TECH SPOTLIGHT HUGHES GOES TO EXTREME DEPTHS
Leading UK manufacturer Hughes Pumps, has recently supplied two specially engineered high- pressure pumping systems for sub-sea water jetting maintenance at extreme water depths.
The two pumping systems, mounted on Remotely Operated Vehicles (ROVs), are being used up to 3000m subsea, for a variety of cleaning, cutting and trenching applications, as it is neither possible for divers to work at such depths or practical to run high pressure hoses from the surface to such extreme depths.
The company’s success with this specialist type of application over the last ten years has been due to a clever modification of standard pump materials which provides adequate corrosion protection to prevent seawater from breaching the crankcase oil seals and contaminating the lubricating oil. At 3000m depths the ambient seawater pressure is 300bar (4,350psi), which means the pump requires some clever engineering to protect it.
UK manufacturer Hughes Pumps has more than 45 years experience in the manufacture and supply of High Pressure Water Jetting Equipment for subsea water jetting applications to 3000bar and 375kW (43,500psi & 500hp). The company is one
of the sectors leading suppliers of pumps for seawater pumping at high pressure, for which the pump heads and wetted components that are manufactured in 316 or Duplex stainless steel to provide corrosion resistance.
OCEANWISE AND SEATRONICS SUCCESSFULLY DELIVER TIDE GAUGE AND WATER TEMPERATURE MONITORING NETWORK TO THE UAE
OceanWise working with its Licensed Partner, Seatronics, an Acteon company, are pleased to announce the completion of a three year project to design, install and deliver a fully operational network of 34 water level and temperature monitoring stations for Bayanat LLC in the United Arab Emirates (UAE). The stations are positioned at strategic locations within UAE from the Western Region to the border with Oman, a distance of over 400 km.
Water level is being measured using Valeport VRS-20 Radars with water temperature being measured using PT100 sensors from General Acoustics. All equipment is solar powered and housed in Valeport’s TideStation enclosures. Communication with the stations is being handled using the Smart Telemetry Unit, the ip.buffer, from OceanWise over UAE’s cellular network.

All scientific and system data is being sent to servers located at Bayanat’s offices in UAE.m The servers are running Microsoft SQL Server and OceanWise’s Ocean Database and Port-Log System software. The servers were supplied by Seatronics and installed by OceanWise who also provided system testing and training. The sensors were supplied and installed for the client by Seatronics who are providing ongoing support locally with OceanWise providing remote support from the UK, where required.
This example of collaborative working demonstrates the value of having local knowledge and expertise in the area available to assist the customer in developing its capability and understanding in real-time environmental monitoring and onward sharing of the data across Government departments. The network provides Bayanat with the foundation to include additional monitoring sensors and functionality as the system gains wider use.
Alasdair Murray, Seatronics Regional Manager (UAE) stated that “Our partnership with OceanWise has opened up increased opportunities for Seatronics, and introduced us to new customers in ports, harbours and coastal authorities. The ability to now provide long-term data management services and software support has given us an extra dimension to our traditional business of providing sensors that measure water and weather related parameters.”
