Offshore Service Vessels (OSV) are utilized for demanding offshore operations often under challenging conditions, e.g. Anchor Handling Tug Supply vessel (AHTS) supporting offshore drilling rigs and Offshore Construction Vessels performing subsea installation. The OSV case in the HOLISHIP project has addressed both these vessel concepts with the mai...

The present article introduces a holistic approach to ship design, as it is being developed in the Horizon 2020 EU project HOLISHIP (www.holiship.eu). The project deals with the development of design and virtual prototyping simulation platforms, which integrate software tools for all major ship design disciplines and optimization objectives, namely...

We examine the fuel savings of Edda Passat, a newly constructed wind farm support vessel that utilizes a common direct current (DC) grid. This enables its diesel engines to operate at variable speeds by using frequency converter technology. A detailed investigation of these benefits has been performed based on real-life measurements from three mont...

The present paper introduces an innovative, holistic approach to ship design and the development of integrated design software platforms and tools, which are used in practical applications. The paper demonstrates a subset of HOLISHIP's functionality by brief presentations of typical case studies. HOLISHIP is the joint effort of 40 † European mariti...

The present paper introduces the HOLISHIP approach to ship design and demonstrates a subset of its functionality by brief presentations of several case studies. HOLISHIP is the joint effort of 40 European maritime RTD stakeholders, funded by the Horizon 2020 EU framework (www.holiship.eu). It sets out to substantially advance ship design and to dev...

Here, we present the R&D project Real-Time Digital Twin for Boosting Performance of Seismic Operations, which aims at increasing the overall operational efficiency of seismic vessels through digitisation and automation. The cornerstone in this project is the development of a real-time digital twin (RTDT) — a sophisticated mathematical model and sta...

In many marine applications, modern high-performance synthetic fibre ropes have replaced, and are continuing to replace, well-known steel wire rope solutions due to the low weight of the synthetic ropes removing limitations for operations at large water depths. In some cases, replacement of steel wires with synthetic ropes has caused permanent defo...

This chapter describes modelling and optimization of machinery systems in a holistic design process. After descriptions of the main components and typical architectures of power systems are introduced, a holistic approach to power system modelling is discussed. Then a three-step process for optimization and verification of a machinery and power sys...

This paper gives a summary of the 250Te FRDS (fibre rope deployment system) joint industry project (JIP). The background for the project is the industry's need for lifting capacity of 250Te in 3 000m of water depth as expressed, for instance, by the DISH (deepwater installation of subsea hardware) JIP. The main objective of the 250Te FRDS JIP was t...

ODIM Alitec has developed a patented cable traction control unit-based (CTCU) fiber rope deployment system, which has been successfully used in ultra deepwater installation contract in the Gulf of Mexico by Subsea 7, one of the world's leading subsea engineering and construction contractors. The system has been deployed on the Subsea 7 offshore con...

The industry trend of more oil and gas exploration in deep and ultra deep water has put focus on finding faster and cheaper methods for installation and construction work at these water depths. One significant driver in this picture is the weight of the lifting line. The weight penalty of steel wire is increasing rapidly with depth, and is becoming...

The introduction of distribution automation is studied by many utilities at the moment. In some countries or in some areas, utilities are quite mature with respect to distribution automation (DA). Most utilities are however in an introductory phase with pilot installations. The primary incentive for DA is to increase the quality of supply, but obvi...

This paper describes how deregulation of the European energy market will force electric utilities to focus on efficiency and power quality. The MV and LV distribution network will be an important target for utilities to reduce life cycle cost and increase customer value. The authors describe how ABB have prepared for this new market environment by...
