In February, Bollinger Shipyards Inc., Lockport, La., delivered the third of four 220-class offshore service vessels the yard is building for New Orleans-based Tidewater Inc.
The Jonathan Rozier, a 207’×53’×19’ OSV, was built to service oil platforms in the Gulf of Mexico and around the world. The steel-hulled vessel, named for Army Lt. Jonathan Rozier who was killed in Iraq last year, was designed by Bollinger for high speed, efficient performance, and large cargo capacity. Tankage includes 127,300 gals. of fuel oil; 131,800 gals. cargo water; 43,800 gals. potable water; 6,000 cu. ft. bulk capacity; and 6,223 bbls. drilling fluid.
The boat’s rig transfer rates are 550 gpm at 295’ for fuel oil and cargo water, 500 gpm at 340’ for potable water, and 700 gpm at 230’ for drilling fluid.
The Jonathan Rozier’s rear cargo deck measures 132’×45’ with a clear deck capacity of 5,808 sq. ft. that can haul up to 1,380 LT of freight.
Twin Caterpillar 3516B diesels, each producing 2,375 hp at 1,600 rpm, provide the vessel’s main propulsion. The Cats are connected to Rolls Royce US 205 Z-drives.
In fair weather conditions, the boat will burn 43 gals. of fuel per hour at eight knots (economical speed), 137 gph at 11 knots (cruising), and 192 gph at 12 knots (maximum).
The Jonathan Rozier is fitted with a hinged and retractable combination bowthruster from Ulstein-Aquamaster (TCNC 73/50-170) for stationkeeping. The bowthruster is powered by a Cat 3508B diesel.
There are accommodations for 26 in 11 cabins. The galley can seat 12 simultaneously. The boat also has a two-bed hospital.
The OSV is ABS Maltese Cross A1-classed, AMS, DPS1, USCG certified Subchapter L, and fully SOLAS certified.
Now that Tidewater has the Jonathan Rozier, Lousteau Tide, and Deville Tide, April’s delivery of the Bourgeois Tide will complete the four-vessel contract.
Another recently completed project at Bollinger was the retrofitting of the 446’, 125,000-bbl. black-oil barge B No. 175 for Bouchard Transportation Co. Inc., Hicksville, N.Y. The yard transformed the barge from a single hull to a double hull in accordance with OPA ’90 regulations. Bollinger put an outer hull on the barge that now measures 468’ and was renamed the B No. 275.
The barge’s stern was notched to accept the bow of the 127-foot tug Capt. Fred Bouchard, creating an articulated tug/barge unit using an Intercon Coupler System.
A keel-cooled Detroit Diesel 8V-71 genset, sparking 75kw of electric power, was installed on the barge as backup for powering the Intercon system’s main generator. The tug and barge were originally built in 1981.
Bollinger also announced a contract to build two 191’×46’×15’ OSVs for L&M Bo-Truc Rental Inc., Golden Meadow, La.
Bollinger is marketing the OSV design as the 180-foot supply boat of today. The design, developed in cooperation with L&M Bo-Truc, features cargo-carrying capabilities of larger vessels without the added equipment, operational, and maintenance costs.
“By comparison, the old 180s carried around 1,750 barrels of liquid mud and 3,500 cubic feet of dry mud. Our new 191 can carry 2,500 barrels of liquid mud and 4,800 cubic feet of dry bulk mud,” said Danny Irby, executive vice president of Bollinger’s new construction. “The older boats usually carried around 500 tons of cargo on approximately 4,000 square feet of aft deck space. Our new boat can carry 900 long tons on her deck that has almost 5,000 square feet of clear deck cargo area.”
Main propulsion for the DP-1 vessels will come from twin Cummins KTA50-M2 diesels, producing 1,600 hp at 1,800 rpm. The mains will connect to nibral propellers through Twin Disc MG-5600 marine gears with 6:1 reduction ratios.
The Cheramie Botruc 38 is scheduled for delivery in June and the Cheramie Botruc 39 will follow in September. —Ken HockeNeuville Boat Works Inc., New Iberia, La., recently delivered the 160’×30’ crewboat Colin B. McCall to McCall Boat Rentals, the crewboat arm of Seacor Marine. (The vessel was named for long-time mechanical engineer Colin Black of Cummins Marine.) The aluminum boat can carry 68 passengers to and from oil platforms in the Gulf of Mexico or elsewhere. The vessel’s rear cargo deck measures 91’6”×24’9” and can carry up to 280 LT of freight. Main propulsion is provided by four Cummins KTA38-M2 diesels, each developing 1,350 hp at 1,950 rpm for a total of 5,400 hp. The Colin B. is also equipped with a Thrustmaster 75-hp electric-over-hydraulic 24” tunnel thruster in the bow. Ship’s service power comes from two 99kw Cummins gensets. There are accommodations for a crew of eight.
VT Halter Marine announced in February that it had signed a $5.2 million contract with Tide Leasing Co. LLC, Birmingham, Ala., for the construction of a stevedoring crane barge. The 200’×75’×14’6” barge will be used by Drummond Ltd. to load coal mined from its South American operations for international delivery. The vessel will be classed by Lloyd’s Registry Class Designation +100AN deck barge and will be foreign flagged. Hydralift AmClyde Inc. will supply and install the crane. VT Halter will install the crane pedestal and the deck winches. The barge and crane will be powered by a 4,000kw diesel-electric plant.
Manitowoc Marine Group’s Marinette Marine has launched the last of 16 Juniper-class cutters for the Coast Guard. The final 225-footer, the Alder, will operate in the Great Lakes and be based in Duluth, Minn. And just as the yard was completing a series of contracts that started back in 1993, it began a new project for the Coast Guard with a keel-laying ceremony for a 240’×60’ icebreaker. Like its predecessor namesake, the Mackinaw, the new icebreaker will also be based in the Great Lakes.
The fourth of a “new breed” of 240’×54’×14’8” OSVs, the HOS Silverstar, was delivered to Hornbeck Offshore Services by Leevac Industries LLC in late January. The SOLAS-certified vessel is powered by two Caterpillar 3516B main engines (each 2,000 hp) and three Cat 3406 generators (each 99kw). The 240 ED-class OSV has a deck area of 7,875 sq.ft. and a deck cargo capacity of 1,725 LT. It also carries 322,014 gals. of rig water, 454,686 gals. rig fuel, and 8,273 bbl. liquid mud. Dry bulk capacity measures 6,240 cu. ft. Accommodations include berths for 16 and seating for 36 offshore workers.
Derecktor Shipyards, Bridgeport, Conn., has completed the first of two 235’ high-speed fast vehicle ferries for the Alaska Marine Highway System. The Fairweather completed sea trials in late February and left in early March for Alaska via the Panama Canal. AMHS hopes to begin service with the nation’s first FVF in May with runs between Juneau and Skagway, Haines and Sitka. The sistership, the Chenaga, will be delivered in 2005. The Fairweather hit a sustained speed of 42 knots at full power during trials. Gary Smith, AMHS’s project director for the FVFs, said the boat rides “beautifully.” —Bruce Buls
