Here are some updates on the activities in the Centre. This is the first of a series of information notes which we intend to send you every other month from now on. We will highlight some of the latest achievements and link to more detail information on our website (linked information available to partners only - when logged in).
An updated presentation of Smart Maritime can be downloaded here, and information on ongoing activity and progress can be read from the Smart Maritime homepage.
We are looking forward to seeing you at the Network meeting next week, during which we will go through the main achievements of Smart Maritime so far, and together prepare for 2017. Please find here an updated program (with dinner on Tuesday at 7.30 pm).
MAIN ACHIEVEMENTS 2016
Main dimensions and hull form
Exploiting energy saving opportunities from slender hull design: Dr. Lindstad has studied the potential impact of the Panama Canal expansion canal can influence ship design and energy efficiency of the global merchant shipping fleet. Not only it will contribute to economies of scale, but also to energy-efficient designs.Read the article in Marine Technology here
- Haakon Utby did a master thesis on the optimization of hull shape of bulk and tank ships, taking into account also added resistance due to waves, and relieving the typical restrictions on main dimensions. The thesis shows significant savings by making the hulls more slender by increasing the beam. MSc thesis available here
Marine hybrid power systems
A draft report on Marine hybrid power systems and components is completed and will be sent to project partners for review. Additional input on component efficiencies may be required.
A simulator of the hybrid power lab has been developed, and can be used to estimate efficiency of the equipment for different operational point. A parameter identification method is also established. The next step is data collection for simulation model verification, with focus on losses in power electronics.
Fuel and abatement
Clipper Harald case study: HFO + Scrubber& EGR. Improved EGR quality is reducing need for turbine and heat-exchanger washing. New measurements and analysis of washing-water quality show very low levels of harmful components, due to the washing-water cleaning system.
LNG – Shortsea case: test on several ships on Pure gas operation. A test program has been performed in cooperation with Bergen Engines including particulate measurements.
Energy saving devices and technology: PROMAS
Effect of waves on Energy Saving Devices: in August 2016, model tests were carried out in MARINTEKs long towing tank in cooperation with Vard Design and Rolls-Royce Marine. The purpose of the model tests was to investigate the effect of waves, steering actions and off-design operation on the power savings obtained by using the PROMAS system over a conventional propeller/rudder. Results from these tests will be presented at the Network meeting on Oct 25th.
Analysis of full-scale data
A server system at MARINTEK has been established to ensure an easy and secure way to share monitoring data and accompanying relevant information. Per the exit of Q3 2016, full-scale monitoring data have been provided by Wilhelmsen, Grieg Star and KGJS. We very much appreciate this, and of course welcome more data.
This far, the project has concentrated on developing analyses methods for data collected with autonomous systems, because the autonomously collected data needs quite a bit of treatment before they can be used in our studies.
At MARINTEK, Prasad Perera is currently developing the necessary toolboxes to clean, filter and validate the received datasets. Matthias Nowak has been assisting Prasad in this work by appending environmental data from weather services based on the recorded vessel positions and time stamps. For this purpose, the same tools as developed under sub-project SP3 Virtual Testing in realistic operational profiles.
At NTNU, Msc student J.C. Gjølme did a summer internship on analysis of the in-service data logged on vessels operated by Grieg Star. The measurement data was checked and filtered, and combined with hindcast data for wind, waves and current. The objective of the summer project was to make and check an empirical model of speed loss (or power increase) due to wind and waves, using machine learning.
The main focus so far have been on developing an application for simulation of an integrated ship system, the GYMIR application:
GYMIR is an application for early-stage design assessment, simulating the long-term performance of a ship in realistic operational profiles
Models of different ship sub-systems can be integrated (i.e. Hull and Propulsion models from WP2 and Power System models from WP3)
The application is being developed by MARINTEK in cooperation with Vard, Havyard, Rolls-Royce, DNV GL and NTNU
The industry partners are currently testing the first version
GYMIR will be presented at the Network meeting on Oct 25th
Ship Transport Environmental Assessment Model: STEAM
STEAM – Ship Transport Environmental Assessment Model. A first test version of a tool for calculating life-cycle impacts for individual ships has been developed under the working title STEAM. The model enables impact studies of individual ships and its key modules will be tested in the upcoming period with specific LCA case studies. Further development will focus on scaling-up assessments from ship level to fleet level, to support development of the sector towards a two-degree target. STEAM will be presented at the Network meeting on Oct 25th
SFI management – new coordinator functions
To strengthen the Technical Advisory Committee, its involvement in the SFI's activities and interaction with the management team, Gunnar Malm Gamlem (e-mail) from Wilh. Wilhelmsen Asa is appointed by the Board as Coordinator for our Industry partners. His role will be to monitor the SFI activity from an industry perspective.
On the SFI management side, Agathe Rialland (e-mail) has joined the team as Administrative Coordinator.
New team members
Endre Sandvik joined the WP4-team (Ship system integration and validation) as PhD candidate. The title for the PhD thesis is “Simulation Based Design of Ships With Regards to System Performance”
Kevin Koosup Yum is new employed at MARINTEK and joined the WP3-team (Power systems and fuels). He is working on SP2 Hybrid Propulsion
Renato Skejic, post doc, will joint Smart Maritime on Nov. 1st. will focus on computation of added resistance due to waves, using potential flow methods
