Connectors

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.
