Log Book -Week 6

Work Week: 6  ( Date: 16 – 20 July 2018)

16 July

(Monday)

• Given a 36m standby ship drawing( general arrangement and lines plan) by En Sharul to study its stability.

• Download software Veristastability
• Teach by En Sharul how to use the software, including

1.  Project data (Insert the data correctly as will be used later)

      2.Create lines plan based on the client line plan

• Aft Side, including Profile, Deck knuckles, Deckline, Side knuckle and station

17 July

(Tuesday)

• Fore Side, including Profile, Deck knuckles, Deckline, Side knuckle and stationCreate Shape

      3.Check the shape and modify the error

      4.Check the hydrostatic value

The error is calculated by comparing the designer value from the stability booklet and the software (Veritastability) value.

Based on the IACS, the tolerances of displacement is 2% whereas the tolerances of LCB is 1%.

**Check by using excel (The design draft =2.35m+-1m is more important)

Since the tolerance around the draft is within the range, the ship shape can be used.

18 July

(Wednesday)

• Given drawing (structural profile and section detail) by En Sharul

• Teach by Shah and En Sharul of the compartment.

      Manage compartment ( Click the tank used in the ship)

 BHD's definition ( Create longitudinal and traverse bhdhead to separate the tank/compartment)

Part defination (creating part based on the bhd created)

19 July

(Thursday)

• Done all the compartment in the ship.

• Check the capacity by comparing to the capacity plan in the stability booklet.

20 July

(Friday)

• The overall length of the ship is 36m. Any ship of 24m in length or over should apply weather criteriomn. (wind and rolling criterion) 
• Hence, the windage area is drawn by scale down the drawing
