ANCHOR MANAGEMENT TIGRIS LEADER

DATE : 28th January 2010


Moving the anchor chain

• The (P) anchor chain was lifted to a safe length in order to remove the point of torsional stress and check for kinks / fouling of the anchor chain. Hydraulic system and water cooled.

• Anchor secured to 10 shackles outside the hawse pipe. (P anchor)

• The anchor windlasses were tested without load prior operation

• (S) anchor prepared for emergency release in gear and on the brakes above water level

• (P) anchor lifted and found fully covered with barnacles. The water exposed vertical portion of the chain (approximately to the 9th shackle – point of entry into the seabed)

• After the 9th shackle the chain found relatively free from marine growth and covered only with thick mud

• Each shackle was lifted and from the 7th shackle to the 4th shackle, where kinks / twists were discovered along the chain

• Noted twists in the anchor chain, the most severe between the 6th to the 4th shackle. At each point the kinks were cleared

• From the 7th shackle onwards as the chain was lifted the twist were found running along the length of the shackle until the 4th shackle. The twists were systematically cleared

• The (P) chain was further lifted to 2 shackles in the water and lowered back again to 8 shackles outside the hawse pipe.

• Upon completion (S) anchor was secured with the stoppers down and brakes tightened.



Additional remarks

• Greasing of windlass machinery carried out during the operation

• Training given to personnel for familiarity with machinery and safe precautions when handling anchors and related machinery.

• Vessels position holding steady and GPS readings checked throughout the night
