Drilling units

Modern drilling units come in many shapes and sizes, from jack-ups and semi-subs, to fixed platforms and drilling ships. On a drilling unit, nothing is more important than safety, and each unit must comply with a variety of standards and regulations. Bureau Veritas supports its clients in staying current with all industry practices, requirements, standards and safety solutions.

Industry tendency is to build high-specification rigs for the deepest water and drilling depth. However, these rigs are expensive, and not cost-effective when underutilized or out of commission. Downtime, and any incidents leading to it, must be avoided. To ensure this, unit operators and owners require a partner familiar with all kinds of drilling units, subsea assets, and floating units to serve as an Independent Verification Body (IVB) and provide Safety Case Verification.

  • Bureau Veritas classes all kinds of units, including jack-ups, drillships, semisubmersibles and swamp barges
  • Our mobile drilling unit classification services verify the structural strength and integrity of essential parts of the hull and its appendages
  • Bureau Veritas Solutions works with units throughout the lifecycle, from design approval to decommissioning
  • We offer fully independent design review services
