Logging system obtains variety of offshore data
A compact, self-contained data logging system consists of sensors, data logger, batteries, and memory disk.
The system is capable of operating in extreme environments and in water depths of up to 3,000 m.
The basic unit weighs 3 kg and measures 6 cm in diameter and 32 cm in length. Initially developed to measure vortex induced vibration in risers for an oil industry project in the late 1990s, the data logger is modular and suits several measuring devices.
The inclination of drilling risers, particularly in deep water, magnetic direction, strain and load, displacement, pressure, and ocean current velocity are some of the system's measuring abilities.
Fully automatic with eight analog channels and a sampling rate range of 2-30 hz, the system has the ability to provide highly accurate data, the company says.
The system is set as a logging tool that can be retrieved every few months with data being stored and downloaded to a PC for analysis later.

Compact, continuous emissions monitoring system
Here's a complete, continuous emissions monitoring (CEM) system in two compact, field-mountable enclosures that eliminate the need for an environmentally controlled shelter.
The MicroCEM system is designed with a built-in data acquisition and handling system that stores relevant raw and diluent corrected emissions data, status information, calibrations, and alarms for extended periods. The system is housed in two 24 by 20 by 12 in. weather-resistant NEMA 4X rated enclosures that can handle ambient temperatures of -30° to +50° C. The sample conditioning and analysis enclosures can be mounted either together or separately.
MicroCEM will measure oxygen, carbon monoxide, and oxides of nitrogen using paramagnetic, NDIR, and chemiluminescent technologies. These detectors are coupled with Pentium-embedded PC electronics for measurement, communications, and processing capabilities. The system extracts, conditions, and analyzes a sample gas and then processes the emissions data according to US Environmental Protection Agency regulations.

New pump drive head sealing system
The new Moyno Ultra-Guard sealing system is designed to prevent leakage and minimize top drive maintenance by incorporating a hydrodynamic sealing technology. Specifically engineered for downhole pump uses, this patented system is suited for a range of pressures and rotational speeds.
It features two independent seal chambers enclosed in a cartridge. It's simple, compact, and installs easily, requiring no adjustments during operation.
The system utilizes a hydrodynamic principle to provide a seal-to-shaft separation by a lubricant film, which helps reduce friction. The sealing system is also a suitable option for existing wells. It retrofits to most commercially available top drives, the company says.

Extension module aids valve operation safety
The Therma-Safe stem extension module is designed to provide for safe operation of this firm's steam and thermal fluids valves while extending the operating lever beyond typical insulation barriers in piping systems.
The Series E8 module fits directly to all ISO style valve mounting pads, making it modular and easy to retrofit to existing high temperature valves.
The design also features a top pad to provide for actuator mounting in automated systems.

Underwater repair putty
Here's underwater repair putty, a nonrusting, epoxy-based compound that penetrates moisture and forms a strong, permanent seal even underwater.
It is suited for repairing, patching, or rebuilding wet or submerged equipment.
Putty bonds securely to steel, iron, aluminum, brass, bronze, concrete, wood, and selected plastics, the company notes. Easy to mix and apply, it cures at temperatures as low as 40
Because the putty eliminates the need to dry substrates thoroughly before be gin ning repairs, it is suited for emergen cy and routine maintenance tasks in marine facilities and other wet environments.
