Flexible Riser and Mooring System Develops Small Oil Fields in the North Sea

Abstract

The Flexible Riser and Mooring System (FRAMS) provides a technically feasible and commercially attractive method of unlocking small U. K. North Sea oil fields. A moored 60,000 OWT oil tanker, fitted with deck mounted production equipment is restrained by a mid-water bu::>y, while the swivel-less riser bundle conveys well fluid from, and injection water to, the subsea wellheads. In severe weather, oil production is stopped, and the tanker disconnects from the mooring, re-connecting when weather allows.
