Texas Shipbuilding

Gets Big Drilling

Barge Contract

Texas Shipbuilding Company,

Houston, has been awarded a con- tract by Atlantic Pacific Marine

Corporation for construction of two inland, posted drilling barges.

The drilling barges will have a rated drilling depth of 20,000 feet with a maximum water depth of 20 feet. Delivery of the first unit will be in the first quarter of 1981, and delivery of the second unit will be July 1981.

Texas Shipbuilding's yard is located near Jacintoport on the

Houston Ship Channel. The facil- ity, acquired by the present own- ers in 1979, has the capability for marine repairs and construction of jackup drilling units and drill- ing barges, service vessels, tugs, and oil and deck barges.

Literature Available On

Bomar Deck Hatches

A new brochure describing the company's line of flush deck hatches is available from Bomar,

Inc. These hatches feature a heavy cast aluminum top with reinforc- ing ribs and a y^-inch-thick base ring. Deck openings of 20-inch di- ameter and 15 by 24-inch are available, and inside or outside opening is standard.

All cast-aluminum parts are made of high-strength, highly corrosion-resistant Almag-35; all hardware is stainless steel.

The Bomar design prevents any metal-to-metal contact between top and base when closed. Parts are isolated by a neoprene gasket and nylon friction pads. This pre- vents freeze-up in highly corro- sive environments. The hatch cov- er is also available with a mild steel base for welding to steel decks.

These hatches have been used on passenger-carrying vessels, and are approved by the U.S. Coast

Guard for emergency escape pur- poses.

C. Zurich, product manager, Bo- mar, Inc., P.O. Box 314, Charles- town, N.H. 03603.

Joint Venture Formed By

Taylor And Hydrospace

Taylor Diving & Salvage Com- pany, Inc. Belle Chasse, La., has entered into a joint venture with a Newfoundland-based diving company to establish the firm of

Hydrospace Marine Services.

Taylor Diving president Ken

Wallace joined with Bill Lukeman and Max Ruelokke, partners in

Hydrospace Engineering of St.

Johns, in announcing formation of the new company, which is geared 28 to provide a complete range of diving services for the rapidly expanding offshore industry in

Canada's Maritime Provinces.

Hydrospace Engineering, the

Canadian joint venture partner, has been a major factor in ma- rine engineering and diving in

Newfoundland/Labrador since 1974, while Taylor's position as a leader in diving technology and techniques is well-known to com- panies and contractors worldwide.

At present, Taylor is providing training for Hydrospace divers at its headquarters in Belle Chasse and various offshore locations. In addition, the joint venture will have access to Taylor's large in- ventory of saturation diving, RCV, and hyperbaric welding equip- ment.

In a joint statement, Messrs.

Lukeman, Ruelokke, and Wallace said: "By drawing on the strengths and resources of the joint venture partners, Hydro- space can successfully complete projects of varying magnitude and complexity."

On the oceans of the world, we are most noted for our heavy-duty 3 and 10-cm radar systems.

More than 50.000 vessels have been fitted. While less visible, other

Raytheon products are even more numerous.

These include: • RAYCAS, the finest and most economical

Collision Avoidance

System yet devised. • VHF-FM and SSB

Radiotelephones. • Fathometer® Echosounders. • Doppler Speed Logs. • SATNAV and Loran-C. • Facsimile Receivers.

All sold and serviced in major ports everywhere.

DOPPLER LOGS

Doppler logs give accurate speeds and simultaneous bottom soundings.

Single or dual-axis.

There are three models of the famous

Raytheon

Doppler Log:

DSN-250 for continuous fore/ aft speeds;

DSN-350 which can be switched to show either fore/aft or port/starboard speeds: and DSN-450 which shows speeds in both axes simultaneously.

All three are proven performers with these unique features: • "Normal" mode readings up to 40 knots within 1/10 knot. • "Mooring" mode readings accurate within 1/100 knot. • True speeds shown over bottoms as deep as 1000 feet. • Selectable "water-mass" mode for relative speeds through water. • Simultaneous bottom soundings to 1000 feet with adjustable minimum depth alarm. • Automatic water temperature and salinity compensation. • Self-testing. No calibration. • Large, easy-to-read LED display with mechanical "distance-run" counter. • Optional digital and analog "dial" remote displays. • Single transducer.

Satellite Navigator gives worldwide fixes accurate within 100 yards every 30 to 90 minutes.

The "complete navigator", Raytheon

JLE-3400 acquires and displays very accurate Lat/Long fixes derived from navy navigation satellites in polar orbit.

Between satellite fixes, computer- generated dead-reckoning fixes are shown. Dead-reckoning data is keyboard entered or automatically supplied by a gyro compass and dual-axis doppler log.'

Featuring a large 9-inch CRT, the JLE-3400 will also display such important data as: • Date and GMT. • Time since last satellite fix. • Time and angle of next satellite fix. • Ship's speed and course. • Data from up to ten way-points including: course-to-steer for

Rhumb or Great Circle tracks, distance run, ETA's etc.

A printer for displayed data and a remote CRT display are available as options.
