Today's offshore drilling environment is progressing into water depths in excess of 10,000 feet. The DW HD H - 4 and SHD H - 4 connectors, paired with VetcoGray's DMS - 700 and SMS - 700 wellheads, are specifically designed for use in deepwater and other critical service applications where high bending loads are anticipated.

Product/System Overview

The H - 4 family of subsea connectors, introduced in 1964, is in use in every major producing region of the world, and in every type of offshore environment. The VetcoGray family of H - 4 connectors is field proven, hydraulically operated metal-to-metal sealing connectors and are widely used for:

• BOP stack to wellhead
• LMRP to BOP stack
• Completion tree to wellhead
• TLP/subsea template tieback
• Production riser assembly to subsea manifold
• Single point mooring to anchor base
• Caisson completions and artificial island drilling
• Specially adapted applications

Ideal for deepwater use, the H - 4 line of connectors has reliable, simple operating characteristics; excellent bending and tensile load capabilities; and a long, economical service life.
