Marine Boat Anchors

Anchor

Anchor generally refers to ship anchor, which is the main component of anchoring equipment. The iron boat anchoring equipment is connected to the boat with iron chains, and the anchor is dropped to the bottom of the water to make the boat stop stable.

There are many types of anchors, and large holding power anchors are commonly used in drilling platforms, as shown in Figure 1. The main feature of this anchor is that its grip can only be guaranteed when the pulling force is horizontal. If the pulling force has a vertical component, the grip is reduced, and the anchor claw will be pulled out of the soil. Experiments show that the grip force of the anchor handle turned up 6° began to decrease, and the grip force of the anchor handle turned up 12° decreased significantly. Therefore, the lower end of the anchor chain must be tangent to the seabed when anchoring, otherwise there is a danger of anchoring. Lifting the anchor is to take advantage of this feature. Pull the anchor chain upward to lift the anchor handle. The anchor loses its grip and finally breaks out.

The choice of anchor should consider convenient operation, convenient storage and economical application, but the most important thing is the holding power of the anchor. On the one hand, the holding power of the anchor is not known because of the different types of anchors, on the other hand, it is related to the soil quality of the seabed.

With the advancement of ocean development to deep water, new requirements are put forward for anchoring. In deep water, if the lower end of the anchor chain is still required to be tangent to the seabed to ensure the anchor's grip, the required chain is very long. Therefore, it is necessary to study anchors that can withstand vertical component forces, such as cement weights or anchor piles. When piles cannot be driven under lithological seabed, bored cast-in-place anchor piles can be used. Some anchors are designed according to the specific seabed, and the working performance of the anchor is poor when used in the seabed situation that does not meet the design requirements. Although there are formulas for calculating the holding power of various anchors under different seabed conditions in Figure 1, the true holding power of the anchor needs to be determined through field tests.

Equipment composition of windlass

The windlass is mainly composed of base, support, anchor sprocket, brake, sprocket, gearbox, electronic control system (except manual windlass), etc. The electric windlass has a motor, and the hydraulic windlass has a hydraulic pump station.

The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several speeds, and the electric system.

The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120 degrees.
