UPA - Under Platform Access
The UPA provides access to the bracings, underside helidecks and side shells of offshore fixed platforms and rigs (Jack Ups and Semisubmersibles). Connection to the hull is by a framework mounted to the hull top and sides which is adjustable depending on the hull depth. A hydraulic power unit is included with the system, mounted on the maindeck of the platform/rig. Connected to the framework is a crane column with an extendable boom and 2 men working basket.
Easily mounted and relocated on the side of the hull/maindeck, the extending inspection arm offers a range of 31m to provide easy access to the complete under-floor and sides of the rig or platform, plus lower leg sections of Jack Ups. Work can be performed either offshore on location thus allowing reduced scope in shipyard and/or better preparation for the shipyard stay. Flexibility, safety and easy access are the key points of the UPA.
