Bayonne Dry Dock
Reports Strong Year
Bayonne Dry Dock & Repair in Bayonne New Jersey recorded a busy 2005, with business prospects looking good for the coming year as well. According to a com- pany spokesman, the company noted an upswing in
Navy business in 2005, which included the drydocking of the USNS Shughart (T-AKR), a Large, Medium- speed, Roll-on/Roll-off Ships, or LMSR. The 900-ft. ship entered the shipyard in July and was out a month later in August 2005. The main focus of the work included ultra high pressure water blasting and paint- ing, and encompasses mechanical work as well. The company received a second contract for this type of ship, and was expecting the USNS Mendonca (T-AKR 303) to arrive on a 45-day stay on February 12. Work to this ship — which was christened in 1999 at
Avondale in New Orleans — includes modifications to its main engine propulsion exhaust system. In addition to the above work, the shipyard reports vibrant activity in repair and topside work on a variety of commercial ships, barges and tugs

New Machinery Space Fire
Protection
Marioff's offers a new machinery space flooding total fire protection system dubbed HI-FOG MT4. With the system, the company claims there is no need to evacu- ate personnel, seal the space or shut off the ventilation.
By immediate activation, the fire is contained and extinguished in its infancy and the damage can be min- imized. HI-FOG MT4 is touted as an alternative to tra- ditional fire fighting systems and has passed the latest
IMO fire test requirements, as defined in MSC/Circ. 1165, adopted in May 2005.
The key feature of HI-FOG MT4 is that it can be acti- vated the second a fire is detected. The extinguishing media is plain, fresh water in the form of water mist, so an activation will not result in equipment corro- sion. No foam or chemicals are used, so the system does not present any harm to people in the space. The system can be full scale tested regu- larly to ensure that it is always in working condition and to demonstrate its operation to the crew. Finally, there is no need to divert to a port for recharging the system, as the system uses a pump unit rather than compressed gas. The system has been designed to pro- vide both total flooding and local application (IMO
MSC/Circ. 913), using the same pump unit, tubing and spray heads. Using one integrated system saves on component, installation, maintenance as well as train- ing costs. HI-FOG also is an efficient fire extinguish- ment system. It has proven itself in actual ship fires, which typically have been extinguished in about a minute from the moment the fire started.
