• Consider delaying the operation until conditions are more favorable to the mission with the system.
• Consider sourcing a higher performance system.
22.1.6 Task list and guidelines
The trial-and-error method of learning new tasks, while effective, is costly and time-consuming. The learning curve for a task is greatly accelerated if one has the benefit of others’ experiences with trial and error regarding the selected task. The task listing below was developed from a menu of port and harbor security requirements. The procedures were tested to determine the best method of task approach to cut down on inefficiencies during mission planning and conduct.
The task list details a method for each general task classification. The general guidelines pro- vide for operations in the best-case scenario or under perfect conditions. Along with the general guidelines is a diagram and task description for accomplishing specific tasks as the conditions become less than ideal.
Once the task has been mastered by the ROV operator, modifications to the procedure certainly should be attempted (and, if successful, fully documented) in order to continuously update and improve these TTPs. Use the matrix below as a guideline for starting the task and modify as the sit- uation dictates.
22.1.6.1 Table of task expectations
The following categories are provided to help determine the equipment capability and level of pro- ficiency of the operator based on the planned task.
• P: Possible with operator of average proficiency
• D: Difficult with operator of average proficiency (possible but time-consuming)
• X: Difficult or not possible with operator of average proficiency (positive outcome questionable
or doubtful)
• NA: Nonapplicable.
The following OCROV sizes, as described in Chapter 3, were considered in the task matrix:
• S: Small ROV
• M: Medium ROV
• L: Large ROV
When performing the tasks described in the matrix, all items in the “P” category are suggested methods of approaching the task with the size of equipment indicated (S, M, and L). At the begin- ning of each task is a descriptive note suggesting the overall approach to the task. Then select the menu of procedures based upon the “P” items within the size category.
In practically all instances, the RB is the best platform of opportunity due to the proximity of its operating platform to the water’s surface, as well as its mobility and agility.
The detailed list of tasks examined in the matrix and sections to follow include:
• Ship hull inspections
• Pier inspections
• Anchor inspections
• Inspecting underwater obstructions
