Dynamics Analysis of Single Buoy Mooring in Malaysian Waters
In the paper a catenary anchor leg mooring (CALM) buoy moored in a water depth of 1,200 m is considered. The purpose of this CALM buoy is to provide an offloading point for transferring oil from an floating production storage offloading (FPSO), which is moored at a distance of approximately 1 nautical mile, to a shuttle tanker.

Mooring System | SpringerLink
The major difference between a catenary mooring and a taut leg mooring is that where the catenary mooring arrives at the seabed horizontally, the taut leg mooring arrives at the seabed at an angle. This means that in a taut leg mooring, the anchor point has to be capable of resisting both horizontal and vertical forces, while in a catenary ...

Single-Point Mooring | SpringerLink
Catenary Anchor Leg Mooring System (CALM) With the growing crude oil trade, petroleum products are transported around the world. For coast area, the application of catenary anchor leg mooring system (CALM, Fig. 15) is preferred. CALM systems are used for temporary mooring of crude shuttle tankers for the purpose of loading and …
Single Point Mooring
Single-point mooring (SPM) systems are designed to accommodate deep-draft tankers while they transfer crude oil and fuel oil to and from shore. Three typical designs are shown in Fig. 4: a single anchor leg mooring (SALM), a catenary anchor leg mooring (CALM), and an articulated column system. At present there are about 50 SALM and 150 CALM ...
SPM (Single Point Mooring) or SBM Operations
The two main types of mooring configurations for SPMs are Catenary Anchor Leg Mooring (CALM) and Single Anchor Leg Mooring (SALM). CALM holds the buoy in place by anchor chain that extends in catenaries to anchor points some distance from the buoy. The SALM system is similar, except that the SALM is anchored by a single anchor leg.
Evaluation of the Safe and Failure Zones of Mooring and
The mooring and riser system is the most critical part of an offshore oil terminal. Traditionally, these two parts are designed separately without considering the nonlinear interaction between them. Thus, the present paper aims to develop an integrated design process for riser systems with a lazy-S configuration and mooring systems in the …
