SHIP-SHAPED OFFSHORE INSTALLATIONS
Ship-shapedoffshoreunitsaresomeofthemoreeconomicalsystemsforthedevelopment
of offshore oil and gas fields and are often preferred in marginal fields. These systems
areespeciallyattractivewhendevelopingoilandgasfieldsindeep-andultradeep-water
areas and locations remote from existing pipeline infrastructures. Recently, the ship-
shaped offshore units have also been considered for application to near-shore oil and
gasterminals.Thisbookisanidealtextandreferenceonthetechnologiesfordesigning,
building, and operating ship-shaped offshore units, within inevitable space (and time)
requirements.Thisbookincludesarangeoftopics,fromtheinitialcontractingstrategy
