Vessels that is under layup (without handing over) and maintained by Roving team.

CLASS STATUS DURING LAY-UP
1. Class Notation & Status of Layup vessels (to obtain sampling).
2. For vessel in Cold layup, are the ISM & ISPS certificates withdrawn?
INSURANCE ISSUES
PROTECTION AND INDEMNITY COVER - Does local port authorities require a letter from local P&I club representatives to confirm that the laid-up vessel is covered for port risks (e.g. oil pollution, wreck removal, and salvage costs)?
HULL AND MACHINERY COVER - Opt for a laid-up return of premium; or with the underwriter’s agreement, cancel the trading policy and substitute this with a ports risk policy
HV EQUIPMENT
BREAKERS, BUSBARS AND SWITCHBOARDS - All high-voltage (HV) breakers were withdrawn for a detailed visual inspection of terminations, spouts and mechanical linkages.
BREAKERS, BUSBARS AND SWITCHBOARDS - All protective relays and master trip relays should be inspected and electrically tested in accordance with the Rules. They should then be removed, sealed and kept in dry storage. The exposed openings in the switchboard should be sealed to prevent ingress of moisture and contamination.
PROPULSION MOTORS, CONVERTERS AND GENERATORS - With the equipment de-energised and isolated, a fully detailed visual inspection was undertaken.

1. SAFETY CONDITIONS

1.1 Safety conditions to be kept throughout the lay-up period include but not limited to:
1. Power supply
2. Manning
3. Fire protection and fire fighting
4. Protection against explosion or flooding
5. Prevention of failure of mooring or anchor
6. Safety equipment
7. Emergency power

2. MOORING ARRANGEMENTS

Vessel arrangements

How are the vessels arranged?

SHIPS MOORED IN GROUPS
When ships are to be laid–up in groups, mooring arrangements should be in with the following additional requirements:
1. Adjacent ships should be similar size to avoid differential surging motions and they should be ballasted to similar freeboards to permit breast lines to be directly led.
2. The fore and aft direction of each vessel should be parallel to the prevailing string winds.
3. Breast mooring lines should be provided, sufficiently tensioned and of similar stretch characteristics.
4. Sufficiently sized fendering arrangements be provided alongside at areas of possible contact with other ships of shoe structures.
5. If the auxiliary engine on one vessel is used to supply power to other vessels, it is preferably that all other vessels are electrically connected to avoid stray currents.
SHIPS MOORED IN INDIVIDUALLY
When ships are to be laid–up individually, mooring arrangements should be in with the following additional requirements:
1. When ships are laid-up to buoys or anchored, they should be moored to prevent swinging in winds or as a result of tidal changes.
2. When ships are anchored, the chain cables must not be capable of twisting or cross contact, and anchors must be placed to prevent tripping.
3. Anchor cables should be led and protected to prevent chaffing against the ship.
4. If laid-up ships are subjected to wave movement or surge, anchor cables should be periodically moved at intervals to shift points of wear on the cables.
5. Anchored ships should have ample chain scope – i.e., the local port authorities should be consulted for their knowledge of prevailing conditions.
6. Anchor lights and fog signals should be fully operational and additional deck lighting will be required if lay-up near shipping lanes.
7. Ships should be sufficiently ballasted to reduce windage, roll and surge, with due regard to hull stresses. Furthermore, when draught is finally established, it is advantageous to paint clearly visible reference marks at bow and stern, just above waterline as an external indicator of hull integrity (leakage).
8. An emergency means of quick release of all moorings should be provided and arrangements for towing should be readily available if propulsion machinery cannot be brought into operation
