Germanischer Lloyd Gains Approval

In time for the effects of the Pressure Equipment Directive (PED) 97/23/EC, Germanischer Lloyd (GL) has been accredited by the Central Authority of the Laender for Safety (ZLS) and approved by the EU Commission as a notified body with the identification number 0098. This new certification allows GL to provide services required by the Pressure Equipment Directive, such as design and type examination, material appraisal, quality system certification, and product inspection and testing. The Directive 97/23/EC governs the placing on the common European market of pressure vessels, steam boilers, piping, and valves and safety devices.

OMEGA Introduces Digital Temperature Transmitters

Omega’s new PRTXB and PRTXAL series are 2-wire transmitters that provide 4 to 20 mA signal representing temperature linearized. This product features a 316 Stainless Steel RTD Probe that capture minimum and maximum readings. Selectable units and an auto shutoff time feature is available for battery powered models (PRTXB and PRTXBL).  Units with alarm outputs are available too. Ideal for Food Processing, Automotive-Engine Testing, HVAC, Lab Use, water bath temperature monitoring

Subsea 7 Completes First Autonomous Inspection Vehicle

Subsea 7, a provider of seabed-to-surface engineering, construction and services, announced that it has completed the design and build of the first commercial AIV, a technology which has the potential to revolutionise Life-of-Field projects.   Subsea 7 has an ambitious plan to develop a series of Autonomous Inspection Vehicles (AIV), initially capable of general visual inspection, through to fully capable work-class sized intervention vehicles

Ocean Works Helps Increase VENUS Ocean Observatory Capability

OceanWorks International has produced the SIIM-375, a mini-Node variant of the Subsea Instrument Interface Module (SIIM) for the VENUS observatory. VENUS, the coastal network of the Ocean Networks Canada (ONC) Observatory, is a cabled undersea laboratory for ocean researchers and explorers. VENUS delivers real time information from seafloor instruments via fibre optic cables to the University of Victoria in British Columbia, Canada

CADC Publish Diver Delta P Guidelines

This guideline by the Canadian Association of Diving Contractors (CADC) provides a basic understanding of the forces and hazards associated with Delta P. The Canadian Association of Diving Contractors (CADC) recently published definitive guidance for divers working in differential pressure (Delta P) environments. Statistics from several occupational health and safety sources indicate that a high number of commercial diving accidents are linked to a lack of proper understanding of the

Making Flare Gas Useful

Wärtsilä has developed the GasReformer, a product which converts associated gas, which is often flared, into usable fuel for its dual-fuel engines.   When producing oil, associated gas is also released from the deposits. In many places this gas is commonly burnt off in gas flares, a waste of energy and a pollutant of the atmosphere. In addition to useful methane, this gas consists of heavier hydrocarbons including ethane, propane and butane

Spence Offers New Line of Safety Valves

Spence Engineering Company, Inc., announced a new line of Safety Valves featuring a soft seat for tighter shutoff in those applications where the operating pressure is close to the set pressure of the valve. These ASME Section I and VIII approved valves also featured rugged construction and two ring control which make them extremely dependable in terms of pop action, seat tightness and blowdown.

Simplan Shaft Seals Selected for Liberty

B+V Industrietechnik have developed the face-seal for water-lubricated sterntubes, for shaft diameters from 60-240mm. Over 40,000 hours of testbed operation, four years of field-testing and the strictest quality control standards have ensured the highest quality, best priced product on the market. The constant shaft-wear and damage caused by stuffing boxes and similar sealing systems, along with high general maintenance requirements have always been a problem

Now the Carousel Ship

Technical proposals for the shipment of natural gas under compression rather than in the refrigerated, liquefied state have surfaced from time to time over the years, but have received a lukewarm response from the marine industry. The considerable cost of the shipboard containment methodology has been a major stumbling block. Now, a Canadian engineering contractor has come up with an altogether more economic solution to the cargo carrying needs of compressed natural gas (CNG)

Marine Pressure Transducer Model: PX2471

The Model PX2471 Marine Pressure Transducer has been designed to meet the stringent requirements of military standard MIL-T-24742(SH) and when invoked ASTM specification F2070-00.  This product is directly interchangeable with other existing pressure transducers designed to MIL-P-24212C(SH) when used with mounting plate assembly A019852. The Model PX2471 marine pressure transducer is a light weight 18 oz (510 gm) transducer, available in pressure ranges from 15 to 10,000 psi
