SIX YEARS EXPERIENCE WITH THE BREGA SINGLE ANCHOR LEG MOORING

The first SALM (Single Anchor Leg Mooring) was installed at Brega, Libya, in October, 1969. During the next six years over 229 million barrels of crude oil were loaded through the facility. In October, 1975 all components of the SALM, with the exception of the base, were removed and brought ashore for inspection, maintenance, and reinstallation. This was the first detailed inspection and maintenance of most of the components. This paper discusses pertinent experience gained during the first six years of operation of the Brega SALM. Several modifications were made to improve performance during previous partial inspection and maintenance actions and during the major inspection and maintenance of October 1975. The eye-to-eye connection between the anchor chain and the buoy was replaced in 1972 because of excessive wear. Changes have been made in the underwater hose system to improve reliability. The overall performance of the Brega SALM has been remarkably good considering its prototype nature. This paper also describes the findings of the first major inspection and maintenance of a SALM. The buoy and riser only required repainting. Some hose which had been in service for six years was in need of replacement. Although most underwater swivels were still serviceable, two swivels had developed minor leaks during the last year of operation. The universal joints were found to be in good condition.
