dye tracing studies in the area. Professor Valentine's team discharged quantities of Rhodamine WT dye and a second tracer, radio-isotope, Technetium 99m into the seawater to determine where the tide carries waste water pumped into the harbour.

Chelsea Provides Unique Sensor Combination for Environmental Monitoring in Gulf Spill

2010-11-06T04:47:00.000-07:00

Chelsea Technologies Group has seen unprecedented demand for its UV AQUAtracka fluorimeter to monitor the extent and dispersion of the oil spill in the Gulf of Mexico. Originally designed for military use these highly sensitive fluorimeters are monitoring the extent of the oil from surface waters to full ocean depth.

The UV AQUAtracka is now being used in combination with the FASTtracka Mark II fast repetition rate fluorimeter to monitor the effects of the oil on the primary productivity of the Gulf. The FASTtracka II has undergone extensive challenge testing to characterise its response to contamination events in the aquatic environment and is providing unique real time data on the response of the marine ecosystem to the elevated hydrocarbon levels in Gulf of Mexico.

Long term monitoring of the offshore and coastal waters of the Gulf is fundamental to understand the rate of recovery of the ecosystem from both the oil spill and the chemical dispersants used. The detection and monitoring of very low levels of hydrocarbons over long periods of time, and their effects on the ecosystem, is key.

"The latest Mark II version of the FASTtracka is fast becoming the instrument of choice for a range of organizations wishing to investigate the physiological responses of a diverse range of phytoplankton within ocean. The ability to combine this with the high precision UV AQUAtracka is provide the investigators in the Gulf with a powerful tool", reports Richard Burt, CTG's Marketing Director. Since the introduction of the FASTtracka II there has been a significant increase in the range of applications from coastal and ocean algal studies to the protection of reservoirs and potable water supplies.

Chelsea has increased production, and is working closely with its suppliers, to meet this increased demand for both UV AQUAtracka and FASTtracka II instruments.

Chelsea announces significant increase in the use of their dye tracing systems by water authorities and environmental consultants.

2010-11-06T03:20:00.000-07:00

“There has been a significant increase in the number of water authorities and environmental consultants who have chosen Chelsea’s dye tracing systems” reports Bruce Kimber, Chelsea’s Customer Services Manager.

“This is mainly due to the system’s reliability, ease of use and low cost. The system is also highly sensitive, robust, and delivers real-time data. It includes a GUI which allows GPS tagged data to be sent via a Bluetooth wireless link to either a PDA or a PC for viewing and storage, thus giving the user freedom in the field to make high precision measurements anywhere, anytime. It can be moored, profiled, towed or affixed to ROV / AUV platforms.”

Typical applications for the dye tracing system include environmental monitoring, pollution control, process control within water treatment plants, commissioning of sewage treatment works and monitoring of pipeline integrity. “The benefit of this system over others” reports Bruce Kimber, “is that it is highly reliable and can be configured to measure a wide range of dyes including rhodamine, fluorescein & other specialist UV tracer dyes.”

Justin Dunning will be on hand on Stand 35a at WWEM 2010, Telford, UK (10/11 November 2010) to answer questions on our dye tracing capabilities.
