offshore platforms (Maersk Oil and Gas, Denmark); most of these projects were
related to the following areas;
• TE- Load Shedding & Sharing System. Upgrade / Software Description. To
improve the function of the load shedding / sharing system, the actual
condition of the turbines has been used as a basis to calculate the available
power instead of the turbine nominal values. The actual condition value is
affected by four parameters; ambient temperature, the differential pressure,
maintenance time, and the mechanical degree.
Client: Maersk Oil & Gas, Denmark.
• DAN F- LV switchboard design. In this project, I have specified and
described the required LV switchboard including all its contents. Voltage
drop and short circuit calculation.
Client: Maersk Oil & Gas, Denmark.
• TW- Load Shedding & Sharing System / Software & Installation
Description. I have updated the system by considering the actual condition
of the turbines as in Tyra East. I have made new function block diagrams to
show the events sequence.
Client: Maersk Oil & Gas, Denmark.
• GORM C- Pre alarm earth Fault GC-SWBD-3KV. I have made a pre
warning earth fault system and test procedure for three cooling water pumps
to avoid the trip of both side of 3KV SWBD. This task has been done by
installing current transformer, current monitor and ammeter on each pump
feeder. To warn the operators in the CCR earlier about an earth fault
situation, digital alarm signals will be shown on the display VDU.
Client: Maersk Oil & Gas, Denmark.
• GORM C- Interlocks between upstream & downstream breakers. There are
six downstream breakers, which can be switched ON when the upstream
breakers are on the earth position, therefore it causes shutdown status. This
problem has been solved by installing new relays in the upstream breakers in
order to transfer a service signal and inhibit close signal to the downstream
breaker, so it will not be possible to switch the downstream breaker ON,
unless the upstream breaker is closed and its isolator is in service status.
Client: Maersk Oil & Gas, Denmark.
• TW- Distribution Boards Trace Heating. I have specified and described two
new identified distribution boards trace heating that should be replaced the
old trace heating boards, besides updating the MEL and the related
drawings.
Client: Maersk Oil & Gas, Denmark.
• T W- DOCwin Max. / Min. short circuit calculation. This project was a pure
short circuit calculation studying for whole platform (3KV switchboards and
LV distribution boards) by DOCwin program. The studying included the
maximum, minimum mode at normal and emergency operation
configuration.
Client: Maersk Oil & Gas, Denmark.
• Harald- DOCwin Max. / Min. short circuit calculation. This project was
pure short-circuit calculation studying for whole platform
(3KVandLVswitchboard) by DOCwin program. The studying included the
maximum and minimum mode at normal operation configuration.
• Harald- Power distribution to level gauge illumination. In this project, I
have specified and supplied nine level glasses that should be installed on

five different vessels. This project included a Max. & Min. short circuit
current calculation by DOCwin program.
Client: Maersk Oil & Gas, Denmark.
• SIRI- Load shedding and start up interlock system. I have done in this
project two packages (software & installation). The first package has been
done in coordination with Odense. I have determined the functional block
diagram (flow chart) and specified the priority table, which used by the load
shedding program to select the loads to be load. Load shedding program
reacts with three parameters; Power overload of generator, generator
winding temperature, and turbine operating temperature. We have used the
available power on the bus bars is the reference for program operation to
detect the necessity to shed the loads according to the priority table. In the
installation package, I have described an interface design for all signals that
required achieving the program properly. For this task, we needed the
current measurement (AI) and the open breaker signal (DO) for each load,
besides six (AI) signals from the generator control panel; Active Power
(KW), Reactive Power (Kvar), Total Current Value (Amp), Turbine
Operating Temperature (T54), Generator Winding Temperature (TWIN),
and the Ambient Inlet Temperature (TAMB).
