205' Monohull Crew Supply Vessel Delivered
Incat Crowther is pleased to announce the delivery of John Jacob, a 205’ aluminum monohull Crew Supply Vessel, for Barry Graham Oil Service (BGOS) of Bayou La Batre, Alabama. Built to a high standard by Halimar Shipyard in Morgan City, Louisiana, the project’s successful completion is the result of a close collaboration between operator, shipyard, and designer.
Driving factors in the design and build process included providing a modern and fuel-efficient design meeting the latest demands of crew supply vessels in the Gulf of Mexico, whilst maintaining continuity with existing BGOS fleet operational features. The teamwork between Incat Crowther and Halimar during the design and build process was instrumental in ensuring that John Jacob meets and exceeds BGOS expectations.
John Jacob has 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, passenger shower and toilet, stores, a dedicated DP equipment room, and access to the upper deck wheelhouse below deck accommodations. A deck locker, accessed from the cargo deck, is provided for storage of deck cargo securing equipment and other safety gear. Upstairs, the wheelhouse features both forward and aft-facing control stations and smartly designed control consoles.
Below decks, John Jacob’s crew members are accommodated in twin cabins, capable of sleeping a total of 12. Adjacent to these 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. Further 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 water or ballast.
The vessel is powered by a quartet of Cummins QSK 50 engines, rated at 1,800bhp each. These drive through Twin Disc MGX 6848 gearboxes to four Hamilton HM811 waterjets via cardan shaft assemblies from Driveline Service of Portland. The vessel reached a top speed in excess of 32 knots during sea trials.
The vessel is USCG Subchapter T approved 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 6CTA 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,
