The elongation of each mooring line and deflection of each breasting dolphin can be calculated from the amount of surge, sway and yaw at the center of the tanker. Since the tanker is essentially a rigid element, each chock through which a line passes effectively moves in relation to the mooring point thus changing the [...]

Posted by author on June 30th, 2008
A tanker at a jetty or a sea island is held in the berth by a combination of mooring lines and breasting dolphins which resist the forces applied to the tanker by wind, current, waves and other environmental factors.There are multiple mooring lines which connect from several locations on the ship to several mooring points [...]

Bight- A loop form by doubling back a rope upon itself.
Bitts – Vertical post or bollards mounted in pairs around which a line can be secured.
Bollard- A vertical post to which the eye of a mooring line can be attached.
Breast lines- Mooring lines leading ashore as nearly perpendicular as possible in a ships fore and [...]
