Drillship Nereus Specifications

Type Ultra-Deepwater Dual

Activity Panamax Drillship

Shipbuilder US Shipyard

The owner of this vessel desired a drillship capable of traversing the Panama Canal, and able to drill world- wide, excluding ice-covered seas, in up to 10,000 ft. of water. In addition, the owner stipulated that this vessel must be capable of conducting an extended well test, therefore requiring the vessel to carry up to 200,000 bbl of crude oil.

Nereus was designed with cost and production in mind.

The hull form is simple, with a flat plate bilge and cylindrical bow. There is no complex curvature in the hull, which simplifies production. For a ship of this size, keeping cost to a minimum was a significant con- sideration for the owner.

There are six center-line cargo tanks. A two meter dou- ble bottom extends the length of the ship, as well as six meter wing tanks, port and starboard. These tanks, along with the forepeak tank contain 65,000 cu. m. of ballast capacity. The fuel and lube oil tanks are locat- ed directly below the engine room aft.

Nereus is a dual activity drillship. The forward rotary is used to assemble the riser, while the aft rotary or mousehole is used to join stands of drill pipe and col- lars. Two conveyors, one forward and one aft bring pipe and riser to the drill floor. This design feature dra- matically reduces the time required to drill a well. Two vertical pipe rackers service the rotaries, standing back pipe and casing in a large shared setback area. Four 80 ton knuckle-boom cranes are used to handle the pipe and riser on deck. The derrick is I rated for 2,000,000 lbs.

Located on the main deck is the mud module, the

Signal Wins GlobalSantaFe Contract

Signal International won a contract from GlobalSantaFe for the upgrade and modification of the GSF Adriatic II jack-up drilling unit. It is being modified prior to deployment in West Africa. The project will be performed in Signal's West Yard facility in

Pascagoula, Miss. The rig is scheduled to arrive April 15, 2004.

Pride Awards Mad Dog Contract

Pride International awarded Signal International LLC a contract to outfit and integrate the drilling equipment for BP's Mad Dog truss spar production facility in Green Canyon Block 782. The drilling support module (DSM) for Mad Dog arrived at Signal's Port

Arthur, Texas, facility on Feb. 1. The unit will then be integrated and commissioned with final load-out and redelivery anticipated in mid-May. Pride is operator of the drilling rig. J. Ray McDermott is constructing the 16-slot truss spar.

Rutter to Supply VDR's to White Rose Tankers

Rutter Technologies Inc. said that Knutsen OAS Shipping A.S., the owner/operator of the two shuttle tankers for the White Rose project, has selected Rutter VDR's for their vessels, as well as our Sigma S6 radar processing systems. The two shuttle tankers are being constructed at Samsung Heavy Industries, located in

Seoul, Korea, and are scheduled to be delivered in 2005.

Stolt Offshore Settles Patent Dispute

Stolt Offshore S.A., said its long running U.K. litigation with a competitor regarding a European patent covering technology related to the laying of flexible pipes, has been settled out of court. The settlement involves a cash payment by Stolt Offshore in respect of past patent infringements and the granting of a licence under the disputed patent covering the North Sea area. cement module, the extended well test module. The mud and cement modules are located directly above the bulk and sack storage areas.

The bulk materials are stored in p-tanks. The sacks are palletized, and a forklift is used for handling the pal- lets.

This vessel is dynamically positioned by six thrusters.

The controls system meets DP3 requirements. The thrusters are powered by six Wartsila diesel generators.

These gensets are capable of producing enough power for the vessel to travel at 15 knots at 80% MCR.

The accommodations are designed for a crew of 126, with separate facilities, when appropriate, for men and women. A helideck is located on the top of the deck- house. and is sufficiently large for a Sikorsky 61N or a

Boeing Chinook to land safely. ^•No. 1 in maritime equipment

Smart Radar Level

Sensor with Generic

RS485 Output

The first flat array antenna for liquid tank gauging.

This software driven array allows for each sensor to remotely configure itself for the type of product as well as the structural characteristics within each tank. It is completely self-diagnostic and is factory calibrated using a laser interferometer to .1mm. It is designed for the harshest environments and can be provided in a high temperature version to 385°F. It is intrinsically safe with Class 1, Div. 1,

Group D & C approvals. As a smart sensor, all processing calculations and software are resident in the device itself, only a high level generic data output, i.e., RS485 (or others on request) is sent to the cargo control area.

Options: • Multiple alarm set-points • Temperature • PV Pressure • I.G. Pressure • Tank Management Software • Automated draft and trim
