Lesson Fourteen
Planning,From Contract to Working Plans
Planning
Delivery of a completed ship by a specified date requires careful planning,Following the introduction of the critical path method of planning and control by the U,S,E,I,du Pont de Nemours & Company1 about 1959,new techniques were adopted in many shipyards.
The critical path method is the basis of network analysis,which is used in planning complex production projects,The network,and information derived from it,is used for overall planning of a project and also for detailed planning with production progress control.2 The network gives a logical,graphical representation of the project Each element of work is represented by an arrow,the tail of which is the starting point of activity and its head the completion.3 The arrows are drawn to any suitable scale and may be straight or curved,An event,which represents the completion of one activity and the beginning of another,is usually indicated by a circle and described further by a number within the circle,But each activity need not be completed before the next activity is begun,T he logical order of steelwork in a hull,for example,is,⑴ detailed drawing of steelwork; ⑵ ordering of steel; ⑶ manufacture and delivery of steel;⑷ storing of steel material in stockyard; ⑸ shotblasting,cleaning,and forming operations; ⑹ subassembly work；and ⑺ erection of structure on berth,These operations can be represented on a ladder type of diagram,Many such diagrams—ladder and other types—go toward making up the complete aggregate operation of building a ship,When the proper sequence of operations is decided upon,times must be allocated to each operation to ensure that the men in charge understand their obligations,Planning,based on realistic estimates of times an costs,must begin at the precontract stage,so that,scheduled dates for each major section,is available,Detailed networks must be prepared for each of the major sections,showing dates for completion,The earliest and latest permissible starting and finishing times are indicated for each activity.
The critical path of a project is a series of activities whose duration cannot be increased without delaying the completion of the project as a whole,In large networks there may be more than one critical path,Up to about 100 activities can be dealt with manually but,for more complex cases,the numerical work is done by computer,The spare time available for a series of activities; i.e.,the maximum time these activities can be delayed without retarding the total project,is aggregated into a,total float”,This is regarded as a factor of safety to cover breakdowns,mishaps and labour troubles,Intelligent and experienced use of critical path methods can provide information of great value,Savings in production costs depend upon the use that management makes of this information.
From contract to working plans
Before an order is placed,The main technical qualities of the ship are decided upon and a general-arrangement drawing of the vessel,showing the disposition of cargo,fuel,and ballast,and crew and passenger accommodation is prepared,This plan provides a complete picture of the finished vessel,It is accompanied by detailed specifications of hull and machinery,This general-arrangement plan and the specifications form the basis of the contract between shipowner and shipbuilder.
As soon as an order is confirmed,drawing offices and planning departments produce working plans and instructions,Since ships are usually constructed according to the rules of a classification society,the stipulated structural plans are normally submitted to the society for approval,The spacing of bulkheads in passenger ships,for example,must be approved by the appropriate authority,For all ships,passenger and cargo,the approval of the maximum permissible draft must be sought from the classification society,Necessary working drawings include the line plan and detailed plans of the steel structure—shell plating,decks,erections,bulkheads,and framing─as well as accommodating spaces,plumbing,piping,and electrical installations,and main and auxiliary machinery layout,The planning and production department prepares a detailed progress schedule,fixing dates for the completion of various stages in the construction,A berth in the yard is allocated to the ship,arrangements for the requisite materials,labour,personnel,and machines are made,and precautions are taken to ensure that the many interrelated operations will progress according to the timetable.
