BOATS & BARGES

The Florida Department of Natural Resources recently ordered 19 of SeaArk Marine's "transporter" model oil spill recovery vessels.

SeaArk Marine To Supply 19 Oil Spill Recovery Boats

To State Of Florida

SeaArk Marine, Inc., Monticello,

Ark., a leading U.S. supplier of alu- minum workboats for commercial and marine applications, will supply nineteen 23-foot oil spill recovery vessels to the Florida Department of

Natural Resources under a recent contract.

The vessels will be SeaArk Ma- rine's 2308-B "transporter" models, which are constructed of all-welded marine aluminum with a center con- sole, open cockpit and 5-degree semi-Vee bottom hull design. The 23-foot oil spill recovery boats will have a beam of 8 feet, draft of 1 foot 8 inches, freeboard of 1 foot 4 inches, loaded displacement of 7,500 pounds and fuel capacity of 54 gal- lons. The transporter's standard propulsion is a single 100-hp com- mercial OMC outboard motor, but other power options are available.

For responding to an emergency spill, the 23-foot transporter is equipped with portable weir skim- mers and a 400-gallon holding tank.

These trailerable vessels can be quickly transformed for boom and cargo transport by using a lift davit to remove the storage tank and pumping system.

Oil recovery system equipment on board includes a "Skim-Pak" model 18000SH portable skimmer and

Campbell Chain Develops

New Process

To Extend Chain Life

Campbell Chain, a division of

CooperTools, formulated a new gal- vanizing process that reportedly will increase chain life by more than 60 percent.

Used in galvanized Campbell chain, the new cold particle process substitutes for the traditional, diffi- cult-to-control, hot molten metal process, and reportedly produces twice the resistance to corrosion compared to the older method.

In the new cold, mechanical gal- vanizing method, chain tumbles in a slurry of tiny glass beads and zinc particles. The beads "hammer" the model 4000 portable skimmer, "Na- tional Master" peristaltic pump, and 400-gallon aluminum holding tank, as well as discharge and suc- tion hoses.

The skimmers for the Florida De- partment of Natural Resources will be readily adaptable for use as a utility/work boat and designed for easy cleanup including disassembly by a single worker. The vessels will be used at 12 Florida ports.

In the traditional "hot dip" pro- cess, workers immersed chain in a bath of molten zinc, producing a chemical reaction with iron to form a series of zinc-iron intermetallic compounds. But small differences in coating bath composition, tem- perature, and base steel composi- tion can produce significant changes in appearance and coating thick- ness.

Based on extensive testing,

Campbell believes the new mechani- cal galvanizing technique is superior to the hot dip process.
