Max uptime for all assets OIL & GAS 2/2 Nini/Cecilie - development project valve). The system is made of stainless steel for use in zone 2 in accordance with Atex. Hydralic power package Semco Maritime carried out design and fabrication of two hydraulic power panels, one for each platform. The power panels deliver hydraulic pressure for systems: 600 bar, 400 bar, 200 bar, and 100 bar. Each system has its own hydraulic accumulator back up. The system is made of stainless steel for use in zone 2 in accordance with Atex. Power system The normal power source on the platform is 24 V DC from the battery banks. Once in 24 hours, normally at night, the battery banks will be charged from the diesel generator. By using the newest inverter technology, which has made it possible to supply the motor with AC power instead of DC power, Semco Maritime has improved the power system concept and consequently opened up the possibility of saving power and maintenance of the other unmanned platforms in the Danish sector. Instrument installation On board Nini and Cecilie the instrument safety system is programmed in a dual safety controller. Process and utility control are programmed in a single process controller. In order to save cable installation, remote input/output modules are used in panels and in the process area (EEXi model). Furthermore, bus communication (Profi and MOD bus) was used to the maximum extent possible. Onshore commissioning Concurrently with the finishing of the installation Semco Maritime carried out the mechanical completion. We used our own system that is based on the Norsok standard. When a system was mechanically completed, the commissioning engineer took over and together with the customer he carried out the commissioning in accordance with the onshore commissioning procedure made by Semco Maritime. Offshore commissioning When hook-up was finished offshore, our commissioning engineer carried out the offshore commissioning together with the customer and DNV.
