Australia-based Incat Crowther has delivered ‘John Jacob’, a 62.6m aluminium monohull Crew Supply Vessel for US company Barry Graham Oil Service (BGOS).

Built by Halimar Shipyard in Louisiana, Incat says the project’s successful completion if 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.

John Jacob has a vast aft cargo deck of nearly 340m², which carries loads up to 450 long tonnes. 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.

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 water jets via cardan shaft assemblies from Driveline Service of Portland, USA. During sea trials, the vessel reached a top speed in excess of 32 knots.

It’s 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 flexible manoeuvrability.

In addition, the vessel has been equipped with a FiFi-1 firefighting system for combatting off-ship fires, which includes two FFD engine-driven pumps, each with 5,300 gpm capacity, with integral clutch assemblies and remote controlled monitors.
