A cargo ship has LBP 130 m, LCF 4 m aft of amidships and floats at 4.6 m and 4.2 m draught at FP and AP respectively. Its TPC is 22.6 tonnes while MCTC is 154 tonnes.m. If the following items are loaded and unloaded: UNLOADED 120 tonnes cargo from 50 m fwd of amidships 90 tonnes cargo from 30 m aft of amidships 80 tonnes cargo at amidships LOADED 60 tonnes cargo at LCF 90 tonnes fresh water at 25 m fwd of amidships Calculate: (a) Parallel rise (2 marks) (b) Total change in trim (8 marks) (c) Change in trim fwd, ??TF (3 marks) (d) Change in trim aft, ??TA (3 marks) (e) Final draught at AP (2 marks) (f) Final draught at FP (2 marks)

Step 1
- Unloaded: 120 tonnes + 90 tonnes + 80 tonnes = 290 tonnes - Loaded: 60 tonnes + 90 tonnes = 150 tonnes - Net change = 290 tonnes (unloaded) - 150 tonnes (loaded) = 140 tonnes (unloaded) Show more…

8. A ship of 12,500 tonnes displacement, KM 7 m, KG 6.4 m, has a 3-degree list to starboard and has yet to load 500 tonnes of cargo. There is space available in the tween decks, centers of gravity 6 m each side of the centerline. Find how much cargo to load on each side if the ship is to complete loading upright. tan(3°) = GG / GM Moments about the centerline: Wd (Listing moment) to port (+ve) Wd (Listing moment) to starboard (-ve) +12,500 + w + 500 - w (final moment) W tonnes to starboard and W tonnes to port

A ship of 7800 tonnes displacement has a mean draft of 6.8m and is to be loaded to a mean draft of 7 meters. GM is 0.7m and TPC is 20 tonnes. The ship is currently listed 4 degrees to starboard. How much more cargo can be shipped in the port and starboard tween deck, with centers of gravity 6m and 5m, respectively, from the centerline, for the ship to complete loading and finish upright.
