This paper investigates the dynamic recovery policies for liner shipping service with the consideration of buffer time allocation and uncertainties. We aim to allocate the buffer time at the tactical level and then determine the optimal policy, including speed optimization strategy, port skipping and acceleration rate choice, for recovering from disruptions due to various uncertainties or random adverse events, which cause vessel delays. To achieve this, we attempt to obtain the optimal balance among economic, environmental and service-reliable objectives. A novel mathematical formulation is introduced to solve the robust vessel scheduling problem with short- and long-term decisions. Furthermore, we propose and test two heuristics to solve the proposed model. Experiments on the container liner shipping service show the validity of the model and some managerial insights are gained from them.

The Amalia lander is a modular gravity-based structure capable of executing different tasks in subsea conditions such as monitoring, surveillance and docking autonomous underwater vehicles, and could work as a platform for validating coatings, damage at foundations and scour protections and integrity of new materials, among other applications. This lander has a unique complex geometry and is made of the eco-friendly material polyoxymethylene, a high-performance thermoplastic of low cost, low density and high stiffness. This paper elaborates on the latest design developments of Amalia, including in situ material characterisation and numerical modelling activities, which focus on fulfilling the rising needs of the blue economy in the subsea engineering field. Material characterisation included tensile and Charpy impact experimental tests. The experimental curve was used to improve the numerical models (Ansys software). Full-scale data, obtained at Berlenga Grande Island, were used to compile design information on loads and boundary conditions in order to set numerical and experimental trials used to study Amalia's structural reliability. The Amalia lander was studied and its design was upgraded, the details of which are presented here. Further research showed that both the interface between the rod and the ballast weight and the bearing connection between the cage and the sphere fork can be improved.
