3.13.1 APPLICATION

This document is applicable to Vessel Managers, Masters, Chief Engineers, and Chief Officers for fully managed vessels.

3.13.2 PURPOSE

The purpose of this document is to highlight items that must be checked and verified to be in order during reactivation, after a docking or repair, and during sea trials.

3.13.3 TESTING REQUIREMENTS

3.13.3.1 General

On completion of Dry Docking or Shipyard Repair in the yard the following procedure should be taken by the Vessel Manager for re-commissioning of the plant and preparation of the vessel to sail:

• Notify local port authorities via agent in advance with tentative ETD.
• Notify the Classification Society and check any pending requirements to fulfil prior to leaving the yard.
• Ensure that the Statutory, Classification & other relevant Certification and Documentation have been updated and are valid.
• All temporary arrangements or installations should be removed such as temporary drying, heating and ventilation systems as well as locking of valves or temporary anode installations.

3.13.3.2 Ballast / Cargo Tanks

• Tanks are to be carefully inspected and particular attention paid to ensure that material used for repairs have been removed, debris cleared & hydraulic connections to the valves are secure.
• Heating coils in way of cargo tanks should be blown through by steam or air and pressure testing completed. Supporting clamps are to be in place and secured.

3.13.3.3 Safety Equipment

• All LSA/FFA Equipment should be checked to the satisfaction of relevant authorities.
• Particular attention should be given to emergency and firefighting systems.

3.13.3.4 Machinery

• Samples of lubricating oil should be submitted for full analysis.
• All systems should be checked for completeness and sufficient operation.
• Representative samples of all fuel oils kept on board should be taken and thoroughly analysed prior to use in diesel engines.

3.13.3.5 Boilers

• All safety measures and emergency shut-off should be tested.
• Direction of valves overhauled must be checked after installation. Gauge glass valves are opened in correct direction.
• Fuel oil should be circulated through the oil burning system.
• Care should be taken to proceed slowly when raising steam production.

3.13.3.6 Main Engines

The basic inspection to be conducted prior testing of the engine:

• At least one cylinder unit with gear as well as two (2) main bearings should be surveyed and confirmed to be in normal condition.
• Cooling water for jackets and pistons (if applicable) should be circulated and checked for leakage.
• Check the crankshaft deflection after docking and compare with the one before docking, and the engine maker’s allowances.
• Fuel valves should be cleaned and adjusted and the fuel system checked for leakages.
• Thorough checks and crankcase inspection should be carried out by the Chief Engineer and/or Vessel Manager before finally closing the crank case for preparing the main engine for operations, when any maintenance is carried out by any external party in the crankcase.
• Completeness of the work, integrity of all bolts and locking, and absence of any foreign materials or other abnormal conditions, should be ascertained before closing the doors.

3.13.3.7 Electrical Equipment / Control & Instrumentation

• All circuits should be checked for insulation resistance to earth.
• All electrical cables and equipment should be examined.
• Overload trips of all generator breakers should be checked for satisfactory operation.
• All essential control systems, monitoring instrumentation, limit alarms and emergency shut-offs are to be verified in order.
• Switchboard must be cleaned and bus bar connections must be checked for tightness with torque spanner.
• Transformers must be changed over.

3.13.3.8 Navigation

• All navigation equipment should be verified, tested in good order.
• All required charts and publications should be up to date.

3.13.3.9 Testing

• Main engine safety alarms
• Engine should be run ahead and astern by engine room and bridge controls, including testing of shut-down and slow-down functions
• Auxiliary engines with connected automation equipment
• All pumping, pneumatic and hydraulic systems
• All alarms covering ME, Auxiliaries with steering gear
• Remote operation of fuel oil and lube oil, pumps and valves
• Cargo and ballast pumps
• Bilge pumping systems
• All communication systems
• Steering gear, including emergency operation
• All deck machinery and equipment
• All navigation and sounding lights and signals

3.13.3.10 Special Focus Testing Requirements:

• Emergency Fire Pump – Check the priming unit and ensure the pump is taking suction.
• Emergency Generator – Testing on load by simulation is carried out.
• Emergency Air Compressor – Running test to be carried and ensure the emergency air bottle is getting pressurised.
• Emergency Switchboard – Check all insulation and when testing emergency generator on load, check all power distribution from emergency panel are in order.
• Steering Gear Pump & Motor – Test motor insulation, oil level, isolation valves are open/close for correct operation. Motor/pump coupling to be checked. Running test of S/G on all modes is to be verified.
• Lifeboat / rescue boat / fast rescue boat – Ensure secured properly and all LB equip/provisions are placed. Test run Lifeboat Engine.
• Quick Closing Valves – Check air/hydraulic pressure and all valves in the system are kept open.
• Fire Dampers / Flaps – Check air/hydraulic pressure and all valves in the system are kept open.
• GMDSS Equipment – Check function of Inmarsat C – transmitting/receiving messages.
• Radar – X Band & S Band – Check no lashing or any yard obstruction on scanner unit before starting. Carry out performance test.
• ECDIS – Carry out performance test and verify synchronization with the Gyro Compass.
• M/E Crankcase Oil Mist Detector – Check air is opened and ensure that sample drawn from all units on rotation.
• Oil Discharge Monitoring Equipment – Carry out self-test.
• 15 PPM Oily Water Separator & Monitor – Function test of 3 way overboard v/v is checked and is locked and sealed.

4. Trials

In addition to the operational tests of individual units of machinery, a dock trial and subsequent sea trial should be done.
