Abstract EN
A thrust allocation method was proposed based on a hybrid optimization algorithm to efficiently and dynamically position a semisubmersible drilling rig.
That is, the thrust allocation was optimized to produce the generalized forces and moment required while at the same time minimizing the total power consumption under the premise that forbidden zones should be taken into account.
An optimization problem was mathematically formulated to provide the optimal thrust allocation by introducing the corresponding design variables, objective function, and constraints.
A hybrid optimization algorithm consisting of a genetic algorithm and a sequential quadratic programming (SQP) algorithm was selected and used to solve this problem.
The proposed method was evaluated by applying it to a thrust allocation problem for a semisubmersible drilling rig.
The results indicate that the proposed method can be used as part of a cost-effective strategy for thrust allocation of the rig.
