Many different sensors have been installed on board vessels, a new framework is urgently needed to form a Common Operational Picture (COP), to assist the on-board operations and onshore analysis. In this paper, based on the Visual Analytics framework, we present a spatiotemporal dimension reduction method based on a real world case of oil combat operation. With our prototype, we show that how dimension...
Marine aquaculture is deeply rooted in Norwegian national economics and traditions, especially in the M⊘re og Romsdal region. This paper presents the development of a novel ROV for aquaculture inspection in marine application to provide first-hand information in fishery nets. The ROV is a part of so called “Sea Farm” project. When the ROV doesnot work, it will be carried by a floating platform. A...
The enormous amount of data collected from different sources in an Industrial Internet of Things (IIoT) will have to be processed, analyzed, and visualized in a timely manner. In this paper, we present a strategy for organizing IIoT data to facilitate data processing, storage, analysis, and visualization based on a typical oil combat operation scenario. A web-based system has been implemented and...
In this paper, a new meta-heuristic optimization algorithm called Grey Wolf Optimizer (GWO) is applied to offshore crane design. An offshore crane is a pedestal-mounted elevating and rotating lifting device used to transfer materials or personnel to or from marine vessels, barges and structures whereby the load can be moved horizontally in one or more directions and vertically. Designing and building...
This paper presents the development of a bio-inspired swimming robot from concept design to simulation for marine aquaculture applications. Based on investigation of several fish motions, the Manta ray is found to be the most suitable mock object since the flapping pectoral fin features long-endurance, low noise, high payload capacity, good stability and maneuverability. Through a comprehensive analysis...
This paper presents an analyzing and modeling scheme that can dig into the ship sensor data to generate models for ship motion prediction. As the raw sensor data contains information that is noisy and discontinuous, three data cleaning methods used for noise reduction, data continuing and resampling are developed. According to specific ship applications, various ship motion constraints are designed...
This paper will focus on typical diesel electric propulsion systems found on board offshore vessels. The offshore vessels category include vessels such as PSV (Platform Supply Vessels), AHTS (Anchor Handling Tug Supply vessels) and CSV (Construction Support Vessels). In short at least all thrusters and often also the main propulsion is electric. Hence, the electric energy is produced on-board by medium...
This paper describes the rapid prototyping of a low cost remotely controlled unmanned surface vessel (USV) intended for inspection of aqua farms. There is an increased focus on inspection of ocean-based aqua farms due to three major challenges: escaping fish, sea lice, and algae. Escaping fish may bring diseases to other fish or interbreed with wild fish and damage their gene material. Sea lice is...
Big Data Analytics (BDA) and Internet of Things (IoT) are rising quickly. The recent emerging Industrial IoT (IIoT), a sub-paradigm of IoT, focuses more in safety-critical industrial applications. Studies showed that the adoption of BDA increase companies' output and productivity; IoT enables companies to have more information and control in physical resources, processes, and environments; BDA and...
