Waller Marine to Build Cable Lay Barge

Waller Marine, Inc of Houston, Texas has contracted to design and construct a dynamically positioned Multi-Purpose Cable Lay Barge for Rockson Engineering Ltd. of Port Harcourt, Nigeria. This EPC contract requires Waller to provide the turnkey supply of the barge and all specialized cable storage and lay equipment delivered to Nigeria ready to operate in the fourth quarter of 2004. The vessel, to be named "Shining Star" will be designed to lay electric cable, fiber optic cable and umbilicals in the rivers and coastal estuaries of Nigeria and in offshore waters up to 300 meters water depth.

The ocean going barge is designed specifically for cable lay service; having dimensions of 275 x 75 x 16 ft. the vessel will be classed by Lloyds Register, meet all IMO requirements and be flagged in the Republic of Panama. Specially designed cable lay and cable storage machinery manufactured by Parkburn Precision Handling Systems of the UK will include linear tensioners, cable drums and a 2000-ton dual-purpose cable carousel capable of feeding electric and fiber optic cables simultaneously. A deck mounted 100-ton crane and a 40-ton dynamic "A" frame fitted with a cable lay and burying sled for up to eight feet depth below the sea bed round out the barges cable lay capability.

Accommodations are provided for 37 crew and company personnel in single and double cabins complete with recreation, exercise rooms, laboratories, hospital and modern galley and mess. The facilities are fitted with a helicopter deck and capability of resupply from water borne supply vessels.

The barge will be constructed to Lloyd's Class DP AA dynamic positioning capability, using six diesel-hydraulic thruster units manufactured by Thrustmaster of Texas, with controls installed by Kongsberg DP Systems. Positioning and station keeping is augmented by a four part mooring system. Construction will take place in a Gulf Coast shipyard.
