The new navigation systems are to be installed on four LNG carriers managed by Shell for Bonny Gas Transport, a fully owned shipping subsidiary of Nigeria LNG Ltd. Sperry Marine will supply the systems and perform all of the installations.

The ships being upgraded are LNG Finima, LNG Lagos, LNG Port Harcourt and LNG Bonny. Each is being fitted with VisionMaster FT X-band and S-band radars and two electronic chart display and information systems (ECDIS).

Two of the ships, LNG Bonny and LNG Port Harcourt, are also being fitted with dual fibre-optic gyro systems.

Sperry Marine also reports that it has received orders from Shell for similar retrofits of radar and ECDIS navigation systems on the tanker Helix and two other LNG carriers in the Australia LNG Ship Operating Company (ALSOC) fleet, Northwest Sandpiper and Northwest Seaeagle.

The Bonny Gas Transport LNG ships primarily trade on the Nigeria-Europe route while the ALSOC ships are on the Australia-Japan run.
