New Software  System Automates Factory Pressure Testing.

April 2012

Pressure testing of large quantities of hoses used in fire suppression on oil platforms has meant our client needed  new  test equipment for his factory that automatically tests, records, and archives data on each new hose.

Fraser Pump has produced a new version of it’s ELAN scada software to run in a windows environment for a new design of pressure test console that meets the needs for rapid testing of hoses and other pressure components.   The ELAN software provides a real time graphical display of test parameters, together with acceptance or rejection criteria to produce a test report on each individual hose.  The software runs on a FiTpc miniature processing module, running Windows 7 together with custom built analogue interface cards.   The console can test up to ten hoses simultaneously.

In addition the console provides steerable remote CCTV coverage of the test bays in high resolution, in order to simplify the inspection task.

In Service Testing of Oil loading Hose Strings.

February 2012

Part of the integrity checking at Oil Terminals is the pressure testing of the whole hose string, whether reeled dockside hoses or floating discharge hoses.  Fraser Pump has recently supplied a West African terminal with a new design of pressure test unit suitable for carrying out  testing of long strings of up to 24 inch diameter hoses.    The unit is designed for rugged offshore use and includes a high volume filling pump, together with a variable speed pressure pump.  The unit has adjustable pressure rise times to meet the different pressure rise and relaxation test specifications of various manufacturer’s hoses.

Oil spill clean up of shoreline contamination.

13th July 2010

Where seaborne heavy oil and tar deposits itself on the shoreline, the cleanup can be very costly and time consuming.

We have carried out tests on the Aquabrade blasting systems for removal and decontamination of thick deposits on harbour walls, dock gates and hulls of ship.   This together with our customer’s feedback indicated that Aquabrade has a role to play at removal of soft sticky coatings.   This is due to the entrained grit combining with the oil under pressure and the wet air stream emulsifying the combination.  The result is a quick cleaning of contaminated surfaces and the residual oil detaching from the surface in clumps, which are then easily collected from the seabed.

Aquabrade is in service with military sub-sea clean-up teams and is being used in the ongoing decontamination of the sunken battleship Ark Royal in Scapa Flow, which, after 70 years on the seabed has started to leak oil, threatening the neighbouring fishing communities.

Subsea Blast Cleaner has Extended Depth

10th February 2009

The Harbour Aquabrade system of subsea grit blasting hasbeen given an extended depth option. Previously specified for operations down to 10 metres underwater for blast cleaning of ship’s hulls,  now, following discussions with clients, an extended version has been produced for operational depths to 25 metres.  This enables operations for cleaning shallow water pipelines, subsea manifolds for SPM and Calm tanker loading buoys.  The system is designed to operate independently at remote sites and operated for up to 90 minutes without reloading water or grit.

Deeper underwater blasting is available from the larger Sub-Aquabrade system allowing working to 60 metres (Sub-Aquabrade SW) and to 120 metres (Sub-Aquabrade DW).

Subsea Grit Blasting for UK’s Ministry of Defence

10th February 2009

Fraser Pump and Engineering are pleased to announce that the UK Ministry of Defence have purchased Harbour Aquabrade for their Marine Salvage Operational Unit.   The Harbour Aquabrade system was chosen following field trials in clearing underwater contamination on steelwork and used by divers from both the Devonport and Greenock dockyards.  The equipment is considered to be suitable for air transport and will be available for immediate deployment worldwide, depending on operational requirements.
