HOUSTON – CNT International (Olowi) has awarded Tideland Signal a fast-track contract to supply navigational warning systems for Saipem’s wellhead towers and platforms on the Olowi oilfield off the coast of Gabon.

The three platforms will each be marked by two 10-mi (16-km) lights and a fog signal with a range of 2 NM, monitor/alarm panel, solar panels, and battery boxes, all skid-mounted and certified for use in Zone 1 hazardous applications.

Both lights are provided by Tideland's ML-300 EX lanterns, a lightweight, corrosion-resistant design featuring a one-piece acrylic Fresnel lens capable of achieving up to 7,288 candela. The lanterns are equipped with Tideland’s LC6EX six-place flasher/lamp changer equipment, which provides up to 256 user-selectable flash codes and maintains constant lamp power over a wide range of input voltages in order to conserve battery power and maximize lamp life.

The Tideland AB-68 EX fog signal incorporates six drivers/emitters producing 133.4 dB at 1 m (3.2 ft) equivalent and with a usual range of 2 mi (3.2 km). It broadcasts a 360º sound beam in the horizontal plane, with a pre-selected code. The drivers/emitters are housed in manganese bronze enclosures and are mounted in a stainless steel structure designed to withstand severe storms and harsh marine environments, the company says.

The field will be developed by Saipem using three wellhead towers and one conductor support platform tied back to an FPSO. Saipem's contract covers engineering, procurement, construction, installation, hook-up, and commissioning of the fixed portion of the Olowi production facilities as well as the installation of an interconnecting subsea pipeline, riser, and umbilical systems between the wellhead towers and the FPSO.
