Offshore vessels are increasingly deployed during exploration and extraction of deepwater oil and gas reserves. Our comprehensive range of shipbuilding grades products and services are suitable for Floating Production Storage and Offloading vessels (FPSO), Floating Liquefied Natural Gas vessels (FLNG), and drilling ships.

At ArcelorMittal Energy Projects, we have a proven track record in supplying structural steel packages, both for hull, and topsides applications. Our products and services are supplied to project owners, shipyards and specialized topsides modules fabricators.

Products supplied for FPSO & FLNG:

  • Hull fabrication (plates, bulb flats and sections)
  • Topsides modules and turret fabrication (beams, seamless and welded tubulars)
  • Flowlines and pipelines
  • Mooring systems

Subsea structures

New platforms are being continuously installed in different parts of the world and operate in deeper and deeper waters.

A safe and efficient interconnection between the topside platforms and vessels, to the wellheads and pumps on the seafloor is necessary to guarantee reliable oil extraction operations.

ArcelorMittal Energy Projects provides steel solutions for the following structural subsea applications:

  • Pipeline End Manifolds (PLEM)
  • Pipeline End Termination Systems (PLET)
  • Subsea Templates
  • Subsea Manifolds and Mudmats
  • Pipe support structure

Our team has a proven track record in supplying structural steel packages for various subsea applications and a thorough understanding of the specific inspection, testing and quality control needs that are required in the subsea environment.

Our wide range of structural steel grades are offered either from our own stockyards or ex-mill. These grades are approved by all major classification societies such as ABS, DNV and Lloyds Register.
