Marathon Launches Jackup Penrod 86 At Brownsville Yard

These four frames capture the launch sequence of the Penrod 86, a class 82-SD-C self-elevating offshore jackup drilling platform built by Marathon Manufacturing Company, Houston, Texas.

The shallow-draft c a n t i l e v er drilling unit was launched recently at Marathon's Gulf Marine Division yard in Brownsville, Texas.

The rig is rated for water depths up to 250 feet. When the remaining sections of its three triangular legs are added, thev will be 360 feet tall. The derrick and other drilling components have yet to be installed. The rig's cantilever design lets the derrick move out beyond the stern so that the rig can work next to permanent offshore p l a t f o r ms without putting the weight of the drilling package on these platforms.
