Dated: January 19, 1997
It has been mutually agreed between the Buyer and the Builder that
notwithstanding what has been previously agreed and for an additional cost of
US$ 100,000 per vessel, which will be added to the contract price and payable on
delivery of each vessel, the Specification has been amended as follows:
1. The specified salt water engine room machinery cooling system
(including the air conditioning plant) will be replaced with a central
flesh water cooling system. The central fresh water cooling system
will consist of a short sea water cooling circuit (with 2 plate
coolers in parallel) - cooling a long fresh water cooling circuit
serving all machinery, coolers and heat exchangers in the engine room.
The short sea water cooling circuit including all valves and fittings
will be constructed of salt water resistant material such as cunife
(except main sea water line which to be galvanised steel pipe) and the
fresh water circuit of mild steel. All major coolers will be of plate
type with plates constructed of titanium on the salt water cooling
circuit and stainless steel on the fresh water circuit. The Builder
will endeavour to install a plate cooler as the auxiliary condenser
however if such plate condenser is not available the Builder will
install a suitable tube cooler. The Builder will provide the Buyer
with further details of the proposed arrangement for their approval.
2. The hull coating and cathodic protection system outlined in Section 3
of the specification is amended so that it will comply with the
requirements of Class for In Water Survey (IWS) and will provide that
the vessel need only drydock every 5 years for Class renewal and
recoating. Accordingly the Builder will provide an impressed current
system and all other requirements to meet Class requirements.
3 The Buyer will provide at his own expense a third compressor of 50% of
the design capacity (125KW - 107,500 ▇.▇▇▇/hr) for the prescribed air
conditioning system in the accommodation. At no additional cost to the
Buyer, the Builder will install and arrange the three compressors in
the engine room so that any two of the three compressors can run the
system at any time with the third being in standby.
4. In order to safely operate the remote control ballast system from the
Cargo Control Room, the Builder will provide remote ballast pump start
and stop controls and appropriate suction/pressure gauges at the
ballast valve control station (mimic board).
5. The fuel oil transfer pumps prescribed in Section 7.10.3.1 shall be
rearranged such that the diesel oil transfer pump will be of the same
capacity as the heavy fuel oil transfer pump. In the event of the
failure of either pump they will be interchangeable for either fuel
system.
6. The Steam Generation Plant prescribed in Section 7.4 is amended to a
smoke tube composite boiler manufactured by Shazhou Boiler Works in
co-operation with ▇▇▇▇▇. The Builder will provide the Buyer with
detailed drawings of the amended arrangement for approval. As the
composite boiler is now smoke tube type on both sides, the soot blower
prescribed in Section 7.4.2.4 is deleted.
7. Section 8.2 - Main Diesel generators - it is agreed that the structure
and number of bearings will be as per manufacturers standard.
