102 General Description

This ship is an Oil Product / Chemical Tanker designed primarily to load and carry petroleum product oil and

IMO type II chemicals. The deadweight of the vessel is approx. 7500 metric tons at design draft. All cargo

tanks shall be able to fully load cargoes with specific gravity up to 1.52 mt/m3. The cargo tanks shall be

suitable for cargo with NO flash point limitation.

The vessel shall be designed to meet the requirements of providing world wide trading service to transport

Product Oil/Chemicals. The vessel shall be designed as modern looking chemical tanker with a totally enclosed

bridge and separate funnel, a free fall boat on stern and a streamlined bulbous bow construction. The design

shall be approved by the Buyers prior to the construction.

There are seven pairs of cargo oil tanks with two deck cargo/slop tanks, they are of mild steel with internal

surround coat. Seven pairs of ballast tanks are arranged at the wing tanks and double bottom tanks within the

cargo oil space. Fore peak shall be used as water ballast tanks as well.

Sixteen sets of deep well type pumps driven by separate electric motors controlled by frequency converters and

controlled from the cargo control room. are provided to handle the cargo loading/unloading. The rpm of the

cargo pumps drive elec. motors shall be adjustable between the allowable minimum and maximum rpm. The

cargo loading/unloading piping system is able to load and discharge sixteen (16) different grades of cargo oil

or chemicals simultaneously without contamination. The cargo lines for all cargo tanks shall be provided.

Technical Specification of 7500 DWT IMO II Chemical Tanker

Page 11 of 118

Interconnections of discharge lines with proper isolation valves for stern discharge is allowed. (Buyers to

provide piping diagram as reference)

The cargo details shall refer to the agreed Cargo Diagram

One pair of deep fuel oil tank in double bottom and double side shall be arranged in engine room forward. The

engine room to be separated from cargo spaces by means of ballast pump room. Seperation of fuel oil and

lubricating oil from direct contact with the sea as required by CLEAN SEA notation to be allowed.

Propulsion is provided by means of two marine diesel medium speed engines located in the engine room after.

Two controlled pitch propellers are installed and are driven by reduction gearboxes and flexible couplings.

Maneuvering is accomplished via two balanced flap type or fish tail type rudders (Barkemeyer) and one

electrically driven bow thruster, meeting ICE Class 1A requirement..

Electrical power may be generated by shaft generator during voyage, how ever the speed of the vessel will be

affected accordantly if shaft generator is used. One generator when idle in port. For discharging with four

cargo oil pumps two generators should be used. Emergency generator can be used parallel with three main

generators and the two shaft generators with auto-load sharing.

Accommodation for 16 crews is provided at the after of the ship. In order to reduce the vibration and noise,

crew's accommodations, bridge, etc. shall be located at the forepart of deck house, funnel shall be arranged on

accommodation deck.

One light mast shall be arranged at the end of forecastle, one signal mast (radar mast) shall be arranged at the

top of the bridge. And also one light post shall be provided near the midship manifold, port and starboard
