The Markets

The markets for STS products are mainly for offshore vessels located worldwide in various oil fields. To keep STS in the market our products require continuous improvement as per customer needs. The graphs and tables below show the world market for supply vessel s to which our products will be fitted to. The customer need to dock vessels safely at all times, loading and discharging cargo at ports and at oil rigs at specified time and in different conditions of weather, i.e. rough seas heavy currents. Delivery of cargo at required times to the rigs and ports. In addition to that is safety, environment protection and finally the economical running of their business.

Trends in the Offshore Vessels Sector

Presently we are concentrating on the offshore market.

Years

Customer objective: Swing-up azimuth thrusters in the TCNS series have long been part of product portfolio, and these units have now been designed to give the ship designer more freedom. The attractions of the TCNS type of thrusters have been well appreciated by the marine community. Fitted as a bow or stern thruster, it can be swung up into a recess or ‘garage’ when not in use. When in the lowered position it provides a powerful thrust in any direction for manoeuvring, position-keeping or get-you home propulsion. A variation on the same principle, the Combi thruster, is particularly popular with some offshore vessel operators. Here the thruster swings up into a transverse recess forming a part tunnel in the hull where it can also function as a powerful tunnel thruster giving side thrust alone when raised. The swing-up unit in a module comprising the raising and lowering mechanism and the complete housing garage.

Products

STS produces the azimuth- swing up thrusters which can be used to meet good maneuvering in ports and station keeping (Dynamic positioning), as well as in transit. Therefore the thrusters shall have capability different from those produced before, that is, shaft driven and non rotating thrusters as well as those produced by our competitors.

The customer`s needs and requirementsThe customer needs to be supplied by two types of Thrusters. These are Bow thrusters and Swing up thrusters. The customer is customized his products so as to meet his expectations and eventually make her ship sail as per plan. The requirements for the customer are to observed because he wants the thrusters which can be easily installed, provide maximum bollard pull, effective maneuvering under all sea condition and eventually serve the purpose.Bow thrustersHe has planned to make use of bow thrusters when maneuvering in narrow channels in a short time in order o avoid dangers or sailing aground. These thrusters give her ship an ability to move sideways and negotiate corner in a very fast and safe way.Swing up thrustersThe customer intends to be supplied by swing up thrusters due to nature of his day to day operations at sea. It is a offshore supply Vessel (Customer) freighting cargo from the port (Shore) where it is shallow water to the rigs where there are number of marine cable and other ocean engineering structures. For that matter the customer requires to be secured with all dangers when her ship is

sailing at those two respective areas. The swing up and down thrusters is the solution for her intended goal. However this type can also be used on open sea where there is no danger when sailing at reasonably sea depth.

Technology

The thruster can swing up into housing in the hull when not in use and can swing down to horizontal position. In operation works as azimuth thruster and is designed to develop maximum bollard pull in the maneuvering, or to provide positioning power for station keeping. The thruster has an added benefit of functioning as a get you home drive. The thruster can be turned vertically in the upper position and be used as a tunnel thruster. Most drive and steering spare parts are compatible with existing TCNS units. At the same time the steerable underwater unit has been redesigned and updated. To rationalise spares and service, components are now common to other latest generation propulsion products. Emerging market requirements are for more power from this type of thruster installation, so it has responded by increasing the rating of the type 73 from 880kW to 1,000kW, while the new version of the larger TCNS thruster previously type approved for 1,800kW now has a 2,000kW rating.

When the thruster is stowed doesn’t protrude below the vessels baseline, this helps in shallow water operations. Our company STS can deliver two variants 73 and 92 types. Due to accuracy the thruster shall be delivered to shipyards in an assembly module and hull module that will interface assembly module and the hull ready to be easily welded into the ship at any yard. The thruster will have an advantage of standardized modules due to common parts and assembly line.

In order to ensure the thrusters during the operation the Company STS has designed the thruster guard which can protect the propeller when operated in areas covered by the Ocean Structures or shallow water. This can happen when the Navigator or Captain fail to make use of swing up action and cause the propeller to hit the ocean structures and cause great loss.

However FG has introduced the alarm system which can detect any object (danger) around which can be knocked by the thruster, the detection is reported immediately to the Navigator in order to take preventive measures.

Effective Emergency Action

Future group has assured the customers about their respective movement of ship by introducing Automatic Synchronizing system for the required Frequency which is supposed to be used by the system. That is to say there is no need for the engineers onboard to monitor, however there is automatic switching on/off which can act within 1/60 Seconds.

Investment

The financial prediction for the new type of thrusters for next seven quarters is given in the table and the cumulative profit has been shown in the graph with respect to the time.

In the first for four quarters we are only producing 92-type thrusters. In the fifth quarter we start producing 73-type thruster with very less investment as both the types belong to same product family. The 73-type are produced in number 2,4 and 5 in quarter 5,6 and 7 respectively. We start generating cumulative profit from 5th quarter and the investments are very less by the end of the 7 th

quarter. The sales, variable costs and income of 73-type are shown in addition to the 92-type from 5 th

quarter.

DEPARTMENTS IN FG:FG as an organization is divided into different departments such as commercial, technical and projects. HR, Marketing, Research and development (ETO, TOOL DESIGN), engineering, and production planning, risk management and production cell are the sub department.

ROLE OF DEPARTMENTS:Every department is with his own responsibility, finance and admistration sees finance and admistative work, HR deals with manpower availability, sales department deals with market, design department is responsible for designing the product, engineering is to convert designed products into real and check its feasibility, system engineer after the product is evaluated by engineering department and is meets required demand, production department plans production and production balancing is done so that required demand of customer should be meet with minimum utilization of resources. ROLE OF SYSTEMS ENGINEER:

Systems engineering is concerned with the overall process of defining, developing, operating, maintaining, and ultimately replacing quality systems. Where other engineering disciplines concentrate on the details of individual aspects of a system (electronics, mechanics, ergonometric, aerodynamics, software, etc.), systems engineering is concerned with the integration of all of these aspects into a coherent and effective system. Systems engineers concentrate their efforts on the aspects of the engineering process (requirements definition, top-level functional designs, project management, and life cycle cost analysis) that serve to organize and coordinate other engineering activities. The systems engineer is the primary interface between management, customers, suppliers, and specialty engineers in the systems development process.

In FG Systems Engineering is an interdisciplinary process that ensures that the customer's needs are satisfied throughout a system's entire life cycle. This process is comprised of the following seven tasks.

1. State the problem. Stating the problem is the most important systems engineering task. It entails identifying customers generally the ship owners, understanding customer needs (ship function as ship require dynamic positioning thrusters, easy installation of thrusters), establishing the need for change (shorten lead time, accurate positioning), discovering requirements (swing up thrusters can rotate at 360 degree can be used for accurate positioning) and defining system functions (for example functions of thrusters as transit, manoeuvring and dynamic positioning).

2. Investigate alternatives. Alternatives are investigated and evaluated based on performance, cost and risk.

3. Model the system. Running models clarifies requirements, reveals bottlenecks and fragmented activities, reduces cost and exposes duplication of efforts.

4. Integrate. Integration means designing interfaces and bringing system elements together so they work as a whole. This requires extensive communication and coordination.

5. Launch the system. Launching the system means running the system and producing outputs -- making the system do what it was intended to do.

6. Assess performance. Performance is assessed using evaluation criteria, technical performance measures and measures -- measurement is the key. If you cannot measure it, you cannot control it. If you cannot control it, you cannot improve it.

7. Re-evaluation. Re-evaluation should be a continual and iterative process with many parallel loops.
