Two designs of a composite marine hatch cover were developed on the basis of the
design of a steel one. One of the proposed designs features composite structure made by
means of manual lay-up technology, and the other one is based on a truss composite structure
which can be produced by rod winding process. Selection of the most rational materials and
design parameters was carried out on the basis of finite element simulations and use of
parametric optimization methods. Results reveal the possibility of weight reduction by means
of using composites in the hatch cover, which is associated, however, with a comparatively
high cost.
