ANCHOR MANAGEMENT (TENAGA TIGA)

DATE : 31st 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 air 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 8th shackle to the 4th shackle, where kinks / twists were discovered along the chain

 Noted twists in the anchor chain, the most severe between the 8th to the 7th shackle where a mass of foul chain were observed. At each point the kinks were cleared

 From the 6th 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 before we start to lower (S) stbd anchor until 2 shackles in the water as we decided to swap the anchor.

 The (P) chain was further lifted until port side anchor secured.

 The (S) chains later were lowered until 8th shackles in the water.

 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
