Getting Your Dynamic Positioning (DP) License
Here you are, fresh out of the academy with your watch keeping ticket, & you are looking to get the additional DP endorsement. Or perhaps you have been at sea for 20 years & feel its time to try something new. Or maybe you can just see which way the wind is blowing.

Green Dynamic Positioning Technology
As positioning capabilities have been improved to the point where a vessel can now sit on a (virtual) dime, the focus now shifts towards refinement. Making vessels more efficient is not only the right thing to do for the environment, it also makes good business sense. As legislation continually moves towards stricter emission controls, companies that are taking the initiative now will remain ahead of the curve, staying competitive in the process.

Dynamic Positioning 101- Heading alteration and speed
This week we are going to look at a particular DP function, when using the Kongsberg system. Although it is a fairly simple point it is one that can still cause some confusion, even for some experienced operators.
That function is changing the ships heading while the center of rotation (COR) is is offset from the vessels center of gravity (CG).

Joining a New Vessel as DPO
Joining a new vessel can be a very exciting time. There are new people to meet, tasks to complete & food to eat! You may already have experience with the type of work that vessel performs, or it may be completely new to you. Either way, it is up to you to become familiar with the ship and the onboard culture as quickly as possible.

What Jobs are Done with Dynamic Positioning?
What kind of work is done using Dynamic Positioning?
What started out as a technology designed to position drillships in deep water has trickled down through the offshore industry & can now be found installed on all types of vessels. It is being used today in capacities never imagined back when it was first invented. In this series we will take a look at how the technology is being utilized & some examples of ships on which it is installed.

J. Ray Acquires 50% stake in NO102
The 427-foot NO102 should enable J. Ray to be an immediate player in the flexible pipe installation market. J. Ray expects to take delivery of the NO102 in the third quarter of 2010 following completion of the current vessel charter. The vessel has two cranes and a moon pool to support deepwater subsea construction work and has a fast transit speed. It is currently equipped with a 7,000-ton capacity cable, umbilical and flexible pipe carousel with horizontal lay system. J. Ray plans to further upgrade the vessel's capability by installing a high-capacity flexible-lay system for ultra deepwater installation work. The upgrade will include installation of a new 250-ton crane.
