Netherlocks B.V. has been chosen to supply its trapped key interlocking safety systems by India-based Larsen & Toubro Ltd (L&T). The company has ordered Netherlocks products to secure and safeguard pigging operations for two major projects.

One, in conjunction with Cairn Energy India, involves 39 pig launcher and receiver systems along a cross-country pipeline. The other project is from L&T's Qatar office, with Qatar Petroleum for the SGP project, where initially 12 of the pigging systems will be protected by the interlocks.
