Autoship and Autohydro Used in Offshore Platform Engineering
by Richard Roper, Naval Architect, formerly of Friede and Goldman
“More than 100 currently operating mobile offshore drilling units bear the F&G mark. With such a large number of designs in service, Friede and Goldman is called upon often to engineer upgrades that will press the fleet into greater depths in search of oil.
Autohydro is our tool of choice for melding the stipulated parameters into a set of sponsons for a given upgrade. Often the customer will specify a desired natural period, displacement, and loading condition. We have even used Autohydro to create a “Surface of Minimum Downflood Point Height”. This gave the owner of a drillship we upgraded this year the ability to immediately place a new vent or relocate an old vent, door, etc. in a safe position.
Autoship Systems products have also been an essential part of the process of designing new rigs such as the Smedvig SPU 380 for the Balder field in the Norwegian North Sea.
