Abstract

With the growth in renewable energy, there is an increasing focus on offshore wind. Currently mostly fixed offshore structures are installed in shallow water, but the technology is improving and the turbines are expected to move to deeper water with stronger more frequent wind. The challenges of floating offshore wind turbines are very similar to those of the offshore industry. It requires safe and economic design, production, installation, maintenance, repair and removal.

In 2011, MARIN tested three different floating wind turbine concepts for the University of Maine-led DeepCwind project. The floaters include a spar buoy, a tension leg platform and a semi-submersible. The model tests were conducted to calibrate and validate simulation codes for floating wind turbines. Therefore, great attention was paid to the coupling between aerodynamic and hydrodynamic behaviour. We will discuss the chosen test and simulation approach, lessons learned and recent developments for testing of offshore wind turbines. 




Short bio:

Arjan Voogt holds a MSc. degree in applied physics from Delft University of Technology and graduated in fluid dynamics. He joined MARIN in 1998 to work as project manager on offshore model tests. Arjan is currently working as manager of MARINs satellite office in Houston. From this office MARIN provides local client support, third party verifications work and design optimization studies using in-house developed software.

Abstract

The HiLoad Technology for Offshore Loading and Mooring has been developed by Remora over the last 12 years. Remora is currently in the final process of entering into a 10-year contract with Petrobras in Brazil for the first HiLoad DP vessel where the operation in Brazil is scheduled to start in Q3 2013.  

Remora’s co-founder, Mr. Svein B. Hellesmark will in his presentation describe the entire step-by-step technology development process carried out by Remora from the initial “napkin idea” until a fully commercial vessel. The HiLoad DP is today a recognized offloading solution by a number of Oil Companies.

The motivation for developing the HiLoad Technology was to obtain a solution to enable safe offloading of crude oil directly from Spread Moored FPSO’s onto Conventional Tankers. With such a solution, the crude oil can be exported directly from the FPSO’s without any need for transshipment of the crude oil or use of remote deepwater CALM buoys connected to the FPSO.

The main need for such a solution is in Brazil and West Africa, but the trend is moving more and more towards an international crude oil trade and the need for such FPSO export solutions may be required at multiple areas of the World in the next coming decades.

The main focus of the presentation will be to describe the development of the FPSO Offloading System – the HiLoad DP. 70.000 engineering hours has been spent by Remora and in total 7 different Model Test has been carried out in the period from 2001-2010 to validate the function of the system and to obtain the most reliable hydrodynamic data for the vessel. Furthermore, a number of advanced computer simulations have been carried out during the 12-year development. Mr. Hellesmark will walk you through each of the main steps in this process during his presentation.

Biography

Mr. Svein B. Hellesmark
Remora

Mr. Svein B. Hellesmark is the co-founder of Remora and is today Technology Manager of the company as well as heading Remora’s office in Houston. Svein has 20 years experience in the oil and gas industry where he the last 16 years has mainly been focusing on FPSO Offshore Loading and Mooring Systems.

 

Svein has managed the development of the HiLoad Technology from the first initial idea in year 2000 until a fully commercial HiLoad vessel in 2012. This includes a number of Model Test and simulation projects carried out in cooperation with various Oil Companies. He has also been granted a number of International Patents related to the HiLoad Technology.

 

Svein is an active member of SPE’s OTC Committee with responsibility for organizing Technical Sessions at the Offshore Technology Conference in Houston, where he has been serving as Chairman for several sessions since 2010.

 

Mr. Hellesmark has been leading Remora’s activities in Brazil over the last 5 years where Remora now is in the final process of entering into a 10-year contract with Petrobras for HiLoad DP.

 

Svein graduated from the University in Agder in Norway with a BSc in Civil Engineering in 1992 and a BSc in Naval Architecture the year after. He also received his CAND.MAG. degree in 1993.
