American shipbuilders rarely deliver a ship that’s built for heavy duty offshore rig supply work that also turns heads, but a recent delivery from Houma, Louisiana-based New Generation Shipbuilding is already doing just that with the new 171-ft ‘Mr. Ernie’.

This striking vessel was built for same-name owner Ernie Vicknair and his partner Joe Gregory for rig support work in the Gulf of Mexico.  According to Cummins Hotips, credit for the distinctive super-structure design goes to Incat-Crowther, although the design and engineering support team also included Parfait Maritime; Mino Marine LLC; and Farrell & Norton Naval Architects. The outcome of their collective effort contradicts the old saw that if you want to kill any idea in the world set a committee to work on it.

Propulsion power
A pair of Cummins K38M Tier 2 diesels deliver a total of 2000 HP through Twin Disc MGX-5321 gears to 72x65-inch Bird Johnson 4-blade propellers to give the vessel a respectable and economical 13-Knot service speed.

Cummins explain that this engine is an upgrade of their rugged KTA38-M0 turbo-charged and after-cooled engine to fill a much needed gap in the market for durable, reliable power designed for use in areas covered under U.S. EPA Tier 2 and EU Stage IIIA emissions regulations. The 38 liter, V-12 K38-M Tier 2 has the same footprint, mount, ratings and optional equipment similar as the previous engine and thus installation is simplified.

Emissions compliance is achieved by minor modifications in air handling and fueling, adjustments to timing and the addition of low temperature after-cooling. The engine also features the proven simple mechanical Cummins PT fuel system enhanced by CENTRY electronic governing, making it one of the few high horsepower Tier 2 certified engines with a mechanically controlled fuel system.

Cummins also supplied a 350 HP QSM11 engine to power the Bruvoil bow thruster (DP1 class vessel) and a pair of ABS-rated QSM11 powered 300 kW gensets meet electrical needs.

General layout
The raised focsle deck extends well forward and right to the side-shell allows for roomy accommodations with bunks and mess room for 32 people. This provides a variety of 6, 4 and 2-person cabins for the four crew-members and 28 other workers. At the same time, the aft deck provides an impressive 112 by 30 feet of clear cargo space with a 375 LT capacity.

Below deck there is extensive tankage including dual-purpose tanks for fuel or liquid mud.. In addition to a dedicated 13,460 US-gallon potable water tank, there is also a 92,328-gallon ballast or potable water tank. This will give the supply vessel great flexibility with a total deadweight of 707 LT.
