TECH SPOTLIGHT GALL THOMSON LAUNCHES MOST ADVANCED PETAL VALVE MARINE BREAKAWAY COUPLING IN THE WORLD


Gall Thomson, the world leader in Marine Breakaway Coupling (MBC) technology, has launched an enhanced version of its Petal Valve MBC for the offshore hydrocarbon transfer market.


Petal17 is 20% lighter than the mean average weight of its current range which is already the lightest Petal Valve Marine Breakaway Coupling on the market. The lighter Petal17 delivers improved buoyancy and handling advantages.


The design of the Petal17 MBC builds on nearly four decades of operational experience by Gall Thomson in delivering safe offshore product transfer solutions which reduce risk of damage to capital equipment and spillage, resulting in pollution events. Like others in the range, the Petal17 Marine Breakaway Coupling design has a full and uninterrupted bore, providing zero headloss and zero pressure drop during product transfer.


The robust design features CNC manufactured precision Petals and


improved low pressure metal seals for reliability and reduced risk of leakage on activation. The Petal mechanism has no axles, shafts, hubs or bearings to seize and is totally failsafe. Petal17 fits standard flanges at any recommended location in the hose assembly.


A number of options are also available which include Locking Petals to further reduce the risk of post-activation leakage when low pressure coincides with a harsh environment; and Unit Status Indicators (USI) which allow the operator to conduct quantifiable visual integrity inspections of the MBC upon installation and during service without removing the device from the system. For easier handling during installation and post activation, lifting lugs can also be provided as an option.


Gall Thomson Marine Breakaway Couplings provide an identified safe parting point in marine hose transfer systems and automatically shut off product flow and prevent system damage in the event of an extreme pressure surge or undue significant tensile load on the hose system.


Gall Thomson MBCs therefore minimise risk to assets and damaged reputation and reduces the risk of transfer downtime, injury to personnel, clean-up costs and environmental pollution.


The name Petal17 reflects the evolution of technical designs, material and manufacturing procedures over the decades, based on the advantage of field-verified operational experience.

With a 120 degree field of view (10 degree tilt) and a fast update rate of 30Hz, the Gemini 720is sonar is ideal for poor visibility environments. Gemini 720is features a 720-kHz operating frequency and an integrated sound velocity sensor to assist in providing the sharpest image possible, with accurate ranging. Redesigned for ease of installation onto a variety of ROVs, AUVs and other underwater platforms, the Gemini 720is operates through Ethernet or VDSL communications. Due to the compact size, the Gemini 720is sonar can also be deployed via a pole-mount assembly (customer supplied).


Neil Jackson, Sales and Operations Manager at STR commented on their recent purchase: “As providers of specialist marine equipment and supporters of Tritech products we had no hesitation in purchasing the Gemini 720is to support our customers’


operations worldwide. STR are keen to develop alliances with well-established manufacturers like Tritech and this latest investment will be a welcome addition to our growing inventory of high quality subsea equipment.”
