US Flagged Crew Supply Vessel Delivered for BGOS

 

Designed by Incat Crowther and built by Halimar Shipyard in Morgan City, La., the project involved close collaboration between operator, shipyard and designer that originated with the build of a sister vessel, the M/V John Jacob delivered by Halimar to BGOS in 2014.

 

Driving factors in the design and build process included Halimar Shipyard and Incat Crowther providing a modern and fuel-efficient design meeting the latest demands of crew supply vessels in the Gulf of Mexico while preserving the continuity of the existing BGOS fleet.

 

Key features of the M/V Glenn Autry include a vast aft cargo deck of nearly 340 sqm (3,640 square feet) which carries loads up to 450 long tons.

 

The main deck cabin houses 72 passenger seats, a passenger shower and toilet, stores, a dedicated DP equipment room, and access to the upper deck wheelhouse and below deck accommodations. A deck locker, accessed from the cargo deck, is provided for storage of deck cargo securing equipment and other safety gear. The wheelhouse features both forward and aft-facing control stations with sharply designed control consoles.

 

Below deck, the M/V Glenn Autry’s crew members are accommodated in twin cabins, capable of sleeping a total of 12. Adjacent to these cabins is a crew galley and mess area, as well as a large pantry.

 

The vessel’s hull houses a multitude of tanks. In addition to the vessel’s 15,296 gallons of fuel, 17,484 gallons of transferrable fuel can be carried. Additional tanks hold the vessel’s fresh water, grey water, and sewage, while dual-purpose water tanks can also be used to carry up to 42,588 gallons of rig or ballast water.

 

The vessel is powered by a quartet of Cummins QSK 50, EPA Tier III diesel engines, each rated at 1,800bhp. These engines are driven through Twin Disc MGX 6848 gearboxes to four Hamilton HM811 waterjets via cardan shaft assemblies from Driveline Service of Portland. These engines powered the M/V Glenn Autry to a top speed of 35 knots during acceptance trials.

 

The vessel is USCG Subchapter T certified and ABS classed for DP-2 service. Three Thrustmaster 150hp tunnel bow thrusters combine with the four jets and a Beier Radio DP-2 control system to give the vessel superior maneuverability. Electric power is generated from three Cummins QSB7-DM gensets rated at 185 ekW.

 

Additionally, a FiFi-1 firefighting system is installed for the purpose of combating off-ship fires. The system includes two FFS engine-driven pumps, each with 5300 gpm capacity, with integral clutch assemblies and remote controlled monitors.
