Choke & Kill Manifolds

Metalis Energy choke and kill manifolds are designed for use in the harshest of offshore environments.

All choke and kill manifolds and their component parts are manufactured under highly regulated industry product design and type approvals. All systems are fully certified in accordance with industry regulations and are witness tested by either ABS or DNV and certified for use accordingly. High pressure and high temperature are commonplace in todays’ offshore wells and drilling applications. All of our drill floor manifold, including choke and kill, have a proven track record in these environments.

Metalis engineers have years of experience in the design, project management and manufacture of high-pressure manifolds including choke and kill, mud, cement, wash down and well test manifolds. Our engineers have worked on a wide variety of manifold packages including several for high-pressure high temperature (HPHT) 6th generation semi-subs, designed to deal with the harshest offshore drilling environments in the world.

This vast experience combined with the very latest in 3D modelling software means Metalis provide unparalleled quality of service when supplying the perfect choke and kill manifold system for your needs. Metalis will work closely with you from the initial design stages right through to the finished product ensuring you have a manifold individually tailored to meet your exact specification.
