HAM 318 Hits Water In Big Way

A mammoth trailing suction hopper dredger, built by IHC Holland NV in cooperation with

Van de Giessen - du Noord, was launched ear- lier this year to rave reviews, and was antici- pated to be delivered and working this month.

The vessel, which joins the company's 16 other trailing suction hopper dredgers, mea- sures 557.7 x 105 ft. (170 x 32 m) and boasts an installed power of 28,500 kW, with a hop- per capacity of 23,000 cu. m. and a maximum dredging depth of 364 ft. (111 m) — all num- bers which easily rank it as the king of the

HAM fleet and make it more powerful and capable by a factor of two.

Rotterdam-based HAM is one of the world's leading dredging companies, but is active in many marine related fields including: con- struction and maintenance of harbor infra- structure and waterways; land reclamation; coastal and embankment protection; offshore services; environmental activities; rock drilling and blasting; and irrigation work.

Novenco Announces Major

Firefighting Breakthrough

Novenco Hi-Pres introduces its new XFlow tech- nology, which it reports offers faster and safer extinguishing of engine room fires. The system utilizes years of proven technology, along with a well-designed mix of very fine water droplets and water mist. "The droplets 'cool' down the fire and extinguish it," said Allan Graff, sales manager for

Novenco Hi-Pres. "The mist encapsulates it and thus 'suffocates' the fire by keeping out the oxygen.

At the same time, the droplets stabilize the mist, making it stay exactly where the problem is. The result is efficiency; a both fast and gentle fire extinction with a maximum of precaution, taken to the machinery and other vital installations."

In addition to fast and efficient fire extinguishing, the system was designed to minimize maintenance and maximize economy. With this in mind, the system was designed as a fairly low pressure sys- tem, making it possible to use standard piping and to keep power consumption low, making it possible to connect to any emergency generator.

Novenco Hi-Pres is a part of the York-Refrigera-

October, 2001 tion group, and is the Group's worldwide supplier of HVAC and firefighting systems for the marine industry.

Smart Pneumatic Level

Sensor with Generic 4-20mA Output

The Bubbler is an electro-pneumatic level trans- mitter that allows remote level measurement using a 4-20mA analog output. The lack of air pressure poses no operational problems, due to an auto- matic one-way valve which closes as soon as the pressure drops below 1 bar, this prevents back flow in the bubbling line towards the transmitter.

Over pressure is also protected against by an automatic one-way valve. • It's the size of a grapefruit • Explosion proof housing • Accuracy .3% full scale • Automatic over-pressure valve • Automatic stop valve for air failure • Automatic cleaning of bubbling line • Connection for pressurized tanks • 2 pair 24 VDC and 4-20mA cable • Top or side mount
