After block erection: The erection welding seams and damaged primer shall be grinded to ST3 and touched up according to specification, except for liquid mud tanks where the erection welding seams shall be blasted before applying the required painting scheme No paint is to be applied over the shop primer until the air tightness test of the tank or cofferdam concerned has been carried out and approved. Were shop primer thickness exceeds 40 µm, it has to be grinded before testing.
Before applying the paint over the shop primer and between different coats: (Unless otherwise indicated for the particular area- see 271 to 286-) Remove all weld spatter, smooth weld seams and sharp edges. Fresh water wash or degrease as necessary to remove all dirt and contamination. Ensure area is clean and dry prior to application and verify that thickness of the previous coat (including shop-primer is within the recommended values. Clean welds, damaged and corroded shop primer by blasting to SA 2 ½ or by power tooling to St 3
All areas shall be touched up with understroke paint before top coat is applied. This also applies for the equipment delivered undercoated from the subcontractors.

The correct and suitable combination should automatically be established. In case of starting of big consumers the available power should automatically be checked and if necessary the stand by diesel generator should be started automatically and connected to the switchboard. As soon as available power is accepted, the big consumers should start. An estimate of 12 heavy consumers should be needed. If the power consumption on the main switchboard has decreased and should be covered by smaller number of generator set, the generator of lowest priority should automatically be loaded off, disconnected from switchboard and stopped. The operations shall be provided with certain delays. Each generator set shall automatically shut down in accordance with the manufacturer’s design criteria. A shut-down condition shall be identified by an alarm connected to the IAS alarm and monitoring system..

Automatic/manual synchronizing, automatic load sharing device, frequency control, preferential tripping and automatic generator management for alternators shall be provided. Shaft generators The shaft generators should only be used when requested shaft power is available on the main engine and the engine speed is locked in constant speed mode. The PMS system shall carry out synchronizing, closing and opening of generator breaker. Blocking of heavy consumers When a heavy consumer receives a start signal, the PMS will check if there is enough available power on the bus bar. If sufficient power is available on the actual bus bar, the consumer will start immediately. If there are not enough power available on the actual bus bar, a new diesel engine will start and connect the bus bar, or a shaft generator breaker, or a bus tie breaker will close (depending of PMS mode) to obtain the additional required power. Then the heavy consumer will start immediately. Preferential Trip When the running generator (s) is overloaded, non-essential consumers shall be automatically tripped to prevent the complete power failure of the Vessel. This shall be included in the PMS system, and the trip will affect only the consumers on the affected busbar. The preferential tripping system of non-essential consumers shall be arranged as follows: If busbar frequency relay detects under-frequency (setting 57Hz, delay 10sec.) of the generators If generator load relay (kW and/ or current) detects generator overload above 100% load (delayed 20 sec.), If generator load relay (kW and/ or current) detects generator overload above 107% load (instantaneously trip) The following non-essential consumers shall be tripped in the MSB: Base Oil, Liquid Mud, Brine, FO Cargo and FW cargo pumps Compressors for dry bulk cargo handling HVAC system (A/C compressors and heating element) Galley equipment The following non-essential consumers shall trip in the ESB: Fan heater for em. generator room
