DUTTON'S NAVIGATION
SHIP HANDLING AND RIG MOVING SCHOOL FOR JACK-UPS
In this time of increased demand for qualified personnel to move rigs, Dutton's Navigation has created a PRACTICAL rig moving school. The school's goal is to create a realistic forum for learning the basics and peculiarities of maneuvering drilling rigs in close quarters.
To date, all experienced rig movers initially started moving rigs during actual, customer dependant conditions. This has not only cost us time in the learning curve, but has needlessly put expensive contractor and customer equipment at risk.
Our rig moving school gives the student the opportunity to practice maneuvering rigs using scale replicas of tow vessels and rigs. It is our belief that understanding the shiphandling aspect of rigmoving is paramount. The system was developed to simulate conditions as real as possible. Each tow vessel is operated by a student. One student acts as the rigmover on board the rig during each evolution. Each tow vessel is sized to safely carry one person, the rig is normally manned by three persons. The models are not only scaled by weight and size, but are also weight to horsepower ratio correct to simulate actual conditions. The rigmoving environment has been designed to give realistic leg foundations for soft and hard bottoms. Provisions have been made to simulate loss of communication, parting of tow wires, and current and wind effects. Each class of four individuals will rotate through the ship handling section and have several opportunities to act as rigmover. There will be at least eight evolutions per class.
The class includes traditional teachings as well. There are sections on preloading, foundations, soil mechanics, RPD understanding and management techniques, anchor gear, anchor patterns, towing gear, rig move preparation, communication, and location surveys. But the main emphasis is on the actual forces, conditions, and procedures of safely positioning a Jack Up Rig using both tow vessels and anchors. The simulator is set up to expose the student to the physical and mental stress associated with the actual movement of drilling rigs.
Each rig mover will leave the school with a class "A", "B", or "C" rig moving certificate, and a written appraisal of the student's performance. This gives the student the opportunity to be evaluated by a knowledgeable rig mover, and gives the customer a valuable means of evaluating their employees.
The truth is, we (the industry) are still having accidents and the predominate cause is HUMAN ERROR.
