Offshore Platform Installation- Jacket Installation and Topside Installation

Oceanic 5000 is a DP2 Derrick Lay Vessel which can install offshore structures including jackets and topsides weighing up to 4400MT. The state-of-the-art Oceanic 5000 can also lay subsea pipelines utilizing her two double-joint stations resulting in considerable increase in lay rates. This video demonstrates installation of a 2000t jacket by launching method and a 1500t topside (deck) by lifting method.

The entire pipe lay assembly process is carried out below the main working deck. This allows maximum pipe storage above deck and more free deck space for structural installation; thereby providing a safer and more productive working condition.

The vessel is equipped with a specially-designed “piggy-back” system for the installation of carrier pipes to be simultaneously attached to the main trunk line during the lay operation.

The stinger is 74 meters long connected by a hinged A-frame to the stern.
The vessel is equipped with three 80T tensioners. The crane is designed to address the majority of lifting requirements including heavy lift installations, near shore lifting, and platform removal.

The lift capacities of the main block (4400mt at 37 meters) and the auxiliary block (800mt at 35 meters) enable the vessel to undertake an impressive range of projects. Moreover, the 3000T fully-revolving condition increases efficiency, workability and control of heavy lift operations.

Oceanic 5000′s relatively shallow draft provides access to work in shallow waters and fabrication yards. This versatility, combined with the ability to utilize both anchor and DP2 positioning systems, enable OMC the flexibility to perform the entire scope of work irrespective of water depths.

The vessel propulsion system, designed to transit at 12 knots, allows her to reach locations in a swift and cost-effective manner.
