Description
본 발명은 해양 구조물의 물량 산출 방법에 관한 것으로, 보다 상세하게는 해양 구조물의 특성상 설계와 생산이 동시에 진행되는 것에 따라 설계 단계에서 물량의 산출을 간편하게 하고, 구조물 변경에 따른 자재 사이즈 변경을 용이하게 적용할 수 있도록 해양 구조물의 물량 산출 방법에 관한 것이다.
The present invention relates to a method for calculating the quantity of an offshore structure, more specifically, the design and production of the offshore structure at the same time as the design and production proceeds at the same time to simplify the calculation of the quantity, easy to change the material size according to the structure change The present invention relates to a method for calculating the quantity of offshore structures for application.
일반적으로, 해양 구조물 제작의 특성상 설계와 생산을 동시에 진행하여야 하는 바, 수주된 구조물의 종류별(Fixed Type, Floating Type), 발주처 별로 적용되는 방식(Rule)이나 요건(Requirement) 등에 따라 영업 설계를 시작함과 동시에 생산 계획에서 대일정 계획을 수립하게 된다. 영업 설계가 수립되면 상세 설계를 함과 아울러 이에 따른 구매 일정을 수립하고, 다시 상기한 구매 일정과 연동하도록 중 일정 계획을 수립하게 된다.In general, due to the characteristics of offshore structures, design and production must be carried out at the same time, and the sales design is started according to the type (Fixed Type, Floating Type) and the order (Rule) or requirement applied by ordering body. At the same time, a large schedule will be established in the production plan. When the sales design is established, the detailed design, the purchase schedule according to the above, and the middle schedule plan are established to link with the purchase schedule.
상세 설계 및 중일정 계획이 수립되면 다시 생산에 필요한 생산 설계를 함과 아울러 생산에 필요한 소일정 계획을 부서별, 공종별로 수립하고 구매 자재가 입고됨과 아울러 생산을 실행하게 되는 바, 상기한 소요 자재의 구매 및 입고는 영업 설계의 시작과 함께 진행된다.Once the detailed design and mid-schedule plan are established, the production design necessary for the production is made again, and the small schedule necessary for the production is established by department and sector, the purchase materials are received, and the production is executed. Purchasing and receipt proceed with the start of the sales design.
또한, 강재를 종류별로 제때에 입고시키지 않으면 생산이 지연되므로 해양 구조물을 제때에 제작하지 못해 막대 한 금전적 손실을 입게 된다. 실제로 입고가 되어야 하는 시기가 되어서야 필요 발주량을 정확히 계산할 수 있기 때문에 이때에 필요 강재량을 구매하는 활동은 매우 큰 부담을 가지고 비용면에서도 막대한 비용을 지불해 왔다. 정확한 입고를 위해서는 실제 절단 착수일보다 적어도 4~6개월 전에 강재 소요량이 계산이 되어야 하는데 현재는 이 계산을 정확하게 할 시스템이나 방법이 없는 상태이다.In addition, if steel is not received in time for each kind of production, production is delayed, and therefore, the offshore structure cannot be manufactured in time, resulting in huge financial loss. In fact, it is only when it is time to receive the goods that the required order quantity can be calculated accurately, so the activity of purchasing the required amount of steel has been very costly and expensive. For exact receipt, the steel requirements must be calculated at least four to six months before the actual cut start date. Currently there is no system or method to make this calculation accurately.
특히, 해양 구조물의 설계시 블록별 물량 산출이 어렵고 잦은 에지니어링(Engineering) 변경에 의한 자재 사이즈의 변경 적용이 매우 어려운 문제점이 있다.
In particular, it is difficult to calculate the quantity of each block when designing the offshore structure, and it is very difficult to apply a change of material size due to frequent edge engineering.
