LA Fire Dept.

The Los Angeles Fire Department (LAFD) has accepted its new fireboat, L.A. Fireboat 2, which is the largest in the U.S. according to its length of 105 ft. (32 m) and a fire-fighting capacity of more than 10,300 cu. m./hr. It was designed by Robert Allan Ltd, and con- structed in 18 months by Nichols Brothers Boat

Builders.

The basic principle of this ship was developed by

Voith Schiffstechnik, Germany and it is based on the

Voith Water Tractor. During fire fighting the pumps are running with 70 percent of the main engine power and the remaining 30% are sufficient for the vessel to maintain an exact position.

Type OSV

Yard Leevac

Owner Hornbeck Offshore Services

Hornbeck Offshore Services (HOS) took delivery of the HOS Bluewater from Leevac Industries LLC.

Designed by and built for Hornbeck Offshore Services.

LLC, the HOS Bluewater is the company's seventh

DP-2 vessel. HOS Bluewater measures 240 x 54 x 19- ft. The latest of the HOS "New Breed" has been uniquely engineered to offer numerous advantages over existing tonnage. The unique hull form assists in making the Bluewater a very DP capable and fuel-effi- cient vessel. The vessel is certified to both USCG

Subchapter L (OSV) and I (Freight and Industrial

Propulsion and steering control are provided by twin

Voith cycloidal propellers, Model 26 GII/165, provid- ed by Voith Schiffstechnik, each driven by an

MTU/Detroit Diesel Model 12V4000 diesel engine, rated 1,800 bhp (1,343 kW) at 1,800 rpm, which also drive a fire pump through a front end PTO. In addition, a pair of MTU/Detroit Diesel 8V-4000 pump engines each drives two fire pumps. All machinery is resilient- ly mounted for minimization of noise and vibration transmission.

The fire-fighting system delivers a total of 36,000

U.S. gpm at the system operating pressures of approx- imately 10 bar (136,080 lpm or 8,165 cu. m. /hr.) deliv- ered from a total of six pumps to all the monitors. The entire fire-fighting pump and monitor system was pro- vided by Unitor AB (formerly Svenska Skum AB).

The wheelhouse is designed to provide maximum possible all around visibility, with excellent overhead visibility through large visor windows. To keep a clear view, it is outfitted with a Wynn wiping system.
