Project:

Statoil’s Barent Sea Snøhvit gas extraction project

Background:

The Snøhvit subsea project is one of the biggest developments in the Norwegian sector for some years.
Remotely operated connectors were required for long term subsea use.

Solution:

Vector worked closely with ABB on the specification and installation guidance to achieve maximum benefit from Optima’s capabilities.
Optima connectors specially engineered to enable fitting by ROVs.
23 Optima connectors ranging (14” to 28”dia) to work at 3,000psi and at 350 metre depth.
Largest connector is a massive 28” NB weighs 5 tons with a 30 year design life.

Project:

Conoco JIP subsea mudlift drilling system to bring drilled cuttings and contaminants to the surface

Background:

Deep water drilling problems such as fracture gradients and pore pressures especially in ultra deep conditions leave contaminants in the pipeline corrupting the fluid and endangering valves

Solution:

A combination of triplex pumps to bring contaminants to the surface and a sea water drive to deploy an ultra-compact Optima subsea connector

Project:

Kvaerner BHP field subsea gas return isolation system

Background:

10,000 psi, remotely operated connector was required for permanent use

Solution:

Two compact Optima connectors were installed to form the metal-to-metal sealing connections for the gas return line, which could be closed as required by a TDU
