Both options are 12x6 m (72 m2) flat plates, equivalent to a boat about 12 m (40 ft) long.
Option 1: Serial Scheme:
- Utilizes 160 m of resin pipes, 132 m of feed lines, and 22 inlets.
- Infusion Time: 44 minutes
Option 2: Fish Scheme :
- Involves 22 m of resin pipes, 78 m of feed lines, and 3 inlets.
- Infusion Time: 28 minutes
It's important to note that in most cases, the serial scheme proves to be impractical. The serial scheme not only uses 300% more resin (or $300) compared to the fish scheme (limited to inside pipes and feed lines), but it also poses a higher risk of leaks due to the presence of 22 inlets. Additionally, the labor required to load consumables and detect leaks further adds to the inefficiencies.
By using the serial scheme, shipbuilders may incur unnecessary expenses ranging from $600 to $1200 per boat. To avoid such wastage, it is highly recommended to carefully calculate your process and minimize material waste.
Despite the drawbacks mentioned, the question remains: why do many shipbuilders still opt for serial infusion schemes?
