E-Marine's cableship Niwa is ready for operation after its DP II upgradeE-Marine PJSC, the leader in submarine cable installation, maintenance and repair in the Middle East, today announced the successful attainment of CS Niwa after its upgrade to DP II, which will allow it to perform surgical operations in very close proximity to oil and gas platforms. DP II is a requirement for the installation, repair or maintenance of telecommunications and power cables in the oil fields in general and in the closest proximity to Oil & Gas platforms in particular.

"The completion of this CS Niwa DP II upgrade raises the benchmark for Oilfield cable services in the Gulf and Indian Ocean," said Omar Jassim Bin Kalban, Managing Director and CEO of E-Marine. "Cableship Niwa is now a very well qualified vessel for operating in the closer proximity to oil and gas platforms, ensuring the maximum safety and highest service levels for the Oil & Gas industry. This is a tremendous achievement and we look forward to extending these services across the region."

Dynamic positioning (DP) is a computer controlled system to automatically maintain a ship's position and heading by using her own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyro compasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position.

The computer program contains a mathematical model of the vessel that includes information pertaining to the wind and current drag of the vessel and the location of the thrusters. This knowledge, combined with the sensor information, allows the computer to calculate the required steering angle and thruster output for each thruster. This allows operations at sea where mooring or anchoring is not feasible due to deep water, congestion on the sea bottom (pipelines, templates) or other problems.

The cableship Niwa is capable of servicing platforms anywhere in the Arabian Gulf and also off the coast of East Africa. It has a gross tonnage of 13,201 tons with a cable uplift capacity of 6098 m/t and a speed of 15 knots. It can accommodate up to 138 Persons and can be at sea for a continuous period of 60 days.

All crew are duly experienced in cable installation and repair, as well as in undertaking all marine offshore oilfield activities. The vessel is manned by sufficient and qualified crew to guarantee twenty-four hour operation.
