Anadarko Petroleum Corp. wants a fleet of at least six vehicles with armor heavy enough to stop AK-47 bullets at its natural-gas project in Mozambique. And it needs them soon. The company called for expressions of interest from potential suppliers of so-called B6 specification vehicles, and also wants associated fleet management services, according to an advertisement published in the Maputo-based Noticia.

Anadarko is expected to spend at least $20 billion on its project in Palma, near the Tanzanian border, where a shadowy insurgency has killed more than 100 people and destroyed hundreds of homes. The attacks reached an area a few kilometers from the company’s worker camp. Other oil and gas operators including Eni SpA and Exxon Mobil Corp. also have projects in Palma. Anadarko plans to reach a final investment decision on its Mozambique LNG project this year, and has already started a community resettlement project.
