Successful refit of Petrojarl 1

Thu, 08/24/2017

On the 18th of August 2017, Damen Shiprepair Rotterdam (DSR) and its subcontractors delivered the FPSO Petrojarl 1 to Teekay Offshore following a complete redeployment project taking place over the past 2 ½ years. 

The Petrojarl 1 has been operated by Teekay for 28 years in the North Sea and is now destined for the Atlanta Field in Brazil. After extensive engineering (over 450,000 engineering hours), more than 50% of the process equipment was removed and replaced by new and additional equipment, required to treat heavy oil at the new location in accordance with the most stringent specifications and Brazilian compliance requirements. The available deck space presented major challenges during engineering and execution of the work on board, which was done by Damen and its subcontractors. All workers returned home safely every day.

Croonwolter&dros: partner since 2015
Croonwolter&dros was one of the subcontractors working on this complex refit-project. Since February 2015 a team of experts has been working on the electrical installation of the Petrojarl. The scope of our work has been diverse. Croonwolter&dros was responsible for maintenance and testing of the diverse HV and LV systems, overhaul electric, propulsion and thruster motors and crane booms. Disconnecting old process installation skids and their installation components. Also installing several new process installation skids, also including the installation components, such as the cable trays, tubing, valves and safety measures. And installing several communication and navigation systems, such as Global Maritime Distress and Safety System (GMDSS) including antennas, and satellite communication (Iridium Inmarsat mini C). Assisting the yard with safety assistance by means of lock-out, tag-out (LOTO) of the complete electric installation of the vessel.

All this is successfully completed according to Offshore regulations and without any safety incidents, in order to help make the Petrojarl 1 a saver and more productive vessel.

Scope of the total refit
The self-propelled FPSO spent 14 months in Dock no. 8 (300x50m) undergoing refurbishment of its marine systems, underwater hull, seawater system, crane booms, heating coils in the cargo tanks  and specialized steelworks in the upper and lower turret areas,  which needed to be completely revised and adapted to suit the 1500 metre deep mooring location. Simultaneously, new designed high quality, prefabricated equipment skids containing heating, cooling, separation, compression, boilers, centrifuges as well as a new E-house with electrical equipment were placed on board. Interconnecting piping and cabling was subsequently installed to complete the topsides and connect it to the remaining facilities.
