DPS & Closing the Door on Unnecessary Risk

(Photo: DNV GL)

The design of many DP vessels dates back to a time when there was limited understanding of how to make closed bus power plants fully fault tolerant. This resulted in a number of potentially costly incidents. This poor incident record eventually led to many operators preferring to operate with open bus-ties, especially for critical DP operations. In addition to cost and fuel efficiency burdens, open bus-ties can impose other restrictions on a vessel’s ability to carry out its industrial mission, often resulting in otherwise avoidable downtimes.

Uljanik Shipyard delivers the 26,000 dwt trailing suction hopper dredger 'Bartolomeu Dias' to Luxembourg's Jan De Nul S.A. This is the second such dredger constructed at the yard, with a LOA of 147.6 m and breadth of 30 m. The ship and the working equipment aboard Bartolomeu are powered by two main diesel engines, each having a power of 7200 kW, while the depth from which the material can be sucked lies in the 42-50 meter range. The dredger pump is driven by a two-coil electromotor of power 8 MW and controlled by two independent frequency converters.

USS Jacksonville Strikes Vessel, No Injuries

No one was hurt when the periscope on USS Jacksonville (SSN 699), a Los Angeles-class submarine, struck a vessel while operating in the Arabian Gulf Jan. 10 at approximately 5 a.m. local time. Jacksonville surfaced from periscope depth to ascertain if there was any damage to the unidentified vessel. The vessel continued on a consistent course and speed offering no indication of distress or acknowledgement of a collision. Damage appears to be limited to one of Jacksonville's two periscopes. The reactor remains in a safe condition, there was no damage to the propulsion plant systems and there is no concern regarding watertight integrity. A U.S. P-3 Orion aircraft conducted a search of the area and saw no debris in the water or vessels in distress. The airborne search of the area is complete.
