Year: 1997 Language: english Author: John F. Flory, Henry A. McKenna Genre: Technical book Publisher: Naval Surface Warfare Center Format: PDF Quality: Scanned pages + text layer Pages count: 228 Description: This is a feasibility study of single point mooring (SPM) systems for the Mobile Offshore Base (MOB) in water depths up to 10,000 ft (3000 in). The MOB is a very large semi-submersible platform, about 3000 ft (1000 m) long, with a displacement of about 700,000 tons. It will be equipped with thrusters and a dynamic control system. The mooring will be used in mild environments without thrusters, in moderate environments the thrusters will assist, and in severe environments the MOB will leave the mooring. Three alternative moorings were investigated, a Single Catenary Leg Mooring (SCLM), a Multi Catenary Anchor Leg Mooring (MCALM) (also known is turret mooring), and a Catenary and Single Anchor Leg Mooring (CASALM). The CASALM consists of a riser extending down from the MOB to a weighted junction suspended above the sea floor, and legs extending from this junction to anchors on the sea floor.

Description: This is a feasibility study of single point mooring (SPM) systems for the Mobile Offshore Base
(MOB) in water depths up to 10,000 ft (3000 in). The MOB is a very large semi-submersible
platform, about 3000 ft (1000 m) long, with a displacement of about 700,000 tons. It will be
equipped with thrusters and a dynamic control system. The mooring will be used in mild
environments without thrusters, in moderate environments the thrusters will assist, and in severe
environments the MOB will leave the mooring.
Three alternative moorings were investigated, a Single Catenary Leg Mooring (SCLM), a Multi
Catenary Anchor Leg Mooring (MCALM) (also known is turret mooring), and a Catenary and
Single Anchor Leg Mooring (CASALM). The CASALM consists of a riser extending down from
the MOB to a weighted junction suspended above the sea floor, and legs extending from this
junction to anchors on the sea floor.
