QUESTION $3$

A rectangular box barge has dimensions as per the diagrams shown below. It is divided transversely into a port and starboard section and longitudinally into four sections of eight equal sized tanks for carrying fuel of RD $=0\mathrm{.}9.$ It is designed for operation in seawater and has a light displacement of $1200$ tonnes.

At load displacement it is trimmed $0\mathrm{.}3$ m by the head, LCF is amidships, $\backslash (\backslash$mathrm$\{$GML$\}=40\backslash$mathrm$\{$~m$\}\backslash ).$

LCoG and VCoG of each tank is located at their centers.

Determine

a$)$ KM when all tanks are loaded to the statutory ullage of $\backslash (2\backslash \%\backslash )$ remains.

b$)\backslash (\backslash$mathrm$\{$GM$\}\_\{\backslash$mathrm$\{$vcoG$\}\}\backslash )$ at load if the corresponding KG is $4\mathrm{.}88$ m

c$)$ Reserve buoyancy $\backslash \%$ at load displacement.

d$)$ From a fully loaded condition, the barge transfers all the fuel contained in tanks $\backslash$# $1,\backslash$# $2,\backslash$# $6$ to a ship. What is the trim after transfer?
