2. e Streamlined procedures When you write about procedures it sometimes becomes apparent that some procedures can be improved or changed to make them more effective A key advantage of a good manual is that you get a smoother functioning organization 6 e Improved of staff relations Buy bringing employees together to work on a manual will also provide them an opportunity to contribute with ideas on how to improve systems procedures and avoid misunderstanding e Increased commitment Employees involved in the process of developing a manual wil mostly also increase their engagement in the company and in their correspondences with the policies and procedures available Robinson amp Etter 2000 p 76 82 4 Making a manual The making of a manual is divided up into several different steps that should be done thoroughly The manual and its sections should be produced in a certain sequence This will help you to get a much better overview of the work It will also facilitate the process when you have a clear idea of its contents The theoretical parts before the actual writing is the basis for what the manual will include and how good it will be 4 1 Planning the Manual Many people start writing a manual without a plan It is tempting to quickly get progress but do not start on your project before you have a clear picture of what it is that you want to get across to the reader Plan your manual properly before you start wr

6. manual should be in accordance whit the charters criteria s and the company s TOMS manual The problem to solve was how to make the manual easy to understand and functional so that it would serve a purpose and it would be used The second part of the thesis or actually the first part when you read it is to make a collaboration on how to write a good manual and how to do it systematically There are many ways of doing this but I collected the references I found to be of value There are better and more complex ways to write a manual but the most important thing to keep in mind is that the end result should be great The thing I almost immediately realized was that you have to start by collection good information on how to write a manual and what it should contain Only after that should you start collecting information for the manual itself The information I collected on how to make a manual comes from different sources I only picked in my opinion the most important for this thesis I used them when writing the manual for Rem Mermaid I made the manual and the collaboration at the same time so I picked only thing that I thought that worked for the collaboration You have to decide the boundaries in which to stay or otherwise it will become hard to know when to stop Therefore you should start with a proper planning and only after that start to create the manual During this process I have gained a better understanding of how to organize th
7. p 11 Here are some questions you can ask about the readers e What is their job e Do they have a specific task e What is their education level e How much do they already know about the subject e Are they motivated Once you understand what kind of reader will use the manual it will facilitate the provision of information For example if the manual is used in the field you should take into account that it should be easy to carry Uploading the manual on to the internet or intranet is a good and easy way for everyone to get access to the manual 4 5 Make an outline and estimate the numbers of pages The first thing to make is an outline The outline shows the chapters sections and headlines The chapters sections and headlines should be addressed in the same order they are presented in Start with the chapters When you are satisfied with the list of chapters then list the sections in each chapter You should not be afraid to try different variations for the chapters some may need to be split or merge When you are satisfied with the chapters and sections then choose a suitable headline for each section Either list the headlines with one word or as a short paragraph A good way to identify potential manuals is to look at the manuals developed by other companies Many companies have placed their manuals on the Internet Use their manuals to create ideas for your manual Do not forget to list the title page table
8. which you can then edit Interviews and subject matter statements usually take a little longer to prepare but the facts are more reliable and can ultimately save you some time The people who will use the final manual are usually the best sources of information and should be consulted and involved as much as possible The success of the manual often lies with them In the choice of subject matter experts try to get representatives from different backgrounds levels of experience and geographic areas Robinson amp Etter 2000 p 15 If you need to write instructions for the operation or maintenance of certain equipment ask your subject matter expert to go through the steps in the use of the equipment Then you see how the whole process works and it becomes easier to write about it 10 4 7 The level of detail and the choice of words Consider how much detail that the reader needs Often you need more details for beginners because they are unfamiliar with the topic while experts may need general guidance Provide just the right amount of information because it will have a significant impact on the success or failure of your manual Obviously to determine the appropriate level of detail you need to know exactly who your readers are Having multiple audiences both beginners and experts will complicate the writing and it can result in you giving either too little or too much information Choose short everyday words If p

Thrust Allocation The force demands in surge and sway and moment demand in yaw from the controller 50 have to be distributed to each thruster as pitch and or RPM set points and if applicable directional set points The thrust allocation in the Icon system takes into account Available power on each bus bar The Icon system will not enforce thruster action that exceeds the available power Optimal thruster utilization in normal operations Turning rate of thrusters pitch and RPM response The direction of azimuthing thrusters can either be variable auto direction or fixed in a set of pre defined configurations Grouping of thrusters Two or more thrusters can be arranged to be working as a group The purpose is often to reduce changes in thruster direction In cases where thrusters cannot produce negative thruster force reverse direction this ensures that the thrust demand is fulfilled without unnecessary turning of thruster direction Fixed thruster direction configurations or variable thruster direction 51 e Forbidden sectors for thruster direction 3 7 4 Signal Processing All measurements to the DP system have to pass several levels of testing and processing before being used in the control of the vessel The type of testing and processing functions used is dependent on the signal source 3 7 5 Vessel Model Filtering and Estimation Oscillatory motion caused by waves will not be compensated by the thrusters main pr
