“…Ocean-bottom seismometers (vide EMSO-PT PILOT OCEANOGRAPHIC CAMPAIGN) were already deployed. The location of Aguçadoura in the northern part of the Portuguese mainland coast was chosen to support initiatives related with the blue economy: here the world's first wave-farm was tested in 2008, and it is an area prone to the installation of near-shore fish farming (e.g., Silva et al, 2018). The two EGIM to be installed in these observatories have already been submitted to factory acceptance tests and sea acceptance tests during 2021 being the deployment scheduled for mid 2022.…”

The Atlantic dimension of Portugal, with c. 1,700,000 km2 maritime area, led to the prioritization of the European Multidisciplinary Seafloor and water column Observatory - Portugal (EMSO-PT) in the national scientific infrastructures’ roadmap. In this work we present the EMSO-PT initiative: a research consortium joining 15 research institutions, with the aim of implementing a network of multidisciplinary underwater observatories in the Atlantic, as well as laboratories and data processing support infrastructures. EMSO-PT’s priority is to generate continuous scientific data on marine environmental processes related to the interaction between the geosphere, biosphere, and hydrosphere, and to develop new sensors and platforms which will extend ocean monitoring in the near future. Monitoring variables will include biotic and abiotic variables of the ocean floor and water column, namely temperature, salinity, turbidity, acoustics, currents, and dissolved oxygen. Data will be disseminated through European Multidisciplinary Seafloor and Water Column Observatory – European Research Infrastructure Consortiums (EMSO-ERIC) channels, allowing for the integration and open access of data acquired by all partners of EMSO-ERIC, and by the research community at large.

“…This solution enables to deploy a suitable protective base structure to adequately host aquaculture production system as well as the envisaged renewable energy production devices. Implementation of the wave energy converter devices additionally help to download wave forces effects on the platform structure thanks to the partial wave energy absorption and transformation at impact [11]. Because of the modular composition of the concrete caissons and in order to minimize construction costs, an optimized engineering process to deploy each module in the installation bay, to connect rigidly each other up to the final composition of the selected platform final shape before it is moved by tugs up to the final destination site, has been developed.…”

Aquaculture is currently the fastest growing food sector in the world and the open oceans are seen as one of the most likely areas for large-scale expansion [1], [2], [3]. The global demand for seafood is continuing to rise sharply, driven by both population growth and increased per capita consumption, whilst wild-capture fisheries are constrained in their potential to produce more seafood. A recently funded EC project, the Blue Growth Farm – BGF (GA n. 774426, 1st June 2018 – 30th September 2021) aims at contributing to this world need with an original solution. The Blue Growth Farm proposes an efficient, cost-competitive and environmentally friendly multi-purpose offshore farm concept. It is based on a modular floating structure, moored to the seabed, meeting requirements of efficiency, cost-competitiveness and environmental friendless, where automated aquaculture and renewable energy production systems are integrated and engineered for profitable applications in the open sea. In the present paper, the overall engineering approach developed to carry out the research work is presented, described and justified. Different technical and scientific challenges are addressed through an integrated industrial engineering design approach, where all disciplines are tuned to achieve the Blue Growth Farm main targets. These are represented by: i) guaranteeing expected nominal fish production thanks to advanced automation and remote control capabilities; ii) minimizing the pollution introduced at marine ecosystem level when exploiting the marine natural resources, whilst increasing the social acceptance and users community agreement; iii) maximizing the electricity production in the Blue Growth Farm potential installation area ecosystem to provide energy supply to the on-board electrical equipment and to dispatch the extra produced electric energy to the land network. Preliminary engineering design results are promising to demonstrate effective increase of safety and efficiency by reducing on-board human effort and consequently risks at offshore, thus to make commercial-scale open ocean farming a reality. The present paper introduces overall concepts and design methodology whilst other companion works submitted at OMAE2019 [4], [5], [6] provide insight of specific aspects of the Blue Growth Farm project elaborated during the first six months activity.

“…Also, better structural and operational reliability can be achieved through proper co-location of offshore energy facilities. A study by Silva et al (2018) showed that the wave energy converters can be used as the shelter for aquaculture installations to minimize the nearshore wave impact on the aquaculture cages. On the other hand, integration, is defined as a hybrid use of a single structure for multiple purposes, including infrastructure for aquaculture, wind turbine(s), and/or wave energy converter(s).…”

Sustainable use of the ocean for food and energy production is an emerging area of research in different countries around the world. This goal is pursued by the Australian aquaculture, offshore engineering and renewable energy industries, research organisations and the government through the “Blue Economy Cooperative Research Centre”. To address the challenges of offshore food and energy production, leveraging the benefits of co-location, vertical integration, infrastructure and shared services, will be enabled through the development of novel Multi-Purpose Offshore-Platforms (MPOP). The structural integrity of the designed systems when being deployed in the harsh offshore environment is one of the main challenges in developing the MPOPs. Employing structural reliability analysis methods for assessing the structural safety of the novel aquaculture-MPOPs comes with different limitations. This review aims at shedding light on these limitations and discusses the current status and future directions for structural reliability analysis of a novel aquaculture-MPOP considering Australia’s unique environment. To achieve this aim, challenges which exist at different stages of reliability assessment, from data collection and uncertainty quantification to load and structural modelling and reliability analysis implementation, are discussed. Furthermore, several solutions to these challenges are proposed based on the existing knowledge in other sectors, and particularly from the offshore oil and gas industry. Based on the identified gaps in the review process, potential areas for future research are introduced to enable a safer and more reliable operation of the MPOPs.
