IBOM--SPM Service Vessel for Nigeria

Horizon delivers SPM vessel for Nigeria
Horizon Shipbuilding, Inc. of Bayou La Batre, Alabama recently delivered the M/V IBOM, the second vessel in a three-ship order for SLOK Nigeria Ltd. The IBOM is a 200 ft Single Point Mooring Vessel outfitted to provide oil field abatement, fire protection and heavy lift service in the vicinity of offshore single point moorings in Nigerian waters. The vessel departed for Nigeria November 17, 2002. According to Horizon, IBOM is not only one of the largest vessels ever constructed and launched in Bayou La Batre, it is also one of the most sophisticated vessels ever constructed there.

The 200 ft x 56 ft X 18 ft steel vessel was designed specifically by Horizon to fulfill contract requirements between SLOK and Mobil Oil Producing Unlimited Nigeria. Precise navigation and position maintenance is accomplished through a set of Heimdel controllable pitch propellers installed in kort nozzles and controlled by a Beier Radio dynamic positioning system, which integrates the propulsive power of two Caterpillar 3516B main engines and three 500 HP side thrusters, two forward and one located in the stern.

Cunningham and Walker of Jacksonville, Florida performed the detail design of IBOM to Horizon's specifications. The vessel, surveyed and classed by ABS, is DP Auto and meets SOLAS requirements. The vessel has been fitted with dispersant booms on each side of the vessel to assist in oil spill support. IBOM is certified for an F1F1 firefighting capability with two remotely controlled 1200 M3/hr fire monitors installed above the pilothouse. Three Hydraulic cranes of 5, 5 and 10 ton are installed on the main deck.

IBOM's principal characteristics are:

  • Length 200 ft (61 meters)
  • Beam 56 ft (17 meters)
  • Operating Draft 14 ft (4.27 meters)
  • Fuel Capacity 106,700 gallons
  • Dp-1 System Station Keeping, Joy Stick Control
  • Propulsion Engines 2 Cat. 3516B at 2000 HP Each
  • Thrusters (2) Bow, (1) stern,
  • Marprop 500 HP Controllable Pitch Props HeimsL-90 inch 4 Blade
  • Generators (3) Cat 3412C 450 kW
  • Crew 12
  • Passenger Accommodations 22

Upon delivery to Nigeria, IBOM will be under contract to Mobil Oil Producing Unlimited, Nigeria. Horizon is the first U.S. contractor to construct a major offshore vessel for a wholly-owned Nigerian company. Horizon delivered a 155 ft aluminum crew boat to SLOK in January, and has a second 155 ft crew boat under construction for delivery in March 2003.

Horizon Shipbuilding, Inc. constructs vessels in steel, aluminum and fiberglass. In addition to the contract with SLOK Nigeria Unlimited, Horizon recently completed a contract to construct thirty-eight 27 ft fiberglass Towed Targets for the U.S. Navy and is currently performing another contract for the Navy to construct 15 fiberglass Trimaran Towed Targets. Horizon also has a contract for overhauling the Missile Retrieving Boat for the U.S. Air Force Panama City, Florida.
