Offshore Annual

ShipConstructor 2004 used for M/V Cheramie BoTruc 38

To meet the requirements of the

BoTruc project. Bollinger's design group chose ShipConstructor2004. the latest version of the 3-D product model- ing software developed by Albacore

Research Ltd (ARL). Canada. Bollinger has been using ShipConstructor for more than six years. For the near future.

Bollinger plans to integrate the

ShipConstructor SQL project database with other related business process data- bases. such as enterprise resource plan- ning. purchasing, and accounting.

Among the design demands of the

BoTruc OSVs is the significant increase of cargo capacity. Bollinger's executive vice president of new construction,

Danny Irby, noted that while the 180-ft 3-D ShipConstructor model of the 191 ft. OSV

Cheramie BoTruc 38 facilitates checking.

Courtesy Bollinger Shipyards Inc., Lockport vessels could carry 1,750 barrels of liq- uid mud and 3,500 cubic feet of dry mud. the new BoTruc 191-ft OSVs will carry 2.500 barrels of liquid mud and 4,800 cubic feet of dry mud. Irby also said that the older boats carried approx- imately 500 tons of cargo on 4,000 square feet of aft deck space, while the new boats will carry 900 long tons on a 5,000 square foot clear deck cargo area.

Additionally, the new OSVs will more than double the fuel oil gallon capacity, at 125.000 gallons, thus giving the new 191-ft OSV more revenue time serving offshore installations and less time returning to base for fuel.

ShipConstructor2004

Bollinger launched the first hull of the two BoTruc OSVs on February 6, 2004.

To fair the OSV hulls, Bollinger chose

ShipCAM, the stand-alone fairing and lofting tool developed by ARL. Eighty percent of the vessels' structural design was then done with ShipConstructor. and 100 percent of the structural part development was created directly out of the ShipConstructor model. Bollinger's design group generated traditional 2-D design drawings for regulatory body and customer submittals directly from the 3-

D model using ShipConstructor's work- shop drawing function. This procedure ensures that all changes to the 3-D model are automatically implemented in all submittal drawings. For pre-fab and panel construction Bollinger utilized

ShipConstructor's automatic 3-D assem- bly drawing generation function. The design group generated profile plots for custom endcuts per assembly and non- assembly profiles, and then used

ShipConstructor's Pipe and Outfit mod- ules to interface the piping and outfitting components into the 3-D model to avoid potential collisions in the field.

ShipConstructor's interference checking function turned out to be a very helpful quality assurance tool for that particular job. This job began with the creation of 2-D orthographic drawings of the piping systems, however after discussions with (Continued on page 41)
